Project Ignite was designed to make it easy for teachers to implement 3D Design and Printing into their classroom. It does so by putting a variety of step-by-step projects into one place. It also makes it easy to manage a virtual classroom. With it you can manage each student and track their progress. The accounts used by project ignite blend seamlessly into TinkerCAD which makes it very easy to get students started on a project.
Many of these projects are designed and used by other educators. If you have a great project you want to share, project ignite is a good place to do so as it can get your project into the hands of a large number of educators.
