PDMS Problem

Postby nightblade » Mon Sep 19, 2016 10:24 am

Im using pdms 3mm thick in acrylic with 3mm, in the first print pdms becomes cloud. I don't know why pdms becomes cloud...
This is about temperature? About the exposure time? About the distance between pdms and bed? Someone have this problem too? Someone can help me?

PDMS and resin can have some reaction make PDMS cloudy when resin get cured. you may need to change a new PDMS after several prints. apparently your resin has badly reaction with PDMS, I suggest you use some other brand resin.

If you don't really care print quality, makerjuice is the best option, it's very cheap, easy to peel
formlabs resin is a better one, but also more expensive than B9
the envisiontec PIC 100 is the best resin I have ever used, but the price is also way too expensive.
