    3D printed organ transplants have been in the cards for a while, but deep tissue printing has proved problematic. Now a team of scientists in Korea think they have cracked the code for producing functional liver tissue by printing functional mouse liver cells. Simply put, we need more livers than we currently have as hepatitis, cirrhosis and liver cancer are increasingly prevalent. The donor system, meanwhile, is inherently flawed. Patients face agonising treatment while they wait for a suitable liver. There is simply no guarantee they will get a matching organ in time and even if they do, there can...
  • 3-D Printed Ceramics Could Build Next-Gen Spaceships

    Schaedler and colleagues at HRL invented a resin formulation that can be 3-D printed into parts of virtually any shape and size. The printed resin can then be fired, converting it into a high strength, fully dense ceramic. The resulting material can withstand ultrahigh temperatures in excess of 1,700 degrees Celsius (3,092 Fahrenheit) and is 10 times stronger than similar materials. Ceramics are much more difficult to work with than plastics or metals because they cannot be cast or machined easily, according to Schaedler, who is an author on the new study appearing today in the journal Science. But Schaedler's...

    Shortage of organs for transplantation has been one of the most challenging endeavor that patients, families and health care providers face today. But now, a possible novel answer to organ shortage has arrived: 3D printing of substitute organs. Numerous measures have been implemented to widen the pool of organ donors all across the U.S. Interventions to address the problem of organ shortage include national programs to heighten deceased donor donation, paired donor exchanges and split organ donation, among many others. Actions to hasten public awareness, enhance efficiency of donation mechanism and standardize donation policies have resulted in remarkable rates of...

Construction of the habitat would be begin with a long pole that would drill into the ground and from which two robotic arms would extend. One arm would suck up and sort material from the surface, while the other one would use the material to construct a dome overhead. Printed from Martian soil, the home is partially buried underground so that only the top floor is on the surface. In this space, the astronauts could maintain an indoor garden and workspace. The...

    Laura Bosworth wants to 3D print breast nipples on demand. The CEO of the Texas startup TeVido Biodevices is betting on a future in which survivors of breast cancer who have undergone mastectomies will be able to order up new breasts printed from their own living cells. “Everyone,” she says, “knows a woman who has had breast cancer.” Right now their options are limited. Reconstructed nipples using state-of-the-art plastic surgery techniques, she says, “tend to flatten and fade and don’t last very long.” A living nipple built from the patient’s own fat cells, and reconstructed to the precise specification of...

    Harvard scientists have developed a new bioprinting method that can create intricately patterned 3-D tissue constructs with multiple types of cells and tiny blood vessels. The work is a major step toward creating human tissue constructs realistic enough to test drug safety and effectiveness, researchers said. The method will also help bring closer the building of fully functional replacements for injured or diseased tissue that can be designed from CAT scan data using computer-aided design (CAD), printed in 3D at the push of a button. "This is the foundational step toward creating 3D living tissue," said Jennifer Lewis, senior author...

    A homemade submachine gun Obtaining a gun without a background check in the United States (and much of the world) is a fairly easy process, and is becoming easier all the time. Here are some of the common methods of obtaining a gun without a background check. 1. Have someone who can pass the background check buy it for you. This is illegal to do for someone who is forbidden from possessing guns. It is known as a straw purchase. The BATFE says that it is the most common method for criminals to obtain guns. In most states it...
  • 3D Printed Gun: Mashable Mini-Documentary

    Recently we’ve been featuring occasional prints of the Liberator (and will also have other 3D printed guns soon-ish). One of the Liberators we showed you was printed on the 3D Systems Cube in blue plastic. We didn’t name the guy who did it, but he’s Travis Lerol. The website Mashable did a nice mini-documentary in which they interview the media-happy Cody Wilson, and accompany Lerol to the first attempted live fire of his Liberator. Travis, an Air Force vet, comes across as an engaging geek (along with the Liberator and several AR-15 lower iterations, he’s printed a scale-model TARDIS, from...

    "Significant advances in three-dimensional (3D) printing capabilities, availability of free digital 3D printer files for firearms components, and difficulty regulating file sharing may present public safety risks from unqualified gun seekers who obtain or manufacture 3D printed guns," warns the bulletin compiled by the Joint Regional Intelligence Center. The bulletin refers specifically to Defense Distributed, a nonprofit company started by a University of Texas law student, which has successfully made and fired a 3D gun whose only metal parts are the bullets and a small firing pin. Some 100,000 plans for a gun called "The Liberator" were downloaded in just...

    3D Printer-extraordinaire WarFairy has expanded his P90-styled Charon printable AR-15 lower from a single design into an entire line of printable rifle and pistol lowers.The original Charon receiver design has been upgraded to version 0.2. The updated model features a thicker magazine well with a finger hook (I am sure someone more knowledgable than I can explain in the comments below what finger hooks are for … ).The most exciting new addition to the Charon line is the Carbine, Adjustable Stock. The stock on this model slides out from under the buffer tube to adjust the length of pull. The length of pull is adjustable...

    Image from Defense Distributed The DEFCAD community has released an upgraded version of the Defense Distributed Liberator 3D printed pistol. As they are individuals on the Internet and not an organization, they have never received a letter from any government entity asking them not to distribute computer files.Improvements include barrels for the .25 ACP cartridge and for the .45 ACP cartridge. No information was supplied to determine if any test firing of these cartridges has been done. I suspect that the .25 ACP version would work, but I have doubts about the .45 ACP barrel. While the working pressures are...

    Image from Defense DistributedAustralian police in New South Wales have printed out two versions of the liberator 3D printed pistol and tested them to destruction. No technical details of the testing were released, just videos of the guns blowing up. The video does not show any cartridges used, nor does it detail the type of plastic used. These are critical elements for anyone trying to actually understand what happened. Without this information, the video is just political theater, propaganda designed to frighten timid people away from this technology. Compare the test fire shown in the New South Wales video with...

    When high tech gunsmith group Defense Distributed test-fired the worlds first fully 3D-printed firearm earlier this month, some critics dismissed the demonstration as expensive and impractical, arguing it could only be done with a high-end industrial 3D printer and that the plastic weapon wouldnt last more than a single shot. Now a couple of hobbyists have proven them wrong on both counts.One evening late last week, a Wisconsin engineer who calls himself Joe test-fired a new version of that handgun printed on a $1,725 Lulzbot A0-101 consumer-grade 3D printer, far cheaper than the one used by Defense Distributed. Joe, who...

    DD ITAR Update 1 A few have criticized how quickly I responded to the DDTC and began participating in their regulatory process. It is said I should have stood and fought if I believed in keeping the files free, instead of complying. This compliance has been viewed as some kind of ultimate one, as if I dont intend to do anything else. No takedowns, ever. Was a motto I had built into my vision of, not, and it referred to a strategy for dealing with intellectual property claims and social pressure- this is NOT the strategy DD/ can...

    (snip) Similarly, honest citizens should not have a general obligation to disclose to the government what firearms theyve built or bought, provided they are for honest purposes. An honest person may wish to keep this information private to avoid becoming the target of thieves or unwanted political attacks. A desire for private firearms ownership is not proof of criminal intent. And if the government has a specific concern that someone is planning a crime with a gun (or any other tool), the burden of proof should be on the government prior to any search or other invasion of his privacy....
