Hi guys, it may seem like a simple problem but I’m really struggling trying to find a solution.
I’m printing with PLA at about 200 on a non-heated bed. If I’m printing something even mildly technical which causes the layers to print in an outward direction, I get really bad curling on the edges. I can just about finish the model but it causes unsightly defects which might as well be failures.
One thing I don’t understand however is that some of the edges that were printed in a specific direction come out perfect but the other edges curl. Have a look at the images of a dice tower I printed recently, the underside of the slopes on one side are perfect, but on the other side, they’re all nasty and curled. Any advice would be greatly appreciated.
Cheers!

Since it doesn’t have to do with the X-Y Direction would say it is a cooling problem. The Material on the left picture did cool down to slow, where as the right picture is did cool down fast enough. It seems like you don’t have an active cooling. So the only thing you can do is to slow down the printing speed.
Or does it depend on your startpoint of each layer?

I would’ve thought it would have something to do with the X-Y directions though surely as it only effect the layers in one direction?
put a box fan or other portable fan blowing across your bot, as some filament coolers only cool from front to back, instead of making a ring around the nozzle. Do you use something like Active Cooling Fan Duct v2 for Replicator 1 / Duplicator 4 / FlashForge / CTC by thruit00 - Thingiverse ? Print that if not. There is an extra fan, under your printer, pointed at the motherboard. This is seriously just a leftover mistake from MBI’s poor engineering and is no way needed to cool the motherboard, its a free 40mm 24V fan for you to use.
