Abstract

The invention discloses a high-voltage static drive and variable-diameter 3D (three dimensional) printer belonging to the field of 3D printing. The high-voltage static drive and variable-diameter 3D printer comprises a charging barrel, a heating coil and a thermocouple which are wrapped outside the charging barrel, a columnar runner connected with the charging barrel through a bolt and a gasket, and a converter connected through a bolt and fixed at the bottom of the charging barrel, wherein the converter comprises a fixing ring and a rotary ring, the fixing ring has a columnar spring hole, a metal ball the outer diameter of which is slightly smaller than the diameter of the columnar spring hole is connected into the columnar spring hole by using a spring, the fixing ring further has a through hole tightly matched with the columnar runner, the rotary ring can have at least two threaded holes connected with nozzles, semi-spherical grooves matched with the metal ball are arranged corresponding to the threaded holes, one or more needle heads with equal diameters are connected to the nozzles by using threads, diameters of the needle heads corresponding to the nozzles are different, the needle heads are connected with an anode of a high-voltage static generator, and a receiving device is grounded. The high-voltage static drive and variable-diameter 3D printer is suitable for a 3D printing system with a melt or solution as a raw material; needle heads of different diameters are obtained through converting the nozzles; and the high-voltage static drive and variable-diameter 3D printer is driven by high voltage static, and thus the variety of 3D printing materials can be increased, and the quality of a 3D printed product can be improved.

Description

technical field [0001] This patent relates to a 3D printer, in particular to a 3D printer driven by high-voltage electrostatics and variable diameter, which belongs to the field of 3D printing. Background technique [0002] 3D printing, namely "rapid prototyping technology", is a technology that can accurately make a physical model through the forming equipment in the form of material accumulation based on the three-dimensional model data of the entity, and hardly any waste will be generated during the production process. thing. The consumables for 3D printing are materials that can be cured, such as metal, plastic, and ceramics. As the technology matures, 3D printing technology will be widely used in industries such as medical care, food, jewelry, construction, personalized products, cultural relics protection, aviation, automobiles, and electronics manufacturing. However, the types of materials that have been applied to 3D printing are limited, and the printing accuracy ...
