3D printer nozzle

Abstract

The invention discloses a 3D printer nozzle. The 3D printer nozzle comprises a nozzle body and a heating assembly, wherein the nozzle body comprises a first mounting part, a first mounting plate, a second mounting part and a nozzle part; the heating assembly comprises a heating device, a second mounting plate and a third mounting part; cooling fins are arranged in a second mounting groove on the third mounting part; one end of the third mounting part is connected with the second mounting plate; the second mounting plate is provided with a mounting bin; a heating device is arranged in a first mounting groove formed in the inner wall of the mounting bin; the first mounting part, the first mounting plate, the second mounting part and the nozzle part are sequentially connected; a first hollowbin on the first mounting part, a first through hole on the first mounting plate, a second hollow bin on the second mounting part and a second through hole of the nozzle part sequentially communicate;a groove is formed in the outer wall of the second mounting part; the second mounting part is arranged in the mounting bin; and the second mounting plate is connected with the first mounting plate. The 3D printer nozzle is convenient to disassemble from and assemble with the heating assembly, and is capable of heating raw materials in the nozzle sufficiently and uniformly.

Description

technical field [0001] The invention relates to the technical field of printer nozzles, in particular to a 3D printer nozzle. Background technique [0002] 3D printing technology is a type of rapid prototyping manufacturing technology that has developed rapidly in recent years. It is based on computer technology, through software layered discrete and numerical control molding systems, using high-energy laser beams, hot-melt nozzles, etc. to process metals, ceramic powders, plastics, etc. The manufacturing method of layer-by-layer accumulation and bonding of materials such as cell tissue and cell tissue. The nozzle is an important part of the 3D printer; when the nozzle is in use, it needs to heat and melt the filament; but the printing material inside the nozzle structure has a certain thickness, so there are often insufficient heating of the printing material during the heating process phenomenon, resulting in poor quality of the printed product; and now that the nozzle is...

Problems solved by technology

The nozzle is an important part of the 3D printer; when the nozzle is in use, it needs to heat and melt the filament; but the printing material inside the nozzle structure has a certain thickness, so there are often insufficient heating of the printing material during the heating process phenomenon, resulting in poor quality of printed products; and now after the nozzle is damaged, it is time-consuming and laborious to disassemble the heating device and nozzle, and replace the nozzle, which greatly reduces production efficiency
