@polishmasterco: Layer lines occur because 3D printers build objects in slices, creating microscopic 'steps' rather than a smooth slope. The biggest challenge in removing them isn't the hardness of the plastic, but the heat. Dry sanding creates friction that melts the PLA, clogging your sandpaper. The secret? Wet Sanding. Water keeps the plastic cool, allowing the sandpaper to cut down the steps instantly. Want to learn more about achieving that mirror finish?
