I tried resin printing a different flywheel design yesterday. It would have turned out as a usable print, but the resin ran out before the print was complete! The photo shows the inside of the print, not a view I often get to see. After my initial annoyance I realised that failing in this way had given me a chance to see where a lot of distortion I have been getting in my larger prints was coming from. In this case it was the internal support structure generated by the slicer software, Lychee (Prusa slicer produces similar internal supports that also create distortion). Wherever there was an internal support, there was external surface distortion. This made me wonder if my slicer settings were wrong for this type of print. I will be printing a flywheel tomorrow with the adjusted settings, increasing the exposure time for the layers will hopefully make the outer skin stronger and less liable to sag. So a fail, but it could be teaching me something.
