Joining Forces: Fast-as-lightning 3D Microprinting with Two Lasers

Printing objects from plastic precisely, quickly, and inexpensively is the goal of many 3D printing processes. However, speed and high resolution remain a technological challenge. A research team from the Karlsruhe Institute of Technology (KIT), Heidelberg University, and the Queensland University of Technology (QUT) has come a long way toward achieving this goal. It developed a laser printing process that can print micrometer-sized parts in the blink of an eye. The international team published the work in Nature Photonics. (DOI: 10.1038/s41566-022-01081-0)

Pitt is the only university in the U.S. with this giant 3D printer for metal

The University of Pittsburgh is in exclusive company with a new state-of-the-art technology — the first Gefertec arc605 3D printer at any university in the U.S, thanks to funding from the Department of Energy and U.S. Army. The printer makes use of welding, melting wire made from metals like stainless steel, titanium and aluminum alloys and depositing it layer by layer. Pitt’s new Gefertec arc605 is much faster than previous metal 3D printers, which used lasers and metal powder.

Pain in the Neck? New Surgical Method Could be Game-changing

Anterior cervical discectomy and fusion is widely used to treat spinal disorders. The fusion involves placing a bone graft or “cage” and/or implants where the surgically removed damaged disc was originally located to stabilize and strengthen the area. The risk factors for cage migration are multifactorial and include patient, radiological characteristics, surgical techniques and postoperative factors. A study is the first to evaluate the effect of the range of motion, cage migration and penetration using variable angle screws and cervical spine models. The plate developed and tested by the researchers provided directional stability and excellent fusion, showing promising clinical outcomes for patients with degenerative cervical spine disease.

Now We’re Cooking with Lasers

Imagine having your own digital personal chef; ready to cook whatever you want, tailoring the shape, texture, and flavor just for you–all at the push of a button. Columbia engineers have been working on doing just that, using lasers for cooking and 3D printing technology for assembling foods. In their new study they discovered that laser-cooked meat shrinks 50% less, retains double the moisture content, and shows similar flavor development to conventionally cooked meat.

Nuclear reactor components 3D printed by ORNL now installed at TVA Browns Ferry nuclear plant

UCI materials scientists discover design secrets of nearly indestructible insect

Irvine, Calif., Oct. 21, 2020 – With one of the more awe-inspiring names in the animal kingdom, the diabolical ironclad beetle is one formidable insect. Birds, lizards and rodents frequently try to make a meal of it but seldom succeed. Run over it with a car, and the critter lives on. The beetle’s survival depends on two key factors: its ability to convincingly play dead and an exoskeleton that’s one of the toughest, most crush-resistant structures known to exist in the biological world.
