Printing a PLA VAT - horrbile idea?
Posted: Sat Aug 23, 2014 5:54 am
Hey guys,
I'm currently working on my first bottom-up DLP and as I already have an UM2 here I wanted to print as many parts as possible to save on costs (and hopefully time).
My plan for the VAT so far is working with a sheet of tensioned FEP. What i'm obviously curious about is wether the combination of PLA and resin would be a bad idea or not as I'd like to print the whole thing (except for the bottom of course). Will one of the materials react with the other? Will the PLA just degrade and start to leak?
I'll probably need quite thick walls to make sure everything is rigid enough, but that's the last thing I'm worried about at this point.
If the resin doesn't like the PLA would Nylon work instead? Or could I possibly seal the PLA with polyurethane or something?
I don't have any resin here yet to test it myself as the whole build is still weeks or months away (mostly a budget question), so if someone already has experience regarding PLA parts that are exposed to resin I'd be more than grateful to get some insight
