Lesson Focus

Students will explore how 3D printers work. Then, working in pairs, they will use the same methods used by 3D printers to create a 3D model of an object.

Student Handouts

Age Levels:

8 – 14


Introduce students to:

  • 3D printers, additive manufacturing, and how 3D printing works
  • CAD and STL files used in 3D printing

Anticipated Learner Outcomes

As a result of this activity, students will be able to:

  • Take measurements of an object in order to build a model using a form of additive manufacturing similar to a 3D printer
  • Understand the process of additive manufacturing and the information required to 3D print an object
  • Work in pairs effectively
