ABS is one of the most popular 3D printing materials in the world because it is strong and easy to print. It's a durable plastic that can be used for prototypes or functional / end use 3D printed parts.
How sturdy is ABS? LulzBot 3D printers use parts printed with ABS. Therefore we rely not only on our machines to print reliably to make more of them, we also need the ABS parts themselves to last under heavy use. With our cluster of over 145 LulzBot 3D printers being used nearly every day, suffice to say ABS has passed the test.
ABS prints can be sanded or smoothed using an advanced technique with acetone. Experienced users have found that the visible layers on a print can be significantly reduced with an acetone vapor bath (a process in which the ABS print is exposed to warm acetone vapor for a brief period of time). With this technique, you can have ABS parts that are glossy and smooth. This process may also strengthen the parts themselves by binding the printed layers together.
