Do you need to prime PLA before painting?

We found that PLA and PETG were by far the easiest 3D printing materials to coat and acrylics had excellent adhesion without prior priming. There was no noticeable difference between High Flow and Fluid paint films on any print.

What paint is best for PLA?

acrylic paints
MakerBot PLA Filament is easily painted with cellulose spray paints or oil paints, though acrylic paints are considered to be the best choice. For optimal safety, use child-friendly paints.

What glue is best for PLA?

Cyanoacrylate glue
Cyanoacrylate glue is usually the best choice when glueing PLA parts. Any brand will work: Gorilla Glue, Loctite, SuperGlue, extra-strong glue or any instant glue. I prefer it on small tubes so it won’t spoil if I don’t use it in a while.

Put on your safety gear Before you do anything, make sure to put on your eye protection and a respiratory mask.

What kind of primer to use on 3D printed models?

For smoothing out the build-lines in 3D printed models, you can use a sandable 2-in-1 primer and filler. A primer and filler is great for 3D prints and large models. After these primers dry, you can sand the automotive primer even out the surface in preparation for paint.

What kind of primer to use on plastic miniatures?

The best primer for painting miniatures depends on the surface material. Some primers work best on plastic, whereas other primers work best on metals.
