Role

Curriculum Design & Instruction

Tools

Onshape, Laserprinter, 3D Printer, handtools, and a thumbdrive.

Duration

12 Weeks including introduction to Onshape and applicable mini-projects.

USB Redesign Project (WIP)

Some day I’ll loop back with more samples of documentation and student products. I’ve been doing this project in some capacity since 2012 even with the advent of USB type C!

Note: to add various levels including the injection moulded hot glue version. ALso, grab images from Onshape as web based programs are fleeting.

Unit Objectives

Essential Questions

  • EQ#1: How does additive and subtractive manufacturing work?
  • EQ#2: What is the advantage of using 3D printing in prototyping new products?
  • EQ#3: Why are skills in CAD modeling crucial in the design of 3D printed products?
  • EQ#4: How is CAD modeling useful in the scope of project development?

Enduring Understandings

  • EU#1: Objects can be modeled digitally
  • EU#2: CAD can be used to plan, develop and iterate on an idea before the physical production of an item or project
  • EU#3: Additive or subtractive manufacturing allows for physical prototyping of digitally designed CAD objects through CAM tools.

Meeting students at various levels or scaffolding

  • Step-By-Step walkthroughs and videos available for all Onshape CAD learning modules.
  • Students have access to guiding documents and videos for each Enclosure Design project iteration.
  • Students can model using different input methods or CAD software based on need.
