Independent dual-nozzle 3D printer

Abstract

The invention discloses an independent dual-nozzle 3D printer, which comprises a support, an independent nozzle device 1, an independent nozzle device 2 and a track. A movable support plate is mountedon a base plate of the support, a moulding platform is welded and fixed above the support plate, one sides of the vertical rods far from the central position of the independent dual-nozzle 3D printeron both sides of the support are both welded and fixed with fixation blocks, a fixed plate are connected between the two fixation blocks, the track is disposed at the central position of the fixed plate, the vertical rods at both sides of the support are fixedly equipped with the independent nozzle device 1 and the independent nozzle device 2 respectively, the independent nozzle device 1 consistsof a stepping motor 1, a material guide pipe 1 and a printing nozzle 1, the stepping motor 1 is fixed on the front end surface of a fixation block on one side of the support through a threaded screw,the output shaft of the stepping motor 1 is fixedly connected to a belt pulley through a bond, the belt pulley is equipped with a belt 1, and the other end of the belt 1 is connected to a belt pulleyat the front end surface of the fixation block on the other side of the support.

Description

Technical field [0001] The invention relates to the technical field of printers, in particular to an independent dual-jet 3D printer. Background technique [0002] In recent years, 3D printing technology has developed vigorously and social attention has increased sharply. 3D printing technology has been widely used in national defense and military industry, aerospace, marine and automotive industries, in the construction industry, medical and health, doll toys, clothing and clothing, food Civilian-level industries such as processing have just started. 3D printing technology, the popular point is rapid prototyping technology. At present, the more mature 3D printing technologies mainly include: SLA technology, F3DM technology, SLS technology, LOM technology, 3DP technology and PCM technology, etc. F3DM technology is based on the principle of fused deposition. It melts filamentous hot-melt materials and extrudes them through a nozzle with a fine nozzle. The hot melt material is mel...

Problems solved by technology

After the hot melt material is melted, it is ejected from the nozzle, deposited on the panel or the previous layer of solidified material, and starts to solidify after the temperature is lower than the solidification temperature, and the final product is formed through the accumulation of layers of materials, using F3DM technology. It is the F3DM 3D printer. All the F3DM 3D printers currently on the market are single-head printing, which can only print one color, or only one print head works at the same time, so it can only print monochrome models. The forming accuracy is low and the printing speed is slow. Smart The level of modernization is low, so it is only necessary to study a 3D printer that can realize various printing
