Rice researchers use 3-D printers to turn century-old theory into complex schwarzites

Rice University engineers are using 3-D printers to turn structures that have until now existed primarily in theory into strong, light and durable materials with complex, repeating patterns. The porous structures called schwarzites are designed with computer algorithms, but Rice researchers found they could send data from the programs to printers and make macroscale, polymer models for … Continue reading “Rice researchers use 3-D printers to turn century-old theory into complex schwarzites”

Lab researchers achieve breakthrough in 3D printed marine grade stainless steel

Marine grade” stainless steel is valued for its performance under corrosive environments and for its high ductility — the ability to bend without breaking under stress — making it a preferred choice for oil pipelines, welding, kitchen utensils, chemical equipment, medical implants, engine parts and nuclear waste storage. However, conventional techniques for strengthening this class … Continue reading “Lab researchers achieve breakthrough in 3D printed marine grade stainless steel”

3-D-printed device builds better nanofibers

A 3-D-printed manufacturing device can extrude fibers that are only 75 nanometers in diameter, or one-thousandth the width of a human hair. Meshes made from fibers with nanometer-scale diameters have a wide range of potential applications, including tissue engineering, water filtration, solar cells, and even body armor. But their commercialization has been hampered by inefficient … Continue reading “3-D-printed device builds better nanofibers”

3D printer makes first wearable ‘battery’

Imagine printing off a wristband that charges your smartphone or electric car with cheap supplies from a local hardware store. That’s the direction materials research is heading at Brunel University London where scientists have become the first to simply and affordably 3D print a flexible, wearable ‘battery’. The technique opens the way for novel designs … Continue reading “3D printer makes first wearable ‘battery’”

HRL Engineers 3-D print high-strength aluminum, solve ages-old welding problem using nanoparticles

HRL Laboratories has made a breakthrough in metallurgy with the announcement that researchers at the famous facility have developed a technique for successfully 3D printing high-strength aluminum alloys—including types Al7075 and Al6061—that opens the door to additive manufacturing of engineering-relevant alloys. These alloys are very desirable for aircraft and automobile parts and have been among … Continue reading “HRL Engineers 3-D print high-strength aluminum, solve ages-old welding problem using nanoparticles”
