Novel color 3D printer

Abstract

The invention relates to a novel color 3D printer, comprising a printer base, vertical supports arranged on the two sides of the base, a controller arranged on one side of the base, a transverse rod arranged at the upper ends of the supports and capable of horizontally moving front and back relative to the supports, and a spray head base arranged on the transverse rod and capable of horizontally moving relative to the length direction of the transverse rod. A printing platform is arranged on the base; a main spray head and an auxiliary spray head are fixedly arranged on the spray head base; a mixing unit is arranged at the feeding port end of the main spray head, and is connected with an RGB three-color feeding barrel and a first resin feeding barrel; the auxiliary spray head is connected with a second resin feeding barrel; resin in the first resin feeding barrel is thermosetting resin; and resin in the second resin feeding barrel is thermoplastic resin. According to the novel color 3D printer, the color mixing proportion of the RGB three-color feeding barrel is controlled through a switch, so that resin with the needed color can be obtained; and the thermoplastic resin sprayed by the auxiliary spray head serves as a removable supporting material, so that printing forming of an embedded non-supporting structure can be implemented.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a novel color 3D printer. Background technique [0002] 3D printing is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing, 3D printing is used in jewelry, footwear, industrial design, architecture, dentistry It has been applied in the medical industry and other fields, and has the advantages of short development cycle, low production cost, and high production efficiency; most of the existing 3D printing is monochrome printing, and 3D printers can only print products with raw material colors, and a few color 3D printers require The raw materials are dyed first, and then mixed with raw materials of different colors, the color mixing effect is poor; moreover, 3D printers cannot print internal unsupported embedded structures, so products with complex nested structures cannot be produced.
