One can 3D print with conductive filament, and therefore plausibly create passive components like resistors. But what about active components, which typically require semiconductors? Researchers at…
They did do the thing that HewlettHackard is describing. Check out the AND gate in the linked article. The input paths are short and use small wires, but also cross the larger paths that normally link the output to ground. If both are active, the paths to ground are interrupted, and the resistor to VCC pulls up the output. So they did make logic gates. In the paper they also demonstrate NOT and OR.
I gather there’s a technical sense of “active” that’s used in electrical engineering that might not apply here, but to someone like me, with only a tinkerer’s knowledge of components, logic gates seem like enough to justify the term in the headline.
Well, a logic gate doesn’t fundamentally have to amplify… if the control current exceeds the output, it isn’t amplifying but fill performs logic. I am too lazy to look myself, but did they demonstrate amplification? If not, I think it’s doable.
