Always one to push the envelope, U.S. Army researchers from the U.S. Army Armament Research, Development and Engineering Center (ARDEC) have been successfully experimenting with 3D printing for one of their latest technologies. The result? RAMBO — Rapid Additively Manufactured Ballistic Ordinance — a 40mm grenade launcher. Fitting name, no?
Virtually the entire gun was produced using additive manufacturing while some components — ie: the barrel and receiver — were produced via direct metal laser sintering (DMLS). So, 3D printed rounds fired from a 3D printed launcher with the only conventionally manufactured components being springs and fasteners, all within a six month development time.

If you’re tired of underhanded deals going down behind closed doors maybe you need to start carrying around this transparency grenade. The enclosure is modeled after a Soviet-era F1 Hand Grenade. But it’s not filled with explosives and won’t send deadly shrapnel around the room. Instead, when the pin is pulled it starts recording audio and sniffing network packets, then broadcasts both to a remote server. Perhaps you could consider this to be data shrapnel sent around the world.
The exploded parts image above shows what hardware is at use. There’s a Gumstix board at the heart of the device which uses a WiFi module for sniffing and broadcasting data. The LED bar graph which you see in the fully assembled unit shows the wireless signal strength.
It sounds like the enclosure itself was 3D printed from Tusk2700T translucent resin but we’re a little confused by this part of the hardware description. We don’t have much of a need to transmit recordings of our meetings, but we’d love to use this case design for that MP3 enclosure.
