Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing equipment technology, and in particular to a 3D printing and laser cutting integrated machine. Background Technology
[0002] 3D printing is a rapid manufacturing technology that can directly manufacture various complex-shaped solid parts according to a pre-set digital model under the program control of PCs (including touch screens with computer systems). Specifically, different 3D printing technologies include fused deposition modeling (FDM), solidification photopolymerization (SLA), selective laser sintering (SLS), etc. These technologies provide reliable manufacturing methods for parts production. In order to ensure that the quality and size of the printed parts are not too small, in the existing technology, especially in some precision manufacturing fields, the parts printed by 3D printers are usually larger than the design size. The larger size of the parts has the following advantages: (1) Preventing material shrinkage: Specifically, during the 3D printing process, the material will undergo a shrinkage process after being heated and melted and then cooled and solidified. In order to compensate for this shrinkage, setting the size larger in advance can ensure that the size of the part after printing is closer to the design size, reducing dimensional errors. (2) Preventing interlayer adhesion: Specifically, 3D printing builds objects by stacking layers one by one. Each layer needs to be well bonded. Setting the size larger in advance can ensure that the adhesion between layers is stronger, reducing the risk of delamination or detachment. (3) Ensure printing accuracy: Specifically, the printer's accuracy and layer height settings affect the dimensional accuracy of the final parts. By setting them to a larger value in advance, the printer's insufficient accuracy can be compensated for to some extent, ensuring that the dimensions of the parts are more accurate. (4) Ensure wall thickness and infill density: Specifically, wall thickness and infill density are important factors affecting the strength and surface quality of parts. Setting them to a larger value in advance can ensure that the wall thickness and infill density meet the design requirements, thereby improving the strength and surface quality of the parts. In addition, during the 3D printing of biological scaffolds, the edges are often more defective due to the slower printing speed caused by the curves, and the actual size will be larger than the design size.
[0003] Laser cutting is a precision cutting process capable of cutting various materials such as metals, plastics, and ceramics. It is characterized by high precision and efficiency. Therefore, in current technology, for parts printed by 3D printers that are too large, laser cutting machines are often used to cut them to meet the set size requirements. Currently, 3D printers and laser cutting machines are separate devices. In practice, after the 3D printer finishes printing, workers manually remove the parts from the printer and place them under the laser cutting machine for cutting. This operation mode is inconvenient for workers and consequently hinders work efficiency. Utility Model Content

The touch screen 1 is fixedly installed on the front left end of the housing 10. The housing 10 is an aluminum alloy frame structure, with a surface covered by tempered glass and engineering plastic panels (providing good safety and visual effects).
