Ultimate Guide to Filament Problems in 3D Printer Extruder

3D printing out of Filament silk? These steps teach you to solve quickly!

The Filament of the disc is jammed, which can cause the silk to be impeded?
3D printing out of Filament, why?

No Filament when printing;
Insufficient amount of Filament;
Fault generating;


Once the Filament is not smooth, you need specific analysis of the specific problems, one by one to investigate the reasons:
Is the disc sticking?


Is the print nozzle plugged?

If the print nozzle is blocked, follow these steps:

1. heating print head, from the print head to take out the material (Note: be sure to print the head in the case of heating out of the material, under the cooling state forcibly pull out will lead to more serious congestion);

2. Use a steel wire with a diameter smaller than the nozzle or a minimum six inner angle wrench to clear the nozzle;


3. the nozzle temperature manually raised, manually to the throat extrusion Filament, so that nozzle normal spinning;

4. pull out the Filament, the Filament is inserted into the pipes again, such as Filament melting out, repeated several times until the final Filament smooth (the purpose is to make the semi molten wire residue in nozzle blockage or adhesion out);

If the above method can not be solved, you need to remove the print nozzle:


1. Remove the nozzle and heat the part of the adhesive material in the nozzle with the spray gun. Clean the materials and impurities sticking to the nozzle;

2. after cleaning or replacement nozzle re installed, and if the yarn is not smooth, we should consider whether the need to replace the pipe inside the PTFE tube, if the PTFE tube deformation, it will cause serious plug;

3. reinstall the print nozzle, you can smooth out the Filament;

Alunar 3D Printer Extruder adopts new structure, nozzle is easier to assemble and disassemble, avoid plug problem from the source. In addition to the filament is also very important, good quality filament to a great extent, can avoid this problem.

Top 5 Tips You Have to Recognize the 3D Print Follow-up Processing Problem

The advantages of 3D printing are undeniable, but when it comes to the cost of post-processing, it often becomes a big headache".

Not long ago, Rize, a start-up in Boston, USA, has just launched an industrial class desktop 3D printer called Rize One, which is known as a print product that can be used directly without the need for post-processing. It is by virtue of this big bright spot, Rize One quickly caught a lot of 3D printing enterprise appetite. Before launching the research, Frank Marangell, chief executive of Rize, said that the innovation degree of rapid prototyping technology and materials was reflected in strength, surface accuracy, color, zero post-processing and environmental protection.

But the real research, senior practitioners the former vice president, chief executive of Rize, the Stratasys operation, suddenly feel that the real key should be postprocessing this link with rapid prototyping the most in the crowd is used in the fixture and mould manufacturing, and these people are longing for a can help them quickly complete the postprocessing plan. The post-processing of the FDM process requirements is relatively simple, but the supporting structures must also be removed and then polished, polished or sprayed:

A 3D printing model may take half a day to soak in a sodium hydroxide solution to remove the support material.

FDM post-processing is not only harmful to the environment, but also difficult for operators. You have to wear gloves and pliers. But after doing this post-processing, the parts that come out can easily let you PK other programs:

Such as light cured (SLA), after printing, need to soak in alcohol, and then use UV light curing, and then to support, grinding. Selective laser sintering (SLS) is compared to Frank Marangell for "archaeological excavation". You have to slowly remove most of the powder in a sealed chamber and rinse it with water.

In addition to making the components more robust, Rize One will be in print in the supporting structure between it and print a rejection of the ink jet itself is called Release One, which can support the removal of ink made easier (only 30 to 45 seconds), but will not affect the print quality. In addition, it uses a unique enhanced polymer deposition (APD) technology that can change the nature of each print element, producing a uniform object that is 2 times the strength of the FDM print.

The Rize One desktop 3D printer in the Beta test phase shortens the post processing time from a few hours to less than a minute.

Some post-processing even takes several days. Such a time-consuming cost is enormous, so Rize One commissioned a manufacturing consultant Todd Grimm to do a special report on the impact of postprocessing on 3D printing. Here are 5 main aspects of this report that show the cost of 3D post processing:


1. Waste of Production Time

The report showed that the 3D print time increased by 6 hours each, and the post processing time increased by 1 hours.

If your company also needs to do post-processing, 3D printing can not break the bottleneck of time, but may extend the product listing time.

