3D printing device

Abstract

The invention discloses a 3D printing device, which comprises a printing mechanism, a frame mechanism, a platform mechanism, a heat preservation cabin and a supplying mechanism. The printing mechanismis arranged at the upper part of the frame mechanism, the heat preservation cabin is arranged within the frame mechanism, and is located at the lower part of the printing mechanism, the platform mechanism is arranged at the lower part of the printing mechanism, and the supplying mechanism is connected with the printing mechanism; the 3D printing device ensures accurate printing of a printed matter through the printing mechanism and the platform mechanism, and keeps the printed matter warm during the printing process to prevent the printed matter warpage and deformation, and the printing effect is further improved, because the printing mechanism is arranged on the frame mechanism, the frame mechanism has less welding, small deformation, high vibration absorption capacity and good rigidity,and the printing accuracy is improved; and the amount of silk materials can be monitored in real time through an encoder to find out whether the printed silk materials are blocked.

Description

technical field [0001] The invention relates to the technical field of catalyst loading, in particular to a 3D printing device. Background technique [0002] 3D printing technology is a kind of rapid prototyping technology. The FDM process is the most widely used type of 3D printing technology. Because it can quickly produce complex parts, it can quickly evaluate and modify products to respond to market demand. FDM melt deposition forming heats the thermoplastic material to a molten state. Under the control of the computer, the nozzle sprays the molten liquid on the worktable according to the cross-sectional contour information of the part. After cooling, a layer of cross-section of the workpiece is formed, and a layer of molding is formed. After the completion, the workbench is moved down one layer higher, and the next layer is applied again, and the layers are piled up until the parts are manufactured. However, during the printing process, due to the rapid heat dissipatio...

Problems solved by technology

FDM melt deposition forming heats the thermoplastic material to a molten state. Under the control of the computer, the nozzle sprays the molten liquid on the workbench according to the cross-sectional profile information of the part, and forms a layer of cross-section of the workpiece after cooling, forming a layer. After the completion, the workbench is moved down one layer higher, and the next layer is applied again, and the layers are piled up until the parts are manufactured. However, during the printing process, due to the rapid heat dissipation of the printed parts, it is easy to warp and deform, which seriously affects print effect
