How does 3D printing work? This invention educator explains

SUMMARY

Doug Scott teaches engineering and robotics at Hopkinton High School in Hopkinton, Mass. In an interview this week at the U.S. Patent and Trademark Office's (USPTO) National Teachers Summer Institute (NSTI), Scott explains the basics of how a 3D printer works, what it can make — and how students can create their own designs.

When he is not in the classroom or in his basement 3D printing, Scott mentors teachers from all over the country on how they can help their students become inventors, including at NSTI and PBS NewsHour Classroom's Invention Education program.

Scott is clear about one thing: Anyone can be an inventor.

In fact, on Dec. 6, 2016, the U.S. Patent and Trademark Office issued Scott alongside 23 of his students Patent 9,511,833 B2 for inventing a robot for underwater search and rescue operations, and particularly suited for searches under ice.
