Polylactic Acid

Is a material that can be used in Fused Filament Fabrication

Notes

  • Biodegradable, derived from plant starch (corn, potato)
    • PHA is made from fermented sugar
  • Varieties with specific smell
  • Colors possible
    • Black colors have high level of carbon black filler, which can affect flow characteristics and change the melting point temperature

Usage

  • Temperature
    • Glass Transition: 60°C
    • Melting temperature: 160°C
      • Extrusion: 200°C
    • Small fan used to avoid remelting previous layers
  • Bed
    • Covered with Painter's tape
  • Strength
