Did you run the Perfactory parts through a flash-oven (which
blasts them with high-intensity light) before burning them out?
That's supposed to cure the resin that remains inside the parts
uncured through the build process, promote melt-out, reduce ash
formation, and speed up the burnout cycle. 17.5 hours seems like a
long time. Are these fairly big flasks?
I don't do my own printing, I have various service bureaus do that
for me (soon I hope this to change). The company I have printing my
models on the Perfactory machine do cure them in a flash oven and
this burnout cycle is their recommended cycle. They cast as well as
print so I trust their input. The flasks I am casting are ususlly 3 X
6 inch and contain a number of models on a central tree. I agree that
17-1/2 hours seems long but at their given temp hold times and the
ramping rate they advise, this is what it works out to and the
castings have been very successful; so I haven't attempted to change
the schedule they 1st recomended.
If you have another burnout cycle which you use for the Perfactory
+/or Viper models please post it to the group, I'm always open to
better, quicker, more cost effective suggestions and I am very
willing to try new techniques. Personally, I like Solidscape models
for their easy burnout properties, but some modelsare better done in
resin printing to get the fine detail and the durability I frequently
need for my clients products.
Thanks for the comments! I hope you can provide an effective, faster
