Revision as of 12:30, 24 October 2019
Many 3-D printing companies have developed substantial resources to help teachers [23], [24] with large collections of free learning aid designs [25], [26]. 3D printers can be powerful tools for education as [1]:
- Open-source 3D printing provides a cost efficient means of STEM education.
- These technologies can also empower student-driven engaged learning.
Some benefits of 3D printing educational aids include:
- provides teachers with 3D visual aids that they can use in their classroom to illustrate challenging concepts
- 3D printers are cool so easier to get student interest as compared to 2D pictures
- Can enhance hands-on learning and learning by doing by having students make their own learning aids and all the concomitant skills associated with it (e.g. using OS CAD software)
As we know, distributed 3-D printing can often radically reduce costs and make real scientific equipment available even in schools.[2] This is particularly important for schools in developing regions.[3] In this assignment we will leverage basic science and design to help k-12 teachers make any subject easier to teach with learning aids at a low cost.
Assignment
- Identify an educational aid that you would like to design to be an open source 3D printable technology
- Make sure someone else has not already done it : Yeggi More than one of you can tackle the same technology in a different way. You may also improve upon existing designs if you do so in a significant way.
- Design 3D printable components with ONLY OS CAD packages (e.g. OpenSCAD, FreeCAD, or Blender)
- Publish a picture, stl and source code for your design on https://www.myminifactory.com/ and make sure to add it to the correct subject and grade level for https://www.myminifactory.com/category/education
- In the description on MyMiniFactory explain what your device is trying to teach, include theory, equations, links to Wikipedia etc. - whatever is relevant. Include the approximate cost of your print and then compare it to a commercial offering with their price and a hyperlink if available.
- Then add picture, link to your project page,cost savings if any, hyperlink to commercial equivalent in gallery below following the example.
- Print education aid and bring to class in bag with your name on/in it (online students drop off on due date by class time in box outside of my office) - See due dates on syllabus
Grading
- 20% Print quality
- 30% Documentation
- 25% Design (design for printing, plastic minimization)
- 25% Function - Does it work? (e.g. could it actually help teach someone something)
Automatic reductions: -50% no source or the use of non-OS software -10% per day for late
