Olga Kharif for Bloomberg Technology:  3D printing has long been a cool technology in search of a huge market. The industry may have found one in mass production.

Because of its high cost and slow pace, 3D printing’s use in manufacturing has been limited mostly to prototyping, making plastic molds for teeth alignment and creating tools. That may be about to change, potentially lifting the shares of printer makers 3D Systems Inc. and Stratasys Ltd. after a long slump. 

HP Inc. will introduce a $130,000 printer later this year, which it says can make parts at half the expense and at least 10 times faster than rival printers -- and likely use lower-cost materials. While HP’s entry could be a competitive blow, it may also help expand the market for 3D mass production, where other printer companies have already turned their focus.

Jabil Circuit Inc. plans to be an early adopter of HP’s device, printing end plastic parts for aerospace, auto and industrial applications that it currently makes using processes such as injection molding, John Dulchinos, vice president of digital manufacturing at the electronics-manufacturing service provider, said in an interview.  Cont'd...
