Today:

Upcoming Stuff/Due Dates:

  • see classroom
Class 27: Friday, 11/18/22

Propose solutions to these Global Problems: 
1.  Connecting objects with fishing line is difficult and takes too long.
2.  Hanging things from the classroom ceiling is difficult and takes too long.
Consider this:
3.  Why do people resign themselves to using difficult, time-consuming methods and/or technology?

Today:

  • Hang your mobile from the classroom ceiling. 
  • I am predicting a lot of late submissions, so...  The top contest finishers will be selected from the mobiles that are turned in today.  Second tier (late) mobiles will still be judged, and they will receive the same feedback as the on-time mobiles, but they will be ranked after those handed in today.  Turning your mobile in late will not affect your ultimate project grade (at least not in the long term; you may have a zero for a while)

Upcoming Stuff/Due Dates:

  • Enjoy your break!  (and, maybe, finish your mobile, if you didn't finish today)

What are some design considerations for 3-D printing?  What should you avoid?  Why?
--Undercuts and support, adhesion to bed, minimum thicknesses, infill, scale (mm), and file type (.stl)

Today:

  • Reminder -- we will be working on several projects at once.  3-D printing takes time, and there is no sense in doing nothing while you wait for your printed part.  We are going to move on to design for laser cutting before we finish the stomp rockets.
  • If anyone is ready to print, submit your file for printing. 
    • 1 -- confirm that everything is the size that you want, and that you're measuring in the units that you want.
    • 2 -- set your scale to millimeters
      • Tools (yellow gear or tab)
        • Options
          • Units
            • Millimeters
    • 3 -- save your file as a .stl file (stereolithography).  Include your name in the name and make it a helpful name.
    • Submit your file in Google Classroom -- see "Submit your Stomp Rocket .STL file for 3-D Printing"
  • If you have designed and submitted a rocket file for 3-D printing, begin the "Design for laser cutting" assignments in Google Classroom.
