General Applications

  • Light-duty mechanical prototypes or housings
  • Snap-fit components, covers, or latches
  • Functional accessories under low stress
  • Joinery elements or slot covers
  • Fixtures or testing jigs

Advantages

  • Stronger & lighter compared to standard resins
  • Ideal for functional prototypes
  • Better impact resistance for light-use components

Disadvantages

  • Surface not as smooth as fine-detail resins
  • Still more brittle than FDM plastics like PLA/ABS