"Because the postprocessing block, Newell Rubbermaid efficiency 3D print reached only 60%," Frank said, "imagine if your weekly factory production operation only 3 days, also a lot of time to do the postprocessing would be very inefficient."

It is predicted that the global 3D printing market will reach $490 billion in 2025. However, if the threshold for post processing does not cross, this prediction is likely to face the risk of premature death.

2. Increase Labor Costs

Grinding and finishing will also consume a lot of manpower, and some jobs still require highly skilled personnel. In the above report, the total wage of 4-10 printers running is about 100 thousand -50 $/ year, and the manpower cost directly after print processing is about $50 thousand / year for each printer.

3. Reduce Employee Productivity Creativity

If employees spend too much time on finishing and polishing these processes, they will reduce the time for innovation. Originally, these hours could be used to develop and speed up production. Recruitment of professional post - processing technicians is also not easy.


4. Quality Is Not Reliable

The advanced approach to 3D printing to make models would have been a horrible sight if you had to use the tools such as art knives, sandpaper and nozzles to do model post-processing.

"The fact is, whatever you put those who support the cutting much good, so will always leave some corner scrap," Marangell said, "this will give parts of accurate geometry original clogging, it is a process of hate."

If the parts are damaged, you have to start all over again and even repeat the process, which wastes more manpower, printing time and materials.


5. Is Harmful to The Environment

In the Grimm survey, a medical device company, Chen Dao, said: "3D print operation is the largest source of hazardous waste in the entire research and development plant".

The SLA model may be immersed in a caustic liquid such as sodium hydroxide. The high risk factor is clearly visible, and inhalation of ABS and PLA material has proved to be very dangerous.

"All of these things, without a single room, dust would be everywhere," Marangell said, pointing to a SLS device.

These costs add up is not a small expenditure, you need to properly dispose of these materials, but also good workers with gloves, clothes and dust respirator, you also need a space to ensure the safe operation of ventilation.

So, after treatment costs are high, time-consuming and harmful to the environment, what should we do?

"Because all 3D printing technologies require post-processing, experienced users will find this very annoying. But it's unwise to give up 3D printing.

"FDM is your easiest 3D print," Frank says. "It's polluting the environment and annoying. You also need gloves and pliers, but eventually you'll find it's the best choice.". If you want a trustworthy FDM 3D Printer can go Alunar 3D Printer Store.

Officially launched next year, Rize One is expected to change this situation, Reebok has indicated that using it can reduce the operation time of 50%.

Rize said that the new technology and the secret formula will help 3D printing technology out of the laboratory and in the office and factory air plant, it is the beginning of this century 2D laser printer commercialized as. Revolutionary.

Not to support the transparent

"You still need a space laboratory, to complete complex postprocessing," Frank said, "but when the design engineer, want to want to make a prototype tool production engineer or doctor to make dental dental cast to have finished. They just buy an 3D printer instead of using a particular lab to print it."

Creative 3D Print Cleaner, Using 3D Printing Technology to Change Life

In the congregation to raise the site Kickstarter, often there will be some very strange gadgets. Although some things are really simple things, they can change our lives. One interesting thing about Kickstarter recently is that it's an innovative 3D print gadget, especially for handheld mixers that allow users to clean things more easily.

Cleaning an egg whisk is not an interesting job. There are always some blind corners that can not be cleaned properly. But this 3D print cleaning brush can change the status quo, easy to remove every corner of the food residue. It is not cleaned or rinsed with water, but is completely cleaned by squeezing it out. Have to say, this must be a kitchen artifact.

According to Zhi Ke 3D understand, this 3D print cleaning brush was invented by Matthew Michel. In fact, this is a very simple concept, but when he realized it with 3D printing, it turned into a creative design. The method is simple. You just need to put the 3D print brush out of the back, start with the holding mixer, and then push out slowly, and the extra food will be completely removed. Not only can the blender be easily cleaned, but it can also be used to the full extent of all the food.

But in fact, this is not a Matthew Michel a person's credit. He also worked with 3D designer Robert Apodaca and engineer Arpita Soni to slowly implement the idea from a small concept into today's creative object. According to them, now 3D printing cleaning brush landing Kickstarter, there is an important gimmick is 3D printing this technology. They have worked with a local 3D printing company to complete print production.

At present, this 3D print cleaning brush has far exceeded the beginning of their congregation raised target $10 thousand, now has reached $50 thousand. The earliest deals are over, but now users can still get a $23 Stainless Steel Blender, and move on!

