3D printer produces a real gun

You’d be hard-pressed to find anyone who has anything bad to say about 3D printing. Besides having the potential to revolutionize the manufacturing industry, the machines seem to spit out one crowd-pleaser after another, objects like musical instruments, candy, toys, trinkets and even cars. But now that someone has figured out how to print out a fully-functional firearm, the technology is about to become a whole lot more controversial.
Photos of the world’s first 3D printed gun were discovered on the AR-15.com, a forum for firearms enthusiasts and supporters of gun rights. The creator, who goes by the username HaveBlue, assembled the weapon by combining the body of a normal .22 caliber pistol with that of a printed plastic version of the lower receiver used in AR-15 assault rifles (similar to the military’s M16). HaveBlue then tested out the creation by successfully firing 200 rounds without any signs of malfunction or complications, according to a post on the web site.
HaveBlue documents his gunsmithing process in such a detailed way, it might be a bit unnerving for some folks. With little more than a Stratasys 3D printer, a $30 batch of plastic resin and printing specifications available on the internet, the user was able to produce several of the necessary working parts. A step-by-step blueprint for making your own AR-15 lower receiver can also be found on Thingiverse.
While only one part of the gun was actually ”printed,” the lower receiver is the critical piece that enables the weapon to fire. It holds the bolt, trigger and the magazine, where ammunition is stored. Thats why under the American Gun Control Act, it’s this lower part that constitutes an operational gun and thus is heavily regulated.
The issue which arises now is that if anyone with a 3D printer can manufacture this part themselves or, as my previous report found, can purchase firearms freely using underground websites, what good would any form of “gun control” be?
Correction: Due to a typing error, I stated that the lower receiver ”includes the bolt, trigger and the magazine, where ammunition is stored.” That sentence has been changed to accurately state that “it holds the trigger and the magazine, where ammunition is stored.”

The 3D printer that fits into a suitcase

A pair of MIT mechanical engineering students have developed a 3D printer which certainly goes by the name of portable — fitting neatly into a standard metal suitcase.
The era of 3D printing has firmly launched — in its latest developments, being used to turn homes into drugstores, creating weapons and even being used to mold 3D replicas of your fetus –  but it’s not just about a printer’s uses, but also its features.
Most 3D printers are bulky, brick-like and the average size of a kitchen table. However, as technology evolves — consider the mobile phone as an example — the components required to maintain performance can be made smaller and more lightweight. That’s where portability comes in.
PopFab, designed by MIT students Ilan Moyer and Nadya Peek of CADLab and the Centre for Bits and Atoms respectively, can be set up within moments. The pair claim that the 3D printer has traveled the world “as a carry-on item of luggage”, and its locations include Saudi Arabia, Germany, and various parts of the United States.
Described as a multi-tool, perhaps the Swiss Army knife of 3D printers, the video below shows the two students setting up PopFab bit by bit, and is part of a series that will show off the mobile 3D printer’s capabilities.
In just a few moments, the students assembled the printer through attaching the printing head to a fold-out arm. Next, they placed the printing material and connected a computer which is used to relay the design to the machine.
In the video, the printer is used to create a small, three dimensional fish. However, the portable design could potentially be used to perform different functions — change the toolhead, switch the service. For example, the team believe it could also be used to cut vinyl, perform milling or draw programmed designs.

Clone yourself as a doll


A shop in Toyko, Japan, is offering an unsual product made possible through 3D printing -- a doll-size replica of .. yourself.
Well, at least the head.
The Clone Factory will shoot fully dimensional mages of you, input the information into programming software, and produce a replica doll-head for you through 3D printing. Apparently, these dolls are popular for weddings -- mini-me on the cake, anyone?
It will only set you back $1,800 a time.
