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.

A series of mechanical logic gates are 3D printed using the Large Area Projection Microstereolithography (LAPµSL) method. In a Venusian rover, Pascall said scientists could build controls so if ...

Sure, we think of logic gates carrying electrons, but there are so many other mechanical means to do the same thing. ... Posted in News Tagged 3d printing, fluidics, pneumatic.

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 ...

Various logic gates—AND, OR, XOR, NAND, NOT, CNOT, and a half adder—could be put together using different combinations of robots. The DNA gates all take two inputs in the form of other molecules.
