It can and does work...If you team up with a house that knows how to
build molds. Depending upon the complexity and customer expected
outcome it delivers NEAR-NET-SHAPE. If your design has significant
engineering design features. e.g. deep bosses, ribs, shut-offs, etc.,
then using good mold making practices like inserting complex features
makes sense. It's fast but requires a good working knowledge of the
sinterstation, intermidiate infiltration oven and the furnace. The
green part is as close to perfect as one would normally expect for
injection molding tolerances unless your doing precision AMP type
connectors where tolerances are typically .001"/" ot tighter. It's
great where you have extremely complex geometry. The furnace stage is
where problems occur, but with experience you can learn to anticipate
There's no silver bullet yet! DTM's process is as close as anyone has
gotten with a non-transfer (3D Direct) approach. It's an ideal
solution, yet still needs DTM and users to push it further. What is
needed is customers who purchase tools to embrace it as a new tool
making process and commit to being part of a learning curve.
Hopefully these pioneers will benefit by being ahead of their

Can someone shed some literature on Rapid Tool by SLS process. Hows the
process, is it as good as claimed and whats the latest discovery.
Thanks to all speedy contributors.
