Oak Ridge National Laboratory has bridged the scale-control divide with a new modular extrusion system that multiplexes multiple smaller extruders into a single high-output stream. By merging molten polymer within a patent-pending aluminum bronze Y-nozzle, the system achieves large-scale throughput while maintaining small-scale precision. The core-and-sheath capability allows for printing multi-materials within a single bead, revolutionizing aerospace and marine manufacturing. 🚀 #AdditiveManufacturing #3DPrinting #Engineering #Innovation #ORNL
