New Commecial and 3-D Printing Shop Opens in Newark, DE

In a former newspaper office in Pomeroy Station in Newark, DE, the whir of an industrial 3-D printer is unmistakable.

"3-D printing is the next industrial revolution," said Joe Otto, who opened Sovereign Air, at 218 E. Main St., Suite 109, in early June. "I’ve always looked at it as the 21st-century machine shop."

With his new store—part workshop, part retail store and part learning laboratory—Otto hopes to introduce 3-D printing to Newarkers.
