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.
