I got a spool of white Polymaker PolySmooth filament from Amazon today. I printed a test cube and it looked good. I printed the 3D Benchy boat and I think it looked good. I printed a car door which required supports and I think there is under-extrusion on the surface where supports were attached to. The supports were easy to remove. I printed the small gears for an automatic transmission and they looked good. I'm in the process of printing the P1 carrier - P2 ring gear part. I hope that the part looks good. I didn't buy the machine for smoothing the prints.
