The US Air Force is completing its evaluation of 3D-printed microvanes designed to reduce drag on C-17 Globemaster III transport aircraft. These small blade-like components, measuring 4 x 16 inches, are installed at the rear of the aircraft’s fuselage using adhesive. The modification aims to decrease drag by one percent and improve fuel efficiency. Testing of the microvanes concluded in October 2023, with trials including assault strip and air refueling operations. The first C-17 equipped with these devices is currently stationed at Stewart Air National Guard Base in New York, where it has been operating successfully for over a year, including deployment missions.

Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) and the University of Maine have developed a groundbreaking single-piece, recyclable natural-material floor panel through advanced 3D printing techniques. This novel panel, designed to substitute traditional steel in construction, was unveiled at the U.S. Department of Housing and Urban Development’s 2024 Housing Innovation Showcase on the National Mall. The project is a key initiative under the Sustainable Materials & Manufacturing Alliance for Renewable Technologies (SM2ART) program, which focuses on creating environmentally friendly construction solutions. The SM2ART Nfloor cassette panel represents a significant advancement in building construction, particularly for apartment and condominium structures. By replacing conventional steel-and-concrete assemblies, the panel offers a sustainable alternative that maintains structural integrity while reducing environmental impact. Katie Copenhaver, a researcher at ORNL, emphasized the ecological benefits, stating, “By utilizing bio-based, large-scale 3D printing, we replaced an assembly made from 31 parts and three materials… read more

A recent advance in bioprinting from the Collins BioMicrosystems Laboratory at the University of Melbourne could significantly reshape tissue engineering. Researchers at the lab, led by biomedical engineer David Collins, have introduced a new 3D bioprinting approach called Dynamic Interface Printing (DIP). Unlike traditional methods that slowly build tissue layer by layer, DIP employs acoustic waves to guide cells into precise configurations, producing complex human tissues in seconds—a process previously hindered by speed and structural limitations. This breakthrough offers the potential for customized, high-fidelity tissue structures with applications across regenerative medicine and disease modeling. The approach can reportedly achieve 3D printing speeds around 350 times faster than those of traditional bioprinters, reducing the chances of cell damage while maintaining high structural accuracy. Most current bioprinters rely on layer-by-layer construction, which often compromises cell viability due to prolonged exposure times and complex post-processing steps. Once printed, tissue structures typically require delicate… read more
Specifications Before we get into the main review, let’s take a look at the specs of the Einstar VEGA. The VEGA features two different types of scanning technologies in one unit. These are VCSEL (Vertical-Cavity Surface-Emitting Laser – for long range scanning in any environment) and MEMS (for short range scanning of highly detailed objects). As the name suggests, it is wireless, meaning it can wirelessly scan, transfer data (to the cloud), and even project onto a second screen (a smart TV is needed), all over your WiFi network. In terms of physical hardware, it is a lightweight unit, weighing in at 535g, with a comfortable and ergonomic shape, made even more ergonomic by its detachable silicone grip. All of the operations are done with its 6.4 Inch 2K AMOLED touchscreen display and its intuitive, clutter-free GUI. Such operations include scanning controls, one-touch editing, and even clipping data (more on… read more
