World's first gun made from 3D printer successfully test-fired in US
CAD files for gun parts have been available on the Internet for some time, but the Liberator is apparently the first entire weapon ever to be fabricated almost exclusively with parts created with 3D printing technology.
WASHINGTON: Computer files to create a handgun almost entirely from parts made with a 3D printer went online Monday, alarming gun control advocates after it was successfully test-fired by its inventor. The single-shot .380-caliber Liberator bears a vague resemblance to its namesake, the FP-45 Liberator pistol that the United States developed during World War II to be air-dropped to French Resistance fighters.
Computer-aided design (CAD) files for the Liberator appeared on the website of Defense Distributed, a non-profit group that promotes the open-source development of firearms using 3D printers.
"We'll build the trigger first... Next, we'll build the hammer subassembly ... Next, drop the hammer into the frame...," reads the accompanying set of instructions, which come in English and Chinese.
"Finally slide the grip on the frame and insert the grip pin. Your Liberator is now ready to go!"
For the Liberator to conform with US firearms law, the instructions call for an inch-big chunk of steel to be sealed with epoxy glue in front of the trigger guard, so that the weapon can be spotted by metal detectors.
The only other non-plastic part is a tiny nail that acts as the firing pin.
Business magazine Forbes posted a video of the Liberator being remotely test-fired outside Austin, Texas last week, with a yellow string tied to the trigger of the toy-like white-and-blue handgun.
"The verdict: it worked," Forbes reported, adding however that the Liberator exploded ("sending shards of white ABS plastic flying into the weeds") when its inventor Cody Wilson attempted a second test using a rifle cartridge.
"I feel no sense of achievement," the 25-year-old University of Texas law student told Forbes. "There's a lot of work to be done."
CAD files for gun parts have been available on the Internet for some time, but the Liberator is apparently the first entire weapon ever to be fabricated almost exclusively with parts created with 3D printing technology.
Supporters of tougher gun laws in the United States -- where there are nearly as many guns (an estimated 300 million) as there are people (about 315 million) and more than 30,000 gun-related deaths a year -- expressed alarm.
"Stomach-churning," said Senator Charles Schumer of New York. "Now anyone -- a terrorist, someone who is mentally ill, a spousal abuser, a felon -- can essentially open a gun factory in their garage. It must be stopped."
In the House of Representatives, Congressman Steve Israel, also from New York, is sponsoring an Undetectable Firearms Modernization Act to outlaw plastic homemade guns.
"Security checkpoints, background checks, and gun regulations will do little good if criminals can print plastic firearms at home and bring those firearms through metal detectors with no one the wiser," he said in a statement.
No longer prohibitively expensive, 3D printers can now be bought for about the same price as a top-end laptop computer. Brooklyn-based MakerBot, for instance, markets its desktop Replicator 2 for $2,199 with delivery in a week.
After the December 2012 massacre of 20 children at Sandy Hook elementary school in Newtown, Connecticut, MakerBot took down CAD files for semi-automatic rifle parts that gun enthusiasts had posted on its open-source 3D printing library.

Childhood rape can cause genetic changes: Study


NEW DELHI: Childhood rape or other traumatic events like car accidents or recurrent abuse can change the genetic functioning of the victim, a new study led by Divya Mehta of the Max Planck Institute of Psychiatry in Munich, Germany, has found.
Comparing the genetic structure of blood cells drawn from childhood abuse victims with that of persons who had not suffered such abuse, the researchers found that changes in the genes were 12 times more visible in the abused persons. These are called epigenetic changes - the DNA has not changed but there are chemical differences that affect the way the genes do their work. Epigenetic changes are caused by outside circumstances and usually last lifelong.
The study has been published in a recent issue of the scientific journal Proceedings of National Academy of Science (PNAS). Scientists from Emory University and the Howard Hughes Medical Institute also participated in the research
Mehta and her colleagues studied 169 persons in their late thirties or early forties. They had suffered from seven traumatic events on an average including rape, being held at knife-point, going through a car accident, etc. While a majority of them (108) had got over the trauma, 61 were suffering from post traumatic stress disorder (PTSD), a condition where they experienced an extreme anxiety disorder arising from the traumatic event. Of the PTSD patients, 32 had suffered childhood abuse while 29 had not.
"These results show that while these patients have similar or even indistinguishable symptoms on the outside, they are very different on the inside. The molecular mechanism and biological pathways altered among the two sets of patients are distinct," Mehta told TOI.
"Trauma/abuse which occurs very early in life leaves long-lasting epigenetic marks on the genome as compared to trauma which occurs later in life," she added.
This discovery radically changes the way victims of trauma need to be looked at. Not just the symptoms but the path leading to the disease - timing, type of trauma and the preexisting genetic risk factors) are all important according to Mehta.
The research also has major implications for wider psychiatric treatment. One of the reasons why psychiatric treatment has a low success rate could be that patients with different 'biologies', that is, internal genetic structures are all being grouped under one disease, Mehta said.
The study shows that in the future, trauma victims will need to be first checked through blood markers whether they have childhood trauma changes - this will open the door to better more effective customized treatment.
