3-D printing remakes the strain gauge

Rahul Panat and a team of researchers from CMU, WSU, and UT-El Paso have developed a new 3-D printing technique for manufacturing strain gauges that breaks the Poisson Ratio by 40%. Have you ever weighed your car at a weighing station on the highway? Have you ever thought about how the deflections in an airplane … Continue reading “3-D printing remakes the strain gauge”

Researchers 3D print lifelike artificial organ models

A team of researchers led by the University of Minnesota has 3D printed lifelike artificial organ models that mimic the exact anatomical structure, mechanical properties, and look and feel of real organs. These patient-specific organ models, which include integrated soft sensors, can be used for practice surgeries to improve surgical outcomes in thousands of patients … Continue reading “Researchers 3D print lifelike artificial organ models”

Engineers 3-D print a “living tattoo”

MIT engineers have devised a 3-D printing technique that uses a new kind of ink made from genetically programmed living cells. The cells are engineered to light up in response to a variety of stimuli. When mixed with a slurry of hydrogel and nutrients, the cells can be printed, layer by layer, to form three-dimensional, … Continue reading “Engineers 3-D print a “living tattoo””

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”