Does Adidas Want to Make Shoes with 3D Printing?

Popular shoe manufacturer 3D printing technology really is not blowing out, after yesterday released the new 100-lun brand sports shoes sports shoes ms066 3D printing, the well-known sports brand Adidas also today released their new research and development of 3D printing UltraBoost Uncaged Parley sports shoes. It is reported that the shoes used almost all of the materials from the ocean recycled plastic, and then produced using 3D printing technology.

A year ago, Adidas worked with Parley (Parley, an organization that aims to increase awareness of marine pollution and plastic waste), using plastic recycled from the ocean and making 3D sneakers. Obviously, the structure of the experiment is impressive because the shoes combine the ocean recycled plastic and Adidas's 3D print futurecraft bottom. Although the experiment shows that the footwear industry has taken an important step towards sustainability, they are not quite ready to retail it. It is still a concept shoe. But now, Adidas and Parley have decided to release their UltraBoost Uncaged Parley sneakers next month at a retail price of $200. Initially, Adidas will introduce 7000 pairs of sports shoes, but according to the company revealed that the next year, they will launch more than 1 million pairs.

And the new UltraBoost Uncaged Parley sneakers don't seem to add 3D printing components, because 3D printing isn't the ideal method of manufacturing for one million pairs of sneakers. But the sports shoes they make will still be recycled from the ocean, including shoelaces, heels, straps, and laces, all of which are renewable materials. In fact, each pair of shoes contains as many as 11 plastic bottles. According to Adidas officials, most of the UltraBoost Uncaged Parley sneakers are made from coastal areas of Maldives. With the integration of renewable materials Adidas continues to expand, the company even said it hopes to eventually eliminate it from the entire supply chain of plastic, which is a great progress for the company, but also worth mentioning the concept of environmental protection and fashion manufacturing linked as a whole.

The United States Hospital by 3D Printing Technology Development Liposuction Medical Equipment

BioSculpture Technology is working in the Central Hospital of New York and New York Presbyterian affiliated orthopaedic surgeon Robert Cucin company, it is reported that the company recently used 3D printing technology developed a new type of surgical instruments, can be used for the treatment of obesity.

Liposuction, a surgical procedure that removes excess fat from the body's parts, is now used mainly in obese people. According to the American Society for cosmetic and plastic surgery (ASAPS), the number of liposuction operations increased by more than 16% in 2016 compared with 2015.

Dr. ASAPS, President of Jack Fisher, said the increase in liposuction surgery could be attributed to the emergence of innovative technologies such as 3D printing, which have been successful in reducing the risk of liposuction. "Technological advances, smaller surgeries are making these new looking" surgeries "more attractive.". More and more people are starting to invest themselves again. "Dr. Fisher says.

BioSculpture Technology is one of several companies that are currently trying to use 3D printing technology, and the company uses the new technology in order to make patients safer and more effective bariatric surgery. For most surgery, liposuction surgery time, the process and the overall efficiency depends heavily on the quality and ability of surgical instruments. If the surgeon provides specially customized and designed medical equipment, the operation time will be reduced and the risk of operation will be greatly reduced.

The use of 3D printing technology and 3D imaging technology, BioSculpture Technology CEO Robert Cucin, is trying to liposuction physicians make appropriate medical equipment.

Dr. Cucin said, most manufacturers and surgical equipment developers in the development of medical instruments, and did not notice how important human organs precision, because of the internal and external human body organs are quite fine, if the operation of medical equipment can be the perfect adaptation of human body organs, so can to some extent reduce the risk of liposuction surgery.

Though many attempts, also experienced numerous mistakes, Dr. Cucin's team still unremittingly, still trying to optimize the development process and the operation of liposuction medical equipment. Dr. Cucin's goal is to provide customized surgical instruments for each operation phase.

Dr Cucin explained: "many doctors have worked hard to safely extract fat, but over the years they have had little success.". Our goal is to enable 3D printing to improve the safety of surgery." "This particular 3D print device allows us to place it in an extremely small incision that removes fat from the stomach and removes fat hidden under the muscles," he says. You know, in the past, if you want to remove these parts of fat, you can only cut off. So, in general, we're taking fat out safely in an unprecedented way of innovation, bringing people closer to what they want to be."

