I’m trying to print a gasket where the diameter should be 36mm but after I washing the gasket I noticed it was very much oversized and when I measured the diameter it was just shy of 40mm which makes it OVER 10% LARGER. Has anyone else seen this in their Elastic 50A prints? How do I correct this really huge oversizing? Is it a software issue? I actually know I improperly washed it I only dropped the gasket in the basic IPA wash and I didn’t put it in the Form Cure but I’m not sure how that would shrink the gasket to the proper size. The gasket is pretty thin (0.5mm), would that be a factor in the oversizing? PLEASE HELP!!! ![Untitled](https://us1.discourse-cdn.com/flex025/uploads/formlabs/original/3X/0/3/0335aa5020eacf47f860683779c0885a35dc9ea7.jpg) ![dim](https://us1.discourse-cdn.com/flex025/uploads/formlabs/original/3X/f/a/fadf00c557388361a7e99b57edb79c6c57594723.png) ---

Thin parts in Elastic are prone to swelling during washing by absorbing IPA, and 0.5mm is really quite thin, making this part especially susceptible. Things you can try: 1. Wash it for a much much shorter time. 2. Let it dry out for a long time before post-curing, and it may shrink as absorbed IPA evaporates out of it. 3. While wearing gloves, hand wash it using as little IPA as possible. I thought Formlabs had something in the finishing instructions specially about thin features, but I don’t see it, just a general warning not to leave Elastic parts in the was for too long. ---
