Metal 3D printing straight to the casting process, traditional casting how to survive

The advantages of metal 3D printing, can form any complex shape, and the product strength is not weaker than casting, dimensional accuracy is higher than casting.

But, for now, metal 3D printing has 3 major defects, resulting in a short period of time can not replace casting.

1, metal 3D printing is a layer of metal powder coating accumulation, and then sintered with a laser, resulting in the printing of products slower (casting dimensional accuracy, the higher the finer the delamination, the more times the print, the longer the time), this point on the efficiency of casting can not be compared.

2, metal 3D printer, the current high cost, is also a major flaw.

3, metal 3D printer, spraying products, its working parts are used frequently, theoretically, the service life will not be too long, reliability needs to be improved.

So, the current 3D metal printing process, in new product development (such as new product performance verification), less investment, high efficiency, very popular, and really into the mass production of metal parts, but also need a long time!

Again, even if the metal 3D printing eventually replaced the traditional casting, the traditional casting industry can introduce metal printers, practitioners can switch to 3D metal printing, to 3D printing needs of 3-dimensional modeling, process control and equipment maintenance.
