The surfaces of my printed parts using ABS plastic look rough and uneven.
What methods can I use to achieve a smoother finish for my for 3D-printed objects?
Acetone can be used to smooth ABS.
Take note: acetone is dangerous to breathe in, so work in a well ventilated area. It is also flammable.
Warm acetone vapour bath using stove
This method involves suspending the model in a glass jar of boiling acetone that is heated up by a pot of boiling water.
- Attach the model to the lid of the jar with some string, keep the string short, so the model is close to the lid.
- Put a few centimetres of water in a pot
- Place a rag at the bottom of the pot (to keep the jar stable).
- Place the glass jar in the pot, on top of the rag.
- Place the pot on the stove and heat to 110°C.
- When the acetone is boiling place the dangling model into the jar.
- After a few seconds, remove the model.

Warm acetone vapour bath using printer bed
This method elevating the model in a glass jar of acetone that is heated up by the printer's heatbed.
- Find a non-soluble object that the 3D model can stand on.
- Put a teaspoon of acetone in jar.
- Place the jar on the heatbed and heat to 110°C.
- Place the stand into the jar.
- Place the model on the stand, the stand should not let the acetone touch the model.
- After a few minutes, remove the model.
