3D printers are great for schools and not just engineering departments of colleges and universities. There are entire curriculums available for K through 12 classes centering on Math, Science, History and yes Art. And departments other than Engineering can benefit from 3D Printers on the university level.
Chemistry and Physics departments can 3D Print molecules and atoms, making tangible what has been only described or viewed in a 2D image. History departments can 3D Print a village from the 17th century and give students a better understanding of the layout.
