Painting FDM Terrain - Overcoming the limitations of FDM prints
I've been resin 3D printing since 2016 and have learned an awful lot since then - in fact I consider myself to be something of an expert when it comes to getting great quality resin prints. And becasue I love miniatures so much, including painting them, the surface quality issues present in FDM prints have historically put me off wanting to go near them. About a month ago, I ended up pulling the trigger on an FDM printer purchase so I have something that I can use for testing and also making larger models. I thought I'd test my new printer out by making some of the terrain elevations (kind of like hills but in a grid based system). Long story short, I had no idea what I was doing so I set the layer height to as low as I could possibly go and made sure I turned on the ironing setting on all top surfaces to try to get rid of the horrible stepped surfaces that are typical of FDM. Despite my inexperience, the prints were a relative success, with only a few minor flaws. Now to paint them and record it all for your viewing pleasure! I'd already digitally painted one of these hills in zbrush so I had an idea of what I was aiming to achieve, but normally I'd do it with glazes and lots of layering, and a bit of drybrushing. None of these felt like viable options if I wanted to disguise or overcome the layer lines in the print so I needed to get creative. I decided to use a thick acrylic paint called Raw Umber from Castle Art Supplies - I think it was purchased from The Works and it wasn't expensive. Colour wise its a warm, mid-dark brown colour edging towards a milk chocolate type colour. I grabbed the biggest, scabbiest brush I own which is my old Citadel tank brush from the early-mid 2000s and I roughly stippled the thick paint all over, trying not to spread it out too thin. I had to leave it to let it dry for a while, and when I came back to resume, I realised that I'd not saved the footage of that first part of the paint job! Then I moved on to overbrushing/drybrushing. I did this in 4 phases:
