: Finishing with Acetone vapour

Warning:- Using solvents like acetone can be very dangerous. Always carefully read the safety instructions. Don't do this if you don't know what you're doing! Acetone vapour is flamable, do this outside and away from any sparks, electrical equipment.

The goal is to use acetone vapor to eat away at your model, leaving it with a glossy, injection moulded look and feel.

To do this you will need:
To process the part you will need to do the following:

I have been using a rice cooker with a modified steam tray. The rice cooker heats up and evaporates the acetone which coats the model, melting the outer layers.

I cut out the middle of the steam tray and lowered it into the cooker so that larger parts can be put in the machine.

This whole process take about 3-5 minutes, although if you leave it for too long the model will start to bubble and give an undesired effect.
You will also notice that the colour changes to be a bit lighter than the initial print, this usually happens when the part is drying after the process.

(Regular print on the left, Acetone treatment good in the middle, on the right was left in the vapor for too long)


These are some other prints with the process applied.

This one i put in for a shorter length of time so it could retain some of the texture from the print.

It goes without saying that you should not attempt this without the proper safety equipment, i wear a ventilation mask, safety glasses and gloves while i perform this process and always do so outside. Be very careful not to spill any acetone around the rice cooker or power outlet.

These are some examples of colours i have tested so far. All the swatches are in the order of  regular print, good vapor, bad vapor. (sorry for some of the dodgy photos, i need to buy some different coloured backdrops at some point). These are all colours available from the 3D Printing Systems Store.

I've seen people on the interweb using a deep fryer (chip cooker).
One teaspoon of acetone in the bowl.
Model into the mesh basket and into the bowl.
Glass lid goes on.
Low power for 30 seconds.
Bingo.

Get a cheapo deep fryer from Aldi and remember to do it outside and down-wind.

i simply 'paint' the acetone on, quickly, with a medium artist brush, used specifically for this.
very quick, and can flood or dribble on. Just the original container and a clean brush, simple.
Works for me
cheers
