3D printing and modeling enables learners to make solid models of ideas and objects that are not practical by any other means. Students will showcase projects and learning that are not possible or unrealistically difficult to produce other than with 3D modeling and printing. Students will demonstrate how to design and print three project examples that demonstrate the learning and creative potential of 3D printing. 1) exercise in iteration: a capacitor powered vehicle 2) printing gears and making clocks 3) designing with math: making (real) wind turbine blades
