Specialized production manufacturing drives 3D printing in three industries, but prototyping will remain the key use case in more mainstream applications.

DETROIT — The 3D printing industry continues to grow by developing specialized applications for three industries: aerospace, medical and automotive. But widespread adoption across industries is still a long way off.
Several announcements made at the Rapid + TCT 3D printing industry trade show and conference reinforce the growth in innovation for 3D printing’s main industries. The announcements included the following:
- Smile Direct Club, a service that sends teeth alignment devices directly to consumers, will use HP Multi Jet Fusion 3D printing machines to produce individualized molds.
- Medical startup Marvel Medtech will use the XJet Carmel 1400 3D printer to produce ceramic cryotherapy probes that can identify, freeze and destroy breast cancer cells when they are first detected.
- The Renault Formula One racing team will use 3D-printed parts from Jabil Inc., one of the world’s largest contract manufacturers.
