Abstract

The invention discloses a toughened ceramic-based material for 3D printing and a preparation method of the toughened ceramic-based material. The toughened ceramic-based material comprises the following raw materials in parts by weight: 40-50 parts of kaolin, 10-15 parts of quartz, 12-20 parts of aluminum oxide, 5-10 parts of zirconium oxide, 6-12 parts of titanium dioxide, 9-15 parts of silicon oxide, 8-15 parts of acrylic resin, 2-5 parts of a dispersing agent, 0.5-1 part of an interface modifier, 0.1-0.5 part of a binder, 4-8 parts of metal fibers and 1-3 parts of sodium hydroxymethyl sulfonate. The invention further discloses a preparation method of the toughened ceramic matrix for 3D printing. The metal fibers and the sodium hydroxymethyl sulfonate are added into the formula of the ceramic at the same time, so that the problem that the toughness of the ceramic manufactured through 3D printing is poor is solved through the synergistic effect of the metal fibers and the sodium hydroxymethyl sulfonate.

Description

technical field [0001] The invention relates to the technical field of 3D printing ceramics, in particular to a toughened ceramic base material for 3D printing and a preparation method thereof. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology, also known as additive manufacturing. It is based on digital model files, using powdered metal or plastic and other bondable materials to construct by layer-by-layer printing. object technology. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems,...
