Kiln in Claude

Use Kiln inside Claude

Add Kiln as a connector and design, check, and price 3D prints right in the conversation. No install, no 3D printer required — one sign-in and Kiln can make a model, confirm it will print, and tell you what it costs to have it made and shipped. Ordering is one more click, below.

Add it in three steps

  1. 1

    Add the connector

    Open this link and Claude opens its Add-connector dialog with Kiln filled in — confirm it. Or add it by hand: Customize → Connectors → Add custom connector, URL https://api.kiln3d.com/mcp.

  2. 2

    Sign in

    Claude opens a Kiln sign-in in your browser. Create a free account or sign in, approve access, and you are back in Claude — connected. Nothing to copy or paste.

  3. 3

    Ask

    Try “make me a coaster with my dog’s name on it”, “what material for an outdoor bracket that holds 5 kg?”, or “design a hole that fits an AAA battery”. Kiln does the rest and shows you a preview. Using Claude Duet? It picks Kiln up from your Claude account, so there is nothing more to add.

Using ChatGPT? Add Kiln there athttps://api.kiln3d.com/mcp-chatgpt. It designs, checks and prices the same way, and places the order too; a plan is bought or changed on kiln3d.com, signed in. The ChatGPT page walks through setup.

What you can do

Design

Describe an object and get a real, printable model — or start from a template (coasters, keychains, nameplates, trays, plaques, pet tags and more).

Decorate

Add text, a QR code, images or textures to a surface.

Check

Printability analysis, material recommendations, load and tolerance maths, and how to size a hole, joint, fastener, adhesive or magnet so parts really fit. Where nuts, magnets and inserts go in a part, and whether each goes in during a pause or after the print. Food-safety and skin-contact guidance included.

Document

Generate a dimensioned technical drawing or a step-by-step assembly manual.

Price

Get a real quote to have the part professionally printed — plastics, resin, nylon or metal — and shipped to you, and track an order you have placed. Placing the order lives on the full connector (below).

Where the rest of Kiln is

The connector carries part of Kiln. Ask it for something it does not carry and it says where that is: the free install on your own computer, or kiln3d.com.

Ordering: the full connector

The connector above prices parts and tracks orders, but never places one. When you want the part made, add Kiln’s full connector — same account, same sign-in, nothing to re-enter — and Claude can place the order for you. Craftcloud, a network of 150+ manufacturers, makes and ships it; you pay them directly at their checkout, and Kiln adds a small fee for arranging it (see pricing). The full connector can also look for an existing design on outside 3D-model sites before making one from scratch.

Prefer to add it by hand? Customize → Connectors → Add custom connector, URL https://api.kiln3d.com/mcp-full.

What about my own printer?

The hosted connector runs in the cloud, so it reaches your printer through Kiln on the computer next to it. Once the free install below is running there, ask about your printer and a live monitor opens in the chat, and your AI can send a design you made to the printer. You approve each print.

If you own a printer, the free command-line install adds printer control, slicing and live print monitoring on your own machine — the local half of Kiln, right where your printer is.

Accounts & pricing

Connecting creates a free Kiln account. Describing and designing your own parts is free. Ready-made products, textures, repairs and splits come with a small monthly allowance, and your first few manufacturing orders each month carry no Kiln fee. Paid tiers lift the limits and unlock deeper engineering data — see pricing.

Privacy, terms & support

Read our Privacy Policy and our Terms. Kiln is built by Hadron Labs Inc.; printing is carried out by third-party manufacturing partners, and your order contract is with the manufacturer. Questions or issues? Email adam@kiln3d.com.
