Three minutes. Then ask your AI to make something.

  1. 1

    Install Kiln

    Pick your platform — each tab has copy-paste commands.

    Prerequisites

    Python 3.10 or newer. macOS 13+ ships with a compatible version, or install via Homebrew:

    brew install python@3.10

    Install Kiln

    The recommended install uses pipx for an isolated environment:

    brew install pipx && pipx ensurepath pipx install kiln3d

    Or use pip directly:

    pip install kiln3d

    Install from Source

    git clone https://github.com/codeofaxel/Kiln.git cd Kiln && pip install -e ./kiln

    One-Line Installer

    Clones the repo and installs via pipx automatically:

    git clone https://github.com/codeofaxel/Kiln.git ~/.kiln/src && ~/.kiln/src/install.sh

    Prerequisites

    Install Python 3.10+ and pip:

    # Debian / Ubuntu sudo apt install python3 python3-pip python3-venv
    # Fedora / RHEL sudo dnf install python3 python3-pip

    Install Kiln

    The recommended install uses pipx for an isolated environment:

    sudo apt install pipx && pipx ensurepath pipx install kiln3d

    Or use pip directly:

    pip install kiln3d

    Install from Source

    git clone https://github.com/codeofaxel/Kiln.git cd Kiln && pip install -e ./kiln

    One-Line Installer

    Clones the repo and installs via pipx automatically:

    git clone https://github.com/codeofaxel/Kiln.git ~/.kiln/src && ~/.kiln/src/install.sh

    Optional Dependencies

    # PrusaSlicer for STL slicing, OpenSCAD for text-to-3D sudo apt install prusa-slicer openscad

    Fastest: let your AI agent install it

    Already have Claude Code (or another agent with terminal access) on this PC? Paste this and it does the whole setup for you:

    # Paste this to your agent Set up Kiln (kiln3d.com) on my Windows PC. If Python 3.10+ isn't installed, install it with winget. Then run pip install kiln3d. Then run kiln install-mcp to connect Kiln to this agent. Then run kiln doctor and show me the result. Tell me if I need to restart anything.

    Manual setup: install Python

    Kiln needs Python 3.10 or newer. Open PowerShell and run:

    winget install Python.Python.3.12

    No winget? Install from python.org/downloads — and in the installer, tick “Add Python to PATH”. Avoid the Microsoft Store “python” shortcut; it causes PATH problems.

    Install Kiln

    Close PowerShell and open it again first, so it picks up the new Python. Then:

    pip install kiln3d

    Connect your AI agent

    Wire Kiln into Claude Desktop, Claude Code, or Codex:

    kiln install-mcp

    If it asks you to sign in first, run kiln signin. Restart your agent afterward, then confirm everything works with kiln doctor.

    You’re on the right tab

    This setup lets Kiln find your 3D printer on your home network by itself — nothing to look up or type in. The WSL 2 tab next to it is a niche option for advanced Linux setups; if you’re not sure you need it, you don’t.

    Prerequisites

    Inside your WSL 2 Ubuntu terminal, install Python 3.10+ and pip:

    sudo apt install python3 python3-pip python3-venv

    Install Kiln

    The recommended install uses pipx for an isolated environment:

    sudo apt install pipx && pipx ensurepath pipx install kiln3d

    Or use pip directly:

    pip install kiln3d

    Install from Source

    git clone https://github.com/codeofaxel/Kiln.git cd Kiln && pip install -e ./kiln
    WSL 2 Networking Note

    mDNS printer discovery (kiln discover) does not work in WSL 2 because of NAT networking. Use your printer's IP address directly instead (works for Ethernet and Wi-Fi LAN setups):

    # Connect directly by IP address kiln auth --name my-printer --host http://192.168.1.x:port --type octoprint --api-key YOUR_KEY

    Optional Dependencies

    # PrusaSlicer for STL slicing, OpenSCAD for text-to-3D sudo apt install prusa-slicer openscad
  2. 2

    Connect your AI

    Paste this into Claude Desktop, Claude Code, Codex, or any MCP-capable agent.

    {
  "mcpServers": {
    "kiln": {
      "command": "python3",
      "args": [
        "-m",
        "kiln",
        "serve"
      ]
    }
  }
}
  3. 3

    Ask

    Paste any sentence like this into your agent. Kiln does the rest.

    I have a Bambu A1, make me a coaster with my dog’s photo on it

You’re ready to print.

Free covers your first prints. Pro covers the rest of the workflow — version your designs, modify them mid-print, and leave the room while your agent handles the rest.
