barkest Posted September 6, 2016 Share Posted September 6, 2016 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 Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted September 6, 2016 Vectorworks, Inc Employee Share Posted September 6, 2016 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. 1 Quote Link to comment
Kevin McAllister Posted September 6, 2016 Share Posted September 6, 2016 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. Kevin Quote Link to comment

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 ....

barkest Posted September 6, 2016 Author Share Posted September 6, 2016 Thank you yes it will be disolved by solvents so I am unsure about the spray paint primer? Quote Link to comment
zoomer Posted September 6, 2016 Share Posted September 6, 2016 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. 1 Quote Link to comment

rjtiedeman Posted April 22, 2020 Share Posted April 22, 2020 (edited) I have been ordering Stereolithography (ultraviolet laser resin) for years and have used (Duple-Color) high build auto touch up primer and matching automotive touch up paint. DO NOT mix paint types. Bondo Glazing and Spot Putty works well to fill surface ridges. I have also had the Stereolithography vendor custom paint the parts. Finishing ultraviolet laser resin Stereolithography is a labor of love. I now try to get the project to cover the finishing cost. Test any paint first. We had an issue with a team member using standard Krylon primer then using Krylon for plastic we ended up with wrinkled mess. Test First on small parts. No guarantee you have to test since resins and paints vary. Edited April 22, 2020 by rjtiedeman Quote Link to comment
