MOST Delta filament as guide.JPG This page was part of an MTU course MY4777/MY5777/EE4777/EE5777: Open-source 3-D printing

Please leave comments using the discussion tab. The course runs in the Fall semester. It is not open edit.



The RepRap motto is "wealth without money" - for this assignment you are to create wealth by making an open source design that has value to you. It must be 3D printable on your MOST Delta and cost less than a commercial equivalent (if such a thing exists).

Assignment[edit]

  1. Design something of "high value" that you can 3D print on your MOST Delta
  2. Make sure someone else has not already done it - search http://www.yeggi.com/ and https://www.yobi3d.com
  3. Design 3D printable components with ONLY OS CAD packages (e.g. OpenSCAD, FreeCAD, or Blender)
  4. Upload your design under an OS license to http://youmagine.com/ - include: Source files, STLs, a picture, and a brief description including costs and $ savings. .
  5. Add picture, link to your YouMagine page with name, commercial equivalent link+cost, and economic savings to table below (see example).
  6. Print component and bring to class - Complete and due by 12/8

Grading[edit]

  • 30% Print quality
  • 20% Documentation
  • 50% Design (design for printing, aesthetics and function)

Automatic reductions: -50% no source or the use of non-OS software -10% per day for late
