  "useCaseLabel": "Finishing",
  "updated": "2026-10-15",
  "shortAnswer": "PLA is the easy sand-and-paint filament when you use filler primer. ABS and ASA are the filaments this consensus vapor-smooths with acetone. Acetone is flammable, so that line is a material choice, not a workshop procedure.",
  "recommendedMaterials": [
    "pla",
    "abs",
    "asa"
  ],
  "printerConsiderations": [
    "Filler primer is a paint product, not a filament. There is no primer SKU in the catalog.",
    "ABS and ASA beds of 90–110 °C (194–230 °F) only partly fit a printer whose bed maximum is 100 °C (212 °F), such as the P1S. Check the printer page before you print a part you plan to smooth.",
    "Acetone vapor and liquid acetone are flammable. This consensus names the method. It does not list a time, a volume, or a container."
  ],
  "pros": [
    "The split is clear: PLA plus filler primer, or ABS and ASA with acetone vapor.",
    "The ranked rows are ordinary PLA, ABS, and ASA with stored nozzle ranges."
  ],
  "cons": [
    "No row stores a sanding grit, a primer brand, or an acetone time. Those are not filament fields.",
    "Vapor smoothing changes dimensions. The consensus does not say by how much."
  ],
  "community": "The consensus is that PLA sands and paints well with filler primer, and that ABS and ASA can be acetone vapor-smoothed.",

    {
      "q": "Does matte PLA sand better than plain PLA?",
      "a": "This consensus says PLA, with filler primer. It does not split matte from glossy. Matte is a surface question on its own page, and the bank for that page did not include a consensus."
    },
    {
      "q": "Can I acetone-smooth PLA?",
      "a": "No. The consensus gives acetone vapor to ABS and ASA. PLA is the primer path."
