Strengths Comparison

PLA Strengths

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

Silk PLA Strengths

  • Very shiny for show pieces
  • Supports can be easier to remove

Considerations

PLA Caveats

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

Silk PLA Caveats

  • Weaker than PLA
  • Can puff/popcorn and jam (especially with hot-air intake or multi-material single-nozzle)
  • Can 'trash' AMS/MMU
