Keeping notes on various FDM printing filaments here.

The glass transition temperature is ideal for annealling.

I've got a Google Sheet now.

Qualitative comparisons

Manufacturers employ additives to change the properties of their filaments, which I don't attempt to address here. Properties may change across different batches of the same filament. These are very rough comparisons based off oral wisdom.

  • Impact strength: ASA > ABS > PC > PETG > PLA
  • Tensile strength: PA >> PC >> ASA > ABS/PETG > PLA
  • UV resistance: ASA > ABS
  • "Chemical" resistance: PETG > ABS
  • Melting temp: PC > ASA > PETG > ABS >> PLA
  • Heat resistance: PC > ASA > ABS > PETG > PLA
  • Printing speed:
  • Offensiveness (odor, VOCs while printing): ABS > ASA, PC
  • Acetone postprocessing: ASA/ABS only
  • Ease of sanding: PLA > PETG > ABS/ASA
  • Ease of painting: PLA > PETG > ABS/ASA
  • Tendency to warp: PC > ABS/ASA > PLA > PETG
  • Hygroscopicity: PA/TPU > PETG/ABS/ASA > PLA
  • Filament density: PETG/PLA > ABS/ASA
  • Hotend temp required: PC > ABS/ASA > PETG > PLA
