Re[2]: Tooling Resins vs. SLA

     Our experience using any cast composite resin systems...
     Success is part geometry dependent, part size dependent, molding resin
     processing pressure dependent and molding resin processing temperature
     dependent. There are many more factors which affect outcome.
     We seen molds blow apart on the 2nd shot and others produce in excess
     of 250 shots...
     I cannot imagine SLA resins having any better success ratios then
     epoxy systems.

We did some R&D with SLA molds and found they wont last more than 5 shots in an
injection press with production material. The same study showed a high heat
mold lasted about 10 shots. If anybody has any information about this I would be
interested to hear it as well.
