What FixMyPrint Does
Most 3D printing advice on the internet is a guessing game. A forum post tells you to lower your retraction. A reddit comment says your bed is too cold. A YouTube video swears it's the filament. Half the time the advice contradicts itself, and none of it is calibrated to your printer.
FixMyPrint takes a different approach. Instead of asking a model to invent settings on the fly, we built a deterministic rule engine on top of a database of real failures and real fixes. Tell the engine your printer, filament, slicer, and what's going wrong, and it returns concrete numbers - exact retraction distance, exact nozzle temperature, exact speed - already clamped to your hardware's mechanical limits and your filament's working range.
The result: the same diagnostic question always returns the same answer. No randomness, no drift, no “regenerate to see if you get something better.” Just settings that work.
There is one thing the engine deliberately does not do: diagnose hardware. The V2 pre-flight layer also checks known compatibility risks before generation: nozzle abrasion, PTFE safety, temperature ceiling, volumetric flow, moisture context, bed surface, enclosure fit, and extruder type. A loose belt, a worn extruder gear, a bent lead screw, or a failing hotend fan still requires physical inspection; no settings change will fix those. The boundary between what a slider can fix and what requires hardware attention is one of the most important - and most ignored - distinctions in 3D printing troubleshooting.
Eight Tools, One Engine
Fix My Print
Describe what went wrong - stringing, warping, layer separation, anything. The engine maps your symptoms to a ranked list of likely causes and returns the exact slicer changes that fix each one. No reading, no guessing, no retraction towers. Toggle Learn Mode to understand why each fix works - not just what to change.
Settings Generator
Pick your printer, filament, and slicer. Get a complete, ready-to-import profile with retraction, temperatures, speeds, flow, and acceleration already clamped to your hardware's limits and your filament's working range. Before settings are returned, the engine runs pre-flight checks for hardware compatibility, PTFE safety, nozzle abrasion, volumetric flow, bed surface, moisture risk, and environment advisories.
Pre-Flight Checks
FixMyPrint catches setup problems before you print: abrasive filament through brass, PTFE-lined hotends above safe temperatures, volumetric flow violations, moisture risk, bed surface mismatch, extruder limits, enclosure compatibility, and VOC advisories. Hard stops block genuine hardware risks; advanced users get clear override paths where appropriate.
Photo Diagnosis
Upload a photo of a failed print. The model identifies the failure mode visually, then hands off to the same rule engine to produce concrete settings adjustments. Useful when you can't quite name the symptom.
Print Journey
Track every print, every fix attempt, and every result. Build a personal history of what works for your specific printer and filament combos so you stop solving the same problem twice.
Slicer Export
Generate settings once, import everywhere. FixMyPrint exports native profile files in your slicer's exact format - .cfg for Cura, .ini for PrusaSlicer, .json for OrcaSlicer and Bambu Studio, .fff for Simplify3D. No manual copy-pasting of values into your slicer.
Filament Database
1,317 brand-specific filament profiles aggregated from 10 sources - Cura, PrusaSlicer, OrcaSlicer, Bambu Studio, SpoolmanDB, the Open Filament Database, and more. Exact recommended temps, drying guides, moisture signs, and storage requirements per brand. Because “Bambu PLA Basic” and “generic PLA” are not the same filament.
Free Guides
43 long-form troubleshooting guides and step-by-step how-tos - one per failure type, one per calibration procedure. Built from the same community fix data that powers the engine. No signup required.
The Data Behind It
FixMyPrint isn't a wrapper around a chatbot. It's a rule engine built on a structured database of community fixes - real settings that solved real failures across thousands of printer/filament combinations. Every recommendation traces back to documented, reproducible results.
Who It's For
New printers who don't want to spend their first month learning the difference between linear advance and pressure advance just to print a benchy without stringing.
Hobbyists switching filaments who already know their printer but need a clean baseline for that new spool of PETG, TPU, or PC blend - without burning a weekend on calibration cubes.
Makers switching to a new filament brand who want brand-specific temps and drying requirements - not generic PLA advice that may not apply to their specific spool.
Print farms and small businesses who can't afford the time to debug each failure mode by hand and need consistent, reproducible settings across multiple machines.
Anyone tired of forum threads that end with “works on my machine” and want a starting point that's actually grounded in data.
Makers who've been burned by bad advice who changed four settings and two screws at the same time, made the problem worse, and want a structured elimination approach that changes one variable at a time and explains why.
