Abstract

The invention designs a color-mixing printing spray-head, and provides a color-mixing printing scheme of a 3D printer single spray-head. The color-mixing spray-head is a three-in-one-out printing spray-head. Materials with different colors are supplied by three feeding pipes correspondingly, and melt and are mixed in a three-level mixing chamber under the influence of a heating pipe, and all kinds of different colors can be modulated according to the principle of three-primary colors of raw materials. The spray-head communicates with the three-level mixing chamber, and raw material fluid mixed evenly is extruded from the spray-head under the influence of the pressure of an extruder. According to the color-mixing 3D printer spray-head and the printing method, the problem that an existing single spray-head can only print one kind of color is solved, and any mixed colors can be printed theoretically.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a color-mixing 3D printer nozzle and a printing method. Background technique [0002] There are two definitions of 3D printing, narrowly refers to "the powder-based manufacturing technology developed by MIT". In a broad sense, it refers to all additive manufacturing technologies (Additive Manufacturing). At present, the printing principles of 3D printers mainly include the following categories: [0003] 1. Based on polymer polymerization reaction as the basic principle: Stereolithography (SLA), Polymer Jetting, Digital Lighting Processing, Micro Stereolithography. [0004] 2. Based on sintering and melting as the basic principle: Selective Laser Sintering (Selective Laser Sintering, SLS), Selective Laser Melting (SLM), Electron Beam Melting (EBM), Fused Deposition Modeling Technology (Fused Deposition Modeling, FDM). [0005] 3. The basic principle of powder-adhesive: thr...
