Comment on How do you Sand Coloured PETG without loosing the Colour? Are there any Methods to Preserve or Regain the Colour?

I’ve polished to a practically mirror shine with progressively finer and finer grit sandpaper. Took an eternity. Worked for the purple I was using, but it might not work for all colours.

I’ve also tried heating PETG with a butane lighter out of pure frustration. It does work, but the line between restoring the surface finish and deforming the print is very thin.

I see, thats quite interessting… I do wonder since my Main Concern are Flat Top Surfaces, if putting the rough Print surface on a Heated Surface of Sorts would do something simular? Thinking like a Heated Pan or Metal Sheet?

  I think a heat gun would probably work, as suggested elsewhere. A hot surface might transfer its texture to the print?
  
  Oh! I wonder if your printbed could get hot enough to do it?
  
  Otherwise, yeah, 220 -> 400 -> 600 -> 1000 -> 2000 -> 4000 -> 8000 -> 10000 grit might do it.

    Hmmm my Heatbed goes to 100°c and I do have a Smooth surface plate around… what do you think?
