3D Printer Evaluation Grant/Rubric


For this assignment, assume that you are in the 3D printer market for your school or business. A granting agency (me) has money for purchasing a 3D printer, but they want to make sure you have done your homework and know exactly what you need and want. Your task is to create a rubric that you will use to evaluate a number of printers (5-10). The list below highlights some of the things to think about when purchasing a 3D printer.


Factors to consider:

  • Cost
  • Kit or pre-built
  • Build Platform type/leveling/material used to adhere material to plate (tape? hairspray?)
  • Closed or Open Build Envelope
  • Cold or heated build plate
  • Internet Connectivity?
  • Operating System Requirements
  • Material used to print –Generic? Proprietary feed?  Color?
  • Cost of material used to print
  • Ease-of-use/Special tools needed?
  • Customer service plan/Cost for service/Turnaround
  • Manufacturer Issues
  • Build Envelope Dimensions
  • Print Resolution
  • Print Technology (Stereolithography, Extrusion, Phase Change Inkjet )

You will see charts comparing the printers. Consider using a similar chart to organize the printers you evaluate. Assign point vales for the different categories. The printer with the highest scores should be the one you select, unless you have a compelling reason to pick the 2nd or 3rd highest scoring printer.

Once you have evaluated the printers with your rubric, write up a short justification (275 words) in Word, explaining why you chose the printer you chose, what you will do with it, and how it will improve your classroom or business.
