Method of manufacturing ceramic matrix composites reinforced with metallic particles

A method for manufacturing an article comprising ceramic matrix composites reinforced with metallic particles, comprising:

• a) producing a mixture by mixing a solvent in an amount of 2-15 parts by weight with two organic monomers in an amount of 2-15 parts by weight each, and with a photoinitiator in an amount of 1-5 parts by weight based on the sum of the weights of organic monomers, wherein the photoinitiator is selected from a group comprising:
• a mixture of ethyl (2,4,6-trimethylbenzoyl)phenylphosphinate and bis-(2,4,6-trimethylbenzoyl)phenylphosphine oxide, bis-(2,4,6-trimethylbenzoyl)phenylphosphine oxide, and ethyl (2,4,6-trimethylbenzoyl)phenylphosphinate;
• b) producing a further mixture by adding to and mixing with the mixture produced in (a) a dispersing agent in an amount of 0.2-5.0 parts by weight, a ceramic powder in an amount of 65-90 parts by weight, and a metal powder in an amount of 0.1-10.0 parts by weight wherein the dispersing agent is selected from a group comprising a polyester and polyamine copolymer as a 50% solution in a trichlorethylene-ethanol azeotrope, and a polyester and polyamine copolymer as a 50% solution in 2-butanone;
• c) mixing and deaerating the further mixture produced in (b);
• d) using the deaerated further mixture produced in (c) in a 3D stereolithographic printer to form a product item in accordance with a previously prepared product design;
• e) sintering the product item formed in (d), whereby the article results.
