Dear Frédéric Gillot,
I can send you a presentation I made from last year
EuroMold at RAPTIA seminar, about the possibilities
one have to make prototypes in magnesium.
(It is 3.2 Mbyte in PowerPoint format.)
Most common way to produce a single magnesium
prototype, is to use investment casting from another RP part.
Several RP service-bureaus in Europe offer investment
casting of magnesium parts from prototypes.
If you want to make a prototype using magnesium
high-pressure die casting, you have to make a die using
conventional methods, or you can use SLS sintering with 20 micron
steel powder. I suggest you contact dr. Richard Hague
(r.hague@lboro.ac.uk) at Loughborough University for
more practical info on rapid tooling for magnesium
high-pressure die casting.
Check AGIL cast AG of Switzerland (www.agilcast.ch).
They produce equipment for vacuum investment casting
of magnesium, which have similar material properties as one
made with HPDC.
I am also told that Z-Corp (www.zcorp.com) can produce
pouring mould for magnesium directly using 3D printing
and a new technique called Z-Cast. We have not tried it
yet, so we have no experience with it.
Best regards,
Geir

Dear list,
Well, I'm currently working on a project aiming at building Mg part
(AZ91) using some RT process.
So I was wondering if anybody has ever heared or worked on a way to
manufacture prototype part in Mg. More specifically, what sort of RT
process you (will) use to build such part... and why ?
Regards
