Comment on 3D Print ABS Without A Screaming Hot Bed

No one answered so I will:

Have an enclosed printer! You won’t be able to print anything larger than a couple of cm otherwise. Also make sure to not have air gaps, any cold air getting in can potentially lift up a corner.

You need a good first layer, even more so than with PLA. Have it squish a little more so that it sticks to the build plate like crazy.

Preheat your chamber passively with the bed. With my enclosed Ender 3 I did 10 minutes before large prints.

High bed temps: you might get away with 90°C at the lowest but 100°C is recommended.

When a print starts to lift off the build plate there’s no fixing it. Either you’re fine with the warp (and some squished layers/deformation) or you have to restart the print. No way to sugar-coat this.

Turn down part cooling as much as your overhangs allow, though with a hot enough chamber you might get away with “a lot” of cooling.

Print with brim or adhesion tabs! Mind the geometry of your part: models with tall walls will tend to warp more.

Tl;dr: printing ABS can be cruel, but it rewards you with strong, light parts that stay in shape even at high ambient temps like a car interior.
