3D printing is now universal across Windows devices including Desktop, Tablet, phone, and HoloLens. In this talk you will learn about the various app and game scenarios that are enabled by 3D printing. You will also see the various ways that developers can integrate 3D printing into universal windows and desktop applications in a consistent way across devices. You will learn about the 3MF format and consortium and the various ways for hardware and software companies can become part of the growing 3D printing, design, and manufacturing ecosystem. Finally, you will learn about how Microsoft is making investments in the future of 3D printing on Windows.
