Toray Industries, Inc. has devised a technique that makes it simple to produce micro-level spherical particles of polyamide (PA 6 and 66) having high melting points.

 .

It has been difficult to date to achieve true spheroidization with these synthetic polymers. This new technique could revolutionize 3D printing by enabling the production of practical parts that are high strength and heat-resistant according to Toray.

Spherical polyamide 6 particles for 3D printing. PA 12 powders, many of which are non-spherical in shape and exhibit low melting points, are used as 3D printing materials. In order to create high-quality 3D printed objects, truly spherical particles with outstanding fluidity and uniform fillability would be ideal. PA particles with high melting points are vital for practical parts in view of their high strength and heat resistance. The drawback of conventional production techniques, however, has been the difficulty of creating truly spherical polyamide particles with […]
