DepthSight uses engineering research and design in areas such as optics, holography, electronics, robotics, mechanical design, and more along with a broad array of fabrication tools to turn ideas into prototypes.
A dash mounted cell phone holder provides a quick example of prototyping using a 3D printer.

This design was drawn in a CAD software package.

A 3D printer builds up the plastic model layer-by-layer.

The finished part fits a smart phone well.
