GIGTANK, a summer-long accelerator and funding program for aspiring 3D printing entrepreneurs set in Chattanooga, Tennessee, has selected their winning projects for this summer's event.

The GIGTANK program is an incubator for budding entrepreneurs in conjunction with The Company Lab (CO.LAB), and one element of the program is directed at Additive Manufacturing startups.

The selectees will be able to take advantage of access to a metro-wide fiber optic network with ultra-fast broadband, the opportunity to collaborate with conventional manufacturers to develop 3D printing pilot programs and access to conventional manufacturing facilities, experts and equipment.

The proposals which met the criteria will have access to an expansive range of 3D printing resources from leading technologists and experts at Oak Ridge National Laboratory's Manufacturing Demonstration Facility in Oak Ridge, TN. The program also includes $15,000 in initial seed funding (for a 5 percent stake in the company) and opportunities to attract additional investment capital from a large pool of investors.

The seven startups chosen can also take advantage of free housing for the duration of the summer program at the University of Tennessee at Chattanooga and collaborative workspace in the heart of the city.

The seven winners will also have the opportunity to participate in a cross-country investment tour of entrepreneurial funding bastions such as Silicon Valley and New York City. The program culminates in a nationally-promoted Demo Day, where participants present their progress to a strategic audience of investors, partners and media.