The ultimate goal of all liposuction operations is to minimize injury to the patient's body and internal structure and safely extract excessive amounts of fat deposits. Therefore, after careful analysis of liposuction, as a target for each muscle, tissue, and body part of the structure, the company is fully guaranteed to extract fat without cutting. Dr Cucin points out that the combination of 3D printing, 3D imaging, and other revolutionary technologies will enable BioSculpture technology and other companies to develop safer devices for patients.

Bariatric surgery, however, has an incredible risk, and the patient will probably have many unexpected complications after the recovery process. NHS is a publicly funded national health care system in the United Kingdom. It points to some common complications of infection, thrombosis, internal bleeding, gastric banding, food intolerance, gallstones, and so on.

Complications such as food intolerance are more psychological than physical. But, BioSculpture says, 3D imaging aids can prevent internal bleeding, infection, and gallstones (in about 20% of people).


Almost every patient had symptoms such as loose skin and gallstones. Skin diseases are usually not easy to treat. Once the disease develops, it is usually a permanent disease, because the space previously filled with excess fat can not be recombined. In most cases, skin complications are mostly caused by an imbalance of fat aspiration.

However, through the 3D printing structure, researchers can predict by mathematical calculation how much excess skin will be produced after extracting a certain amount of fat deposits.

Using 3D printing technology related medical equipment, so that surgeons will be able to patients for safer, more effective liposuction surgery, so beautiful "zero" risk.

How did the American Professor Make Homemade Ceramic 3D Printers at Home?

Ceramic printing has been a hot topic in the 3D printing world, but only a handful of 3D printers can print it. However, the Appalachian State University professor of graphic design TaekyeomLee is to prove to people, you can print DIY ceramics at home. He made a ceramic 3D printer and used it to print exquisite artwork.

As Lee revealed, the project is beyond the scope of academic research, and he wants to explore data modeling and graphic design through 3D printing technology. He hopes to combine print, artwork, ceramics, and 3D printing. He said: "desktop machines have interested me because they don't take up too much space. With this new tool, I can make more complex shapes."

But making a 3D printer isn't easy. About a year ago, Lee purchased accessories for 3D printers and started assembling on an open source file on the internet. Although many difficulties encountered in the air sealing problem, but with a long time of hard work and great patience, he finally developed a set of extrusion system, to be able to 80psi the pressure extrusion clay materials for printing.

After the printer is finished, the treatment of clay material is also a difficult problem. Especially for the grasp of viscosity is very difficult, too dry can not be squeezed out; too soft, printed matter easily collapse. Eventually, he installed 3 small 120mm fans on the print platform, which quickly dried up the prints and prevented them from collapsing. Although not the best method, he is still improving.

According to Suzhou Ke 3D printing understand, Lee is still improving the printer, so that it can print out more complex shapes of objects. With this printer, Lee prints a lot of 3D print, artwork, and fine sculptures. At present, this printer can print clay, clay, ceramics, and even copper, clay and other materials. Of course, the clay material must be sintered to complete the final print after printing.

3D printing technology uses printing personalized tableware

Personalized tableware is now available everywhere, but have you ever used 3D print tableware and personalized tableware?

A study from the Columbia University in the United States said that 3D printing can produce food safety tableware, and enough to change the hotel's service ecology. In their study, all the dishes used in the 3D print dinner were made using 3D printing technology. Making mat with Objet company Connex 500 PolyJet 3D printer, tableware made of stainless steel material 3D printing to meet food safety production; for the first time using 3D printing ceramic tableware, the theme of the feast is Italian dinner, the Venice mask design elements design.

Alunar recommends several versions of the same 3D prints for you.

Although 3D printing is a very advanced technology, there are some designers who somehow connect it with the art of the past. Recently, Czech furniture Lauriger has introduced a new set of tableware series, trying to use 3D printing to recreate the country once glorious cubism.

The concept of customization has become popular, and the advantages of 3D printing technology allow customized concepts to penetrate more into the field of personalized demand. In the past, consumers bought things that were mass-produced, and if they needed personalized things, they would have to find designers to make them. And now, 3D print customization can be used to make ergonomic dishes, and even help people with disabilities.

Watch the American Drama "Pure Genius" Know How to Reveal the Significance of Medical 3D Printing?

