Problems solved by technology

[0002] In recent years, 3D printing has developed rapidly, but due to the high cost of materials and low printing accuracy, 3D printing has been limited in practical applications.
[0003] Traditional FDM 3D printers can only print in a single direction. In order to solve this problem, many experts are working on multi-directional FDM 3D printers, but most of the multi-directional FDM 3D printers use the method of splitting first and then printing. , the printing method divides the model into several parts and prints them se
