Is this the first 3D-printed Bullet?


A video showing what is thought to be first ever 3D-printed bullet being fired has appeared on YouTube.
In the video, from user Taofledermaus, three bullets of different weights and shapes are fired at various targets using a Mossberg 590 shotgun.

According to the video, each plastic pellet has been 3D-printed. A small lead shot was then added to give the bullet weight.

In the video, Taofledermaus is heard saying: 'You've heard of a 3D-printed gun? How about 3D-printed bullets.'
He goes on to explain that YouTube user ArtisanTony printed a 'couple of shotgun pellets' with the first weighing about four tenths of an ounce.

Owner Of Collapsed Indonesian Mine is Big Donor to Congress

By Russ Choma on May 21, 2013 8:00 AM

Last week's collapse of a massive precious metals mine in Indonesia, which killed at least 17 workers, brought unwanted attention to the American company that owns the facility, Freeport-McMoRan Copper and Gold. But the company is already well-known to many here in Washington: Its top executives, as well as the company PAC, contribute hundreds of thousands of dollars each election cycle to help fuel congressional campaigns. Freeport currently employs at least one former member of Congress as a registered lobbyist, and in the past has employed at least one other.

Freeport-McMoRan, which is based in Phoenix, strongly favors Republicans over Democrats with its contributions. In the 2012 cycle, the company's PAC and employees gave 80 percent of their $382,000 in donations to Republicans. The firm's favorite lawmaker? Arizona GOP Sen. Jeff Flake. He received the maximum $10,000 from the company PAC and another $43,000 from employees, making him the largest recipient of Freeport-McMoRan money.

Another major recipient of Freeport-McMoRan cash was David Dewhurst, who was defeated by Ted Cruz in the Republican primary for Texas' open Senate seat last year. Dewhurst, who was backed by many "establishment" Republican interests, received $10,000 from the company PAC and another $25,000 from company CEO James "Jim Bob" Moffett and members of his immediate family.

In the House, the top recipient of cash from the company is Speaker of the House John Boehner (R-Ohio), to whom the company's PAC gave the maximum of $10,000. Boehner is also one of eight members of Congress who owns shares in the company, according to his most recent personal financial disclosure form.


NASA funds design for a food replicator

By Christopher Mims

Anjan Contractor’s 3D food printer might evoke visions of the “replicator” popularized in Star Trek, from which Captain Picard was constantly interrupting himself to order tea. And indeed Contractor’s company, Systems & Materials Research Corporation, just got a six month, $125,000 grant from NASA to create a prototype of his universal food synthesizer.

But Contractor, a mechanical engineer with a background in 3D printing, envisions a much more mundane—and ultimately more important—use for the technology. He sees a day when every kitchen has a 3D printer, and the earth’s 12 billion people feed themselves customized, nutritionally-appropriate meals synthesized one layer at a time, from cartridges of powder and oils they buy at the corner grocery store. Contractor’s vision would mean the end of food waste, because the powder his system will use is shelf-stable for up to 30 years, so that each cartridge, whether it contains sugars, complex carbohydrates, protein or some other basic building block, would be fully exhausted before being returned to the store.

Ubiquitous food synthesizers would also create new ways of producing the basic calories on which we all rely. Since a powder is a powder, the inputs could be anything that contain the right organic molecules. We already know that eating meat is environmentally unsustainable, so why not get all our protein from insects?

If eating something spat out by the same kind of 3D printers that are currently being used to make everything from jet engine parts to fine art doesn’t sound too appetizing, that’s only because you can currently afford the good stuff, says Contractor. That might not be the case once the world’s population reaches its peak size, probably sometime near the end of this century.
