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.

That means perfectly custom fit shoes, and surgery based on a lifelike replica of your insides, both thanks to 3-D technology.

Eleven new companies showed their mettle and their major plans on Tuesday at Girls Preparatory School, during the culmination of Co.Lab's summer-long accelerator program. 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.

"We're all eating Ramen noodles," joked Clay Posey, executive vice president of 3D Ops, one of GigTank's seven start-ups focusing on 3-D printing.

As its name suggests, 3D Ops has developed technology to help surgeons operate. The company takes CT scans and MRIs, for example, and builds anatomical 3-D models -- of a heart valve or brain, for example -- so that surgeons can better plan medical procedures. The way things work now, surgeons mentally construct images into three dimensions and proceed from there, said Daniel Hampton, the company's president and CEO.

"That can lead to misunderstanding, complications," Hampton said.

It also takes longer, and "time can mean life," he said.

Hampton recently relocated from Memphis to Chattanooga in order to base the company here. Gig City's super-speed Internet is key to the company's success. That's because its business model needs fast uploads for the models it creates.

3D Ops was looking for $2 million, the most of any company presenting Tuesday.

The company is in a "very serious conversation" with one local hospital, which Posey declined to name. That hospital is keen on getting a pilot program in place. And University of Miami Hospital should be in town in August to talk with the team, he said.

At least 500 people were at Tuesday's event, which also featured healthcare technology start-ups and one smart grid company. The day-long annual event was Co.Lab's third.

The 11 teams that presented Tuesday had received $15,000 each in seed money, free housing at University of Tennessee at Chattanooga and free work space, as well as mentoring. About 65 companies wanted to be part of the program, which started in May.

Last year, seven start-up ventures pitched their business plans. That event raised about $800,000 from investors, said Mike Bradshaw, president of Co.Lab and GigTank.
