How to Paint 3D Printed Terrain: A Quick, Table-Ready Method

If you want to know how to paint 3D printed terrain without losing a month of evenings to it, the answer is a short, repeatable routine: clean the piece, prime it, lay down a dark basecoat, drybrush up through two lighter shades, then pick out a few details and finish the base. That is the method we use on scenery headed for the table rather than the display cabinet, and it works on both resin and FDM prints. A ruined tower done this way takes an evening, not a weekend.

Everything below assumes you already have some scenery to work on. If you are still building a collection, our guide to 3D printed terrain in the UK covers what to buy, and the full terrain range is here.

Before you start: clean-up and layer lines

Give every piece a quick wash in warm soapy water and leave it to dry completely. It shifts dust and the grease from handling, which is what usually stops primer from sticking. Trim any leftover support nubs with a hobby knife or a sanding stick while you are at it.

FDM terrain needs one extra thought. Pieces such as the Diceverse Drowned Front Docks are printed in filament, so you will see fine horizontal layer lines. On weathered timber, rubble and stonework those lines mostly read as texture, and drybrushing can even help. On smooth surfaces like metal panels, a light sand before priming makes the finish cleaner. Resin pieces such as Artisan Guild's Ruins Scenery have far less visible layering and go straight to primer.

How do you prime 3D printed terrain?

Prime 3D printed terrain with a spray primer in two or three thin, quick passes rather than one heavy coat. Thin coats keep the surface detail sharp. A heavy coat pools in the recesses and softens exactly the brickwork and planking you want to show off.

A few habits make priming 3D printed terrain far more reliable:

• Spray somewhere dry and well ventilated, and keep the can moving. Cold, damp days are the usual cause of a grainy, frosted finish, so wait for a milder spell if you can.
• Follow the distance on the can's label, and work in short bursts from several angles so undercuts get covered.
• Let it cure fully before you put a brush near it. Painting onto tacky primer lifts it.

Pick a primer colour that does some of the work for you. A mid-grey such as Colour Forge Standard Grey suits stone, ruins and sci-fi industrial pieces. For wooden jetties, earthworks and trenches, a brown like Hyrax Brown gets you most of the way before a brush is involved. Both are 500ml matt spray primers, and the whole Colour Forge spray range is worth a look if you are planning a themed table. Our prepping and priming guide goes deeper on the miniature side.

How to paint 3D printed terrain: basecoat, drybrush, wash

This is the bit that makes scenery look finished, and it is also the quickest part. Treat it as a wargaming terrain tutorial in three passes.

1. Basecoat dark. If your primer is already the right base colour, skip this. Otherwise brush or spray a dark shade of your main colour over the whole piece. Don't worry about neatness. Terrain forgives a lot.

2. Drybrush up. Load a broad, soft brush with a lighter shade, wipe almost all of it off on kitchen roll, then flick the brush across the surface. Paint only catches on raised edges, so stonework, rivets and wood grain pop straight out. Go over it again with a lighter shade still, using less paint and a lighter touch. A domed goat-hair brush like the ones in this three-piece drybrush set covers big areas fast and won't mind the abuse. For stone, the Army Painter Warm Greys & White triad gives you a ready-made dark, mid and light step.

3. Wash the recesses. A thin brown or black wash run into the cracks and mortar lines adds depth and dirties up anything that looks too clean. If the drybrushing came out chalky, the wash pulls it back together. Some painters prefer to wash before the final light drybrush. Try both and see which you like on your own pieces.

Details and bases: finishing easy tabletop terrain

A handful of spot colours is enough to make easy tabletop terrain look deliberate. Pick out a few metal fittings, a door, some rope or a banner, and stop there. Three or four accents per piece look intentional. Twenty looks busy from across the table.

Bases tie a whole board together, so finish them the same way every time. Texture with sand, such as Base Ready Desert Sand and Stone, drybrush it with the colours you used on the building, then add patches of coarse flock where grass or moss would grow. The basing materials collection has tufts, scatter and pastes if you want more variety, and our basing techniques guide covers the methods. Match terrain bases to your miniature bases and the whole table reads as one place.

Scenery gets handled far more than miniatures do, so a coat of matt varnish once everything has dried will save you a lot of touch-ups later. If you want to see more of where our scenery comes from, both Diceverse and Artisan Guild show off their full ranges on their own pages.

Frequently asked questions

What primer is best for 3D printed terrain?

A matt spray primer applied in thin coats is the most practical choice for 3D printed terrain, because it covers large, textured pieces quickly. Choose the colour by the material you are painting: grey for stone and metal, brown for wood and earth, white if you want bright, light-coloured buildings.

Do you need to prime 3D printed terrain?

Yes, we recommend it. Primer gives acrylic paint something to grip, so it stops paint beading or rubbing off the edges when the terrain is picked up and moved during games.

Can you paint FDM terrain the same way as resin terrain?

Yes, the same clean, prime, basecoat, drybrush and wash routine works on both. The only difference is that FDM prints show layer lines, so smooth surfaces may need a light sand first, while textured stone and wood usually don't.

How long does it take to paint a piece of 3D printed terrain?

Painting time is mostly drying time. With primer, basecoat and wash all needing to dry, a mid-sized ruin usually takes one evening of actual brushwork spread across a day or two. Batch several pieces together and the whole table comes together much faster.

Pick one piece, keep the palette small and get it on the table. Once you have done one, the next five go a lot faster.
