ORNL’s Modular Multi-Extruder System Unlocks Higher Speed and Multi-Material Printing

by

Researchers at Oak Ridge National Laboratory (ORNL), US Department of Energy’s largest multi-program science and energy laboratory, have developed a modular 3D printing extrusion system that increases throughput without adding tool weight. The system merges multiple smaller extruders into a single material stream using specialized nozzle blocks, enabling adjustable output, precise deposition, and multi-material printing … Read more

US tests nuclear fuel for rockets to take humans to Mars, deep space

by

Space agencies and private companies have set a bold target to send humans to the distant red planet, Mars. Nuclear Thermal Propulsion (NTP) is actively being explored for faster long-distance space travel. This could make crewed missions more feasible and safer.  However, this technology comes with its challenges. NTP engines demand materials that can survive extreme … Read more
