People are often asking in comments how I print ABS on open frame 3D printers. For many prints, producing them in ABS is just a matter of upping the bed and nozzle temps and turning off the cooling fan. Other models, however, are destined to failure.

In this guide, I explore ABS printing successes and failures, and explain why ABS can be so difficult to print using some custom animations.

Summary:
-ABS needs 240+ for nozzle and 100 for bed.
-Fan to be turned off except for bridging, etc.
-Shrinkage occurs on thick/solid objects due to the uneven cooling causing the cooler areas to contract.
-This results in a lifted base and/or splitting between layers.
-The best way to overcome this is to raise ambient temps with an enclosure.
-Otherwise you are limited to printing models with thin or narrow sections.
-ABS is mainly useful for prints that need to withstand higher temperatures.
-ABS can be acetone smoothed!
-ABS releases potentially harmful particles into the air where PLA does not.
-PETG is a good substitute for ABS.
