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.

Development trend and practical application of high performance 3D printing photosensitive resin

The day before, the well-known light curing desktop 3D printer manufacturer Formlabs company released the launch of a series of newly developed 3D printing photosensitive resin, these materials can make your Form 2 Desktop 3D printer to get more power in terms of rapid prototyping and mold.

These new resins can simulate a whole range of injection molded plastics without the weakness of these materials. So if you are looking for a ABS like easy to use plastic prototype, or can durable resin concept you polypropylene products, or in just a few minutes to create the function mold of heat resistant resin, even for new tires and the prototype rubber flexible resin, Formlabs company it can provide corresponding products for you.




Of course, these products are for those who have the 3D print for professional users of rapid prototyping, such as design and engineering consultants, but ordinary lovers or guests can also design their own want to achieve with it.

It is reported that, Formlabs company was founded in 2011, specializing in the production of commercial SLA 3D printer, its products can be used in product design, dentistry, medical model manufacturing, including many fields. The resin products are aimed at the Formlabs company SLA 3D printer development, which means that designers can before you can print products simply can not use it, and according to the different materials show their own appearance. According to the company, prototypes printed with these resins can be used for basic testing and verification.



So if you want to make a product of ABS material, you can use its reformulated Tough Resin and complete your conceptualization and prototyping on your desktop with your Form 2 SLA 3D printer. This engineering resin creates a balance between strength and elongation so that it is sufficiently strong under pressure and has better impact resistance than other plastic products.

In addition, they are also resistant to deformation, so if you need absolute precision or make prototypes that require a precise combination of components, this Tough Resin is the ideal choice. And its strength is high enough to make fastener joints.

Another Durable Resin resin products, it can be used to simulate the polypropylene, the latter is a relatively common material, relatively wide range of applications, can be made from all the products with a flexible locking hinge to the bumper of the car, and has very good gloss.

As for its high temperature resistant High, Temp, Resin, at 0.45 MPa, the deformation temperature can reach 289 degrees celsius. So if you need to make a thermoset mold, that might be the answer you've been looking for.
