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



Assignment[edit]

  1. Identify an OSAT that you would like to design to be a 3D printable technology
  2. Make sure someone else has not already done it : existing designs here.
  3. Reserve your OSAT by signature tagging with ~~~~ next to the OSAT on the list generated by the Appropedia community: Requests for 3-D printable open source appropriate technology. You can add your own ideas to the list, more than one of you can tackle the same tech in a different way, you may improve upon existing designs if you do so in a significant way. Do this by 11/18
  4. Design 3D printable components with ONLY OS CAD packages (e.g. OpenSCAD, FreeCAD, or Blender)
  5. Create a Appropedia page for your project. (Easiest way to create a page is to search for the name of it and then click on the red link or in the list put double square brackets around it)
  6. Include the following sections on your page using the template below (copy and paste wiki markup into your page)
  7. Add picture and link to your project page in gallery below.
  8. Print component and bring to class - Complete and due by 12/4

Grading[edit]

  • 20% Print quality
  • 30% Documentation
  • 25% Design (design for printing, plastic minimization)
  • 25% Function - Is it OSAT? Does it work?

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

Gallery[edit]

Add your image and link the gallery below in a single line after the last one in the list

Title of the device or system[edit]

Project developed by [your name linked to your user account]
Status
This OSAT has been designed but not yet tested - use at own risk.
This OSAT has been prototyped.

You can help Appropedia by contributing to the next step in this OSAT's status.

Abstract[edit]

  1. Paragraph description of the OSAT - why is it Appropriate? What need does it fulfil? Are there case studies you have found of a technology being used successfully?
  2. Picture of completed print using
    Wood WorkingClamp Parts.png

Bill of Materials[edit]

  1. Provide a full BOM -- Materials needed for fabrication of device and alternative materials if they are not available, prices/sources of non-printable parts
    1. Upload and link to all source files
    2. Upload and link to all STLs

Tools needed for fabrication of the OSAT[edit]

  1. MOST Delta RepRap or similar RepRap 3-D printer

Skills and Knowledge Necessary to Make the OSAT[edit]

  • If you used special skill – link to relevant wikipedia or wikiversity articles/courses

Technical Specifications and Assembly Instructions[edit]

  1. Provide directions for print/assembly - be detailed enough in your “how to” to ensure that someone could construct the device from your description. Consider the elegance of IKEA like instructions.
  2. Include print time estimate
  3. Include assembly time estimate
  4. Including drawings or pictures of the device at stage of assembly at minimum. (http://www.appropedia.org/Special:Upload)
  5. Consider video if appropriate
Example video summary of textbook

Common Problems and Solutions[edit]

  • Include common mistakes/problems to avoid in building your OSAT and how to overcome them

Cost savings[edit]

  • If your solution is not a low cost one then it is not really appropriate.
  1. Estimate your costs
  2. Find a commercial equivalent
  3. Calculate $ savings and % savings

References[edit]

  • The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the <ref> </ref> and <references/> tags and can be in any format but should include all the information necessary for someone else to find the same information you did. For example: [1]
  1. web page: Department of Energy (DOE) Landscaping and Energy Efficiency, DOE/GO-10095 (1995) Available: http://www.eren.doe.gov/erec/factsheets/landscape.html

Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
