What is usi3d?

usi3d is an independent 3D printing website: you create 3D models with AI from a text or a photo, get them ready to print and, if your printer fails, fix it with usi3d's AI. You use it in your browser, on your phone too, in Spanish and in English.

Create in 3D with AI

Describe the part, upload a photo or start from a guided project: the agent proposes the model and you check it before printing.

Your first generation is free; downloading the model requires the Pro plan.

Prepare your model

Paint it with real filaments, split it into parts with joints, close simple holes in the mesh, change the format and work out what it costs. All in the browser, without spending credits.

And coming soon, we print your design: we are not taking orders yet.

Fix your printer with AI

For any 3D printer, filament or resin: usi3d's AI tells you what to check and how to fix it, step by step and with its sources.

What it knows is also published as troubleshooting guides, with each manufacturer's official sources: you can read them without an account.

The shop

Filament, nozzles and spare parts, build plates and accessories for your printer, from trusted shops and with compatibility up front. You buy them on each shop's website.

Some links are affiliate links: if you buy, the shop may pay us a commission. It costs you nothing extra and the commission does not decide what we show.

A community of makers

Explore models published by makers and the usi3d Collection, with their licence in plain sight.

How you pay

With an account, the studio, credits and your diagnoses go together; the Free plan requires no card. Creating in 3D with AI and the troubleshooting AI use credits, and you see the cost before you confirm.

Free, Pro, Max and Business plans, with monthly credits and extra packs. If you recommend usi3d, the affiliate program gives you credits and commissions.
