From idea to a print file — in minutes.
Describe what you need in plain language, and the AI builds a print-ready STL file: valid, watertight, and automatically verified. No 3D software, no prior knowledge.

Three steps to a ready file
No complicated software. Just describe — and receive.
Describe
Write what you need in plain language — attach a photo or sketch too. The AI asks only for what's missing to build the file.
Preview
Within seconds you get a rotating 3D preview from every angle. Not right? Change it in a few words until it's perfect.
Download
A verified STL, 3MF, or STEP file, ready to send straight to the printer — watertight, valid, print-ready.
Why it just works
We built all the hard parts — you just describe.
Automatically verified
Every file passes independent checks — watertight, consistent normals, real volume — before it reaches you.
No 3D skills needed
No CAD, no experience. If you can describe it in words — you can create it.
Fast
From idea to a ready file in minutes, not days. No waiting for a designer.
Every angle, before download
A rotating 3D preview. See exactly what you'll get — and change it before you print.
STL + 3MF + STEP
STL and 3MF for printing, STEP for CAD editing — every format you'll need, no conversions.
For shops and customers
Whether you own a printer or just want a file — the same simple, precise experience.
Frequently asked questions
Everything you need to know before your first file.
Do I need 3D or CAD knowledge?
Not at all. Describe what you need in plain words — the AI does all the technical 3D work for you.
What file formats do I get?
STL, 3MF, and STEP — STL and 3MF for printing directly, STEP for CAD editing or import into engineering tools. No conversions needed.
Is the file really printable?
Every file is validated as watertight, with consistent geometry and real volume, before you can download it — so it will load and slice. We still recommend a quick check in your slicer before printing.
What if the result isn't quite right?
Just tell the chat what to change. Describe the adjustment in words and get an updated file in seconds.
How long does it take?
Usually under a minute — from your description to a ready-to-print file.
Is formoapp.com the same as other companies named "Formo"?
No. Formo at formoapp.com is an AI 3D printing / STL generation tool, unrelated to any other product named Formo in a different industry, such as construction-industry hiring platforms or Web3/on-chain analytics tools.
