Frequently Asked Questions

BlastMini 3D is a leading AI 3D miniature generator purpose-built for Dungeons & Dragons and tabletop RPGs. Unlike general-purpose 3D tools, BlastMini is the only platform that combines AI miniature generation with AI battle map generation in one tool. You describe any character, creature, or monster in plain English, and BlastMini generates a unique 3D model you can export as STL or 3MF.

BlastMini uses AI to turn text descriptions into 3D models. You type a description of your character (for example, "a tiefling warlock with curved horns and a tattered cloak"), and BlastMini's AI first generates detailed concept art showing front and back views, then converts that concept art into a full 3D model. The entire process takes just a few minutes with no 3D modeling skills required.

Yes. BlastMini offers a free tier that includes 10 custom miniature concepts and 3 AI-generated battle maps, no credit card required. Paid plans start at $14.99/month (Adventurer) for 100 concepts and digital downloads, $24.99/month (Dungeon Master) for 150 concepts with priority generation, and $199.99/year (Campaign Pass) for 600 concepts and 500 maps.

BlastMini generates concept art in about 30 seconds, and the full 3D model typically completes within 2–5 minutes. The exact time depends on model complexity and server load. Dungeon Master and Campaign Pass subscribers get priority generation queue access for faster results.

No. BlastMini is built for tabletop players who want a printable mini, not 3D artists. You describe your character or creature in plain English, review the AI-generated concept art, and download the finished 3D model. There is no sculpting, no rigging, no manual cleanup. You can drop the file straight into a slicer like Lychee, Chitubox, PrusaSlicer, or Bambu Studio and start printing.

Yes. BlastMini lets you regenerate the concept art with the same or modified prompt before committing to a 3D model. Iterate on the concept until you're happy with it, then approve it to generate the printable 3D version. This protects you from spending generation credits on a 3D model you don't want.

BlastMini can generate virtually any character, creature, or monster you can describe. Users create D&D player characters (fighters, wizards, rogues), monsters (dragons, beholders, mind flayers), NPCs, familiars, mounts, and even custom homebrew creatures. Because BlastMini uses AI generation rather than a parts library, you're not limited to pre-existing assets.

Yes. BlastMini is the only AI platform that generates both custom 3D miniatures and top-down battle maps in a single tool. You describe the environment you need (for example, "a ruined temple with lava pools and crumbling pillars"), and BlastMini generates a high-resolution, top-down 2D battle map suitable for virtual tabletops.

Yes. BlastMini generates high-resolution top-down battle maps that are fully compatible with Roll20, Foundry VTT, Owlbear Rodeo, and D&D Beyond. You simply download the generated map image and upload it directly into your virtual tabletop platform.

BlastMini supports a wide range of fantasy and tabletop art styles including heroic fantasy, dark fantasy, sci-fi, horror, steampunk, anime, and historical. Specify the style in your description, or pick from preset style options. The AI adapts the concept art and 3D model to match the chosen aesthetic — a tiefling warlock comes out very different in dark fantasy versus anime style.

BlastMini is built primarily for Dungeons & Dragons, where the design tools, base sizes, art styles, and workflow are all tuned to the D&D experience. That said, the output is technically compatible with any tabletop RPG or wargame using standard 28-32mm scale miniatures. Players of Pathfinder, Mörk Borg, Call of Cthulhu, and similar systems use BlastMini successfully. Wargame players (Warhammer, Age of Sigmar, Star Wars Legion) can also use it, though some game-specific bases or proportions may need adjustment in your slicer. Standard base sizes are supported (25mm, 28mm, 32mm, 50mm, 75mm, 100mm).

Yes. Because BlastMini generates models from descriptions instead of swapping pre-built parts, you can create creatures that no parts library has — a six-armed bone golem with raven wings, an aberrant fey-touched centaur, or whatever else fits your campaign. There is no limit to homebrew monster designs, NPC variants, or one-off campaign characters.

BlastMini exports 3D models in two formats: STL (universal 3D printing format for resin or FDM printers) and 3MF (modern compressed format recommended for PrusaSlicer, Bambu Studio, and Cura — smaller files with built-in error prevention). For 3D printing, we recommend 3MF if your slicer supports it, or STL for maximum compatibility. See our 3D Printing Guide for detailed settings.

