Life is three-dimensional — and if start-up firms that dominated GigTank’s Demo Day have their way, the future of fashion, manufacturing and medicine will be, too.

The goal: woo more than 100 investors and venture capital firms that have an estimated $200 million to put into businesses they deem worthy. To be sure, the fledgling companies wanted barely a sliver of that.
