The objects displayed on a shelf in the depths of UAV Solutions' headquarters in Jessup might look like toys, out of context.To the untrained eye, the plastic doodads – some thick, some thin, some glossy, others matte, and in a variety of subdued colors, like black, brown, tan and white – could be sandcastle molds, toy submarines – maybe DEVO hats in conservative hues.The reality is much more practical: They're parts of engines, circuit boards, radios. And each was printed by one of the company's 3D printers.Howard County officials toured UAV's facilities Friday morning as part of an event unveiling a new program to promote digital manufacturing in the region.In partnership with the Howard County Economic Development Authority, the county is working to bring 3D printers to small business owners and startup entrepreneurs throughout the state.County Executive Ken Ulman said the project's goal was to make a currently expensive technology accessible. The county budgeted $500,000 over two years for the initiative, which brings three 3D printers to HCEDA's business incubator at the Maryland Center for Entrepreneurship."How many small, startup companies are there out there that have an idea, have a prototype, but just can't afford the equipment?" Ulman said. "We know that the jobs of today and the jobs of the future are created by the private sector, but we also know that the public sector can do something to create the environment that enables private sector investment."