Yes. BlastMini is a web-based application that works in any modern browser on desktop, tablet, or mobile. You can generate miniatures and battle maps from your phone, though the 3D viewer experience is best on larger screens.

Hero Forge is an asset-based customization tool where you select from pre-made parts (heads, armor, weapons) to build a miniature. BlastMini uses AI generation instead, meaning you can create completely original designs that aren't limited to a parts library. BlastMini also generates AI battle maps, which Hero Forge does not offer. Hero Forge offers physical printing services, while BlastMini provides downloadable STL and 3MF files for use with your own 3D printer or print-on-demand service.

General-purpose AI 3D generators target game developers, 3D artists, and product designers, with outputs that often need significant cleanup before they're usable. BlastMini is purpose-built for tabletop RPG players and Dungeon Masters. The platform combines AI 3D miniature generation with AI battle map generation in one tool, and the interface is designed around the D&D workflow: describe a character, generate concept art, then create a print-ready model at tabletop scale.

BlastMini uses a combination of advanced generative AI for both 2D concept art and 3D model creation. The system handles concept design, model generation, and tabletop-scale optimization automatically. Our AI stack is proprietary and continuously upgraded as better models become available — what matters for you is the output: print-ready 3D models from text, in minutes, with no 3D modeling skills required.

Yes, if you want a physical miniature. BlastMini exports STL and 3MF files that you can print on your own resin or FDM 3D printer, or send to a print service like Craftcloud or Shapeways. You can also view your models in 3D on your screen before deciding to print.

BlastMini files print on any consumer 3D printer. For best detail on character minis, resin printers are recommended: Anycubic Photon, Elegoo Mars and Saturn, Phrozen Sonic Mini, Prusa SL1S, and similar. FDM printers also work for terrain, larger pieces, and prototyping: Prusa MK4, Bambu Lab P1S and X1C, Creality K1, and similar with a 0.2mm nozzle. See the 3D Printing Guide for tested settings.

Both. Every BlastMini model is checked and optimized for tabletop-scale printing on consumer resin and FDM printers. Resin (MSLA/SLA) is recommended for character minis because it captures finer detail like fabric weave, faces, and weapon edges. FDM at 0.2mm nozzle works well for terrain, vehicles, and larger creatures. The printing guide lists tested resin types and slicer settings for each path.

BlastMini generates miniatures at standard tabletop scales matched to your selected base size. Medium creatures (25mm or 28mm round base) come out at 32-35mm tall, the heroic 28mm scale used in D&D and most wargames. Larger creatures scale up: 32mm base = 45mm tall (Large Hero), 50mm = 65mm (Large Monster), 75mm = 100mm (Huge), 100mm = 180mm (Gargantuan dragons and titans).

Yes, with one caveat: print success depends on your printer, slicer, and resin choice as much as the mesh. BlastMini models are pre-optimized for tabletop-scale resin and FDM. We recommend tough or ABS-like resin (rather than rigid resin) for character minis to avoid breakage on thin features like capes, hair, and weapon tips. Use the printing guide for tested slicer settings, support presets, and orientation tips. Print failure is most often a printer/resin/setting issue, not a mesh issue.

No. BlastMini delivers a clean unsupported 3D model so you have full control over support placement in your slicer. This is intentional: support strategies vary by printer (resin vs FDM), resin type, and orientation. Your slicer (Lychee, Chitubox, PrusaSlicer, Bambu Studio) will auto-place tree supports in seconds. The printing guide walks through recommended support settings for resin character minis.

Yes. BlastMini exports standard 3D file formats (STL, 3MF) that can be opened and edited in any 3D modeling software. Many users import their BlastMini models into Blender, ZBrush, or Meshmixer for further refinement, posing, or adding custom details before printing.

Commercial use rights depend on your subscription tier. The Adventurer plan includes a public/shared license. The Dungeon Master plan and Campaign Pass include private commercial rights, allowing you to use BlastMini-generated models in commercial projects, Etsy shops, or published content.
