Suitable standard element material combinations

The objective was to find different and typical tooling steels like special carburised steel, mild steel, corrosion resistant steel, hot forming tool steel, case hardened steel or pre-alloyed tool steel for the application in the laser sintering Rapid-Prototyping process. These materials should be useful as standard elements.

Currently, there is only one material available on the market for this application. It is the original EOS steel plates.

Several investigations were done with different kind of steels. The material investigation was done in the fields of building test structures, measurement of mechanical strength, scanning electron- and light-microscopy of the contact zones.

At the end, several new materials were investigated for the application as standard elements in the lasers interring Rapid-Prototyping process. Following economic reasons the possibilities for alternative materials are given by these results.
