I have a large, flat part just printed in Clear v4. Would it be ok not curing it do not risk warping and having it slightly less yellow? ---

I believe I have seen people do that before. You would have to let it naturally clear from either sunlight or ambient light so its not as sticky. Formlabs also has a how to on making clear resin optically clear that you can check out and there is a process called “dipping” and they don’t mention introducing any heat, just UV. > **[Creating Camera Lenses with Stereolithography](https://formlabs.com/blog/creating-camera-lenses-with-stereolithography/)** > > Dig into the design behind the first fully 3D printed lenses for an interchangeable lens camera, produced entirely on a stereolithography (SLA) 3D printer. ---
