Concept Development

Concepts were developed using a morphological table:
Morphological Table for 3D print head

Pugh analysis was performed on several concepts: Pugh Chart

Additional concepts had Pugh analysis performed on them 11/04/14

Updated Pugh Chart

Updated Pugh Chart

From this chart we determined a hierarchy of designs, with the stock auger screw being at the top, followed by the gear pump and extrusion screws, and the gear and screw combination being at the bottom.


Rough concept sketches were developed from the Pugh chart and morphological table:
