ChatGPT told you to try A.
Then it told you to try B.
Then it apologized.
That's not a 3D printing tool. That's a language model doing its best with no real data behind it.
FixMyPrint doesn't generate advice. It looks up what actually worked - for your printer, your filament, your issue - from 58,000 real posts where the original poster came back and said “this fixed it.”
And when it generates settings, no AI is involved at all. The engine is rule-based, deterministic, and bounded by manufacturer specs. Same input, same output, every time.
Before it generates anything, it checks your hardware.
Eight compatibility checks run before a single setting is produced. Hard stops block genuinely dangerous combinations. Soft flags surface advisories you can acknowledge. The linter is always free - safety is never paywalled.
| Hard stop | Enclosure required ABS / ASA on an open-frame printer - blocks generation until resolved. | Blocked |
| Hard stop | Brass nozzle + abrasive Carbon fiber, glow, or abrasive filament on a brass nozzle - hardware conflict. | Blocked |
| Hard stop | Temperature ceiling Printer's max nozzle temperature can't reach what the filament needs. | Blocked |
| Advisory | Moisture risk Hygroscopic filament (PETG, Nylon, PCTG) with no drying step logged. | Flagged |
| Advisory | VOC / health risk ABS, ASA, or PC without enclosure ventilation. | Flagged |
Every state is computed from deterministic triggers - never a percentage, never a score, never a predicted failure date.
102 settings. 128 printers. 9 slicers. Zero AI.
The Settings Generator is 100% deterministic. No tokens, no sampling, no model temperature. Every value traces to a rule derived from manufacturer specs and filament data sheets. Same input, same output, every time.
Ranked by whether the original poster said it worked.
Not upvotes. Not how many times something was suggested. Whether the person who asked the question came back and confirmed the fix. That's the only signal that matters.
Built for makers who are done wasting filament on advice that doesn't know their printer.

Common questions
Does FixMyPrint use AI to generate my settings?+
No. Settings Generator values are rule-based, deterministic, and bounded by printer and filament specs. AI helps normalize issue wording and detect failures from photos. Fixes and settings come from the deterministic engine and community data.
What printers does FixMyPrint support?+
We support 128 FDM printer profiles including Bambu Lab, Prusa, Creality, Elegoo, Anycubic, Voron, Artillery, Qidi, Sovol, and more. If yours is not listed, select Other / Custom Build and add details in the notes.
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 are pre-flight checks?+
Before generating settings, FixMyPrint runs 8 hardware-aware safety checks on your setup. Hard stops prevent genuinely dangerous combinations while advisories flag risks you can choose to acknowledge.
What happens if my setup fails a pre-flight check?+
Depends on severity. Hard stops block generation with a clear explanation and suggested alternatives. Soft stops show a warning with a Proceed Anyway option for users who know their setup.
What slicers do you support?+
Cura, PrusaSlicer, OrcaSlicer, Bambu Studio, SuperSlicer, Simplify3D, Creality Print, Elegoo Slicer, and IdeaMaker. Settings are generated in your slicer's native parameter names so you can copy them directly.
What filaments are supported?+
PLA, PLA+, PETG, ABS, ASA, TPU, Nylon, Polycarbonate, Silk PLA, Carbon Fiber PLA, HIPS, PVA, and Wood Fill PLA. Each filament has its own temperature ranges, cooling profiles, and retraction values.
What does Photo Diagnosis actually do?+
Take a photo of your failed print and GPT-4o Vision identifies the most likely failure type. You get ranked fixes powered by the same community data 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 pricing work?+
Trial gives you 3 free Settings Generator uses per day and 3 Fix My Print diagnoses per day - no card needed. Pro is $9.99/month or $89.99/year and unlocks Photo Diagnosis, Maintenance Ledger, and higher daily limits.
