Abstract

The invention discloses a direct-writing multi-material composite 3D printing system and method, including: a 3D printing module for manufacturing multi-material composite products; a material supply system for real-time supply of different materials in different proportions; an air pump system for The power supply in the material supply process; the computer control system controls the orderly cooperation of each system through the control software, and realizes the completion of multi-material composite printing products according to the established process. The invention can realize composite printing and forming of multi-materials with arbitrary geometric cross-sections in a single channel in direct-writing printing. In addition, the controllable variable-diameter rotary forming shaft proposed by the present invention can dynamically adjust the diameter of each section of the forming shaft according to the pre-design, thereby realizing efficient three-dimensional forming of unsupported symmetrical structures, which has great application potential in the fields of biomedicine and engineering.

Description

technical field [0001] The invention relates to the technical field of multi-material additive manufacturing, in particular to a direct-writing multi-material composite 3D printing system and method. Background technique [0002] Direct writing 3D printing technology is a kind of printing ink (or slurry) with certain rheological properties and shape retention ability loaded into the syringe, and then installed on a movable three-dimensional platform, controlled by computer according to the preset It runs on a predetermined trajectory, and at the same time, the printing ink is deposited on the forming platform through the feeding system. According to the curing method of the printing ink, different curing processes (such as solvent volatilization, UV light, etc.) can be selected to cure the ink. Print layer by layer to form three-dimensional components. Its low energy consumption, low cost, and strong universality have attracted a lot of attention, and it is currently widel...
