Printing HIPS is perfect for support material on all dual extruding 3D printers. Lemonesol is a special liquid, which dissolves HIPS filament without any effect on the quality of the ABS/PLA print.
Lemonesol is a biodegradable material, which is made of oil from the peel of citrus fruits. Lemonesol is not intended for internal and needs to be worked with in a well-ventilated room.
How to use Lemonesol: Simply submerge your model in the liquid for 2 or more hours. Your HIPS filament will become slimy and will eventually dissolve; your ABS model will remain unharmed
