Polyamide particles, many of which are non-spherical shape of low melting point polyamides (polyamide 12), are used as lubricants in cosmetics and as materials in powder-based 3D printing. In order to create high-quality 3D printed objects, truly spherical particles with outstanding fluidity and uniform fillability would be ideal. Especially, polyamide particles of high melting points would be vital for practical parts in view of their high strength and heat resistance. The drawback with conventional production techniques, however, has been the difficulty of creating truly spherical polyamide particles with the high melting points that needs handle with high-temperature conditions.
