Abstract

The invention discloses a porous ceramic microsphere composite material for 3D printing. The porous ceramic microsphere composite material is mainly composed of porous ceramic microspheres and thermoplastic resin, wherein the porous ceramic microspheres account for 80-99% of total weight, and the thermoplastic resin accounts for 1-20% of the total weight. The raw materials undergo extrusion pelletization through a twin-screw extruder so as to prepare the ceramic material for 3D printing. By characteristics of good fluidity and low density of the porous ceramic microspheres and by combination of thermoplastic processability of the thermoplastic resin, the characteristic of low thermoplastic processability of the ceramic material is overcome, and more selections are provided for a 3D printing material. The invention also discloses a preparation method of the ceramic material. More printing material selection spaces are provided for a three-dimensional printing technology, and a three-dimensional structured product of the ceramic material is prepared by a fused deposition modeling 3D printing technology. The production technology is simple, low-cost, safe and environmentally friendly, and has a market application prospect.

Description

Technical field [0001] The invention belongs to the field of 3D printing manufacturing, and specifically relates to a ceramic material used for 3D printing and a manufacturing method thereof. Background technique [0002] The global industry is undergoing the third industrial revolution. Unlike the past, this revolution will also have a huge impact on the development of the manufacturing industry. One of the most important new technologies is rapid prototyping technology, that is, 3D printing technology. Today's 3D technology mainly refers to the digital three-dimensional technology based on computers and the Internet. It is a rapid prototyping device that uses technologies such as light curing and paper lamination to turn the blueprint on the computer into a real object. It is far from cost, speed and accuracy. Better than traditional manufacturing technology, its working principle is to convert a design item into 3D data, and then use layered processing and superimposition form...