For everyone without a medical background, medical treatment is often revolutionary. But Xiao Bian found a hospital theatre where pure genius's highly medical solutions often relied on the recently established medical procedures. In other words, controversial treatment procedures usually come from actual medical breakthroughs already in use by hospitals. This can be fun from some drama series (doctors usually don't feel, but we do). This series of pilot drama on the high-tech medical supplies, reflects the application of 3D printing in the hospital growing on heart model 3D print to solve especially tense situation.

Of course, the average reader will know that the 3D print model can increasingly be found in hospitals around the world, especially for very unusual and highly complex surgeries. In the most extreme cases, what we've seen is this 3D print heart model, which helped save a five day old baby from congenital heart defects. Just two years ago, these types of projects were disposable and rare, but many hospitals are now increasingly systematized in the production of these 3D print surgical models. Through collaboration with the Arizona State University, Phoenix children's hospital through their heart 3D printing laboratory, in fact, regulate the production of these 3D print heart model. The same episode now appears on TV, "pure genius".

The emergence of the 3D print surgical model in the mainstream show really illustrates how far this 3D printing technology is. The series itself was launched last Thursday, and is actually focused on extensive medical solutions driven by these gadgets. The problem is genius James Bell (Augustus Prew), a young billionaire entrepreneur, a rare complication, such as congenital heart defects with free treatment of high-tech revolution.

This is especially true in medical drama, but this 3D print solution has been used regularly at Phoenix children's hospital. In fact, according to statistics from universities and hospitals, there are about two 3D print heart models per week. In general, they provide surgeons with the data needed to plan an operation before entering any patient.

The heart of 3D printing laboratory has actually been developed for a long time, its origin can be traced back to 2010, when the ASU engineering professor David Freixas began recruiting professional art as his image processing laboratory - they can see the possibility of new technology. Justin Ryan is one of them and has been accepted into graduate programs in biomedical engineering. He is now running the Cardiac 3D printing laboratory.

3D printing has now been considered a medical potential, but it doesn't have any use, because 3D print accurate heart models may take weeks, and by then patients may have died. Through the efforts of Ryan and his team, they actually implemented the model in 2012, and with the help of the leadership of the Phoenix children's Hospital, they bought a 3D printer. "A printer in the hospital means we're next door," Ryan said. "The surgeon can look at the image and make several adjustments, and then we can print it once.".

Now, the heart model of patients at Feinikesi children's hospital can print 3D in 9 hours or less, and has produced more than 300. This allows the heart 3D printing laboratory to be the most manufactured surgical model 3D printer in the United States, and they are also manufactured for other local hospitals. Even adult patients benefit from this 3D printing process. In addition to the heart, they are also 3D printing, cancer and so on.

"Not only print, tell the surgeon before the surgery, it helps the child to figure out what the tumor actually looks like," Ryan said. "After the operation, we gave the patient a 3D print of the tumor and let him or her smash it.". Although pure genuis is lagging behind in some respects, the next step in medical 3D printing is not enough. Ryan and his team are also looking for skin cell tests and hope to experiment with liver cells, but they estimate that it may take decades for 3D printing organs to be realistic. But some of them, such as 3D printed heart valves, can be implemented in a year or five. They say 3D print skeletons and other implants, 3D print bones from cancer patients, have also been put on the agenda.

3D Printing Satellite Technology, This is not a Dream or Science Fiction

According to foreign media reports, a group of machine spiders in space orbit spacecraft or 3D printing satellite, this is not a dream or science fiction, but may soon become a reality. The US cable unlimited company, supported by NASA, recently reached a cooperation agreement with the US commercial satellite company Lara space systems, and the two sides will work together on the development of machine spiders. This strange machine spider will be able to use 3D printing technology to directly manufacture parts of space systems in space.

Once the SpiderFab project is successful, there will be a large number of machine spiders busy in space. They can print various giant space system structures and assemble them effectively through 3D printing equipment.

This approach will help us to create extremely large space systems, such as solar arrays and soccer field sized antennas larger than ten times or even hundreds of times larger than today.

The R & D program is called the "SpiderFab" program. According to experts, the first plan to launch a machine to orbit, to test whether it can print parts and assembly of the whole structure, these components include solar panels, antennas, sensors and spacecraft or satellite and other parts etc.. The ultimate goal of the project, however, is more sci-fi. If the research and development is successful, there will be a large number of machine spiders busy in space. They can print huge structures and assemble them effectively through 3D printing equipment. By then, satellites, spacecraft and other equipment will be made directly in space, which will help humans build larger spacecraft or satellites to orbit the earth.

