Kiln

Overview

Kiln provides AI agents with end-to-end control of various 3D printers including OctoPrint, Moonraker/Klipper, Creality, Bambu Lab, Prusa Link, and others. It enables a natural-language-to-physical-object pipeline where agents can design parts, slice them, queue prints, monitor progress, and handle failures. The solution offers both free and paid tiers with additional features like Git-for-3D versioning, failure recovery, and smart material routing.
