Ugly wrinkled corners

Recommended Posts

It's because of the severe overhang - for one layer it's about 85 degrees from vertical. A solution might be to flip it over so the bottom is down as shown in picture but add brim. This way the layers that I assume are visible will have better quality and the ugliness will be hidden on the underside.

Or you can do what IrobertI suggests at 3dverstaken (forget the exact name as I'm traveling today) and do a 45 degree initial angle and blend that into a curve. He's got great tips on "design for 3d printing".

Yes. I was talking about the same thing. When you have overhangs you get this exactissue - you get a lip after a few layers and it lifts up and every time the nozzle comes near it pushes the lip back down. This is best fixed with lots of fan. But you can avoid it if you design your model correctly. For example if you flip your part so that *down* is the same as *down* in your photo then you shouldn't have any crucial over hangs anymore.

good tips yellowshark. but today i had the same problem with printing my fan mount in abs

so i get the idea to sketch 2 support walls each 0.25mm thick, the same sizes as my nozzle

to protect the sloping wall from bending. but cura print the walls only when i set wall thickness at 0.125 can i solve this someone other ideas?
