I know there are several topics about this - but I would love to hear from more people who have taken time to investigate warping and how to mitigate it.
From what I’ve seen, warping can be dependent several things:
- Whether curing is done with supports or without
- How long the parts have washed and dried for
- Geometry of part and print orientation
- Temperature
I’ve done tests with and without supports, with lower temperature, with no heat, with no heat then a standard heat + UV cure…but find that there are still some situations where warping is inevitable after curing if one is to use the default Form Cure settings.
I also know that mechanical properties are tightly coupled to a heat + UV cure, whereas a UV only cure will result in lesser mechanical properties (but still better than the green state).
In order to avoid warping, I sometimes will just cure without heat for at least 3X the time. I’ve found that this definitely eliminates warping, but I am sure mechanical properties are impacted.
One thing I haven’t tested a lot is the amount of dry time and wash time and how those affect the amount of warping one sees. Curious if anyone has some test results or knowledge from that.
Also am curious if the Form Cure L does anything differently to mitigate warping during this step.
