Firmware, Hardware, & CFD Optimization of an FDM 3D Printer

Since 2016, Hiro has been improving the operation and expanding the capabilities of his FDM 3D printer. To date, a condensed list of modifications is as follows:

  • Custom firmware for improved temperature control and additional power outputs

  • GT2 belt upgrade & more rigid motion assemblies for reduced artificating

  • Custom extruder with dual Bondtech drive gears for precision extrusion

  • Endstop adjustment mechanism for faster tool-head-swapping

  • Nickel-plated copper nozzles for improved wear resistance and temperature stability

  • Upgraded cooling with CFD-optimized fan shrouds & centrifugal fans

  • Custom print head to maximize print volume & accommodate the above modifications
