3D Printing

Manufacture what you want by 3D printer. I'm not kidding it's seriously true!!!!!
Additive manufacturing or 3D printing is a process of making three dimensional solid objects from a digital model. 3D printing is achieved using additive processes, where an object is created by laying down successive layers of material. 3D printing is considered distinct from traditional machining techniques (subtractive processes) which mostly rely on the removal of material by drilling, cutting etc.
3D printing is usually performed by a materials printer using digital technology. Since the start of the twenty-first century there has been a large growth in the sales of these machines, and their price dropped substantially.
The technology is used in the fields of jewellery, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and many others.
Additive manufacturing (AM) also known as 3D printing is defined by ASTM as the "process of joining".
NASA is set to launch world’s first zero-G-ready 3D printer into space next year, during its resupply mission to the International Space Station, so that parts can be built on-demand in space.

First 3D Printed Rifle Worked Successfully


A riflemaker in Canada has made and tested what he says is the world's first 3D-printed rifle. He follows gunsmith Cody Wilson who fired the first 3D-printed handgun earlier this year.
When the riflemaker, known as "Matthew," first fired the .22-caliber rifle, the gun cracked after the first shot. Now, the rifle, known as the "Grizzly," is back and better than ever, according to Matthew, who furnished the rifle with a thicker barrel.
Matthew managed to fire 14 shots before the plastic around the barrel cracked. When first testing the rifle, Matthew can be seen using a string to pull the trigger from a distance. Now, he seems confident enough to pull the trigger by hand.
To reload the gun, Matthew has to pull the barrel off and use a stick to dislodge the spent shell casing, then load another round and reassemble the rifle.
3D-printed guns have inspired increased debate on the availability of blueprints for such weapons. Cody Wilson, the creator of the "Liberator," posted the gun's blueprints online for anyone to access. Since then, 3D printers have made improvements and tweaks to those blueprints.
Defense Distributed, Wilson's nonprofit organization, claims to have the plans for the lower receiver of an AR-15 semi-automatic rifle, the portion of the civilian rifle that’s classified as a weapon.
