The next step, obviously, is the creation of multi-material models ... sensors directly into 3D printed objects. These new sensors rely on a conductive filament custom-made for this study.

Conductive filament exists, but it takes more than that to 3D print something like a circuit board. The main issue is that traces made from conductive filament are basically resistors; they don ...

New research has identified a way to more properly send electrical signals through 3D printed material.
