For decades, scientists working in regenerative medicine have sought to be able to produce new organs readily. While it is still in its infancy, the application of 3D technology to generate organic tissue that may be transplanted is already producing results. Organovo and other laboratories and start-ups from all over the world have made generating liver tissue via 3D printing a major study area.

3D printing may also assist make the difference during critical phases of surgery. Doctors may create custom 3D printed models of anatomical representations to plan and rehearse for surgery prior to performing it.

3D printing's impact does not just extend to improving workflows and allowing for rapid prototyping. It may also make a direct difference in people's lives. There is optimism that 3D printing can provide new answers to the problem of high cost and tight specs, as there are 30 million persons worldwide who require artificial limbs and braces.

Dentistry is one of the most prominent users of 3D printing, and desktop 3D printers are becoming increasingly prevalent in dental labs and offices. In fact, thermoformed on 3D printed molds popular clear aligners are perhaps the most successful application of 3D printing to date.

The technology's flexibility and wide range of customization make it useful in a number of fields, including medicine. Customizing audio has been done for years by specialists and mold laboratories, using the technology to produce high quantities of bespoke ear goods such as hearing aids, protective plugs, and earphones.
