I appreciate the offer of help, but things seem to be getting a bit confused here, so let me clarify this before it goes any further. : )
- This thread has nothing to do with tank life, no matter what the resin.
- I make movie props and replicas. When I bought the Form 2 in 2018, I went through about 4-5 liters of Tough, and could not get warp-free prints. (Formlabs printed tests, I printed tests, my local reseller printed tests- they ALL warped. Formlabs’ techs finally concluded the Tough V5 resin could not produce the warp-free prints I needed. Prints also collapse/deform over time- thin parts even under their own weight. Tough resin goes soft under regular warm tap water as well. This was all discussed here on the forums.
- Tests printed in Rigid, turned out nice and straight.
- Tests printed in Durable came out warped- perhaps even more so than Tough!
- Tests printed with Dental Model deformed and collapsed completely during shipping.
Here are a couple of the deformed parts in Tough V5.
In this image, you can see major warping in the 2-4mm thick walls. I managed to correct a little by baking the parts clamped onto a steel brace. Still not good.
Here you can see how the part widens a lot toward the bottom, which was closest to the build plate.
After that I switched to using only Grey Pro, and it has been pretty great, BUT even more durability would be good.
I’ve been hoping Formlabs would come out with something that’s a cross between Grey Pro and Tough- precision, better heat deflection, no warping and stability over time. Tough 2000 seems like it MIGHT fit the bill, but with the current crisis, it will take Formlabs a longer time to get a sample print out to me, so I figured I’d ask here if anyone was using it yet.
So… for those that have tried it, some reviews would be awesome!
