Types of terrain STL files
Dungeon tiles & walls
Modular floor tiles, wall segments, doorways, corridors, and room corners. Usually square-grid (25mm/square) or hex. Many include OpenLOCK connectors.
Cave & cavern systems
Organic rocky floors, stalactite ceilings, underground rivers, and cave wall sections. Often sold as full cave-room sets or scatter caves.
City streets & buildings
Cobblestone streets, building facades, market stalls, alleyways, city walls, and tavern interiors for urban encounters and skirmish games.
Wilderness scatter
Trees, rocks, boulders, hedges, fences, fallen logs, and bushes. Lightweight FDM prints that dress up any outdoor encounter.
Fortifications & castles
Castle walls, towers, battlements, drawbridges, portcullises, and siege engines for high-fantasy and historical miniature games.
Scatter items & props
Barrels, crates, braziers, statues, fountains, torture racks, tavern tables, and market goods. Resin-optimised for fine surface detail.
FDM vs resin: which printer for terrain?
| Factor | FDM (Bambu, Prusa, Creality) | Resin (Elegoo, Anycubic) |
|---|---|---|
| Best for | Dungeon tiles, walls, large terrain pieces | Scatter items, statues, detailed props |
| Build volume | Large (250×250mm+) | Small (130×80mm typical) |
| Surface detail | Good (0.2mm layers visible) | Excellent (0.05mm layers) |
| Cost per print | Very low (~$0.02–0.10/g) | Higher (~$0.05–0.15/g) |
| Setup & cleanup | Minimal | IPA wash + UV cure needed |
| Supports | Rare (terrain is flat) | Usually required |
Most terrain creators design primarily for FDM and mark resin-optimised files clearly. If you own both, use FDM for bulk tile printing and resin for fine scatter items.
Modular terrain systems explained
OpenLOCK — the open standard
OpenLOCK is a free, open-source connector system published by Printosaurus. Tiles use a recessed bayonet slot that accepts small printed clip pieces. Any two creators who both follow the OpenLOCK spec produce tiles that physically connect. Clips are usually printed in flexible TPU filament or rigid PETG. Look for "OpenLOCK-compatible" in a listing's description.
Dragonlock — the locking-tab system
Dragonlock (Fat Dragon Games) uses interlocking tabs moulded into the tiles themselves — no separate clip pieces. Tiles click together firmly without tools and release cleanly when you pull them apart. This proprietary system offers quick setup and teardown at the table but is only compatible with Dragonlock-spec tiles from participating creators.
Standalone (no connector) — the simple choice
Many terrain creators design standalone tiles: flat-bottomed floor tiles and self-supporting wall pieces that sit on the table without any clip system. These are the easiest to print and mix-and-match from different creators. They rely on the table surface to hold them flat and are ideal if you store terrain flat in foam trays rather than building modular structures upward.
Painting 3D printed terrain
3D printed terrain paints the same as resin or plastic terrain kits. A typical workflow:
- 1. PrimeSpray primer (grey or black) seals the layer lines and gives paint a surface to grip. Rattlecan primer works perfectly on PLA and resin both.
- 2. Base coatApply your main colour with a large brush or airbrush. Stone: dark grey or brown. Wood: brown. Metal: black then drybrush silver.
- 3. DrybrushDrybrush a lighter shade over raised surfaces to pick out texture. This one step can transform plain grey terrain into convincing stone in minutes.
- 4. WashApply a dark wash (Citadel Nuln Oil, Army Painter Dark Tone) to deepen recesses and add shadow. Let it pool in crevices.
- 5. DetailsPick out details: moss (stippled green/brown), rust (orange-brown), blood stains, or freehand signage. Seal finished terrain with matte varnish to protect the paint.
What to check before buying a terrain STL file
Printer type compatibility. The listing should state whether the terrain is designed for FDM, resin, or both. FDM terrain avoids extreme overhangs. Resin terrain may have thin walls that crack in PLA.
Scale and grid size. Check that the tile grid matches your gaming system. D&D uses 1-inch squares (25mm); Warhammer uses different basing conventions. Some creators sell at 32mm scale, which prints slightly larger than 28mm sets.
