"Printegrated Circuits” Bring the Smarts to 3D Printing
The article explores the innovative work of Oliver Child, a Ph.D. candidate at the University of Bristol, who has developed a method called "printegrated circuits" to embed microcontrollers into 3D-printed objects, making them smarter and more functional without requiring industrial tools. This approach bridges the gap between hobbyist-level Arduino projects and high-volume manufacturing by enabling low-cost, small-batch production of interactive devices. Child's technique involves using dual-extrusion 3D printers to inject conductive filament into embedded PCBs, overcoming challenges with material reliability and resistance. He emphasizes the importance of open-source sharing and envisions a future where functional, electronics-integrated designs can be printed and customized anywhere in the world.