The brains of this "smart spider" are made by the cable unlimited company in Washington, U. S. a.. Cable no limit company and the United States commercial satellite company Lara space systems signed a cooperation agreement, the two sides will be committed to the development of space 3D printing machine spider research and development. Firmamentum, a subsidiary of cable no limit, will test its "Trusselator" technology in the dragonfly program of Lara space systems. The dragonfly project will test the construction of communications satellites on orbit, while the Trusselator technology mainly produces lightweight frame trusses to support solar panels, antennas and sensors.

The Trusselator technology will create high-performance support structures through 3D printing technology and automated assembly technology.

"The dragonfly project provides us with an excellent opportunity to demonstrate space manufacturing technology," said Dr. rob Hoyt, CEO of Firmamentum." Lara space systems CTO Mateo - Dr. Jana said, "the development of next generation communication satellite and space systems will rely mainly on manufacturing technology progress." It is not clear when the trials will be conducted.

The existing satellite to enter the orbit of the earth, when they are in the process through the earth's atmosphere, you must be folded and hidden in the protective cover, to prevent overheating and burned or destroyed by resistance. While making satellite components in space, you only need to compress the machine spiders and raw materials into the rocket and send them into space. As early as 2013, Hoyt had introduced such space manufacturing technology. "The raw materials needed to make these important components in orbit, such as fibers and polymers, can be compressed into a very tight form and packaged into a smaller, cheaper launch medium.". On track, the machine spider manufacturing system will process the raw materials and make a huge structure. This approach will help us to produce antennas or solar arrays that are ten times or even hundreds of times larger than now. These devices will be able to provide greater energy, greater bandwidth, higher resolution, and higher sensitivity for a wider range of space missions."

Another Major Breakthrough in 3D Printing - The Impact of Magnet 3D Printing in Manufacturing

For many of us, the first time we heard about magnets was the science course at elementary school. But as a matter of fact, many of the world we live in is dependent on the forces of mutual restraint and attraction, such as generators, electric horns, trains, cranes......

Recently, the Oak Ridge National Laboratory (ORNL) announced that their permanent magnets would be better than conventional magnets. The permanent magnet itself forms a permanent magnetic field, so it can continue to operate without recharging. The development of this permanent magnet may prove a great success for the development of 3D printing technology. According to ORNL's research, mixing magnetic powders with polymers as binders, and then forming preferred shapes by material deposition, and then using several processing methods to form magnet mixing materials, such as extrusion. At present, the idea of magnet 3D printing is relatively new, and according to the evidence, this technology has been recognized by more and more colleges and universities around the world.

Magnet 3D Printing in Manufacturing

"Manufacturing is changing rapidly. A customer may need as many as 50 different designs, so this universal magnet will be a good solution."." Liang Li ORNL researchers said, "the traditional process of injection mold requires a fee in the design to create a mold, but 3D printing technology, it can quickly complete the design through the computer aided design function". The composite particles are formed by mixing 65% of the isotropic NdFeB magnetic powder with 35% of the polyamide (nylon). The production company then molded the composite particles into a variety of shapes by dissolving and pressing them. Nylon is a very common and widely used laser sintering 3D printing material. After such a mixing method, it becomes a permanent magnet mixture suitable for 3D printing. It is proved that the extruded nylon magnet composite particles can exhibit higher accuracy than other materials such as plastic filament.

3D printer using BAAM system itself has a huge amount of construction, with 3.56*1.65*0.86 meters of molding space, and has a single screw extruder, print bed and hot bed. Therefore, the utility model can directly stack the printing pieces on an aluminum board at the printing temperature of 270 DEG C, and can provide maximum adhesive force. In addition, this innovative method of manufacturing permanent magnets can effectively reduce the waste of 30% to 50% of the waste generated during the 3D printing process. The reason is simple, because in the process, any material can be obtained and recycled. Considering that NdFeB magnetic powder is the most permanent magnetic material so far, it will be a big surprise for 3D printing material. Due to the addition of permanent magnetic material, printing complex shapes of motors and engines will become a less difficult task. Because it eliminates many of the limitations of today's manufacturing methods." Alex King, head of materials research institute.

