Kiln

MCP server for 3D printing. Connect any AI agent to any 3D printer — design, printability check, slice, print, monitor. Open source. Let's build. 🖨️

Kiln 1.3 is out: three releases this week, 1.3.0 to 1.3.2.

Most AI design demos end on a screen. Ask Kiln for a part and you can turn it over in 3D, then print it and hold it.

Kiln's own 3D stage: see it in your agentic chat, or get a url for your browser. 🧵

@observie Very aligned with what we’re building at Kiln: giving agents tools to go from geometry generation → manufacturing validation → directly operating the 3D printer.

Kiln is still early, but would love feedback if you get a chance to check it out

[Kiln @Kiln3d]

@LideSuddenly @MikeJamesBTC individually designed xyz on demand is what Kiln is built for!

from idea, to a 3d file, to a physical item in your hands, same day 😎 thanks for the shoutout!

[Kiln @Kiln3d]

@nikitabier Agreed; this era is going to be epic.

Kiln is doing its part to move the needle on bringing items into the real world, and can be used with any AI model to create 3D objects and then slice, print, and monitor the whole thing!

[Kiln @Kiln3d]

@muratcan Congrats on the new 3D printer!

We’re building Kiln to get an agent from an idea, to a file, to a sliced, checked, & monitored print. Works with over 70 printer models at this point!

Curious which part of the CAD → hardware loop you’re tackling first😁

[Kiln @Kiln3d]

@rileybrown This is the gateway, and we've been building Kiln to tackle it directly!

Once AI helps you design an object, the next question is: why can’t it handle the slicing and printing too? 👀

@DanKornas Let's build 🖨️

[Kiln @Kiln3d]

@boringdev77 @DanKornas Give it a try and let us know what you think!

Happy to help you get started and set up, just LMK. Also can and will quickly fix any issues you hit while using it, DMs are always open

[Kiln @Kiln3d]

@sainotsoai @DanKornas Appreciate it! You'll love the update we having coming too😁

@DanKornas gets it!

Kiln works with your AI model of choice, and runs Bambu Lab, Creality, Prusa, Elegoo, Klipper and OctoPrint printers, from prompt to printed part.

[Dan Kornas @DanKornas]

Getting from a prompt to a physical part still means too many tools.

Kiln is an open-source MCP server for builders who want AI agents to operate 3D printers.

It helps you move from a text prompt or sketch to a printed part by connecting MCP clients to design, validate, slice, and control print workflows.

Key features:

• MCP connection – works with Claude Desktop, Claude Code, Codex, Cursor, and other MCP-capable clients
• Design-to-print loop – supports text or sketch → AI generation → validation → slice → print
• Mixed printer support – covers Bambu Lab, PrusaLink, OctoPrint, Moonraker/Klipper, Creality, Elegoo, Duet, and direct USB
• Practical printer controls – includes discovery, status checks, uploads, slicing, print queues, camera snapshots, and print history
• Agent-readable output – CLI commands support `--json` for programmatic use

It’s open-source (AGPL-3.0 license).

@claudeai @LEJ_limited a tiny emoji becoming a real thing on your desk never gets old. Kiln does the whole trip in one chat, from idea to printer. check us out @Kiln3d !

[Kiln @Kiln3d]

@mattshumer_ Very cool🔥 we love using Claude with 3D printers. Seeing it clear the print bed in action is awesome to see

Kiln is open-source infrastructure that lets AI agents create real objects and control 3D printers. Design, decorate, slice, print, monitor, recover, all from one conversation.

Free & open source at the core (AGPL-3.0); paid tiers add more.

What's new in Kiln, 1.4.0 through 1.4.1.1. Your AI agent could already make you an STL. Now it can make you a STEP: real CAD a machine shop can open and measure. Thread. 🧵
