Curling Ends and Corners

[rmahpoy]

When we print phone cases or buildings the ends and corners curl up. Is here a way to prevent this?

A skirt can help keep corners down.

When I run ABS or nGen material, I’m always near the printer when the print is almost done.

If there is room on the bed while the print is going on, I fold a paper towel and place it on the bed.

After the print is complete and the extruder parks itself, I wipe off the extruder tip with a rag and then

I place the heated paper towel over top of my parts.

The bed takes longer to cool down to part removal temperature and with the part covered,

I think the part gets heated uniformly.

I have very little curling of ABS or nGen when I do this.

and

As garthvh suggested, the skirt also helps keep lower edges from curling.

I hope this comment helps you in some manner.

What printer, bed, temps, material etc.? A little info would be very helpful.
