No matter how good your FDM 3D printer is, you will always have the small ridges throughout the print. Reprapers have figured out an easy way to smooth out ABS 3D printed parts. By putting 3D printed parts in a glass jar filled with 3-4mm deep acetone on a heated build plate, Acetone vapor will form in the jar and react with the 3D printed object smoothing out those layers.

You can do it at home with some simple items, glass jar, RepRap's heated build plate, some aluminum foil, a hanger to bend into a hook to get the parts out etc. Based on a similar idea, Keith has come up with a completely sealed acetone vapor chamber device, a 3D Print Finisher.

"I came across many blogs that instructed people to place their object into a pot of acetone and heat it using a stove top or printer bed. I found out that: 1) placing a plastic object directly into acetone can quickly melt through the plastic, and 2) heating acetone vapors on a printer bed can seriously damage a 3D printer. I decided that there must be a more efficient and safer way of doing this, so I built the 3D Print Finisher." writes Keith.

Keith's 3D Print Finisher is very simple to use. Add a small amount of acetone into the heating pan, place the object onto the removable bed, turn it on. The leak proof steel frame allows the vapor to remain inside of the chamber. The front of the vapor chamber has a glass window so you can watch your 3D printed part become smooth. It takes an average of 3 minutes to finish 3D printed objects.

A fully assembled 3D Print Finisher costs $175 on Indiegogo, you can check it out here.

Try a presto brand deep dryer, same result, 1/8 the cost

All the instructions _I_ saw suggested a platform so you're not dipping your part in liquid acetone.

It is nice, but what safety measures are been taken? When the acetone vapours you practically have a bomb. It could be the case that it ignites once you open the door and let enough oxigen get in.
