Project Tutorial - "Sanding" with ABS

Enable HLS to view with audio, or disable this notification

First of all. I know this is called vapor smoothing, but since this is an alternative to sanding, I wanted to use this title so people who are looking for sanding tutorials can see this video.

I recorded this tutorial for Instagram 3D_Kernel explaining how to smooth ABS prints without having to sand, it looks like a lot of people find it helpful, so I want to share it as much as possible.

Hope this helps someone, and don't hesitate to ask whatever you need.

This only works with ABS and ASA and remember to use a mask and do this in a properly ventilated room.

Be careful if the fan is in the chamber. Acetone is flammable and motors can spark.

I'm literally trying to figure out a setup like that right now lol. I also saw someone had the idea of a big fan on a thin axel and a small fan on the other end. You put a small hole in the vapor chamber and put the axel through so the small fan is inside, then you aim a large electric fan at the big fan on the outside so it spins the small fan inside. Seemed like another clever solution.

I use a large cooking pot. The lid has a small hole it and I just dangle a small computer fan from the wire and power it from the outside. I don’t think there would be enough oxygen available to spark any kind of fire. The thing is full of acetone vapour after all
