What printers does FixMyPrint support?

FixMyPrint includes 128 printer profiles, 800+ supported via family fallback. If yours isn't listed, select Other / Custom Build and add details in the notes.

Does FixMyPrint use AI to generate settings?

Settings Generator uses no AI; Fix My Print and Photo Diagnosis use GPT-4o to identify problems. Setting adjustments come from the settings 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.

How does FixMyPrint pricing work?

Trial gives you 5 free Settings Generator uses and 5 Fix My Print diagnoses - no card needed. Fix Pass is $4.99 one-time for 3 uses of each plus one Photo Diagnosis - good if you're not ready to subscribe.

Built on verified data, not guesswork

FixMyPrint's engine draws from 10 authoritative sources- Cura, PrusaSlicer, OrcaSlicer, Bambu Studio, SpoolmanDB, Open Filament Database, Marlin firmware, Klipper configs, and real-world community outcomes. Every recommendation is bounded by manufacturer specs and adjusted by confirmed community success rates.

AI, scoped honestly

WHERE AI IS- AND ISN'T

Settings values are never AI-generated. Language and vision tasks are. Here's the precise split.

Deterministic Settings Engine

Where we don't use AI- Settings Generator

A deterministic rule-based engine covering 9 slicers, 13 filaments, and 102 settings. Same input, same output, every time. No tokens, no hallucination, no guessing.

Language & Vision Only

Where we do use AI- and why

GPT-4o classifies your natural-language problem description into a canonical issue type. GPT-4o Vision analyzes your photo to identify the failure mode visually. AI is used only where human language understanding genuinely outperforms rules- never for generating the actual settings values.

Community-powered

BUILT ON REAL FIXES THAT WORKED

Every recommendation is grounded in what the 3D printing community has actually confirmed - not theoretical advice from a textbook.
