Or contact DAG as he generously shares the knowledge he has. Leo
Thanks for your answer. I have been in the 3D printing hobby for over six years ;-). Acetone mist is used to smooth out ABS prints. It only works with this type of plastic. Problem with ABS is that its highly toxic when printing, has a nasty tendancy to warp and the Acetone smoothing process is not only highly flammable but toxic too. Something you do not want to do very often as a hobbyist. Apart from that, it is an enviromental desaster in production and recycling.

I print with a material called DBP. Its 100% eco friendly, tough as nails and has a very high "glass-temperature*" of 100C. (PLA is somewhere around 55-60C, ABS 90-100). The only two downsides are 1. its expensive and 2. it cant be smoothed with ABS mist.

*The temperature the material becomes soft
