Strengths Comparison

Polycarbonate Strengths

  • Very tough and stiff; doesn't shatter like PLA
  • High heat resistance (~150C softening region)

PLA Strengths

  • Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
  • Stiff non-composite thermoplastic, good tensile strength

Considerations

Polycarbonate Caveats

  • Often overkill and high effort for typical use

PLA Caveats

  • Creeps under sustained load
  • Poor heat resistance, UV degradation, can shatter on drops
  • Not great for sanding/gluing/painting/touch-ups

Frequently Asked Questions

Is Polycarbonate or PLA better for 3D printing?
PLA is generally rated higher (Tier A) compared to Polycarbonate (Tier B).
