Well, I have painted the rest of the 3D printed deck equipment that I bought from Shapeways.com. All of the items you see in these photos have been designed by Greg (gjholmes77), who is a member here on modelwarships.
I will be detailing and painting the 40' and 50' personnel and utility boats next.
For the most part, painting is fairly straight forward with 3D printed stuff. I have used enamel paints, Tamiya paints, and some other acrylic paints. I haven't had too many issues with any of them. I think with enamel paints it seems like the drying time is a lot longer and the piece remains "tacky" for some time, but not always. I have read and also witnessed that this material if not fully cured and smooth can absorb a lot of paint. This usually happens where the "rougher" areas are. I have been experimenting with sealing with future floor wax. If you notice on the personnel boats that are the bare 3D printed material, I did some prepping and added several coats of future (made them shiny) to them to see if that might help aid in a smoother finish and keep the paint on the surface rather than being absorbed. I will let you know how it turns out.
I have added some links below where you can find all of these items if you wish.
