Finishing Filament 3D printed parts
- Wet-Sand PLA: PLA gets gummy from the heat of sanding soWhen post-processing PLA, it’s better to use wet sanding. Without water, you'll quickly start heating the plastic by friction, which will cause it to soften and make it hard to keep sanding.
- Filling layer lines and small gaps: XTC-3D or Bondo Putty
- Post-processing ABS parts: Filling gaps, sanding, priming, and painting ABS

- Shaving PLA prints with a card scraper for smooth surface finish - not recommended if you need dimensional accuracy
