PolySmooth is a unique material designed to be smoothed by isopropyl alcohol. This allows you to remove the layer lines. The PolySmooth Transparent is a little yellow untreated. It also needs more heat. I recommend starting with your PLA settings and adding 10 degrees to your hot end. Polymaker sells filament in 750g sizes on plastic spools.



To smooth this filament Polymaker recommends the Polysher machine. I tried using a spray bottle atomizer for the Marvin in the middle. It required a large amount of spray. The Marvin to the far right used a more traditional smoothing technique. The Marvin was placed on a platform in a sealed container with an alcohol soaked paper towel lining the edge of the container. It took 7 hours in the container but it looks so nice, smooth, and shiny. Its really hard to capture in photos.
