Try to be a little more specific. There is nothing typical
particularly if you are a service bureau.
However, with DTM's RapidTool #1 metal there is a point of diminishing
returns. The weight of the iron powder upon itself, and due to the
light tacking together of the powder, can cause sinking. We have
built RapidTool molds 3.5" in the Z and found very minor cavatation.
Fortunately, the area was on the mold parting line where we allowed
We anticipate DTM's new RapidTool #2 will substantially reduced this
issue. Their new materials are processed in the sinterstation with a
binder between the spherical metal powders eliminating the oven drying

I am interested in the typical weights of the models/patterns that are
made with either the DTM or EOS SLS processes when metal powders are
used as the "build" material. It would appear that a model made
anything close to the maximum size would be extremely heavy.
Your feedback would be appreciated.
