Strengths Comparison

Silk PLA Strengths

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

TPU Strengths

  • Perfect layer adhesion; extremely impact resistant; nearly indestructible
  • Great for combat robots, tactical/rough-use parts
  • Rubber-like parts (gaskets, grips, bumpers, wheels)

Considerations

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

TPU Caveats

  • Slow printing; retraction can cause jams (especially in Bowden setups)
  • Stringing is common
  • Very moisture sensitive; wet TPU prints poorly

Frequently Asked Questions
