 | New NASA dry tech mimics extreme cold of lunar night
To build its lunar South Pole base, NASA must first understand how materials handle extreme temperature swings. Engineers at Glenn Research Center invented the Lunar Environment Structural Test Rig. It replaces expensive, hazardous liquid cryogens with a "dry" mechanical vacuum, and it's a huge leap forward.

| | Videos+: Technologies and inspiration in action | Radio Flyer cuts ebike prototype time radically with Fuse X1 large-format SLS 3D printer
Radio Flyer cut prototype lead times for its Flyer Loop cargo ebike frame from two months to two days using Formlabs' new Fuse X1 SLS large-format 3D printer. "We can now print an entire Flyer Loop cargo ebike overnight and be gluing it together the next day," said Agostino LoBello, product development engineer at Radio Flyer. "I can iterate three times as often with nine times less labor." The Fuse X1 delivers production-quality parts with 50% lower costs and triple the throughput of comparable industrial systems, featuring automated powder handling and a compact, easy-to-install design.
