What io.github.codeofaxel/kiln does

Kiln lets AI agents design, queue, and execute physical manufacturing jobs on real 3D printers with zero human intervention. It exposes printer control through both a CLI and the Model Context Protocol (MCP), making any MCP-compatible agent (OpenClaw, Claude, GPT, custom) a first-class operator of your print farm.

Kiln is an open-source MCP server that lets AI agents (Claude Desktop, Claude Code, Codex, or any custom MCP client) drive real 3D printers end to end — OctoPrint, Moonraker/Klipper, Creality, Bambu Lab, Prusa Link, Elegoo, and Direct USB.

In a single conversation, an agent can design a part, slice it, queue it on the right printer, monitor the camera, recover from failures, and ship the result. No human in the middle.

pip install kiln3d

Then add Kiln to any MCP client. Open source for local printing.

Describe it or draw it. Kiln makes it real.

"a coaster with a photo of my dog Ash" — start to finish, from one sentence.

Paid tiers (kiln3d.com/pricing) add Git-for-3D versioning, product templates, assembly manuals, fleet workflows, SSO + SCIM, ERP webhooks, and long-term audit logs.

Why Kiln?

One control plane, any printer — OctoPrint, Moonraker, Creality, Bambu Lab, Prusa Link, Elegoo, Serial. Manage a mixed fleet from one place.
No printer? No problem — Outsource jobs to Craftcloud's 150+ manufacturing services through the hosted proxy, or use direct mode with your own provider credentials.
AI-native — 800 MCP capabilities and 221 CLI commands built for AI agents. Not a web UI with an API bolted on.
Describe it, print it — Natural-language to physical object pipeline: text or sketch → AI generation → validation → slice → print.
Decorate anything — QR codes, photos, logos, text, SVGs, and procedural textures (tiger stripe, marble, camo, wood grain, honeycomb) embossed or debossed onto any model with one command.
Manuals included — Multi-part prints can generate printable PDF assembly manuals with Bill of Materials, isometric step renders, mating arrows, and pause-and-check verification gates. (Pro)
Resume, don't restart — Cancelled or failed print? Resume from the exact layer it stopped on any supported FDM printer. No filament wasted. (Pro)
Modify mid-print — Add decorations, append features, or swap materials on a live print with atomic revert if anything goes wrong. (Pro)
Smart material routing — 25 materials, 45 brand-specific filament profiles (Bambu, Prusament, Polymaker, and more) across 11 material families. Intent-based recommendations with printer capability awareness.
Prints don't fail silently — Cross-printer learning, automatic failure recovery, closed-loop AI generation feedback (failed prints auto-improve future generations), preflight safety checks on every job.
Search → Slice → Print — Search and download 3D models from MyMiniFactory and Cults3D (search only), auto-slice with PrusaSlicer or OrcaSlicer, print — all from one agent conversation.
Safety at scale — 44 named per-printer safety profiles, G-code validation, heater watchdog, tamper-proof audit logs. Enterprise adds encrypted G-code at rest with key rotation, lockable profiles, RBAC, SSO, fleet site grouping, per-project cost tra
