3D Metal Printer Senior Capstone @ UC Berkeley

Embed Size (px)

DESCRIPTION

Imagine a 3D printer which prints full strength aluminum with the simplicity of existing plastic printers. UC Berkeley Engineering seniors Rory Timar, Josh Stroud, and Andre Faroni tried to build a 3D metal printer for their senior capstone project in Spring '14.

2. Overview Design Process What + Why Overvie w Wrapup Q+A Goal: explore printing metal parts with welding Result: Lots of trial and error Heres what we learned 3. Why a 3D Metal Printer? Design Process What + Why Overvie w Wrapup Q+A ? 4. First Prototype Doesnt Work What + WhyOverview Wrapup Q+A Design Process Focus on learning about + prototyping TIG welding circuitry Tackle the riskiest part first! 5. Iterating on Power Circuit Car Ignition Coil Factory HV Caps DIY Transformer to Spec Flyback Transforme r DIY Capacitor Salvaged Transforme r High Voltage Arc Ignition What + WhyOverview Wrapup Q+A Design Process 6. Iterating on Power Circuit HF Current Control ` Continuous Current Power Supply HV Capacitor Zap Array Jewelry Micro-Tig Welding Insight! What + WhyOverview Wrapup Q+A Design Process 7. Beefier Microcontroller Powers Closed-Loop Control What + WhyOverview Wrapup Q+A Design Process Arduino Uno 16 MHz ARM Cortex M-4 168 MHz HF Current Control PI current control Capacitor Charging P voltage control 8. Misadventures in Startup Land Free Ventures What + WhyOverview Wrapup Q+A Design Process We want this! 9. Final Prototype Overview Wrapup Q+A Design Process What + Why 10. System Overview What + WhyOverview Wrapup Q+A Design Process 11. System Operation Overview Wrapup Q+A Design Process What + Why 1 2 3 12. System Operation Design Process Overview Wrapup Q+AWhat + Why 1 2 3 13. System Operation Design Process Overview Wrapup Q+AWhat + Why 2 31 14. Microcontroller Control Design Process Overview Wrapup Q+AWhat + Why 15. Experimental Data Design Process Overview Wrapup Q+AWhat + Why 16. Lessons Learned Know when to model, know when to build Invention = SMART trial and error. Design Process What + WhyOverview Q+AWrapup 17. Wrapup Goal: a 3D metal printer for the masses Insight: Combine TIG welding practice with existing 3D printer tech Final Result: an experimental platform to test + tune our welding process Design Process What + WhyOverview Wrapup Q+A Biggest Lesson: Even when the work you set for yourself wasnt finished, youve come too far to say its worth coming back 18. Timeline in Janurary Design Process What + WhyOverview Wrapup Q+A 19.
