[0001] The present invention relates to the technical field of 3D printing, and in particular to an integrated 3D printing and milling composite processing training platform. Background Art

[0002] With the development of 3D printing technology, 3D printers have been able to directly manufacture metal parts with metallurgical bonding, dense structure, dimensional accuracy and good mechanical properties. They have broad application prospects and have become a research hotspot in the field of additive manufacturing. 3D printers print metal parts with the advantages of personalized design, fast molding and short manufacturing cycle, which are very suitable for the manufacture of small batches, personalized metal parts with complex surfaces and internal structures.
