Abstract

The invention provides a multi-component 3D printing extruded material, made by mixing N components, with N>/=2; the N components include refractory material powder, a dispersant and water; at least one of the N components also include a thickening time control agent; any m ones of the N components also include a binder; at least one of the rest N-m components also include a curing agent. The multi-component 3D printing extruded material has the advantages that shelf life of the material can be extended and serial products having different curing times or different temperature conditional applications can be provided.

Description

technical field [0001] The invention belongs to the technical field of 3D printing materials, and in particular relates to a multi-component 3D printing extrusion molding material. Background technique [0002] Rapid prototyping, also known as additive manufacturing, is based on the digital stereo technology of computers and the Internet. It converts a design item into a 3D digital model, and then adopts layered processing and superposition forming, that is, by adding materials layer by layer. Printing into a 3D entity, thereby turning the blueprint on the computer into a physical object, is far superior to traditional manufacturing techniques in terms of cost, speed and accuracy, and is especially suitable for personalized customization. [0003] The 3D printing molding technology of refractory materials includes laser selective sintering molding technology, light curing rapid prototyping technology, melting deposition molding technology, free extrusion molding technology, ...
