What printers does FixMyPrint support?

We support 70+ popular FDM printers including all Bambu Lab, Prusa, Creality, Elegoo, Anycubic, Voron, Artillery, Qidi, Sovol, and more.

Does FixMyPrint use AI to generate settings?

Settings are generated by our deterministic rule engine - no AI, no randomness. Same input always gives the same output. Fix My Print and Photo Diagnosis use AI to identify problems, but the actual setting adjustments come from our engine with safety-clamped values.

How accurate are the generated settings?

We use conservative, reliable settings - always within safe ranges for your filament and printer. Every value is within validated hardware limits.

What slicers does FixMyPrint support?

Cura, PrusaSlicer, OrcaSlicer, Bambu Studio, SuperSlicer, and Simplify3D. Settings are generated in your slicer's native parameter names.

What filaments are supported?

PLA, PLA+, PETG, ABS, ASA, TPU, Nylon, Polycarbonate, Carbon Fiber PLA, and Silk PLA. Each filament has its own temperature ranges, cooling profiles, and retraction values.

What does Photo Diagnosis do?

Take a photo of your failed print and our AI analyzes it to identify the most likely issues. You get ranked causes with confidence scores, then one-tap fixes powered by our settings engine.

Do I keep my settings history?

Yes - every generation, fix, and diagnosis is saved to your history. You can revisit past results anytime from your dashboard.

Is a mobile app coming?
