  • 10. End-Use Parts: Candidate Profile •Manufacturers needing plastic components for finished goods •Need low-volume production alternative • Pilot, bridge, production or end-of-life •Current methods limit what’s possible (considering time, cost) • Design optimization isn’t practical •Need efficiency, flexibility • With low-volume, high-complexity parts •Open to change • Or seeking innovation
  • 11. Camera Housing: EUP – Military Application Digital camera enclosure Low volume – Qty 3,000 PC/ABS High design iteration Complex geometry DDM chosen over injection molding Not moldable PC-ABS 8” x 1/4” x 1/2” 1 undercut per top & bottom
  • 12. Unmanned Systems Unmanned Vehicles • FDM viewed as key to “mass customization” • Easier adoption because of limited risks • Overnight production reduces cycle time • Direct build eliminates tooling needs Success Stories • Draganfly: Surveillance UAV • Leptron: Rapid Deployable Aerial Surveillance System (RDASS) • Embry-Riddle: Monocopter • Swiss UAV: Operational UAV Helicopter • Boeing UAV: AFRL Study Picture courtesy of NEO S- 300 VTOL UAV Swiss UAV GmbH Pictures courtesy of Draganfly Pictures courtesy of Leptron Pictures courtesy of Embry-Riddle

  • 14. Injection Molding: Application Overview Thermoplastic parts • Injected into tool/mold • High volume, Best repeatability • Most common method of plastic manufacturing Tooling • Mold cavity • Gates, runners, shut-offs • Cams, sliders, ejection system
  • 15. Injection Molding: Where Used High-volume plastic part production • Consumer products • Packaging. • Consumer electronics • Automotive • Aerospace • Electronics • Toys • Household goods • And many more
  • 16. Injection Molding: Candidate Profile Company type: • Custom molders • OEMs • Tool/die, model, services shops Industries: • Consumer electronics • Consumer products • Medical device That need: • Early, rapid product confirmation • Design, function, standards (e.g., UL, CE) • Early, rapid assessment of design for manufacturability
  • 17. Injection Molding: Process Overview Part design Tool design Tooling making Molding machine setup • Mount tool • Adjust injection settings •Sample (first article) run •Production run • Automated
  • 18. Injection Molding: Traditional Processes Tooling Manufacturing • Design • CNC setup • Milling • EDM •Considerations • High skilled labour intensive • Lead times – weeks to months • Costs – $1,000s to $100,000s
  • 19. Injection Molding: PolyJet’s Role Alternative to: • Machined soft tooling - Aluminium Process • Design tool or tooling insert • Print • Assemble tool • Fit inserts, add ejection system • Mount on press • Adjust injection parameters Advantages • Quick, cost effective and efficient
  • 20. PolyJet - Best Fit for Injection Molding When: •Thermoplastics with: • Reasonable molding temperatures • < 300 °C (570 °F) • Good flowability • Candidates: • PE, PP, PS, ABS, TPE, PA, POM, PC-ABS • Glass filled resins •Low quantities (5 to 100) •Mid-sized parts (< 165 cc [10 cu. in.]) • 50 - 80 ton press •Confirmation desired • Before cutting soft/hard tool
  • 21. PolyJet Benefits for Injection Molding: •Spec resins, production process • True functional evaluation •50% to 90% savings • Time & cost •Efficient • Automated with few steps •Early detection • Flaws in part & tool design • Thermoplastic’s performance
