I just launched something I wish existed 3 years ago.Introducing GCodex — a 100% free, fast G-Code Viewer & Machine Simulator built for both 3D Printing & Bioprinting.Open any .gcode, .nc, or .g file and instantly get:
✅ Full 3D & 2D Toolpath Visualization✅ Layer-by-Layer Inspection — slide through every detail✅ Real-time Print Analysis — extrusion, travel, retract & estimated time✅ Built-in G-Code Editor with find & replace✅ Multi-format Export: STL, OBJ, SVG, CSV, JSON✅ Universal Support: works with CNC, FDM & Bioprinters✅ Firmware Ready: supports Marlin, Klipper & more
But the real reason GCodex exists is because of bioprinting.Most bioprinter workflows today depend on modified FDM slicers and closed-source software that were never designed for bioscaffold analysis, hydrogel construct validation, or custom DIY bioprinter systems. There was no lightweight tool available to properly inspect scaffold layers, analyze construct paths, and validate biofabrication movement before printing.So we built GCodex to solve that problem.🔒 Zero uploads. Zero signups. Zero cost. Forever. Your file never leaves your device — that’s not just a feature, that’s a principle.Whether you’re a hobbyist running a Bambu Lab, a machinist verifying CNC paths, or an engineer validating tissue engineering scaffolds — GCodex was built for you.The tool is live right now.
