From household objects like lamps and shower heads to printable pants and dresses, people can learn how to print those and more during free “Intro to 3-D Printing” classes at public libraries in Bonney Lake and Sumner.

Classes offered by the Pierce County Library System will cover what 3-D printing is, how it works and how free software tools can empower anyone to design and customize three-dimensional objects.

The class at the Sumner library begins at 10:30 a.m. on July 20. In Bonney Lake, the class will begin at 10 a.m. Aug. 19. Aside from an overview to 3-D printing, there will be time for hands-on learning, too.

Registration is required and can be done at http://www.piercecountylibrary.org/calendar/.

3-D printing has advanced significantly since it was first developed in 1983. 3-D printing is reshaping manufacturing and unlocking the potential for anyone to create.

It’s increasingly used in manufacturing and even the average consumer can buy a 3-D printer.
