Document Type and Number:
WIPO Patent Application WO/2023/125367
Kind Code:
A1
Abstract:
A 3D printing wire, a method for preparing a 3D printing wire, a 3D printing method, and a 3D printing apparatus. A core-shell structured 3D printing wire 10 is formed by co-extruding a first-polymer-based composite material 100, and a second-polymer-based composite material 111,. In the core-shell structured 3D printing wire 10, a shell structure formed by the second-polymer-based composite material 111, wraps a core structure formed by the first-polymer-based composite material 100,, wherein the volume fraction of a filling material in the first-polymer-based composite material 100, is greater than the volume fraction of a filling material in the second-polymer-based composite material 111,; moreover, the material of the shell structure contains a non-filled polymer material with a composite filling amount of zero.
