Three months ago, the gunsmiths behind the group known as Defense Distributed announced their intention to create a working, lethal gun anyone can download and 3D-print at home. Now their experiments with actual 3D-printed firearm components and live ammunition have started. And they’re documenting their progress on video.
“We believe this report strongly supports our view that the biggest problem for cyclists is bad driving,” he continued. “With that in mind we are greatly concerned that the government still seems fascinated with analysing and promoting cycle helmets, the value of which appears to be inconclusive.
“We believe that the government should now focus on tackling the causes of injury which appears to be mainly inconsiderate and dangerous driving. Reduced speed limits, stronger traffic law enforcement and cycle-friendly road design are the solutions.”
Steel beams are pretty uniformly strong, but they’re all run of the mill, literally. If you start 3D-printing custom beams for the exact purpose they’re intended to serve though, you’ve got a regular space-age material on your hands. It’s lighter than steel and orders of magnitude stronger.
