First time trying to paint a thoroughly weathered/rusty piece, and also first time trying to paint 3D printed terrain.

Printed with a 0.2mm layer height, it was surprisingly annoying to paint compared to regular cast HIPS pieces. Washes are completely useless, or at least behave very differently, due to capillary effect of the layer lines.

I think I went a little too heavy with the rust orange color so it lost some definition. It looks a little more defined IRL than the photo shows.

If you print in ABS or ASA you can use acetone to vapor smooth the print. Then you'll get a smooth finish. Its a balancing act between smoothing layer lines and losing print detail though.

Also those are admittedly more difficult plastics to print than something like PLA.

    Yeah I probably could try printing it in ASA and smoothing it, just to see if the result is better. But honestly for terrain I would say the layer lines are not really an issue from a visual aspect, mostly just that I need to approach applying the paint slightly differently.

    I print almost exclusively in PLA and I use sandable filler primer, and sand a bit on large faces. It isn't as smooth as vapor smoothing in abs, but it does quite a bit to fill in some gaps. Not perfect, and obviously easier on prints with larger flat spots, but I have used it on some 5in figures.
