A frame-type five-degree-of-freedom 3D printer

Abstract

The invention belongs to the technical field of 3D printing, in particular to a frame-type five-degree-of-freedom 3D printer, which includes a printer frame and a sliding arm connected by a slider passing through the top of the printer frame, and a printing plate connected by a slider on one side of the sliding arm. Spray head, both sides of one end of the sliding arm are connected with cooling boxes by bolts, pipe grooves are opened on the top side of the two cooling boxes, slider grooves are opened on one side of the two cooling boxes, and two The corners of the upper surface of the cooling box are provided with cold air inlets; the present invention is equipped with a cooling box, so that the printing nozzle slides into the inside of the cooling box through the slider, and the surrounding air is sucked in and refrigerated by the air condenser, and passed The cold air pipe and the cold air inlet blow the cold air into the air slot. After the air reaches the inside of the cold air slot, it will blow to the surface of the print head through the cold air outlet.

Problems solved by technology

[0002] Existing 3D printers mostly use unidirectional layered fusion deposition technology, that is, the printing nozzle has a fixed posture, and the three-dimensional entity is divided into several planes along the direction perpendicular to the printing nozzle, and the material is added layer by layer to obtain the final product. This method has a trajectory It has the advantages of simple planning, fast manufacturing speed, and low cost; however, the 3D printer using unidirectional layered fused deposition technology is limited by the number of degrees of freedom of the printing arm of the printing head, and the surface quality of the printed object is poor, and the same The surface quality of different parts of the article is uneven; when using the existing 3D printer to repair the entity, due to the influence of the position of the printer nozzle, there is often interference between the entity workpiece and the print head, which affects the repair effect; in addition, due to The objects printed by the unidirectional 3D machine are all piled up by unidirectional materials, which makes the mechanical properties of the formed objects directional

[0003] At the same time, at present, in the printing process of 3D printers, the temperature of the print head itself is high and the temperature cannot be effectively cooled in time. However, the general 3D printer has only one print head. Working in a high-temperature environment for a long time may easily cause the print head to be damaged. Deformation due to high temperature corrosion will shorten its service life and cause inaccuracy of printed objects
