Three steps to a ready file

No complicated software. Just describe — and receive.

01

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.

02

Preview

Within seconds you get a rotating 3D preview from every angle. Not right? Change it in a few words until it's perfect.

03

Download

A verified STL or 3MF 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

The formats every printer and slicer understands. Download and print — 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 and 3MF — the formats every 3D printer and slicer understands. Download and print, no conversions.

Is the file really printable?

Yes. Every file passes independent checks — watertight, consistent geometry, real volume — before it reaches you.

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.
