Spray head structure for three-dimensional printing

Abstract

The invention provides a spray head structure for three-dimensional printing, belongs to the technical field of three-dimensional printing, and solves the problem that printing is not smooth due to incapability of controlling printing temperature. The spray head structure for three-dimensional printing comprises a fixed seat, a first through hole is formed in the surface of the fixed seat in an axial direction, a nozzle is made of high-precision alloy, one end of the nozzle is connected with one end of the through hole, a heater is connected to the position, close to the other end of the nozzle, of the nozzle, the spray head structure further comprises a temperature sensor arranged on the nozzle and a controller arranged on the heater, and the controller is electrically connected with thetemperature sensor and the controller. According to the spray head structure for three-dimensional printing, the heater is used for controlling the heater to heat the nozzle through the temperature sensor arranged on the nozzle and the controller arranged on the heater, so that the blockage caused by too high temperature or too low temperature is avoided, the spray head structure further has the advantages of being smooth, high in printing speed and high in printing efficiency; and meanwhile, the nozzle made of high-precision alloy is utilized, so that the advantages of being high in printingprecision and long in service life are achieved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printers, in particular to a nozzle structure for three-dimensional printing. Background technique [0002] With the development of science and technology, the modern manufacturing industry has developed rapidly, and 3D printing technology has followed, which continuously meets the needs of enterprises for various shapes and structures and reduces production costs. For example, in the product development stage, the model is processed by a 3D printer. Printing can greatly reduce the cost of tooling. [0003] At present, 3D printing technology is meeting people's personalized needs. If mechanical processing is used to complete the product manufacturing, the processing is difficult, the processing cycle is long, and the cost is expensive. Through 3D printers, people can print personalized products according to their own ideas. However, existing 3D printers, especially desktop 3D printers, ...

Problems solved by technology

[0003] At present, 3D printing technology is meeting people's personalized needs. If mechanical processing is used to complete the product manufacturing, the processing is difficult, the processing cycle is long, and the cost is expensive. Through 3D printers, people can print personalized products according to their own ideas. However, existing 3D printers, especially desktop 3D printers, vibrate significantly during the working process, especially at the printing nozzle, resulting in rough products, low printing accuracy, and high or low printing temperature, which makes printing not smooth The nozzle is prone to clogging, which affects the printing speed, makes the 3D printing efficiency low, and cannot meet people's needs. Therefore, it is urgent to improve the 3D printing technology.
