Terms of use

Last updated 6 November 2026

These terms cover your use of PrintXO, the browser 3D modelling app at printxo.xslab.org, made by XS.Lab ("we"). Questions: hello@xslab.org.

Using PrintXO

You can use the free version for personal and commercial work. Don't try to break, overload or resell the service, or get around the Pro licence checks.

Your designs

Everything you model belongs to you. Your projects are stored in your own browser and in files you save; we don't receive or claim any rights to them.

PrintXO Pro

Pro is a subscription sold through Lemon Squeezy, which acts as merchant of record and handles payment, invoices and sales tax. Subscriptions renew automatically each month or year until you cancel from the link in your receipt email; Pro then stays active until the end of the paid period. A licence key may be activated on up to three browsers at a time.

Refunds

If Pro isn't working for you, email us within 14 days of a charge and we'll refund it.

Printing is your responsibility

PrintXO helps you design printable parts, but it can't know your printer, material or how a part will be loaded. Check designs before relying on them, especially anything that carries weight or affects safety. The software is provided as is, and to the extent the law allows we aren't liable for failed prints, damage or losses from using it.

Changes

We may update PrintXO and these terms. If a change affects paying subscribers we'll say so on this page before it takes effect.
