Assignment

group assignment:
test the design rules for your 3D printer(s)
individual assignment:
design and 3D print an object (small, few cm3, limited by printer time) that could not be made subtractively 3D scan an object (and optionally print it)

Previous year

• 2019 local session

Assesment

• 3D Scanning and Printing
• Learning outcomes
• Identify the advantages and limitations of 3D printing and scanning technology
• Apply design methods and production processes to show your understanding

Have you?

• Described what you learned by testing the 3D printers
• Shown how you designed and made your object and explained why it could not be made subtractively
• Scanned an object
• Outlined problems and how you fixed them
• Included your design files and ‘hero shot’ photos of the scan and the final object

  group assignment:
  use the test equipment in your lab to observe the operation of a microcontroller circuit board
  individual assignment:
  redraw an echo hello-world board,
  add (at least) a button and LED (with current-limiting resistor)
  check the design rules, make it, and test it
  extra credit: simulate its operation
