Great to see people catching on to the vision. 👀
Kiln 1.5.0 is around the corner, and it’s our biggest release yet. Been working on it nonstop for months now. Stay tuned!
Bruh... this Claude Code MCP server is gonna make some new millionaires. 💀💸
It lets AI coding agents help you 3D-print real objects just by describing what you want.
~ Generate 3D designs from text prompts
~ Turn ideas into printable models
~ Slice models and send them to compatible 3D printers
~ Control and monitor printing through AI agents
Claude Code is literally becoming an all-in-one toolkit for developers and the AI gang to build, create, and automate whatever the f*ck they want. 😂

@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.
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).

1.3.1 and 1.3.2 are polish passes: much faster model repair, logos that print exactly as drawn (dashes stay dashed, corners stay sharp), and Kiln saying plainly when it could not fix something.
