Document Type and Number:
WIPO Patent Application WO/2019/205508
Kind Code:
A1
Abstract:
Disclosed is a three-dimensional printing method for instantly generating a needed molten raw material by means of a resistance heating function during three-dimensional printing. The method can realize three-dimensional printing of material having a high melting point and falls within the technical field of additive manufacturing. The method is characterized by applying a current between a solid raw material and a body to be printed; partially or fully heating the solid raw material located between a guide apparatus and said body to be printed into a molten state by means of resistance heating; and generating a molten raw material in a space located between the guide apparatus and the body to be printed. During the accumulation of the molten raw material, an area of the body to be printed and where the molten raw material is to be accumulated and/or is being accumulated is heated; or, the body to be printed is heated; or, the area of the body to be printed and where the molten raw material is to be accumulated and/or is being accumulated is heated, and the body to be printed is heated.
