Engineers and scientists from the Lawrence Livermore National Laboratory and the University of California, Los Angeles are 3D printing mechanical logic gates ... an external binary signal from ...

A recent paper in Nature Communications discusses how to 3D print common logic gates using both macro-scale 3D printing techniques and a much smaller version with microstereolithography.

Transistors, which switch on and off to process binary data, are used to form logic gates which perform computation. "We saw ...
