L'Antre du Tryphon
ABS juice makes the first layer of a print stick very well to the print bed. Put a small quantity of ABS juice on a paper towel and rub it gently on the printing bed. Making ABS juice is simple. In order to do so, you will need:
Cut the ABS filament in small pieces of 1 to 2 cm. Put 250 ml of acetone in the container. Put the filament into the container. Put the cap on and shake the bottle for a few seconds. Let it sit there overnight. The ABS will dissolve completely. Shake the bottle before using it. 250 ml is plenty for many prints.
