Can PLA Be Painted?
Painting workflow
- Sand: 120 to 240 grit to knock down layer lines
- Filler primer: auto body filler primer fills small gaps
- Wet sand: 400 to 800 grit between primer coats
- Base coat: spray or brush, thin coats
- Detail coats: acrylic for fine work, weathering washes for depth
- Seal: matte or gloss clear coat to protect the paint
Best PLA for painting
Matte PLA. The mineral-filled surface grips primer immediately and gives an even tooth for paint. Standard glossy PLA fights paint adhesion; silk PLA fights it more (smooth shiny surface).
Paint types that work
- Acrylic: hobby paint (Citadel, Vallejo, Army Painter), most common
- Enamel: durable, oil-based, longer dry time
- Spray paint: aerosol cans, faster for large parts
- Airbrush: thinned acrylic for premium finish
