The effort to secure a stable, domestic source of a critical medical isotope reached an important milestone this month as the U.S. Dept. of Energy's Argonne National Laboratory demonstrated the production, separation and purification of molybdenum-99 (Mo-99) using a process developed in cooperation with SHINE Medical Technologies.
A Massachusetts Institute of Technology team has developed a way of making soft materials, using a 3-D printer, with surface textures that can then be modified at will to be perfectly smooth, or ridged or bumpy, or even to have complex patterns that could be used to guide fluids.
A team of researchers from the Univ. of Twente has found a way to 3D print structures of copper and gold, by stacking microscopically small metal droplets. These droplets are made by melting a thin metal film using a pulsed laser.
Biofuels pioneer Mascoma LLC and the BioEnergy Science Center have developed a revolutionary strain of yeast that could help significantly accelerate the development of biofuels from nonfood plant matter. The approach could provide a pathway to eventual expansion of biofuels production beyond the current output limited to ethanol derived from corn.
A Northwestern Univ. team has confirmed a new way to help the airline industry save dollars while also saving the environment. And the solution comes in three dimensions. By manufacturing aircrafts’ metal parts with 3D printing, airlines could save a significant amount of fuel, materials and other resources.
Researchers have developed a new way of making tough, but soft and wet, biocompatible materials, called “hydrogels,” into complex and intricately patterned shapes. The process might lead to injectable materials for delivering drugs or cells into the body; scaffolds for regenerating load-bearing tissues; or tough but flexible actuators for future robots, the researchers say.
With all of the manufacturing and tooling capabilities, are 3D printers becoming a service-based commodity with all the reticent encumbrances associated with this connotation? Is the technology and its associated materials still advancing at a rapid pace? What are the different capabilities, limitations and applications of the current iterations of 3D printing equipment materials and technologies?
Ever since single-layer graphene burst onto the science scene in 2004, the possibilities for the promising material have seemed nearly endless. With its high electrical conductivity, ability to store energy, and ultra-strong and lightweight structure, graphene has potential for many applications in electronics, energy, the environment and even medicine.
Mollusks got it right. They have soft innards, but their complex exteriors are engineered to protect them in harsh conditions. Engineers at the Indian Institute of Science and Rice Univ. are beginning to understand why. By modeling the average mollusk’s mobile habitat, they are learning how shells stand up to extraordinary pressures at the bottom of the sea.
Researchers from Swinburne Univ. of Technology and the Univ. of Science and Technology of China have developed a low-cost technique that holds promise for a range of scientific and technological applications. They have combined laser printing and capillary force to build complex, self-assembling microstructures using a technique called laser printing capillary-assisted self-assembly (LPCS).
By combining 3-D holographic lithography and 2-D photolithography, researchers from the Univ. of Illinois at Urbana-Champaign have demonstrated a high-performance 3-D microbattery suitable for large-scale on-chip integration with microelectronic devices.
An international team of researchers has created tiny, complex scaffolds that mimic the intricate network of collagen fibers that form the human eardrum. It is hoped the scaffolds can be used to replace eardrums when they become severely damaged, reducing the need for patients to have their own tissue used in reconstruction surgery.
The drop-on-demand inkjet printing is a promising approach allowing patterning of materials with negligible materials waste; hence, significant reduction of raw materials cost can be achieved. Furthermore, inkjet printing can be easily adapted to a roll-to-roll process, which is suitable for large scale production.
In a world where most information is available in an instant, plant managers and engineers are continuously trying to find ways to improve the efficiency of processes along the manufacturing line. Analyzing these processes can be a difficult task. Until recently, days of laboratory work were often required to analyze any given sample segment or process in a manufacturing line.
A new type of graphene aerogel will make for better energy storage, sensors, nanoelectronics, catalysis and separations. Lawrence Livermore National Laboratory researchers have made graphene aerogel microlattices with an engineered architecture via a 3D printing technique known as direct ink writing.
3D printing has been used to make everything from cars to medical implants. Now, Univ. of Washington ecologists are using the technology to make artificial flowers, which they say could revolutionize our understanding of plant-pollinator interactions.
Just a few years ago, many researchers working in alternative manufacturing methods believed the basic layering technologies integral to 3D printing limited the capability of this technique to build quality optical devices and lenses. But, as rapidly evolving as these techniques are, and as broad ranging as the applications it’s infiltrating, this limitation has been surmounted by a number of research groups around the world.
Additive manufacturing has been called a game changer. But new games require new instructions, and the manuals for a growing assortment of methods for building parts and products layer-by-layer, collectively known as "3D printing", still are works in progress. Manufacturing researchers at NIST have scoped out the missing sections in current guidelines for powder bed fusion, the chief method for "printing" metal parts.
New research shows how inkjet-printing technology can be used to mass-produce electronic circuits made of liquid-metal alloys for "soft robots" and flexible electronics. Elastic technologies could make possible a new class of pliable robots and stretchable garments that people might wear to interact with computers or for therapeutic purposes.
Consumers are one step closer to benefiting from packaging that could give simple text warnings when food is contaminated with deadly pathogens like E. coli and Salmonella, and patients could soon receive real-time diagnoses of infections such as C. difficile right in their doctors' offices, saving critical time and trips to the lab.
Imagine you need to have an almost exact copy of an object. Now imagine that you can just pull your smartphone out of your pocket, take a snapshot with its integrated 3-D imager, send it to your 3-D printer and, within minutes, you have reproduced a replica accurate to within microns of the original object. This feat may soon be possible because of a new, tiny high-resolution 3-D imager developed at Caltech.
The 3D printing revolution has changed the way we think about plastics. Everything from children’s toys to office supplies to high-value laboratory equipment can be printed. The potential savings of producing goods at the household- and lab-scale is remarkable, especially when producers use old prints and recycle them.
A 3D printing technology developed by Silicon Valley startup, Carbon3D Inc., enables objects to rise from a liquid media continuously rather than being built layer-by-layer as they have been for the past 25 years, representing a fundamentally new approach to 3D printing. The technology allows ready-to-use products to be made 25 to 100 times faster than other methods.
Engineers at Oregon State Univ. have used additive manufacturing to create an improved type of glucose sensor for patients with Type 1diabetes, part of a system that should work better, cost less and be more comfortable for the patient. A key advance is use of electrohydrodynamic jet, or “e-jet” printing, to make the sensor.
