Making telescopes that curve and twist

Making telescopes that curve and twist
Posted: Jul 11, 2017 (Nanowerk News) A new tool for computational design allows users to turn any 3D shape into a collapsible telescoping structure. New mathematical methods developed by researchers at Carnegie Mellon University capture the complex and diverse properties of such structures, which are valuable for a variety of applications in 3D fabrication and robotics--particularly where mechanisms must be compact in size and easily deployable. The re…

Unique 3-D printed models could improve patient outcomes in heart valve replacements

Unique 3-D printed models could improve patient outcomes in heart valve replacements
Posted: Jul 07, 2017 (Nanowerk News) Researchers at Georgia Institute of Technology and the Piedmont Heart Institute are using standard medical imaging and new 3-D printing technologies to create patient-specific heart valve models that mimic the physiological qualities of the real valves. Their aim is to improve the success rate of transcatheter aortic valve replacements (TAVR) by picking the right prosthetic and avoiding a common complication known as paravalvular l…

3D printing: a new industrial revolution

3D printing: a new industrial revolution
Posted: Jul 06, 2017 (Nanowerk News) A just published article on 3D printing ("3D Printing and Additive Manufacturing – The Implications for OSH"; pdf) has been undertaken on behalf of the European Agency for Safety and Health at Work (EU-OSHA). It examines some key questions concerning the opportunities and challenges of the emerging 3D printing industry for employers, workers and the new entrepreneur, who is working from home or informal workspaces.…

3D-printed robot enters battle against cancer (w/video)

3D-printed robot enters battle against cancer (w/video)
Posted: Jul 03, 2017 (Nanowerk News) The Stormram 4, as the robot is named, is made from 3D-printed plastic and is driven by air pressure. The advantage of plastic is that the robot can be used in an MRI scanner. Carrying out a biopsy (removing a piece of tissue) during a breast cancer scan in an MRI significantly increases accuracy. The robot won a prestigious award during the Surgical Robotic Challenge at the international Hamlyn Symposium in London…

Risk assessment of 3D printers and 3D printed products

Risk assessment of 3D printers and 3D printed products
Posted: Jun 29, 2017 (Nanowerk News) An increasing number of private consumers buy 3D printers and install them at home. Likewise, private consumers can make 3D printed products at several institutions (e.g., libraries) and shops, or order 3D printed products via websites. The project assessed the risk involved when using 3D printed products. The assessment ("Risk Assessment of 3D Printers and 3D Printed Products"; pdf) was based on results from a numb…

Researchers create 3D-printed tensegrity objects capable of dramatic shape change

Researchers create 3D-printed tensegrity objects capable of dramatic shape change
Posted: Jun 14, 2017 (Nanowerk News) A team of researchers from the Georgia Institute of Technology has developed a way to use 3-D printers to create objects capable of expanding dramatically that could someday be used in applications ranging from space missions to biomedical devices. The new objects use tensegrity, a structural system of floating rods in compression and cables in continuous tension. The researchers fabricated the struts from shape mem…

3-D-printed patch helps guide growing blood vessels

3-D-printed patch helps guide growing blood vessels
Posted: Jun 13, 2017 (Nanowerk News) Ischemia results when narrowed, hardened or blocked blood vessels starve tissue, often resulting in heart attack, stroke, gangrene and other serious conditions. Surgery can correct the problem in large vessels, but treatment is much more complex in vessels that are smaller or damaged by prior treatment. Professor Christopher Chen (BME, MSE) is developing a method using 3D-printed patches infused with cells that offer a promising ne…

3D printing breakthrough heralds 'new era' for advanced skin models

3D printing breakthrough heralds
Posted: Jun 12, 2017 (Nanowerk News) Scientists in South Korea have come up with a new method for 3D printing human skin, which both shortens the process and reduces the cost. Reporting their results today in the journal Biofabrication ("Direct 3D cell-printing of human skin with functional transwell system"), the team from Pohang University of Science and Technology demonstrate a new 3D cell printing strategy, for engineering a 3D human skin model in …

New technique enables 3-D printing with paste of silicone particles in water

New technique enables 3-D printing with paste of silicone particles in water
Posted: Jun 07, 2017 (Nanowerk News) Using the principles behind the formation of sandcastles from wet sand, North Carolina State University researchers have achieved 3-D printing of flexible and porous silicone rubber structures through a new technique that combines water with solid and liquid forms of silicone into a pasty ink that can be fed through a 3-D printer. The finding could have biomedical applications and uses in soft robotics. In a paper p…

A 3D-printed rocket engine just launched a new era of space exploration

A 3D-printed rocket engine just launched a new era of space exploration
Posted: May 30, 2017 (Nanowerk News) The rocket that blasted into space from New Zealand on May 25 was special. Not only was it the first to launch from a private site, it was also the first to be powered by an engine made almost entirely using 3D printing. This might not make it the “first 3D-printed rocket in space” that some headlines described it as, but it does highlight how seriously this manufacturing technique is being taken by the space industry. …
