Keeping notes on various FDM printing filaments here. Prices are per kilogram spool unless stated otherwise. Printing was done on a Bambu Carbon X1C unless stated otherwise.

Polylactic acid (PLA)

  • Bambu silky green 2024-06 $25: beautiful results

Thermoplastic polyurethane (TPU)

  • Overture 95A green 2024-06 $30: stringy as hell

Acrylonitrile butadiene styrene (ABS)

  • Bambu black/green 2024-06 $14 (4kg @ $56): solid workhorse

High impact polystyrene (HIPS)

Support material for ABS/PET, dissolvable

  • Bambu green Support-G $80 ($40/.5kg): expensive!

Acrylic styrene acrylonitrile (ASA)

  • Atomic Filaments black 2024-06 $19 (7kg @ $130): lay the first layer at 105, and remaining layers at 115.

Polycarbonate (PC)

  • Bambu clear black 2024-06 $40: befouled my .4mm hotend. Very lovely when it prints.
    • warping at 115, stick to builtin 110

Polyamide Nylon (PA)

Polycaprolactam (Nylon 6, PA6)

  • Atomic Filaments black

Polyethylene terephthalate (PET)

Polyethylene terephthalate glycol (PETG)

  • Atomic Filaments black Carbon Fiber: result is very tough
    • most reliable method seems to be cold plate (not textured PEI)
    • 270/60, no fans
  • Bambu Support-W (breakaway PLA support) $70 ($35/.5kg): works well enough, expensive

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: PA6-CF >> 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 > PETG/ABS/ASA > PLA
  • Filament density: PETG/PLA > ABS/ASA
  • Hotend temp required: PC > ABS/ASA > PETG > PLA
