From Elementum 3D: Will NASA’s RAMFIRE Project Lead to an Operational Aerospike Engine?
This chronicle from Elementum 3D describes the success of NASA’s RAMFIRE project which additively manufactured a 36-inch diameter aerospike nozzle with complex integral coolant channels for a more efficient way to propel rockets to outer space. Engineers plan to use this as a proof of concept for future component designs as NASA reimagines rocket engine technology.

Army Corps of Engineers 3D Prints New Poe Lock Arrestor Arm
New Poe Lock arrestor arm is the largest U.S. civil works component produced by a 3D printer. A six-month Poe Lock closure would temporarily reduce the U.S. gross domestic product by $1.1 trillion, resulting in the loss of 11 million jobs, according to a DHS study. Faced with this challenge, advances in additive manufacturing offered transformative potential.
