At RAPID + TCT in Pittsburgh, Roger Kelesoglu, director of sales enablement at Stratasys, previews the company's new Continuous-Build 3D Demonstrator. (It's not yet clear when it will be commercially available.) It allows for continuous production of plastic parts--with a cloud-enabled software management control system that enables automation on the front end all the way through the manufacturing process. Last year, the company's big announcement at the show was about size: the Infinite-Build 3D Demonstrator. The Continuous-Build 3D Demonstrator eases tooling and setup costs and lead times, allowing for lower-volume production of parts. This makes mass customization possible. TheContinuous-Build 3D Demonstrator also enables automation on the hardware side. He also discusses the ways the firm's Robotic Composite 3D Printer breaks some boundaries.
