Material melting device of color 3D printer

Abstract

The invention discloses a material melting device of a color 3D printer. The material melting device comprises a support, a thermister, a thermocouple, a heating pipe and a conical spray nozzle, wherein the frontage surface of the support is provided with a first fixing hole and a first through hole; the side surface of the support is provided with an installation hole, a second fixing hole and a second through hole; the first fixing hole and the second through hole are intersected; the installation hole and the second fixing hole are both intersected with the first through hole; the heating pipe is installed in the first through hole, passes through the first through hole and is connected with the conical spray nozzle in a threaded mode; the installation hole is connected with a conductive stud which is communicated to the heating pipe by internal threads; the thermister is connected to the conductive stud; a first bolt, which is screwed into the first fixing hole, of the thermister, is fixed in the second through hole; a second bolt, which is screwed into the second fixing hole, of the heating pipe is fixed in the first through hole. The material melting device is simple in structure, is stable in heating, can be controlled, is good in operation flexibility, and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of 3D printer structures, and in particular relates to a 3D printer material melting device capable of heating, melting and ejecting printing materials. Background technique [0002] 3D printing technology has been developed for more than 20 years. Since the early 1990s, domestic and international industries started almost simultaneously. In 2012, this technology received widespread attention at home and abroad, more from an article in the British "The Economist" magazine, which regarded 3D printing technology as one of the major symbols of the "third industrial revolution". The application object of 3D printer can be any industry, as long as these industries need models and prototypes. Israel's Objet believes that industries with high demand for 3D printers include government, aerospace and defense, medical equipment, high technology, education, and manufacturing. Most of the existing 3D printer material melting de...

AI Technical Summary

Problems solved by technology

Most of the existing 3D printer material melting devices have defects such as complex equipment structure, poor uniformity and stability of the molten product, and inability to provide pressure power for the molten material ejected from the nozzle of the printer.
