Defeating Cyberattacks on 3D Printers

Rutgers University and Georgia Tech engineers have devised three ways to combat cyberattacks on 3-D printers: monitoring printer motion and sounds and using tiny gold nanoparticles. 3D Printers will be attractive targets because 3D-printed objects and parts are used in critical infrastructures around the world, and cyberattacks may cause failures in health care, transportation, robotics, … Continue reading “Defeating Cyberattacks on 3D Printers”

A new method of 3D printing living tissues

Scientists at the University of Oxford have developed a new method to 3D-print laboratory-grown cells to form living structures. The approach could revolutionise regenerative medicine, enabling the production of complex tissues and cartilage that would potentially support, repair or augment diseased and damaged areas of the body. In research published in the journal Scientific Reports, an … Continue reading “A new method of 3D printing living tissues”

NVBOTS is making 3-D printing as simple as printing on paper

If you haven’t used a 3-D printer yet, you may be surprised to learn that it isn’t fully automated the way your office’s inkjet is. With paper printers, users queue documents from a computer, and each finished sheet drops neatly into a tray, waiting to be collected. With commercial 3-D printers, however, designs are manually … Continue reading “NVBOTS is making 3-D printing as simple as printing on paper”

3D-printing Bricks using Moondust and Sun’s Heat.

Bricks have been 3D printed out of simulated moondust using concentrated sunlight. This ESA project took place at the DLR German Aerospace Center facility, with a 3D printer table attached to a solar furnace, baking successive 0.1 mm layers of moondust at a temperature of 1000°C. A 20 x 10 x 3 cm brick for … Continue reading “3D-printing Bricks using Moondust and Sun’s Heat.”

New 3-D Printing Method Creates Shape-Shifting Objects

A team of researchers from Georgia Institute of Technology and two other institutions has developed a new 3-D printing method to create objects that can permanently transform into a range of different shapes in response to heat. The team created the objects by printing layers of shape memory polymers with each layer designed to respond … Continue reading “New 3-D Printing Method Creates Shape-Shifting Objects”
