Week 5 (14 to go!)

Reflection:

• SSTM
• Documention Pace
• Documentation Quality
• Nueval > Local Evaluation of Documentation

Week Recommendation:

Use this week to make meaningful progress on your Final Project

• Final Project Tracking Page > Final project development journal
• refine concept > what does it do? who are you making it for? what special features?
• produce (beautiful) system diagrams
  • Use your 2D CAD skills
  • what connects to what?
  • how many of what components are needed?
• make decisions about input/output devices, power supply

3D Scanning and Printing

Group assignment:

• Test the design rules for your 3D printer(s) > understand the capabilities of your 3D printer
  • Describe your 3D printer
    • make and model > Prusa XL
    • motion system type > coreXY
    • print volume
    • nozzle type and size: 0.4mm, 0.6mm, 0.2mm; brass, hardened nozzle (steel)
    • max nozzle and bed temp
    • control software
    • control electronics type
    • enclousure
  • print a characterization/test object that tests your 3D printer’s capabilities (and weaknesses)
    • overhangs
    • dimensional precision
    • clearance
    • fine detail
    • bridging
    • surface quality
    • artifacts
    • etc.

• Document your work and explain what are the limits of your printer(s) (in a group or individually) >
  • speed
  • size constraints
  • precision constraints
  • material constraints
• Document your work to the group work page on your lab site and reflect on your individual page what you learned

Individual assignment:

3D Printing

• Design and 3D print an object (small, few cm3, limited by printer time) that could not be easily made subtractively > understand clearly the meaning of Additive Manufacturing

  The Genius of 3D Printed Rockets

  3D Printing on the Moon and Beyond for NASA | Project Olympus - Off-world Construction

  • external and internal structures printed simultaneously
  • internal structures unreachable by end effector of subtractive machines
  • does not require assembly

  The Secret Behind 3D Printed Hinges

  3D Printing Procedure

  • model >> export STL
  • slice >> export Gcode
  • Print >> output object
