What it does
- Unified control plane for OctoPrint, Moonraker, Bambu Lab, Prusa Link, and Elegoo printers
- Integrated 3D model search across multiple marketplaces
- Automated slicing workflows using PrusaSlicer or OrcaSlicer
- Safety features including G-code validation, heater watchdog, and audit logs
- Support for external fulfillment via Craftcloud

→Search for a 3D model of a phone stand on MyMiniFactory and slice it for my Bambu Lab printer.
→Check the status of my current print job on the Moonraker printer and show me the camera feed.
→Queue a print for the latest sliced file on my OctoPrint printer.
→Find a 3D model of a replacement gear and send it to the fulfillment center for printing.
Original README from codeofaxel/Kiln
<em>Ask your agent to print something. It just does it — start to finish.</em> Watch the demo →
<details> <summary>CLI demo (terminal)</summary> </details>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.
Three ways to print
| Mode | What it is | You need |
|---|---|---|
| 🖨️ Your printer | Control OctoPrint, Moonraker, Bambu, or Prusa Link printers on your LAN — or remotely via Bambu Cloud | A 3D printer |
| 🏭 Fulfillment centers | Outsource to Craftcloud (150+ services — no API key required). Kiln handles quoting, ordering, and tracking. More providers as integrations launch | Nothing — no printer required |
| 🌐 External provider integrations | Route jobs through connected third-party provider/network adapters. Kiln does not operate a first-party network marketplace | Integrations as available |
All three modes use the same MCP tools and CLI commands. An agent can seamlessly fall back from a busy local printer to a fulfillment center or connected external provider integration — all in one workflow.
Why Kiln?
- One control plane, any printer — OctoPrint, Moonraker, Bambu Lab, Prusa Link. Manage a mixed fleet from one place.
- AI-native — 444 MCP tools built for AI agents. Not a web UI with an API bolted on.
- Prints don't fail silently — Cross-printer learning, automatic failure rerouting, preflight safety checks on every job.
- Search → Slice → Print — Search and download 3D models from Thingiverse, MyMiniFactory, and Cults3D (search only), auto-slice with PrusaSlicer or OrcaSlicer, print — all from one agent conversation.
- Safety at scale — 28 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 tracking, and PostgreSQL HA.
