In order to get a very smooth surface for my wax model I have tried to use a machine called Polysher by PolyMaker (click here). This little machine is simply using alcohol-dust / fog to evenly distribute a thin layer of alcohol on the model to treat the surface and make it more smooth. You can see it in action in the following short video. I have used pure (99.9%) isopropanol for 30 minutes. The result is surprisingly good! I can’t feel any printing / layer structure on the model anymore when touching it. This should improve the quality of the cast very much. I am not sure yet how much it changes the model when it comes to details but in case of the mouthpiece it should not matter too much. For delicate rings that might be different.
