Tools needed for fabrication of the OSAT

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

Skills and Knowledge Necessary to Make the OSAT

  • basic measurement

Technical Specifications and Assembly Instructions

  1. Print the top part and down part separately.
  2. Joint them by heater through the edge of each part.
  3. printing time for each part is about 1.5 hours.
  4. Jointing time is about 15 min.

Common Problems and Solutions

  • Carefully when using the heater, don't burn yourself :)

Cost savings

  • If your solution is not a low cost one then it is not really appropriate.
  1. Estimate your costs: about 2 dollar.
  2. Find a commercial equivalent: about 10 dollar because of the material.
  3. 8$ savings and 80% savings
