3-D printed metallic gun could shoot $33B firearm industry in the foot

Solid Concepts, a small prototyping company that helps gun manufacturers identify problems with their designs in pre-production, yesterday unveiled what they believe is the first ever 3-D printed gun made of metal. That could be bad news for the $33 billion United States firearms industry.

“The intent wasn’t to build a gun for sale it was a technology proving exercise,” said Solid Concepts’ vice president Scott McGowan in an interview with Upstart Business Journal this afternoon. And for existing gun manufacturers he said it “just wouldn’t make sense” for them to switch to 3-D printing.

But what it does do is lower the barrier to entry for entrepreneurs who want to get into the gun manufacturing business.

McGowan said the $750,000 printers can produce one to three model 1911 guns per day. The same model on Smith and Wesson’s site sells for roughly $1,000 per gun. A hard-to-find tailor-made gun part could be printed and delivered in five days—which should catch the attention of the $33 billion sporting arms and ammunition industry employs 220,000 full-time Americans.

A federally licensed firearms manufacturer, Solid Concepts designed their version of the publicly available 3-D printed 1911 handgun to show that 3D printing is a viable competitor to existing manufacturing techniques.

As more people buy the machines and the technology itself gets cheaper to produce thanks to Moore’s Law, the price to enter the gun manufacturing business will only come down.

Based in Valencia, California the company printed the weapon using a direct metal laser sintering (DMLS) process in which metal powder is heated to create what can be thought of as “ink” for the printer. They also have 80 other “additive” machines that print in other materials.(Source (http://upstart.bizjournals.com/news/technology/2013/11/08/solid-concepts-builds-3-d-printed-gun.html))

Ranging from light alloys via steels to super-alloys and composites, that’s a bad a$$ machine.

I thought the DPD officer questioned on camera by Fox4 last night did a very good job of explaining the Castle Doctrine. He slipped it into his explanation of the incident. Almost like he sensed there were citizens unaware of its existence.

A castle doctrine (also known as a castle law or a defense of habitation law) is a legal doctrine that designates a person's abode (or, in some states, any legally occupied place [e.g., a vehicle or workplace]) as a place in which that person has certain protections and immunities permitting him or her, in certain circumstances, to use force (up to and including deadly force) to defend themselves against an intruder, free from legal responsibility/prosecution for the consequences of the force used.[1] Typically deadly force is considered justified, and a defense of justifiable homicide applicable, in cases "when the actor reasonably fears imminent peril of death or serious bodily harm to him or herself or another".[1] The doctrine is not a defined law that can be invoked, but a set of principles which is incorporated in some form in the law of many states.

The legal concept of the inviolability of the home has been known in Western Civilization since the age of the Roman Republic.[2] The term derives from the historic English common law dictum that "an Englishman's home is his castle". This concept was established as English law by the 17th century jurist Sir Edward Coke, in his The Institutes of the Laws of England, 1628:[3] http://en.wikipedia.org/wiki/Castle_Doctrine
