- 13. Materials That you should be using, but might not know about.
- 14. The Big Three ABS Lego Blocks Good Temperature Resistance PLA Compostable Cutlery Easy to Print PET Coke Bottles Best of Both Worlds
- 16. Flexible Materials Uses Types • Isolators / Dampening / Gaskets • Wheels / Treads • Drive Belts • SemiFlex – Usable in Bowden, Normal Printers • NinjaFlex (TPE) – Softer (60 Shore A), Requires supported tool path • TPU – Harder (85 Shore A), Requires supported tool path
- 17. New Materials HTPLA - Heat Annealed Matte Texture High temp, Strength Uses: Chassis, Impact Grippy, Strong Layers Uses: Grabbing Tools, Friction Wheel
- 18. Exotic Materials Carbon Fiber Metal / Wood / Ceramic Micro-fibers, not strand/cloth Very stiff, Great finish Uses: Chassis, Cable mgmt, Hubs Looks awesome, Weaker than PLA Uses: Aesthetic
- 19. Very Large Nozzle • 0.3-1.2mm layers • 1.2mm nozzle • Faster Prints • Stronger, Robust Output • Uses: Catchers, Shields, Fairings
- 20. Heat Set Threaded Inserts https://www.matterhackers.com/articles/fasteners-for-3d-printing
- 21. Rules of Thumb For Optimal Prints
- 22. YHT Rule 45 degree angles don’t need supports You might be able to bridge short distances You need supports for large overhangs
- 23. Print at Angle to Reduce Supports
- 24. Circular and Hexagonal vs. Rectangular holes Weak, Hard to Print Strong, Print w/o Support
- 25. Split & Orient Part for Zero-Support Prints
- 26. Print Orientation Rubric Tension = Parallel Strong Bending = Perpendicular Strong
