# ABS (Acrylonitrile Butadiene Styrene)
- Very common in consumer injection-molded parts.
+| Pros | Cons |

+| - Melts in acetone, acetone vapor smoothing can be used to improve surface finish
- Prints fairly quickly
- Very high toughness relative to PLA or PETG
- High temperature resistance
- UV resistant | - Very high warpage
- Smells horrid and outputs toxic fumes when printing |
+# ASA (Acrylonitrile Styrene Acrylate)
+Chemically similar to ABS, just better.
+| Pros | Cons |
+| ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------ |
+| - Very high temp resistance (past 100C)
- Very high UV resistance
- Matte surface finish
- Prints *very quickly*
- Greatly reduced warping compared to ABS | - Equally bad fumes as ABS
- Still somewhat difficult to print. |
+# HIPS (High Impact Polystyrene)
+Similar to ABS, but softer, waxier, and more flexible.
