3D printing is a process for making a physical object from a three-dimensional digital model by laying down many successive thin layers of material. It brings a digital object into its physical form by adding layer by layer of materials. In this class, we will use the design program ‘Tinkercad’ to create digital models that we can then print using a 3D printer. Following a design process, students will imagine, plan, and create 3D models out of plastic filament.
