Formo

What is Formo?

Formo is a chat-based AI tool that turns a plain-language description into a 3D print file. You say what you need, what it is for and the dimensions, and can attach a photo or sketch. The AI asks only for the details that are missing, then shows a 3D preview you can rotate. If it is not right, you describe the change in a few words and get an updated file.

Every file is checked before download for watertight geometry, consistent normals and real volume, and you get STL and 3MF for printing plus STEP for editing in CAD. Its guides are aimed at functional parts such as brackets, mounts, enclosures and replacements for broken parts. There is also a separate set of free parametric templates that need no account and no AI: knobs, L-brackets, shelf brackets, cable clips, screw-top containers, spur, bevel and herringbone gears, GT2 pulleys, sprockets, threaded rods, springs and boxes with lids, each with a few dimension sliders.

New accounts get 10 free credits, and each generation or edit of a file costs 1 credit. Paid plans are $5 a month for 75 credits or $10 a month for 200, and unused credits stay on your account. It suits makers who need a one-off functional part and would rather describe it than learn CAD.

What you can make

• Brackets and mounts
• Replacement parts
• Gears, pulleys and sprockets
• Boxes, containers and enclosures

How to use Formo

1. Open the create page and describe the part with its dimensions
2. Answer the AI's follow-up questions and check the rotating preview
3. Ask for changes in plain words until it fits
4. Sign up, generate and download the STL, 3MF or STEP file
