Will it fit my miniatures?

The design is scaled for 28–32 mm miniatures. Set the final size in Print Export; a doorway of about 30 mm is a good reference.

Can I print it on an FDM printer?

Yes. Terrain prints well on FDM at 0.12–0.2 mm layers.

Can I make a matching set?

Yes. Use the same material words for every piece, like "mossy grey stone", and they'll look like one set.

Made with this template

The card in the corner shows what went in.

Goblin campsite terrain — A goblin campsite with a tent, a campfire and crates

Graveyard terrain — A mossy graveyard corner with leaning tombstones and a dead tree

Wooden dock terrain — A wooden dock with barrels and a small rowboat

Each example is an actual run of this template at Standard quality, made from a typed idea or a sketch.

Behind the scenes

How this template works

Terrain has to stand on a table and survive dice rolls, so the template designs everything on one solid base first, then builds the 3D model.

Do it yourself for more control

Make a matching set by describing pieces with the same material, like "grey stone ruins".
Use Ultra mesh quality for crisper bricks and planks.
Scale it in Print Export so a door is about 30 mm tall for 28 mm miniatures.

What is 3D AI Studio?

3D AI Studio is a web app that makes 3D models, images and sounds with AI. It runs in your browser, so there is nothing to install.

A template is a saved recipe. It runs a fixed set of AI tools with settings we've already tested, so all you add is a photo or a sentence.

How to describe it

Describe one piece, not a whole map: a tower, a well, a campsite.
Mention the material and condition: mossy, ruined, burnt.
FDM is fine for terrain; resin brings out fine stonework.

Good to know: Pieces are solid; interiors and removable roofs need to be modelled separately.

Chat brief · Tabletop Terrain

Use the 3D AI Studio MCP to run the "Tabletop Terrain" template (https://www.3daistudio.com/templates/3d-printed-terrain) for me.

My idea: A ruined stone watchtower with a broken staircase
Style: Grey primer
Base shape: Irregular

Follow these steps in order. The prompts and settings are the template's own, so use them word for word and only put my idea where it says {MY IDEA}.

1. Design the terrain
Call generate_image_nano_2_1 with aspect_ratio "1:1", resolution "1K", output_format "png" and this prompt:
"""
Terrain piece: {MY IDEA}. A single tabletop wargaming terrain piece sized for 28-32 mm miniatures, built on one flat irregular base with a gently textured ground, everything attached to the base with no floating parts, sturdy walls and props with no paper-thin details, open enough that miniatures can stand on or around it. The entire piece visible with generous empty margin, centered, three-quarter view from above. Isolated on a seamless pure white (#FFFFFF) background, soft even studio lighting, no shadows on the background, no miniatures, no text. Material: unpainted, uniform matte grey primer, like freshly printed resin terrain.
"""
If I want to start from a sketch or reference image instead, call upload_image so I can hand it over, then call edit_image_gpt with the upload in images, quality "low", output_format "png" and this prompt:
"""
Turn the scene in the reference sketch into a tabletop terrain piece, keeping its layout and key features. A single tabletop wargaming terrain piece sized for 28-32 mm miniatures, built on one flat irregular base with a gently textured ground, everything attached to the base with no floating parts, sturdy walls and props with no paper-thin details, open enough that miniatures can stand on or around it. The entire piece visible with generous empty margin, centered, three-quarter view from above. Isolated on a seamless pure white (#FFFFFF) background, soft even studio lighting, no shadows on the background, no miniatures, no text. Material: unpainted, uniform matte grey primer, like freshly printed resin terrain.
"""

2. Build the 3D model
Call generate_prism_3_1 with the task_id of the image from step 1 in images, texture_model "3.5", texture_quality "fast", geometry_quality "standard", pbr false.

3. Export
Export it for printing: call convert_model on the 3D model with output_format "3mf" (or "stl" if I ask for it), plus max_size and unit "cm" if I gave you a print size.

After each generation call, keep polling get_generation with its task_id until it completes, then show me the result with show_generation before you start the next step.
