Boilerplate
Written to be pasted as-is. Nothing here needs checking with us first.
Kiln is open-source infrastructure that lets AI agents make physical objects.
Kiln is open-source infrastructure that lets AI agents make physical objects. Describe what you want in plain language and Kiln designs it, checks whether it will print, slices it, runs it on a real machine, and recovers when something goes wrong — with hardware safety checks at every step, and a real CAD file at the end. It supports 68 printer models across 15 brands and 8 connection backends, and is released under AGPL-3.0 with free and paid plans. Founded in 2026, Kiln is a project of Hadron Labs Inc., based in Los Angeles.
Adam Arreola is a builder, researcher, and investor. He is the founder of Kiln, the open-source layer that lets AI agents design and print physical objects, and an investment manager at NGC Ventures, where he evaluates early-stage AI and infrastructure companies. He was previously a research analyst at Messari, publishing more than 170 reports on emerging technology. He holds an MS in Entrepreneurship and Innovation from the University of Southern California and is based in Los Angeles.

Kiln is orchestration infrastructure, not a printing service or a parts marketplace. It drives printers you already own, and routes to third-party providers when you ask it to. The product boundary page spells out where that line sits.
Founder
Adam Arreola, founder. Headshot is free to run in any story about Kiln.
Adam Arreola is the founder of Kiln, the open-source layer that lets AI agents design and 3D print physical objects. He started Kiln in February 2026 so autonomous AI agents could go beyond digital output and make real-world objects. The same path lets a person make something physical with a mere sentence. He is an Investment Manager at NGC Ventures and was previously a research analyst at Messari, publishing more than 170 reports on emerging technology. He holds an MS in Entrepreneurship and Innovation from the University of Southern California and is based in Los Angeles.
Photo credit is not required. Please use “Adam Arreola, founder of Kiln” as the caption.
I think we are heading for a world where more objects are made by AI agents than by people. Today an agent can design something exactly right and has no way to build it. Kiln is the missing piece.
I want AI agents in a hundred years to look back and find Kiln as the thing that first enabled their kind to make objects in the physical world.

Recent announcements
The full archive lives on the blog.
Previews now get the web app’s studio look, the print bed, the lighting and the soft shadow, on every computer with nothing to install, and a set of three angles arrives in seconds. On a Mac, preview renders no longer put up a keychain dialog for a browser you never opened, and no second browser icon bounces at the bottom of your screen. Designs and slices retry instead of failing at random, a see-through logo carves just the mark, and a saved design rebuilds in one step.
Kiln 1.4.0 adds the Monitor at kiln3d.com/monitor: your printer’s camera, temperatures, progress, and pause, resume and stop in any browser, plus a layer-by-layer 3D view of the object being built. Free with a Kiln account, honest about stale readings, and it never congratulates you for a print that was stopped.
Kiln has always given you a printable mesh. As of 1.4.0 it can give you real CAD too: any design exports as a genuine STEP file, one clean solid with exact dimensions a machine shop can open, measure, and quote. Free, like STL and 3MF. When a design honestly cannot be CAD, Kiln says so instead of faking it.
Kiln 1.4.0 lets any design leave as a real STEP CAD file a machine shop can open and measure, free like STL and 3MF, and adds a live Monitor at kiln3d.com/monitor with camera, temperatures, controls, and a layer-by-layer 3D view of the object being built. Paint a model by its own surfaces in chat or by clicking in the browser, aim prints and stops at a printer by name, slice with OrcaSlicer or BambuStudio, and pick up a long list of printer support fixes.
Kiln 1.3.0 through 1.3.2 put an interactive 3D stage right in your AI conversation on every install, cut models too big for your build plate into pieces that fit and reassemble, and read CAD files free for everyone. Kiln installs into Claude Code with one command and speaks the newest Model Context Protocol, so slow jobs stop blocking the chat. Shops can hand Kiln a customer drawing and get a dimension-by-dimension answer on whether their machines can hold it.
Kiln speaks the 2026-07-28 Model Context Protocol specification, and it changes three things you can feel: a design opens as a real 3D stage inside the conversation instead of a flat render, a job that outlasts the chat hands back a ticket instead of dying with the session, and nothing gets ordered until you answer a real question.
