I’m working with a FormLabs 3BL and have just had a major print fail where 5 of 6 of my parts have come out mal-formed. I’m guessing I need to add more supports in the centre, can anyone confirm this?
If so, I used auto-generated supports. Why did PreForm failed to pick up that these supports were needed? What should I be looking for when considering if parts need more support than PreForm automatically provides?
I’ve never seen anything like this before and I can’t imagine it’s got anything to do with the orientation when draining! I’ve left prints for days draining and never seen any distortion.
Hi.
The parts look hollow and very thin-walled, am I correct? If the design wall is a bit too thin for the material, you can have ‘skins’ appear in the material… basically, it’s like uncured material that should have attached to the object but failed. Check the tank for floating debris and/or material bonded to the optical film. I’ve had this happen a few thin-walled items. Also, consider “internal supports” as an option. I realize it probably it’s a good idea. Your device looks like it needs a smooth interior.
