The invention discloses a sprayer of a 3D printer. The sprayer comprises three feeding mechanisms and a mixing mechanism, wherein each feeding mechanism comprises three feeding funnels, three feeding pipes, heating devices, output pipes and weighing hoppers; the three feeding pipes are arranged below the three feeding funnels; one heating device, one output pipe and one weighing hopper are arranged below each feeding pipe; temperature sensors are arranged on the surfaces of the heating devices; valves are arranged below the weighing hoppers; the mixing mechanism comprises a mixing hoper and a nozzle; the mixing hoper is arranged below the three feeding mechanisms; a thermal insulation layer is arranged on the outer surface of the mixing hopper; a valve controller is arranged on the right side of the upper end of the mixing hopper; a stirrer for stirring fused printing material is arranged in the mixing hopper; and the nozzle is arranged at the lower end of the mixing hopper. The sprayer of the 3D printer can carry out colorful 3D printing with material silks of three primary colors mixed according to any ratio, and colorful printing can be realized without switching over the sprayer, so that the color of a 3D printed product is richer.
Description
technical field [0001] The invention relates to the field of 3D printers, in particular to a spray head of a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive material to create three-dimensional objects. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. Existing 3D printers generally can only print products of a single color, and the color of the printed product depends on the color of the supplied material, so color products cannot be printed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a spray head of a 3D printer...
