Check out the latest news report of our recent work to create multilayered metasurface structures by nanoimprint lithography. https://lnkd.in/gk9DHi-k This work was gererously supported by the SETO office within the Department of Energy, built upon our close collaboration with Prof. Yu(宇) Yao(姚) and made possible by hard work of great PhD students Dr. Jiawei Zuo and Shinhyuk Choi over the past few years. Here we demonstrate a new way to make use of nanoimprint’s capability as a 3D pattern transfer technology to create a mold replica of nano structures that functions as a scaffold for a double-layer coupled metal gratings . This grating layer, acting as a polarizer, stacks precisely through Moiré alignment on top of another layer of Silicon based metasurface, acting as a wave plate, to complete a polarimetric multilayer metasurface device. We prove it is possible to get millimeter to centimeter scale printing, high uniformity, and a high performance of polarization selection and Stokes parameter analysis.

Just printed 0.1 mm thick surface on a powder based 3d printer!It’s amazing how this revolutionary technology is changing what was once considered impossible or required extensive post-processing. Although not perfect, a little modification on geometry can make it much better. #3DPrinting, #AutodeskTechnologyCenter, #SLS and #Technology.

#Selectivelasersintering simply does not get better than #finedetailresolution #FDR on the #FormigaP110FDR edition, from the global #SLS leaders at EOS. Read up on the detailed article by Tess Boissonneault to learn about all the possibilities that "stereolithography-level" precision with #thermoplastics via SLS #3Dprinting can enable.

Only 750 microns. That is the size of a single fine salt grain. It’s amazing how 3D printing has evolved. #3DPrinting #Lithography

This video briefly showcases our work on the simulation of Material Extrusion 3D printed components by using Bond Based Peridynamics, along with an evaluation of the nonlinear behavior of produced sample with modelling. Thanks to my supervisors, Ugo Galvanetto and Mirco Zaccariotto for their support and guidance throughout this project. #MaterialExtrusion #3DPrinting #Peridynamics

Just came across a fascinating video that showcases a groundbreaking development in 3D printing technology. An independent engineer has introduced the TIME system (True Independent Multiple Extrusion), a revolutionary approach that enables multiple tools to operate independently across all axes. This innovation opens up new possibilities, like printing with diverse materials in a single job or precisely adjusting an object’s weight or center of gravity. What captivates me isn't just the technology but the journey of creativity and problem-solving that brought this idea to life. From using a grill plate as a makeshift printer base to navigating through numerous engineering challenges, it's a testament to how passion and persistence can lead to groundbreaking innovations. I believe sharing and discussing cutting-edge developments like this not only fuels our collective imagination but also pushes the boundaries of what's possible in our fields. How do you see this impacting the future of 3D printing and design? How else could this concept be explored? #3DPrinting #Innovation #Engineering #FutureTech https://lnkd.in/eUBUh_sk

In additive manufacturing, continuous innovation plays a pivotal role in overcoming challenges and optimizing processes. 3D printed wax casting, widely embraced across various industries, serves as a cornerstone for intricate and detailed patterns, especially in the realms of luxury and jewelry. However, the fragility of these components and the conventional methods of wax support removal have long posed challenges, demanding skilled technicians and often resulting in low productivity. The solution? Our SVC technology series of automated post-processing solutions. Groundbreaking chemistry is paired with intelligent software and innovative hardware, ensuring that wax 3D-printed parts are uniformly processed. This not only enhances precision finishing but also addresses concerns related to fragility and breakage. Check out the transformative power of automated post-processing in our End Game video. #postprocessing #wax #3dprinting #jewelry3dprinting