Connector system. Standalone, OpenLOCK, Dragonlock, or proprietary clip. If you already own terrain from a specific system, buy tiles that match.
Polygon count and watertight mesh. Use the Proofly 3D viewer to spin the model and spot any holes or reversed normals before purchase. A watertight mesh slices cleanly; a non-watertight mesh may need repair in Meshmixer or Microsoft 3D Builder first.
Licence type. Personal-only licences prohibit selling physical prints. Commercial licences let you sell painted terrain at conventions, in local game stores, or via Etsy. Check the licence on each listing before purchasing for commercial use.

Terrain STL file FAQ
What scale should I use for tabletop terrain STL files?
Most tabletop terrain is designed for 28mm or 32mm heroic scale miniatures. A standard dungeon floor tile is 25mm per grid square (1 inch = 1 square), which means a 4×4 tile prints at 100×100mm. Warhammer 40K and Age of Sigmar terrain is calibrated for 28–32mm infantry models on 25mm or 32mm bases. Check the listing for the stated scale — most creators specify grid size and miniature compatibility. You can always scale terrain up or down in your slicer to match your preferred miniature scale.
Should I print terrain on an FDM or resin printer?
FDM printers (Bambu Lab, Prusa, Creality, Voron) are the best choice for terrain: large flat surfaces, dungeon walls, and modular tiles print quickly and cheaply in PLA or PETG. FDM layer lines are rarely visible on painted terrain and the larger build volume handles full-size dungeon room floors in one print. Resin printers excel for small detail items — statues, crates, chests, small scatter pieces where fine surface texture matters. Many terrain creators release separate STL versions optimised for FDM and for resin. Scenery packs marked 'FDM-optimised' usually avoid overhangs that require support removal.
What is OpenLOCK terrain and is it compatible with other systems?
OpenLOCK is a free open-source connector standard (published by Printosaurus / Þórðr) that lets modular terrain tiles clip together using a recessed bayonet locking mechanism. Tiles from different creators that both implement the OpenLOCK spec are compatible with each other. Other popular systems include Dragonlock (Fat Dragon Games) and Hirstarts-style pegs. When buying terrain STL files, check whether the creator specifies 'OpenLOCK-compatible', 'standalone (no connectors)', or a proprietary clip system. OpenLOCK tiles require printing separate clips in flexible filament (TPU) or a rigid clip variant the creator may supply.
How long does it take to 3D print a full dungeon room in terrain tiles?
A single 4×4 dungeon floor tile (100×100mm, 3–5mm thick) typically takes 1–2 hours on an FDM printer at 0.2mm layer height. A complete dungeon room — four floor tiles plus four walls — takes 8–12 hours of printing. With multiple printers or a large-format machine you can print a full adventure worth of terrain in a weekend. Wall sections (50×50mm, 25–30mm tall) take 45–90 minutes each. Terrain printing is well-suited to overnight batches: start a build plate full of tiles before bed and wake up to a finished room.
Can I sell painted terrain or physical prints made from terrain STL files?
This depends on the licence the creator attaches to each STL file. Proofly listings display the licence type prominently: Personal licence allows printing for your own use only; Commercial licence allows selling physical prints of the model; Extended Commercial allows larger-scale production. Always check the licence on each terrain file before selling physical prints. If you want to sell painted terrain commissions or at conventions, look specifically for STL files with a Commercial or Extended licence — many terrain creators offer these, sometimes at a higher price tier.
What types of terrain are available on Proofly?
Terrain STL files on Proofly cover a wide range of environments and styles: dungeon tiles and walls (stone, brick, hewn rock), cave systems and cavern floors, city streets and building facades, wilderness scatter (trees, rocks, hedges, fences), fantasy castles and fortifications, sci-fi corridors and space stations, desert ruins, jungle temples, and underwater environments. You will also find scatter items — barrels, crates, braziers, statues, market stalls — that dress up any terrain set. Use the 3D viewer to inspect surface detail and verify scale before purchase.
