Saying acrylonitrile butadiene styrene is a mouthful, but ABS is a well-tested thermoplastic used for 3D Printing filament. It has a high melting point of 105°C/221°F. It has high impact resistance and lasts long. It’s smooth finish quality is ideal for print areas that need to run smoothly and not bind up. ABS is acetone soluble, so you can post finish and smooth it even more. A printer with a heated build plate works best. We personally don’t use ABS because we don’t want the smell of the fumes in our home office. Make sure you have a well-ventilated area.
