I designed a high detail part that I do not have the ability to produce myself. I was thinking of getting someone on 3DHubs to SLA it. Does anyone have any idea if an SLA clear resin part will work for use with casting rubber to make a mold for a 2 part epoxy or plastic or similar? It really seems like a lot of work and I am not sure how long the rubber molds will last considering some of the 1mm deep details of about 0.2mm thick lines in lettering in the design. It about makes me wish I had an SLA printer of my own. The parts are essentially 78mm diameter by 4mm thick discs with details on the discs. I have not tried stacking multiple discs to see how it affects the quotes. I am considering redesigning the part so that the minimum line thickness is 0.5mm or even 1mm. If the minimum cavity size is 1.5mm, I could even CNC mill it.
@Rene_Jurack did it I believe. Might want to check his site to see if there is any info on it. If I remember correctly he had custom made heat block socks made using that method
Indeed, the molds for the silicone covers for his hotend are made from sla. Results are good.

This is why we bought SLA in the first place. It works perfect for this application. The best thing is, you can polish the printed part, sand blast it or whatever to achieve desired surface. Look up videos on YouTube on silicone moulds from printed models.
