Custom DnD Miniatures: Create Custom Dungeons and Dragons Miniatures with AI

You've spent hours building your character. You know their backstory, their flaws, the exact way they hold their weapon. Then you go looking for a mini and the best you can find is "vaguely humanoid figure with sword." It's the eternal D&D problem: your character is specific, but the mini options are not.

Hero Forge helps, but you're still limited to their parts library, and a printed mini runs $20-65. Commissioning a sculptor gets you exactly what you want for $50-200+, but you're waiting weeks and your campaign might be over by then. AI 3D generation gives you a third option: take your character art (or just describe your character), get a full 3D model in under two minutes for $1-5, then order a print shipped to your door. We've seen DMs generate minis for entire encounter tables in a single evening.

Path 1: Turn Your Character Art Into a Mini

If you already have character art, whether it's a commission, something from a character creator tool, AI-generated art, or even a decent sketch, this is the fastest route. Upload the image to Model Spawner, pick an AI model, and you'll have a 3D mesh you can rotate and inspect in about 90 seconds.

The AI uses the actual visual details from your art to build the 3D shape. That means your tiefling's specific horn style, your paladin's exact armor design, your warlock's creepy patron-gifted staff, all of it carries over. It's not matching against a parts library. It's building geometry from what it sees.

A few things that make for better results:

• Full body, head to feet. The AI needs to see the whole character. Bust portraits and waist-up crops will produce incomplete geometry below the cutoff.
• Standing or neutral pose. A heroic stance with arms visible works great. Dynamic action poses where limbs cross the body or extend at extreme angles tend to produce messy geometry.
• Clean background. White, transparent, or simple gradients. If your art has a detailed scene behind the character, crop it or drop out the background first.
• Weapons and gear clearly visible. Swords, shields, cloaks, and armor details should be distinct and not overlapping the body too much. The AI models anything it can see.
• Any art style works. Painterly, anime, realistic, stylized. The AI handles all of them. Extremely abstract or chibi proportions may produce unexpected results, but standard fantasy art styles convert well.

Path 2: Describe Your Character, Skip the Art

No character art? No problem. Model Spawner can generate an image from a text description first, then convert that image to 3D. It's a two-step process (text to image to 3D) but the platform handles both steps automatically.

The key here is writing a prompt that gives the AI enough to work with. Vague prompts produce generic results. Specific prompts produce minis that actually look like your character. Here's a structure that works well:

Formula: [race] [class] [key physical details] [equipment] [pose] [style keyword]

Some example prompts that produce good results:

• "A female dwarf paladin in scratched full plate armor, holding a warhammer in one hand and a battered kite shield in the other, red braided beard, standing heroic pose, fantasy miniature style"
• "A tiefling warlock with curved ram horns and a long tail, wearing tattered dark robes with glowing purple runes, holding a pact blade, standing pose, D&D character art"
• "A half-orc barbarian with a mohawk and tribal face paint, bare-chested with fur bracers, wielding a jagged greataxe, aggressive stance, tabletop miniature"
• "An elderly human wizard with a long white beard, wearing star-patterned blue robes, holding a gnarled wooden staff topped with a crystal, standing relaxed pose, fantasy figurine"
• "A kenku rogue in dark leather armor with a hooded cloak, daggers strapped to both thighs, crow-like head with black feathers, crouched ready stance, D&D miniature style"
• "A dragonborn cleric in chain mail with a sun symbol on the chest plate, scales are bronze-colored, carrying a mace and a holy book, standing stoic pose, fantasy miniature"

Notice the pattern: every prompt includes physical traits specific to that character, not just race and class. The mohawk on the barbarian, the star-patterned robes on the wizard, the battered shield on the paladin. Those details are what make the result feel like your character instead of a stock fantasy figure.

One useful trick: adding "miniature", "figurine", or "tabletop" to your prompt tends to produce images with compact, printable proportions. Without those keywords, the AI sometimes generates sprawling action scenes that don't translate well to a 3D model.

Picking the Right AI Model

This matters more than you might think. At 28mm scale, every surface feature gets compressed into a tiny area. What you care about is geometric detail, the actual shape of the mesh, not texture quality. Textures look great on screen but they don't show up on a resin print. Armor rivets, facial features, weapon edges: those need to be in the geometry itself.

For D&D minis specifically, we recommend Hyper3D Rodin or Meshy v6. Both produce dense, detailed mesh geometry that holds up at small scales. TRELLIS.2 is also solid and a bit cheaper. Hunyuan3D is the budget pick if you're generating a whole session's worth of NPCs and monsters and want to keep costs low.

Printing at Tabletop Scale

Resin printing is the only real option for D&D minis. FDM printers can't resolve facial features, fingers, or thin weapons at 28mm scale. Resin printers operate at 0.05mm layer height and 35-50 micron XY resolution, which is fine enough to capture the details that make a mini recognizable across the table.

Standard tabletop scales for reference:

In your slicer, scale the model so the figure measures about 33-35mm from base to top of head. That's standard 28mm heroic scale (the "28mm" is base to eye level, and the slightly exaggerated proportions are intentional for readability at table distance).

Post-Print: Supports, Basing, and Paint

• Add a base before printing. AI-generated models rarely have a flat bottom. Add a round 25mm base in Blender, Meshmixer, or your slicer. This also makes the mini fit standard D&D grid squares.
• Angle your supports. Tilt the mini about 30 degrees on the build plate and use light supports. This keeps support marks off the face and front of the figure where they'd be most visible.
• Wash and cure properly. IPA wash for 2-3 minutes, UV cure for 3-5 minutes. Skip this and the resin stays tacky and fragile.
• Prime before you paint. A thin coat of grey primer (or zenithal black-to-white if you want to get fancy) gives acrylic paint something to grip. Paint directly on bare resin and it'll chip off.

What It All Costs

Here's the full picture, because cost matters when you're outfitting a whole party (or a whole encounter):

To put it concretely: a party of 5 custom digital files on Model Spawner costs $5-25 total. That's comparable to a single Hero Forge digital file at $8. Need them printed? Order directly from Model Spawner — pick the size, and we ship it to your door. Even with printed minis at $25-60 each, you're getting a fully custom character that matches your exact art, not a template approximation.
