A multi-degree-of-freedom 3D printing platform

Abstract

The invention relates to the technical field of 3D printers, in particular to a multi-degree-of-freedom 3D printing platform. The multi-degree-of-freedom 3D printing platform comprises a box body anda processing head, and further comprises a supporting plate, a cleaning mechanism, a mud scraping mechanism and a lifting mechanism. According to the multi-degree-of-freedom 3D printing platform, thelifting mechanism can drive an operation table to move up and down and transversely rotate, so that the degree of freedom of a printer is wider, and the printing effect is better; when residues existon the operation table, a second button can be pressed down, so that a dirt scraping base can automatically move along a sliding groove under the elastic action of a second driving mechanism, so thatthe residues on the surface of the operation table are scraped off, and the scraped waste can be gathered through a semi-circular groove-shaped push groove, and finally the scraped waste is pushed toa first collecting groove for collection so as to be used for next fusion utilization; and the surface of the operation table can be wiped through a sponge column on a cleaning base, so that the surface of the operation table is more smooth and clean, and the subsequent printing precision is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a multi-degree-of-freedom 3D printing platform. Background technique [0002] 3D printer is a fusion extrusion molding technology, also known as fusion accumulation molding. The basis of this process is to heat and melt thermoplastic polymer materials into filaments, extrude from the nozzle like squeezing toothpaste, and accumulate on the molding surface to form. The equipment covers From the construction of fast concept models to the different application areas of slow high-precision models, the materials are mainly polyester, ABS, elastomer materials, and wax for investment casting. [0003] During the 3D printing process of the current printing platform, the position of the workpiece is relatively fixed, and there is no effective up and down movement or rotation, which limits the degree of freedom of the printer and affects the printing effect of the workpiece; There are ...
