Revision as of 10:25, 28 July 2024

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)

  • Atomic Filaments black

Polyethylene terephthalate (PET)

Polyethylene terephthalate glycol (PETG)

  • Atomic Filaments black Carbon Fiber: result is very tough
  • Bambu Support-W (breakaway PLA support) $70 ($35/.5kg): works well enough, expensive
