FDM PLA Basics

General-purpose settings for reliable FDM prints with PLA filament.

  1. Use a layer height of 0.15–0.20 mm for a good balance between speed and detail.
  2. Set infill to 10–15 % for display models; raise to 25–30 % for functional parts.
  3. Print at 200–215 °C nozzle temperature and 55–60 °C bed temperature for most PLA brands.
  4. Enable a brim when the base footprint is small or the model is tall and narrow.
  5. Use organic supports when overhangs exceed 55° and remove them gently after cooling.
