In this paper an analytical dimensional performance evaluation and comparison is illustrated, done on benchmarks manufactured using two different 3D FDM printers: an industrial system, and an open-source one (a modified [email protected] Model 1 printer). Using a factorial analysis design of experiment (DOE), optimum process parameters were found to improve dimensional accuracy on rectangular test specimens, minimizing changes in length, width and height. [email protected] printer demonstrated to be a good platform, simple, flexible and inexpensive. Video CameraDownload : Download video (2MB) Video Camera
