FAQ
Last updated: 2026-05-26
Is it really free?
Yes, it's free. Not a trial, not a teaser, and there are no plans to change that any time soon. Paid features for power users may show up in the future (higher quotas, private mode, API access, commercial-use licensing), but there's no plan to put the core experience behind a paywall.
Do I need an account?
No. Anonymous use works completely. Sign up if you want higher quotas or to keep your models across devices.
Can I print copyrighted things?
No. Printytron will refuse anything that's a copyrighted character, branded IP, or a real person's likeness.
Where do my models live?
On secure cloud storage, attached to your session (or your account, if you're signed in). Models you mark public live in the gallery. Models you keep private stay private.
Can I delete a model from the gallery?
Right now, the workflow is to use the Report link on the gallery card and the developer will remove it. (Self-serve deletion is on the roadmap.)
What happens if the AI builds the wrong thing?
You refine it. That's the whole point of the chat. If after a few rounds it's still off, start a new model with a more specific prompt — sometimes resetting beats fighting context.
Can I print this in any material?
The STL doesn't care. PLA, PETG, ABS, ASA, resin — all fine, all the slicer's problem. Generated parts aren't validated for any specific material's mechanical properties, though, so use judgment for anything structural.
Is my chat private?
Yes. Other people can't see your build sessions. Only models you explicitly download and tick “show in gallery” become public — and even then the gallery only shows the name and description you chose, never your prompts or chat.
The model didn't load — what do I do?
Refresh the page. Your session and chat history come back. If it still won't load, start a new session. If it still won't load, email the developer.
Who runs Printytron?
An independent project. When you email, it goes to a real human who reads everything.
