Freeform Concrete 3D Printer Unveiled, 3Drs

[T]his new construction 3D printer is immensely flexible in use. Thanks to its replaceable printhead (based on Desamanera’s D-Shape method), it enables users to 3D print numerous building materials, including stone and concrete. Its designers see no reason why steel or isolation materials shouldn’t be added to that list in the future either. And thanks to a partnership with Eindhoven-based AcoTech, the developers are looking into mounting the 3D BUILDER onto tank threads to enable it to autonomously find its way around construction sites.

Transit Nerds Get a Handy New Tool for Easily Turning Data Into Apps, WIRED

[C]reating useful transit apps and websites is hard. Developers must gather data from every agency in the area, which is a bear when you consider 30 transit agencies serve the San Francisco Bay Area alone. They have to format it, and ensure it’s properly licensed. This is before the design and coding needed to actually build the app. To ease this pain, Transitland collects and standardizes public data sets for developers. After launching a year ago with data from New York and San Francisco, the service, offered by mapping platform Mapzen, expanded to more than 200 regions this week.