For the moment, the research is still new, so further research and exploration is still needed in the laboratory. But the team's work has laid the foundation for its future success and provides enormous potential for the use of magnetic Science in consumer goods. I believe we will also be the same as Xiao Bian thought, if 3D printing technology can really bring us more powerful and more flexible products, then its development will be overwhelming. The permanent magnetic material developed by ORNL is undoubtedly an important material to change the world.

3D printing a house within 24 hours, Do you believe it?

Hi, gays, this print house is said to be not the children's model house, but can live in the house Yes, you're not wrong, it is now not the future prospect of 3D technology, what happened? Please listen to me speak slowly below:

Cazza Construction, a construction company in San Francisco, has been a millionaire entrepreneur since he was CEO at the age of 19. He is Chris Kelsey. He recently announced that they could print an entire 100 square meter house within 24 hours of 3D!

Chris was a high school dropout, but his feat was definitely more than most of his peers could do. He is not only a dutiful child, not a boy addicted to online games, Chris is Cazza Construction CEO, is a millionaire, but the company is getting more and more attention, whether in additive manufacturing or in construction field are quite valuable.

Even more surprising is that this is not the first time the Chris 3D printing company business to try, when he was 17 years old when he was appointed Cazza, has been a software development company called Appstitude, was a India entrepreneur and investor Deepansh Jain bought. He then created Cazza with the money acquired, a company that is likely to change the world's output.

A 3D printer that prints a house sounds incredible. A very important factor is that they use printers that print large buildings instead of printing many small parts and then stitching them together. It also reduces pollution and costs.

But the company is keeping a tight picture of its technology and is not expected to be announced until December. Now, Cazza is busy with many other companies, especially in the Middle East and Asia, such as Dubai and china. Dubai hopes to achieve 3D printing houses by 2030, while China is the cradle of 3D printing technology, which is beneficial to the development of Cazza.

"We're not just using this technology for printing houses, but for large buildings, too. We plan to release this technology in December and release the technology for printing large buildings in 2017. A year from now, we will show more and more of our skills." De Los Rios says.

While many people are excited by the news, there are also many people who are skeptical. When printing a mixture of dirt, Cazza says, only one person needs to add steel to the side. Chris has acknowledged the confirmation, but he hopes to convince partners to use their technology because the technology can cost as much as 90%.

In addition to being a 3D printing company, Cazaa is now working on machines that automatically install pipes and power systems, making construction more efficient. This technology will undoubtedly result in extensive layoffs, and Cazza needs to help them find the right way to do it when they work with their partners.

Using 3d printing neural scaffold for a new generation of nerve therapy

According to a new study,3d printing may act as a powerful tool in neural tissue engineering.Degenerative disease is a major cause of nerve injury or trauma.Nerve regeneration, and also is the regeneration of the nervous tissue, cell or cell products or repair,Can help repair the damage.However, the repair of large area damage is a very challenging task.

3d printing neural scaffold

At George Washington university scientists have discovered that a 3 d print nerve scaffold with low energy laser therapy (LLLT) on their will "create a new strategy to repair nerve degeneration".

The researchers modified a SLA 3 d printers
According to the study, 3 d printing is a very attractive for tissue regeneration choice, because it can control the placement of functional components from the space, to produce a complex 3 d scaffolds.This process provides a design feasibility for specific patients, make the researchers for a specific injury custom 3 d printing implants, which further increased the probability of a full recovery.

In addition, compared with the traditional support methods, 3 d biological effect of printing is a better way, because "by adjusting the computer aided design and print materials formula, it can produce a controlled porosity and mechanical properties".

In preparation for the nerve scaffolds, the researchers in the past week platform developed on the basis of a 3 d printer based on stereo lithography.An important modification on the printer is added a 110 mu m optical fiber coupling, it USES a solid source of ultraviolet laser (355 nm).By using the custom 3 d printer, a "natural GelMA and synthetic PEDGA combination" be printed into the required shape.

Enhanced cell proliferation after low light stimulation

3 d printing nerve scaffolds were planted neural stem cells (NSCs), and every other day for 15 seconds of low illumination.Compared with those without LLLT in the control group, after light of cell proliferation rate was 44.4% higher.According to the research team, the success of the study "may be paved the way for the development of new generation nerve treatment".
The study has been published in the International Society for Biofabrication "magazine.

