One of the best 3D printing course I enrolled for, the specialization covers all the aspects of the field and has great project and assignments which lets us practice from the point of view of Legal, Manufacturer, Consultant as well as the creative hobbyist. Thank you UIUC for creating this course.

decent course u should show u r interest and self learning which they detailly provided

The peer-assignments for the courses are taking way too much time to get graded and this is very frustrating for the learners. Secondly, I didn't get my specialization badge even though I successfully completed all the 5 courses in the 3D printing specialization.

A crucial suggestion: Please include a direct interaction with the course instructor in discussion forums so that learners can clear many doubts which require the assistance of the instructor.
