Whytneigh R. Duffie; Kevin D. Barz; Tsvetanka S. Filipova; Katrina J. Donovan; Timothy M. Brenza; and Travis W. Walker, South Dakota School of Mines & Technology Several groups have studied the application of water-soluble resin formulations for 3D printing of materials4, with a common concern being the swelling of the polymer matrix during the dissolution process. In this … [Read more...] about Additive Manufacturing of Novel Surface-Eroding, Non-Swelling Anhydride Resins
Radiometry: Variations in Consistency Across 3D-Printer Models
By Paul Snowwhite, Katie Snowwhite and Hunter Peczynski, 7D Innovators, LLC Editor’s Introduction: The authors created an experiment to better understand why 3D printers created by various manufacturers perform differently even when using the same print settings or why a print fail occurs after multiple successful prints. Variables initially considered included material, cure … [Read more...] about Radiometry: Variations in Consistency Across 3D-Printer Models
