The PEEK moulding I did was at a melt temp of 750 degrees F. The most
complex part was an impeller for a motorcycle engine. I think I have a paper
on this as well if useful.

REL,

 

I have been successful with SI-40 for sanopreme. Melt temperature up to and
not exceeding 500 degrees F. Contact temperature was down around 270 degrees
F. Anything higher than that gave thermo cracking to the SLA material.
Cycling was around 2 1/2 minutes and I ran the mold cold. For you first mold
run 4 degrees draft on your mold. Yes, that is allot. Good luck and let us
know how you make out.

What is the experience of the list members when it comes to SLA resins for
rapid tooling? What would you recommend for a low pressure injection
molding application where the injected polymer temperature is 350 F.

 

Does the ZPrinter material filled with epoxy have a chance at working at
this temperature?
