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)

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

Assignment

3D プリント

  • additive process(付加工程) vs subtractive process(削除工程)
  • 3Dデータを作る（ダウンロード不可）
  • 小さいもの（数cm3）
  • subtractivelyで制作が困難なもの

FAQ: Define cannot be made subtractively
Answer: That cannot be fabricated with 3 axis limitations OR even if it’s possible to make it, it is complicated.

assignment

group assignment:
use the test equipment in your lab to observe the operation
of a microcontroller circuit board

individual assignment:
redraw the 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
extra credit: render it
