Yes I've done this. Just make sure to do it in layers and the layers must be thin, or they will get too hot and bubble. You're essentially just manually 3D printing your own additional layers. Also light top colors should have a light base to add to.

Just wondering: has anyone tried putting 3D resin (of one colour) with a paintbrush or other tool on top of a resin 3D print in another colour to create a two tone resin 3D print?

I have several 3D designed items that would benefit from having two colours on the surface.

I do this quite often. I 3d print certain objects and paint and clear coat with UV resin. works fairly well. I was trying to cure something about 3mms thick in black and it never cured. Made a mess, but I tried again and curing a few layers at a time worked.

I paint over mine with uv resin. Is ok if you like high gloss.

I am looking for a gift for a very active 3D skeletal printing friend. He works hard to use the three printers he has for good, and always makes helpful things for people. He's sent hundreds of parts for face shields to our local medical centers back when PPE was incredibly difficult to come by, and I thought that was pretty awesome.

Makers are incredibly difficult to buy gifts for, especially if you don't know them well...

this post is in the 'MSLA' section of the forum, whilst Most PPE makers probably would have used 'FDM' Printers...

probably the safest item to buy that is 3D print related, is some material of the type the person uses

For MSLA printing you might consider (resin Printing)

For FDM printing (Fused filament printing) you may consider
https://shop.prusa3d.com/en/16-filament

but it's probably best to ask the person concerned...

and resin / filament are probably more locally available.

I also think that there is something we miss.
I didn't wash the painted parts (of course not) which might explain the surface shine.
I assume that the washing with ethanol normally washes away all the little bits or resin that weren't cured, whereas now they stay on the surface and get cured in one smooth sheet.

Not 100% sure I understand what the problem is here but it is known that oxygen in the air suppresses UV curing adhesives and may be having an effect here. See here: https://www.instructables.com/community/Tips-and-tricks-for-UV-curing-blue-resin-and-coati/

Was it supposed to be Matte? Does it appear matte on other surfaces.

Yes properly printed objects will have a matte finish once properly cured. If you see shiny areas on your print it is an indication that you did not get it properly clean prior to doing the final cure. Translucent/clear resins can be polished to be clear, but when they come out of curing they will have a cloudy/matte look.

So my assumption here is that there is something about the light from the SL1 and CW1 or about the process (reacting with the larger mass of resin in the tank? something to do with curing very thin layers at a time?) that is not accounted for in this "painting" and curing process.
