What printer style to purchase for high density thermoset peices?

Umm, you either want an sla or you don't

As for the 250c - would the part need to withstand that high a temp ?

Ultimately I am looking for an alternative to the Stratasys PolyJet Process using DigitalABS (due to the extreme expense of the Stratsys printers).
I will be using the printer to produce injection mold tooling for prototyping.

For that reason I need to be able to produce 3D prints having very high density (low porosity) and high melting temps.
The plastic also must be a thermoset material so that it will not interact with the thermoplastic injected into the mold.

I believe SLA is my best bet, but wanted to tap the collective knowledge of this community first.

just out of curiosity - what temperature do the uv resins for sla machines actually melt at ?
I'd think it would be quite high - but no clue really :-)

This is a good question as well. I would like to know the post-cured melting temp of the UV resins used for SLA.

Looks like 3Dsystems make a producte that when post-cured and heat treated can achieve a Heat Deflection temp of 513°F+
