First 3-D-Printed Metal Gun Shows Tech Maturity – IEEE Spectrum.

Direct Metal Laser Sintering (DMLS) (video description) used to print the bulk of this gun and its parts in steel.

The printer required to do this costs $10000 today.

“Called 2Seas, the UAV is designed to fly lengthy surveillance missions for coastguards in the UK, the Netherlands, Belgium and France. It is a direct descendant of the catapult-launched, 1.5-metre-wingspan, electric-powered SULSA (Southampton University Laser Sintered Aircraft) – the world’s first all-3D-printed drone, built at the University of Southampton, UK. SULSA’s first flight was exclusively revealed by New ScientistMovie Camera in August 2011.”

3D printed battery

3D printed battery! It’s all coming together 😉

Nanoparticle Ink Enables 3-D Printing of Microbattery Electrodes – IEEE Spectrum.

60,000 RPM vacuum powered rotary tool was 3D printed.

All the instructions are on Thingiverse. The bearings and central shaft are metal and much harder to make.
