Spawn an object
into existence.
Kiln 3D is how AI agents make real things — safely, on any 3D printer.
Describe what you want. Kiln designs, prints, and monitors it — then branches, merges, and signs the version that works.
Bring your AI. We brought the rest.
Agents
Printers
Plugs into any agent. Operates any printer.
One thing today. Or a hundred this week.
Same printer. Same desk. One prompt each.
One thing, today
a coaster with a photo of my dog Ash
Bambu Lab A1 Mini
Or a hundred, this week
an ashtray with our startup’s logo

The full run
From idea to a printed product in an afternoon. Manual included. Pro
Multi-part prints ship with a printable PDF assembly manual — Bill of Materials, isometric step renders, pause-and-check verification gates.
A real PDF generated by Kiln from a simple 3-part desk hook kit — cover, mid-build, and final step from the same manual.
Git for 3D Printing Pro
Branch new ideas without losing the working version. Merge what prints best. Sign a release and prove later that nothing changed.
Works on three things you iterate on:
- Your designs — the mesh itself
- Your decorations — logos, textures, photo-emboss, brand assets
- Your features — reusable parts: a hat for an action figure, a mounting bracket, chamfers, fillets, pockets, holes
On Pro and up. Local-first — branches, merges, and signed releases live on your machine. Pro adds cross-machine cloud sync; Business adds team pull requests and approval gates; Enterprise adds audit log export, SSO, and step-up authentication on production releases.
What Kiln does
The five capabilities that make Kiln, Kiln.
Text & Sketch to 3D
Describe what you want or sketch it. Kiln generates printable models via Gemini Deep Think, Meshy, Tripo3D, Stability AI, or parametric OpenSCAD with a 14-component catalog (gears, threads, hinges, bearings). Design DNA preserves the source for iteration.
Git for 3D Printing
Branch new ideas without losing the working version. Merge what prints best. Sign a release and prove later that nothing changed. Works on your designs, your decorations, and your mechanical features. Runs offline on free tier; Pro+ syncs across machines via Kiln’s cloud.
Print → Monitor → Recover
Full lifecycle: slice, validate safety, upload, print, control speed with natural language, monitor with camera vision, detect failures, diagnose root cause, auto-fix slicer settings, and retry. One conversation, start to finish.
Safety at Every Step
44 named per-printer safety profiles with temperature and speed limits. G-code validation before every send. Preflight checks, emergency stop, heater watchdog, G-code interception. Agents can’t bypass safety.
797 MCP Capabilities, One Protocol
797 MCP capabilities and 220 CLI commands with --json output. Any MCP-compatible agent gets full access. Open source, AGPL-3.0 licensed, plugin-extensible.

How it works
From idea to physical object — then branch, merge, and print a better one.
Every step is an MCP tool. Agents compose the pipeline. Humans can run any step from the CLI. Every print outcome feeds the next iteration.
Before and after Kiln
One tool instead of a dozen. One conversation instead of a dozen tabs.
| Capability | Without Kiln | With Kiln |
|---|---|---|
| Create a 3D object | Learn Fusion 360, Tinkercad, or OnShape — or browse Thingiverse manually | Describe it or sketch it — Kiln generates, validates, and prepares it Patent Pending |
| Validate before printing | Slicer warnings + experience + wasted filament | 7-dimension scoring (0–100), auto-repair, mesh fix, auto-scale for AI models Patent Pending |
| Add decorations | Blender or Photoshop, then re-import and hope it prints | QR codes, photos, logos, text — emboss or deboss with one command Patent Pending |
| Add surface textures | UV mapping skills + texture software — not practical for most users | Tiger stripe, marble, snakeskin, wood grain, carbon fiber, honeycomb, etc. — applied directly to any model pro Patent Pending |
| Multicolor printing | Manually configure AMS slots in Bambu Studio or paint regions in PrusaSlicer | Automatic color segmentation, AMS slot mapping, and multi-gcode merging |
| Product templates | Design every coaster, keychain, and ornament from scratch | One command: "make me a coaster" — with QR codes, logos, and textures built in pro |
| Control your printer | OctoPrint, Bambu Studio, Creality Print, or Prusa Connect — one tool per brand | One interface for every supported backend — same commands, any printer |
| Monitor for failures | Bambu’s built-in camera or add-on webcam — no AI analysis, no auto-recovery | AI vision analysis across any printer with automatic failure recovery Patent Pending |
| Resume a cancelled print | Start over — the partial object is wasted | Resume from the exact layer it stopped, no filament wasted pro Patent Pending |
| Mid-print modifications | Cancel, redesign in CAD, re-slice, reprint from scratch | Decorate, add features, or swap material on a live print — with atomic revert pro Patent Pending |
| Manage a fleet | One dashboard per brand, no cross-brand routing or learning | Unified fleet with smart job routing, failure rerouting, and cross-printer learning pro Patent Pending |
| Learn from past prints | Start fresh every time — your experience stays in your head | Kiln learns what worked — same material + printer = better settings next time pro Patent Pending |
| Trust your printer’s calibration | Generic slicer defaults; your tuned values stay tribal knowledge, and every print’s calibration starts from zero | Reads your slicer profiles AND keeps learning from every print — per-printer offsets refine over time with full provenance pro |
| Safety beyond firmware | Firmware basics (thermal runaway, current limits) | Per-printer profiles + G-code validation + preflight checks + real-time interception |
| Outsource to pros | Visit Craftcloud or other services, compare quotes yourself | Route to 150+ 3rd-party services via Craftcloud directly from your workflow |
| Version-control your designs | Rename files v1, v2, v2-final, v2-final-FINAL — lose track of which printed right | Branch, merge, cherry-pick, A/B across designs / decorations / features — three-way semantic merge at the mesh level pro Patent Pending |
| Prove which version shipped | Email the STL and trust nobody edited it | Sign a version the way you’d sign a contract — anyone can verify later that nothing changed after you signed it pro Patent Pending |
| Sync designs across devices | Dropbox and hope nothing drifts | Push and pull between your machines through Kiln’s cloud — tenant-isolated, RLS-secured pro Patent Pending |
| Ship an assembly kit | Write a 30-page PDF in Word, photograph each step, hire a translator | Multi-part prints ship with a printable PDF — BOM, isometric step renders, multilingual sections, "what changed" diffs for revisions pro Patent Pending |
| Let AI run the whole thing | Not possible | Full pipeline via MCP — any AI agent, any printer, start to finish |
