‘WHEN 3D PRINTING FEATURES IN THE MEDIA ONE WORD PREDOMINATES: REVOLUTION.
WHETHER THIS REVOLUTION IS OF THE INDUSTRIAL, TECHNOLOGICAL, OR CREATIVE KIND THE CONSENSUS SEEMS TO BE THAT 3D PRINTING MIGHT IRREVOCABLY CHANGE THE
WAY WE LIVE.”

MEASURING GOOD PROCESS Hype presented in the media doesn’t match the
state of the art.
Two 3D printing technologies are key to prototyping: FDM uses a heated nozzle and coils of resin SLA uses directed UV light and liquid resin
The industry is changing quickly.

MEASURING GOOD PROCESS
List two differences of FDM printing over SLA?
What are some of the characteristics of web technologies used in online CAD software such as TinkerCAD?
If 3d printers change the way things are manufactured, how will creators protect the intellectual property of their inventions?
