Few people enjoy going to the dentist, but if you can lie back and watch a big screen TV above you or listen to your favorite music, it’s not such a bad way to while away a few hours. Dentistry has certainly changed over the years, but 3D technology has brought about even more dramatic developments in recent years.

Some factory bosses have said that 3D printing will never replace mass manufacturing. Perhaps, but it does not have to transform production processes. Additive-manufacturing systems are being mashed together with traditional production methods, which themselves are improving with digital technologies. Even old-fashioned metal bashing and welding is going high-tech.
