Painting on 3d printed PLA?

[Desmo]

Have any of you painted on PLA? Will the paint stick to the plastic?
What paint should I use?

I've used Krylon, and RC Model paint with success

Both enamel and acrylic spray paint will work with PLA.

I have also used Tamiya TS paint on PLA with good results.



That being said, different brands of PLA use different colorants and additives which may impact how well paint will stick to it.

No problem painting PLA.



I suggest a filler primer, It does wonders for the gaps between layers. You can sand but you don't need to. Nice clean coverage of your top coat.

Brush painting with acrylic also works well.
