At the World Economic Forum (WEF) in Davos a key topic is focusing on the "Digital Transformation of Industries”. The fourth industrial revolution is imminent. It goes by the name “Industry 4.0” and is expected to fundamentally change, among other things, the production methods and business models currently used in industrialized countries.
A group of researchers at ETH Zurich have developed an advanced 3D microprinting method, that can be utilized to develop small, intricate, overhanging metal structures in just one simple step. This latest technique holds potential for designing a wide range of microtools, such as tools for keyhole surgeries and complicated components for watches.
With his idea for 3-D-printed, custom-fit activewear, Eric Beaudette ’16 hopes professional young men can go from the workplace to the gym without breaking a sweat.
Esophageal cancer is the eighth most common form of cancer worldwide and treatment of this disease continues to be a major medical challenge. Despite improvements in surgical techniques, 50 to 60 percent of patients with esophageal cancer are not suitable for surgery, because of late tumor detection or metastases that cannot be removed with surgery.
The study exhibits a unique method, using ultrasonic waves to accurately position a huge number of tiny reinforcement fibers as part of the 3D printing process. The fibers form a microscopic reinforcement framework to provide the material strength, a focused laser beam is then used to position this microstructure. Finally, the epoxy resin is cured and the object is printed.
Engineers from Northwestern University have created a new technique to print 3D metallic objects without relying on metal powder beds, and expensive electron beams or lasers. This technique is fast, cheap, and provides a more uniform process, utilizing common furnaces and liquid inks. The research team also demonstrate that the new method could be used for a varied range of metals, alloys, metal mixtures, compounds, and metal oxides.
The University of Tsukuba in conjunction with Dai Nippon Printing Co., Ltd. (DNP) have successfully developed a low cost human organ model production technique for use with 3D printers that helps reveal complicated interior organ structure.
German industrial machining and tooling equipment manufacturer, Trumpf, has added another type of metal 3D printing technology to its portfolio.
A researcher at the University of California, Riverside (UC Riverside) is using 3D printing technology to gain a better insight into the formation of galaxies and the evolution of the universe and its cosmic structures.
Only a few days after announcing the expansion of its technological range of industrial machines for selective laser sintering of polymers and related materials, Prodways Group announces the launch of its Aerospace division.
