Description

technical field [0001] The invention belongs to the technical field of rapid prototyping, and in particular relates to a selective area plasma melting rapid prototyping equipment and a rapid prototyping method. Background technique [0002] At present, the rapid prototyping technology of metal parts at home and abroad includes the selective laser melting rapid prototyping technology (Selectivelaser melting, SLM). For example, the U.S. patent "PROCESS AND DEVICE FORPRODUCING A SHAPED BODY BY SELECTIVE LASER MELTING" with the patent number US7047098 describes in detail a selective laser melting method and equipment for manufacturing dense parts using a three-dimensional digital model. The Chinese invention patent with the publication number CN1603031A "A Method and Device for Selective Laser Melting Rapid Prototyping of Metal Parts" discloses a method and device for selective laser melting rapid prototyping of metal parts. The device includes semiconductor pumped YAG laser or...

AI Technical Summary

Problems solved by technology

This makes the structure of the selective laser melting rapid prototyping equipment complex, and the size of the molded parts is limited

[0007] Second, the laser spot diameter is small, the power is low, and the efficiency of forming large parts is low

Lasers are expensive and expensive to maintain

This makes the equipment cost of selective laser melting rapid prototyping technology very high
