San Diego-based SolidProfessor has ten years in the technology education business, and the company recently announced it has added two new 3D printing courses. One course is "Introduction to 3D Printing" and provides an overview of 3D printing skills, a history of additive manufacturing, and working with CAD and 3D printing. The other course, "3D Printing with MakerBot," is geared toward those using MakerBot 3D printers. Both courses are free to SolidProfessor members, and if you are not a member yet, now may be the time if you are looking for high-quality 3D printing education resources.
