Print curves up at edges/corners?
Hi all,
I've been getting some great results with my printer lately. However, my latest print, while useable, came out a little less great. The edges, especially the corners, kind of curled up. You can also see there are a couple of layers that seem to have been particularly problematic. In the side view, you can see the curling seems to have fixed itself by the time the second bad layer was laid down. Any ideas what happened here, bot the curling of the edges and the few bad layers?
This print was the longest one that I'd printed at around 30 hours, these bad layers probably went down a few hours into the print or so I'd guess.

Warping is a very common occurrence with large rectangular objects.
Assuming Live Z is well calibrated and the steel sheet is clean (using hot water and fragrant-free dish washing soap), here are a few approaches that have worked for me:
- Slow down print speed.
- Add mickey mouse ears to the corners. You can add a cylindrical part in PrusaSlicer, maybe 10mm diameter, change height to single layer height, then place the part at the corner. Repeat for each corner.
- Add a brim around the model, 5 mm or more.
- Use Layerneer Bed Weld ( https://www.amazon.com/Printer-Adhesive-Layerneer-Original-Filament/dp/B079984GV5/). You need only a thin layer.
- If you have design control over your part and it's possible considering the intended use, you can try to round the edges and/or add holes to the base of the model.
- Combination of above. Usually, Mickey Mouse ears or brim and Layerneer works for me, but large, rectangular objects can be a challenge.

Thanks, this is super helpful! I didn't know that about large rectangular objects. I've added brims before, and that's real easy. I'll mess around with the Mikey Mouse ears as well next time I do something like this.
Thank you!
