3D printing powder compositions and methods of use

摘要

Powder compositions that can be used with traditional 3D printing technology and methods for producing 3D printed building materials that have comparable compressive strength to standard concrete and tensile strength up to 70% greater than standard concrete.

主权项

1. A method of producing a product using 3D printing, comprising:
(a) preparing a powder composition comprising:
(i) approximately 0.75 to approximately 2.0 parts by weight of an adhesive material;(ii) approximately zero to approximately 2.0 parts by weight of an absorbent material; and(iii) approximately 4.0 to approximately 6.0 parts by weight of a base material; (b) introducing said composition into a 3D printer and producing a part with successive applications of powder and a binder; and (c) infiltrating the part with a post-processing material selected from the group of materials consisting of: resin, epoxy resin, epoxy resin 7132, acrylic resin, silicone, and fiber reinforced plastic (frp).
