Advances in processing, lower costs and improved performance could soon move 3D printing from prototyping to commercial production of aerospace and medical components.HANK HOGAN, CONTRIBUTING EDITOR, [email protected]For additive manufacturing, aka 3D printing, 2016 could be a very good year. Some big names are entering the field, advances promise better processing and signs point to movement into the mainstream. At the same time, the industry is working on developing standards while continuing to lower cost and improve performance — thereby addressing issues that have hindered adoption of additive manufacturing. Nine parts additively manufactured on a single sub plate, ready for final subtractive manufacturing via traditional milling, grinding and so on.
