[0002] 3D printing technology, as one of the manufacturing technologies that has developed rapidly in recent years, has the core principle of decomposing complex three-dimensional objects into a series of simple two-dimensional layers, and finally completing the construction of three-dimensional objects by stacking these layers layer by layer. In the field of sand mold 3D printing, with the continuous expansion of printing size, the accuracy of printing sand molds has become increasingly prominent and has become a core element of design control. This requires the frame structure to have higher stability and load-bearing capacity. During the printing process, a stable frame structure is crucial to supporting the printed object. It can effectively prevent the printing effect from being damaged due to vibration, deformation or collapse of the printed object during the printing process. The existing 3D printer frame is mostly assembled by welding multiple profile parts. This structure is prone to quality problems such as deformation. In addition, due to the limitations of the welding process, the overall dimensional accuracy after molding is difficult to guarantee, resulting in unstable product quality. At the same time, the weight of this frame is relatively light, the seismic performance is poor, the processing process is cumbersome, the production efficiency is low, and the cost is high. Therefore, it is necessary to optimize and improve the existing 3D printer frame to improve its quality stability and production efficiency.
