Team Vision for System-Level Design Phase

For the systems design phase, our team planned to finish our benchmarking for printer selection, research and benchmark sensors and microcontrollers, decide on a print material, create an initial budget, and finalize our printer, sensor and microcontroller choices. This was an overeager goal for the team, but did pave the way for a very detailed research plan. During the systems design phase, our team completed the following:

Printer Selection Criteria

  1. The printer is within our printer budget of about $2500.
  2. The printer has a large community to help with any issues that may arise.
  3. The printer is relatively easy to use.
  4. The printer is open source with its hardware and software.
  5. The benchmarking shows printer is reliable.
  6. The printer has a good print resolution to print high quality parts.
  7. Purchasing the printer is easy and will be delivered in no more than 7 business days.
  8. The printer is safe if used intelligently.
