3DC is a free 3D printing design tool. They’ve worked hard to make their 3D CAD app available on multiple platforms including iOS and Android apps. This is great news for classrooms looking for solid iPads apps for use in STEM or STEAM curriculum. Chromebooks also have a web app available inside the web store. The free version is fully functional with the ability to export your models to .STL file format for 3D printing. Additional features are optional via the 3DC Pro version. Do you have a 3D Printer and want to start making your own designs from scratch? Be sure to watch my video and consider 3DC.
