A research team has presented a 3D printer that overcomes a common obstacle: the separate manufacturing of components. This system is capable of producing complex and functional electronic devices in a single printing operation, integrating everything from the housing to the internal circuits. The advancement aims to simplify the production of wearables and sensors.
Multiple Nozzles for Integrated Manufacturing ??�/h2>
The key lies in a head system with multiple independent nozzles. Each one can process a different material simultaneously, alternating between structural polymers, conductive inks, insulators, or even flexible materials. This allows depositing layers that form, in the same process, the physical structure and the electronic traces of the device, resulting in an object ready for use without subsequent assembly.
Goodbye to assembly with pliers and infinite patience ??
This could mark the end of a glorious era: the one of joining tiny pieces that jump off the table, searching for the correct polarity of the LED you already soldered backwards, and discovering that the wire you passed with so much effort measures two millimeters less than necessary. Multimaterial printing promises a future where your wearable works right out of the print bed, not after three hours of frustration therapy and with fingers glued with cyanoacrylate.
