Single-screw desktop level 3D printing consuming material forming machine and control method thereof

Abstract

The invention provides a single-screw desktop level 3D printing consuming material forming machine. The machine comprises a driving mechanism, a screw, a funnel, a material cylinder, a heater, a heat collector, a thermocouple, a temperature controller and a nozzle, the driving mechanism is connected to one end portion of the screw, the other end portion of the screw traverses through one end portion of the material cylinder and then is sleeved in the material cylinder, the material cylinder is provided with an opening, the opening is close to the end portion of the material cylinder, the screw goes through the opening, the funnel is connected to the opening, the other end portion of the material cylinder is connected to the nozzle through the heater, the heat collector is arranged at one side of the heater, the thermocouple is used for collecting the temperature signal of the heat collector, the thermocouple is connected to the temperature controller, and the temperature controller is electrically connected to the heater, and carries out controlled adjustment of the temperature to guarantee a stable consuming material melting temperature.

Description

technical field [0001] The invention relates to a single-screw desktop-level 3D printing consumable forming machine and a control method thereof. Background technique [0002] At present, the plastic filaments used in 3D printers are mainly processed by industrial plastic extruders. This processing method has high efficiency and good quality of extruded products, which can realize factory-scale production, and has relatively complete supporting equipment. However, the existing plastic extruder processing equipment has large volume, high energy consumption, and many auxiliary equipments, and a certain production volume is required to start production, which cannot meet the needs of individual users. [0003] In recent years, the 3D printing industry has entered people's sight at a rapid speed in China. Its wide application makes people have infinite associations with its future market space, and is even hailed as an emerging industry leading the third industrial revolution. ...

AI Technical Summary

Problems solved by technology

However, these advantages are also disadvantages at the same time: the industrial plastic extruder equipment is bulky and energy-consuming, and it must have relevant auxiliary equipment to produce qualified products. At the same time, it must have a certain amount of production to start production, so it cannot meet Less quantity, more variety demand

In addition to the above defects, some 3D consumables have moisture absorption and are not easy to preserve. 3D printer consumables need to be produced and used on site. At this time, industrial extruders are helpless.
