Materials and Applications

Steel Powder

Steel powder for DMLS Sintering prototypes

The following are the characteristics of the most common steels used for the production of short runs through precision casting.

Features

average data of the steel powder materials obtained

In prototyping the combination of material and processing technique is one of the most complex choices. Executing a prototype almost always requires evaluations so that, for the technicians’ use and consumption, the average characteristics of the materials obtained by prototype construction are given. These can be used to get an idea of ​​technical and functional compliance.