3D printing industry development trend analysis

Short-term trends

1) 3D printing services and impact model of innovation

3D printing industry chain involves many links, including 3D printing equipment manufacturers, the 3D model software suppliers, 3D printing service providers and suppliers of 3D printing materials.So the chain around the 3D printing will create many opportunities.In 3D printing industry chain, in addition to appear big brand manufacturers, is also likely to be based on 3D printing services giant.The following two example of 3D printing service innovation.

Shapeways companies do not sell direct printer, but "the whole value chain" to move through the social network to the line.Users in the site after registration, can put their own product design uploaded to the site, can also purchase the existing 3D design, selection and purchase of raw materials, you can place the order, the company will be printed finished product delivery.In addition, users also can display and sell their products online, and to sell products to others.At present the company has nearly 150000 member platform, more than 6000 designers, June 20, 2012, has for more than 100 3D printing products, is one of the most popular jewelry, iPhone cover and the toy train.

2) 3D printing industry faces many challenges

3D printing technology in China is currently facing many challenges, generally at the primary stage of the industrialization of emerging technology, mainly displays in: one is the scale of the industry level is not high.3D printing is mostly stay in the laboratory of universities and research institutes, enterprises scale is generally small.The second is technology innovation system is not sound.Innovation resources relative to split, standard, test, research and development such as the lack of public service platform, has not yet been established production, with combination of technical innovation system.Three is industry policy system is not yet perfect.A lack of forward-looking, consistency, systemic industrial policy system, including development planning and fiscal and taxation support policy, etc.Four is to strengthen industry management;Five is in urgent need of strengthening education and training system.

Medium-term development trend

In the medium term, complementary with the traditional manufacturing technology.Compared with the traditional mode of production, 3D printing is a significant change, but at the moment and JinZhongQi also don't have the ability to promote the third industrial revolution, also won't be the terminator of traditional manufacturing.The current 3D printing technology in complex components, new product development, and implementation of collaborative manufacturing to more creative advantage, the application of the ideal is in the field of personalized or customized.Therefore, JinZhongQi still can't completely replace the traditional manufacturing technology, should be complementary advantages.

Although 3D printing may revive some developed country manufacturing industry competitiveness, but in the short term is difficult to overturn the traditional manufacturing mode.Reason has 3: it is a 3D printing is a new precision technology and information technology integration, compared to the machine production, not substitute, but parallel and complementary relationship;Second, the 3D printing limited categories of raw materials, decided to print out the vast majority of products;Three highly personalized printing costs, it is difficult to realize the traditional manufacturing mode of mass, low-cost manufacturing.

Long-term trend

Synthesis of 3D printing industry characteristics and current situation of the development of technology, we believe that the future trend of the industry development is the following features:

1) 3D printing personal consumption of strong growth

With the rise of "personal" made in the field of personal consumption, 3D printing industry still is expected to maintain a relatively high growth.Help to pull the personal use of desktop 3D printing equipment requirements;It will also promote the upstream print materials (mainly photosensitive resin and plastic) consumption.

2) 3D printing application degree deepening metal materials

In the field of industrial consumption, due to the continuous development of 3D printing metal materials, as well as the metal itself is widely used in industrial manufacturing.Foresight is expected, primarily in the laser sintering metal molding technology of 3D printing equipment, will be in the future in the field of industrial applications, for the development of relatively quickly.Short or medium term, the application of this field is still concentrated in the product design and manufacturing tools.

3) the division of professional industrial chain will be further deepened

At present, the main 3D printing enterprise general with material supply, equipment manufacture and print services integrated form.This is the industry technology popularization and the limit of the size of the market in the initial period of development.In the long term, the industrial chain of each link can produce professional separation: can appear material suppliers and professional printing enterprise, product design service will be independent or transfer to the downstream consumption enterprises.3D printing is expected to be converted into a real tool platform.

What is 3d printer？

3D Printer and Works

3d Printers (3d Printers) is a named Enrico Denny (Enrico Dini) inventors designed a magical printer, it can even be "print" a complete building.3 d printing has become a trend, and is widely used in the field of design, industrial design, in particular, digital products mould etc., can be in a few hours to finish a mold to print, save a lot of products to the market development time.

3d printer can print 3d model with a variety of raw materials, using 3d cad software, engineers to design a model or prototype, whether the design is a house or artificial heart valve, through the related company after production of 3d printer for printing, printing materials can be organic or inorganic materials, such as rubber, plastic, and even human organs, different printer manufacturers provide print material differs character.
