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:
- 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 )
Sites with printer information:
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.
|Write up Rubric (One point for name on paper)|
|Item / Value||0||2||3|
|Write Up||Fewer than 275 words||275+ words|
|Report lacks information about learning/business need||Report includes reference to learning/business need, but lacks connection from hardware decision to need||Report includes information
about the learning/business
need and ties the hardware
decision to the need
|Rubric Results||No discussion or chart is included in report||Chart of rubric results is included but not discussed in write up||Rubric results are shown
in chart and are discussed
in write up
|Item / Value||0||10||20|
|Rubric||Rubric lacks comparative factors related to the decision||Rubric analyzes hardware on the basis of three or fewer factors, or factors are unrelated to the decision||Rubric analyzes hardware
using a variety of factors
(five or more factors-
there are 15 in the list)
related to the decision
|# of printers evaluated||One printer evaluated||2-4 printers evaluated||5-10 printers evaluated|
