Hi William,
The electron beam system would be from Arcam. There are many service
providers and researchers using Arcam EBM technology worldwide. Some
are listed on our website.
Building successful parts in SLS, DMLSR, SLM, or EBM with new metal
powder formulations is not trivial and can take many man hours of
process development. Good luck!

There are both laser and electron beam systems. I think the EB systems
are Arc-cam, not sure who the laser system is.

General question:
What type of rapid prototype machine uses metal powder and sintering
process? My partner has created a new steel formula that has very
useful properties and we would like to try to use it in a powdered metal

Hello all,

I'm running into a support issue when supporting a flat area above
another flat area. Basically, the flats are parallel to each other and
the platform. Distance is irrelevant . The beginning support from the
platform to the first flat is fine. It's the bottom of the support
structure (which should attach from the top surface of the bottom flat)
seems to lose itself as it grows higher and eventually doesn't attach to
the bottom surface of the above flat. At times I lose most of the
support but some grows in the "stringy, fuzzy" mode. I've increased the
overcure and also increased the bottom contact. Sometimes this works but
I still have issues. I hope I didn't confuse anyone. Any suggestions
will help.
