Stainless Steel 15-5

Direct Metal Laser Sintering Material

Stainless Steel PH1 is a pre-alloyed stainless steel in fine powder form. The chemistry of Stainless Steel PH1 conforms to the compositions of DIN 1.4540 and UNS S15500. Standard processing parameters use full melting of the entire geometry with 20μm layer thickness, but it is also possible to use 40μm layer thickness to increase the build speed. Using standard parameters the mechanical properties are fairly uniform in all directions.


This material is ideal for many part-building applications (Direct Part) such as functional metal prototypes, small series products, individualized products, spare parts, parts requiring high corrosion resistance, sterilisability, high toughness and ductility.
