Alvaro Rodriguez Posted March 1, 2021 Share Posted March 1, 2021 As said in previous replies, resin warpage is more evident in some parts. The thin and large surfaces of wings –like we are seeing here- are one of those candidates for such adverse effect but this applies to almost every flat surface often. Fact is that most UV resin have some warpage at some extent and some resins are better than others like the –expensive- dental ones. But resin warpage could be also a side effect of not fully cured prints too. Just for double-checking, may I ask if you are curing your prints in water? I think that´s what Finn is suggesting his first post and I would recommend you to give a try if you are not doing it yet. These UV resins suffer from a well-known effect called oxygen inhibition. Long story short, and like its name suggests, the air in contact with the resin may prevent it from fully curing. And that´s why when you are dipping your prints into water for curing you are avoiding that actually. So simple. This “water curing” also has a beneficial side effect if/when you are curing your prints under direct sun light and it is that the print does not overheat, curing with a rather stable temperature thanks to the water –that gets warm at most- too. Note this will ensure you will have fully cured prints (so we are deleting the warpage due partial curing here) but this may –or may not- prevent warpage over time. As said, that´s related to the resin properties. I might be plain wrong here but if a print is fully cured I do not think that further exposure to room / ambient UV light could have any adverse effect so I do not see the need of an additional and protective layer onto it (like paint or primer). If that´s an issue then what you would need would be UV resistant paints / primers / varnishes for sealing the print then. Regards!
