Printer combining direct writing type printing and hot melting deposition type printing and printing method

Abstract

The invention discloses a printer combining direct writing type printing and hot melting deposition type printing and a printing method. The printer comprises a hot melting deposition printing head, adirect writing printing head, a printing head fixture, an X-axis displacement table, a Y-axis displacement table, a Z-axis displacement table and a cube printer frame. The printing method comprises the following steps: 1) slicing and layering a 3D model by utilizing slicing software and obtaining position information and material information of each layer, and storing the material information inmodel data corresponding to slicing information in the form of extrusion head codes; commanding the X-axis displacement table, the Y-axis displacement table and the Z-axis displacement table to move by utilizing a motion path containing material information codes, and moving the corresponding printing head based on the material information to a corresponding position; and 3) based on model slicesand the material information, required quantitative printing material is extruded out through the direct writing printing head or the hot melting printing head, so as to achieve direct writing type and hot melting deposition type combined 3D printing. The printer combining direct writing type printing and hot melting deposition type printing and the printing method disclosed by the invention can achieve simultaneous printing of a plurality of materials.

Description

technical field [0001] The invention belongs to the field of additive manufacturing, and in particular relates to a printer and a printing method combining direct-write printing (DIW) and fusion deposition printing (FDM). Background technique [0002] In recent years, with the development of additive manufacturing technology, 3D printing technology has achieved great success in the manufacture of metals, ceramics, and polymers. However, traditional 3D printing technology is limited to the printing of a single material, and the printing of composite materials has become a 3D printing technology. Trends in printing technology law exhibition. [0003] The FDM thermal fusion deposition 3D printing technology is to feed the thermoplastic wire into the extrusion nozzle, and the thermal fuse accumulates the structural parts according to the action path preset by the printing software. However, the FDM printing method is limited to limited thermoplastic printing filaments, such as ...
