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.

This project is completely open source, so the gate is wide open. Don’t have a 3D printer? Here’s a big set of PCB logic gates, but really, you can make logic gates out of almost anything.

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

Optical image (left) of a 3D-printed circuit comprising several geometries ... Velásquez-García told MIT News. The printed logic gates were reliable even after thousands of switching cycles.

Last week, MIT researchers published a blog post highlighting a paper detailing work on fully 3D printable electronics — namely a simple, semiconductor-free logic gate. The original paper was ...

Another plus of the featured circuit is the fact that it uses a 7486 IC for the XOR gate. Since this IC has 4 gates inside, the circuit can be expanded to build a four channel logic analyzer.
