Painting 3D Prints

Recommended Posts

The prints I make are resin based. Has anyone tried painting this type of print?

I have been told water based but have not yet tried it.

thanks

Often a spray primer first works well, most paint designed for models (plastic or pewter) seems to do fine. If it has any ridging which is more common in the FDM plastic method than with resin, I generally use a little spackle first, then sand, prime and paint.

A nice clear coat to finish it off usually gives it a nice look. I'll try to find some images of surfaces after painting.

I've generally used a spray primer too. I tend to go for Primer Filler variety which will fill small imperfections. Ideally something that you can paint on top of with acrylic paints. You can get some great results.

Does this mean it will be dissolved by solvents ?

In studies, when building "real" models from Styrofoam, Styropor and similar,
there where special spray paints that don't destroy these materials in our
model building shops ....

All water based lacquers should be fine (like Acrylic lacquer ?)

Primer will help mostly but no guarantee if you use very aggressive paints with dissolvents.
There are also special spray paints for plastics.
(Something similar to this : https://www.amazon.co.uk/Lacquer-Varnish-Water-Based-Styrofoam-Colourless/dp/B00J4N4BOK)

 

It depends, Carbon is also resin based.
And Carbon bicylcle frames normally withstand even 2c varnishes.
