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 application.

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.
