3Polymaker Polylite ABSPolyLite ABS with a datasheet. The catalog stores a nozzle of 230–260 °C (446–500 °F) and a bed of 90–110 °C (194–230 °F). This is the acetone side of the consensus. The sheet was not re-read for a smoothing recipe.ABS

4Polymaker Polylite ASAPolyLite ASA with a datasheet. The catalog stores a nozzle of 235–260 °C (455–500 °F) and a bed of 90–110 °C (194–230 °F). ASA is named with ABS for vapor smoothing. Outdoor use of ASA is a different page.ASA

Pick the finish before you pick the grit. The consensus has two paths, and they are different polymers.

PLA, then primer

Sand and paint PLA. PolyLite PLA and Prusament PLA are ordinary PLA rows with nozzle ranges, which is what you want under filler primer. The consensus names filler primer. It does not name a brand or a grit sequence, so this page does not either.

Cosplay and miniatures are the usual reasons to paint. Cosplay and miniatures choose the filament for the object. This page only covers the finish.

ABS and ASA, then acetone

PolyLite ABS stores 230–260 °C (446–500 °F) and a bed of 90–110 °C (194–230 °F). PolyLite ASA stores 235–260 °C (455–500 °F) and the same bed band. The consensus says both can be acetone vapor-smoothed.

Acetone is flammable. Do not treat a forum habit as a measured process. This batch does not include a time, a liquid volume, or a safe container, and this page will not add them. If the part also has to live outside, ASA’s weather note is on outdoor filament, not in the vapor.

Printer fit

A bed range of 90–110 °C (194–230 °F) does not fully fit a 100 °C (212 °F) bed. The P1S stores 100 °C (212 °F). Print inside the overlap, or pick a printer whose maximum covers the row, before you spend time sanding a warp.

Pros and cons

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.

Printer considerations

Printer limits

What the community says

The consensus is that PLA sands and paints well with filler primer, and that ABS and ASA can be acetone vapor-smoothed.

Questions

Does matte PLA sand better than plain PLA?

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.

Can I acetone-smooth PLA?

No. The consensus gives acetone vapor to ABS and ASA. PLA is the primer path.
