Blogger Pat has successfully printed parts from ABS plastic on his 3D printer which has a maximum bed temperature of just 60C, instead of the 100C recommended for ABS.
He did so by printing a single layer of PLA onto the bed, and then switching to ABS (which the printer saw as PETG) for the rest of the print.
The PLA layer readily separates from the ABS part afterwards, leaving a good finish.
This technique could allow people with budget 3D printers to successfully print ABS components, and could be useful in situations where smaller items are less prone to warping.
Other hacks to prevent warping include printing with an enclosed printer, and cover the bed with tape, glue or a specialised surface.
