I regularly test 3D printing filaments using the same methodology to make the results as comparable as possible. Over the years, I have collected the data from these tests into a spreadsheet, and in this video I analyze that database to compare different filament types and find out which ones perform best in each category.

The comparison includes PLA, PETG, PETG-CF/GF, ABS/ASA, ABS/ASA-CF/GF, PC, PC-CF/GF, PET-CF/GF, PA-CF/GF, PPA-CF/GF, and PPS-CF/GF materials.

The spreadsheet containing all of my filament test results is available to Patreon supporters and is continuously updated as new materials are tested.
