Dear Mr. White,

on behalft of Dr. Petzoldt, please excuse my late answer concerning your question from September.

In fact EOS is the only supplier for “DMLS powder” as EOS is the only manufacturer of “DMLS” systems.

Nevertheless there are competitors in the market doing more less the same process of laser melting:, using their own powders:


– they call it “Laser Cusing”

An der Zeil 8
96215 Lichtenfels

T +49 (0) 9571 / 949-228
F +49 (0) 9571 / 949-239

MTT Technologies GmbH
– they call it “Selective Laser Melting (SLM)”

Roggenhorster Strasse 9c
23556 Lübeck

Tel.: 0451-16082-0
Fax: 0451-16082-250
or an Electron Beam based approach from

Arcam AB – they call it “Electron Beam melting (EBM)”

Krokslätts Fabriker 27A
SE-431 37 Mölndal

T. +46-31-710 32 00
F. +46-31-710 32 01


To produce your on powder from raw materials you can take and mix any adequate powder you like from known powder producers as Hoeganaes or Ecka or H.C. Stark. You “simply” have to adequately adapt your powder and process parameters. A very sufficient material is for example a stainless steel as 17-4 PH as described (on page 3) of the attached file.

I hope this information will be of help for your further plans.

With best regards
