3D printing is a complex additive process. Many things can go wrong, whether you're using a commercial or consumer-grade printer. This course reviews common 3D printer problems and highlights the settings that may help you get the best possible quality from your equipment, with a focus on printers that use filament. Learn how groups of settings interact with each other and reduce the trial and error often associated with learning how to "dial in" a 3D printer. Instructors Rich Cameron and Joan Horvath use the MatterControl slicing and control program as a baseline, but discuss other common programs that use these settings, including Cura and Slic3r.
