Abstract

The invention relates to a 3D printing device, in particular to a 3D printing device for controllable distribution of materials in an extrusion line and a control method of the 3D printing device, and aims to solve the problem that accurate, flexible and controllable adjustment of spatial distribution of multiple materials in the extrusion line is difficult to realize by an existing extrusion type 3D printing technology. In order to achieve the purpose, the 3D printing device with the controllable distribution of the materials in the extruded lines comprises a mixing channel, a main body material feeding assembly, an embedded material feeding assembly and a moving deposition assembly. The control method of the 3D printing device for controllable distribution of the internal materials of the extrusion lines comprises the following steps that a main body material and an embedded material are prepared; extrusion molding of the printing material; and performing corresponding post-processing on the printed structure. According to the scheme, the mixing cavity is formed in the mixing channel, and the main body material feeding assembly and the embedded material feeding assembly are arranged, so that the main body material and the embedded material can be cooperatively conveyed and compounded in the same mixing space.
