GitHub contribution heatmaps as filament test & calibration prints. Grey & black filament is stock PLA Prusament. Orange/green/red prints is ye olde M3D PLA 3D Ink. White print in the back is GreenGate3D recycled PET-G.

Note the newer Prusament doesn't have nearly the stringing as it seems - just more apparent on black. The M3D filament was old & the worst at stringing. The PET-G struggled a bit at building towers, showing I need to tweak my PET-G settings.

Trying out a spool of GreenGate3D's recycled PET-G - pretty happy so far. Should have listened to Prusa3d's defaults and used a warmer bed, definitely needed a z-axis tweak.

Very happy with GreenGate3D itself - very nice handwritten note for my first order (and Starburst). I would love to see a cardboard spool and paper used for packaging instead of foam sheets, but overall happy to see a U.S. company manufacturing filament from recycled plastics!
