FixMyPrint
3D Printing Troubleshooting Platform
FixMyPrint is a 3D printing troubleshooting and optimization platform built for makers, hobbyists, engineers, and professionals who want to spend less time debugging and more time printing. Available as a web application and companion mobile app, FixMyPrint pairs a powerful deterministic settings engine with a rules-based diagnosis layer - AI is used only to identify issues from uploaded photos - to deliver fast, accurate, actionable solutions.
It was built out of genuine frustration - every failed print sent me down a rabbit hole of Reddit threads, YouTube videos, and forum posts with inconsistent or outdated advice. FixMyPrint replaces that noise with a single, reliable tool.
The Problem
A successful 3D print depends on the perfect combination of dozens of variables: printer model, nozzle size, filament brand and material, slicer software, bed surface, print speed, cooling, and more. When something goes wrong, most users are left cross-referencing scattered Reddit threads, YouTube videos, and slicer forums - wasting filament, time, and patience.
The core pain is that 3D printing advice is highly contextual. What works for a Bambu Lab P1S running Bambu PLA on OrcaSlicer may be entirely wrong for a Creality Ender 3 running eSun PETG on Cura. Generic troubleshooting guides miss this nuance entirely.
The Deterministic Settings Engine
The heart of FixMyPrint is a rule-based settings engine - no AI, no machine learning - built from exhaustive research into slicer software, filament specifications, printer capabilities, and industry best practices.
- Slicers: Cura, PrusaSlicer, OrcaSlicer, Bambu Studio, SuperSlicer, Simplify3D
- Filaments: PLA, PETG, ABS, ASA, TPU, Nylon, PC, HIPS, PVA, and more
- Settings: 102 individual printer settings with safe parameter ranges
- Issues: 16 common issue types with ranked fix recommendations
The engine maps user inputs - printer, slicer, filament, and problem - to a precise, slicer-native settings output. Every setting uses the correct field name for the selected slicer, with values tuned to the specific filament and issue. The result is consistently more accurate than AI-generated advice, fully transparent in its reasoning, and free of hallucination.
AI Used Surgically
The Settings Generator and text-based diagnosis are 100% deterministic. AI enters the stack in exactly one place: photo recognition of failed prints - a task well-suited to GPT-4o Vision. Everything else is rules-driven.
Fix My Print - Non-AI Diagnosis
Select your symptoms from a structured checklist. A deterministic rules engine matches them against a curated knowledge base and returns a ranked list of fixes, each with a confidence score and severity rating, tailored to your printer, filament, and slicer profile - no AI involved.
Photo Diagnosis - AI Vision (Pro)
Upload a photo of a failed print. GPT-4o Vision is used solely to identify the issue type from the image - the resulting fixes are then generated by the same deterministic rules engine, for moments when you cannot articulate what went wrong, only show it.
