While researching a topic, a student has taken the following notes:
  • Fused deposition modeling (FDM) is one type of 3D printing technology.
  • FDM is also called material extrusion.
  • FDM printers eject a modeling medium through a heated nozzle to build an object layer by layer.
  • Italian company Barilla uses FDM printers that extrude layers of semolina and water dough to create unique shapes of pasta.
  • Ukrainian entrepreneur Dinara Kasko uses an FDM printer that extrudes layers of silicone to create uniquely shaped molds for baking cakes.
The student wants to emphasize a difference between Barilla’s and Kasko’s uses of FDM printing technology. Which choice most effectively uses relevant information from the notes to accomplish this goal?
A
Barilla uses FDM printing to build layers of pasta dough into unique shapes, whereas Kasko uses FDM printing to build layers of uniquely shaped cakes.
B
While both Barilla and Kasko use FDM printers to create uniquely shaped 3D objects, Barilla is using the technology to produce food and Kasko isn’t.
C
Barilla and Kasko have developed different uses for FDM printing, a 3D printing technology also known as material extrusion.
D
FDM printing technology has many uses, from creating uniquely shaped pasta from semolina and water dough to constructing cake molds from silicone.
