DAYTON-When Corey Suffield graduated from Dayton High School in 1998 he was looking for a career in video production.

Twenty years later, Suffield operates a successful computer repair business in an office inside Suffield's Furniture, his parents' furniture and appliance store on Dayton's Main Street.

While that is not surprising, considering that Suffield has been fascinated with "electronics, computers and motor control stuff" for as long as he can remember, it is pretty remarkable that he is making items for use in his office on a 3D printer that he built himself.

None of that is surprisin...
