Eavesdropping on 3D printers allows reverse engineering of sensitive designs

3D printers have opened up all kinds of possibilities when it comes to turning digital blueprints into real word objects, but might they also enable new ways to pilfer intellectual property? Amid all that mechanical whirring, these machines emit acoustic signals that give away the motion of the nozzle, new research has found. And by discreetly recording these sounds, scientists say it is possible for sneaky characters to deduce exact design details and reverse engineer printed objects at a later date.Read More

3D-printed braille maps to show students the way

Finding your way around an unfamiliar building can be tricky for anyone, but its far more difficult for people with visual impairments. A pair of researchers at Rutgers University School of Engineering came up with a way of improving the situation for students at a training center for the blind and visually impaired in New Brunswick by 3D-printing detailed braille maps of the facility.Read More


Review: Ultimaker 2 Extended 3D printer

In a crowded field, the Ultimaker 2 Extended is one of the highest resolution desktop 3D printers available. It's larger footprint means it can also print larger, more complex projects than many of its brethren. Gizmag tried out this jumbo making machine to size up what it can do.Read More

Used snack bags can now be recycled into whatever you design

Typical recycling involves sending off your old cans, bottles, boxes and papers to be re-purposed somewhere far away, sight unseen. Terracycle and 3D Brooklyn allow you to determine what gets made from recycled materials, thanks to a process that turns used chip and snack bags into plastic filament for use in 3D printing.Read More

3D-printed engine combustor withstands hypersonic flight testing

Aerospace 3D printing went Mach 5 this week, with Orbital ATK announcing that it has successfully tested a printed hypersonic engine combustor at NASA's Langley Research Center in Virginia. A key scramjet component, the 3D-printed combustor spent 20 days undergoing high-temperature hypersonic flight conditions as well as one of the longest duration propulsion wind tunnel tests for such a component.Read More

New 3D printing technology creates stronger ceramics

Researchers at HRL Laboratories have developed a 3D printing technology designed to overcome the limitations of working with traditional ceramic processing. The process includes a resin formulation that once printed can be fired and converted into a ceramic that is harder, stronger and more compatible with ultra-high temperatures.Read More
