Recycled Water Bottles Could Help Avoid Military Supply Snags

Soldiers on the battlefield or at remote bases often have to wait weeks for vital replacement parts. Now scientists report they have found a way to fabricate many of these parts within hours under combat conditions using water bottles, cardboard and other recyclable materials found on base as starting materials for 3D printing. They say this ‘game-changing’ advance could improve operational readiness, reduce dependence on outside supply chains, and enhance safety.

“Ideally, soldiers wouldn’t have to wait for the next supply truck to receive vital equipment,” Nicole Zander, Ph.D., says. “Instead, they could basically go into the cafeteria, gather discarded water bottles, milk jugs, cardboard boxes and other recyclable items, then use those materials as feedstocks for 3D printers to make tools, parts and other gadgets.”

Integrated Magneto-Optical Devices for On-Chip Photonic Systems

The magneto-optical (MO) oxide layer consists of (Bi,Y)3Fe5O12 or BiYIG, bismuth garnet. This material was selected because it has a better figure of merit than the CeYIG previously used, especially at lower wavelengths (1310 nm vs. 1550 nm). A top-down deposition process was developed in which BiYIG/YIG stacks are grown on the Si waveguide with YIG on top. The stack is annealed at 800°C/5 min to crystallize both layers, with the YIG templating the BiYIG leading to garnet phases rather than other oxides, and the BiYIG is directly on the Si waveguide. Initial attempts led to a film with Bi oxide phases, because the Bi was in excess and could not escape during the anneal as occurs in Si/YIG/BiYIG stacks. Hence the composition was adjusted to include slightly more Fe, which yielded films with only garnet peaks.

Using Thermoplastics in Aerospace Applications

In August 2017, Qantas Airlines laid down the challenge to both Boeing and Airbus to offer an aircraft that can cross one of aviation's “last frontiers.” That “last frontier” was an aircraft capable of flying an economical passenger load non-stop for over 20 hours. This would allow Qantas to offer direct service from Sydney to London or New York. Weight reduction through the use of thermoplastics and other technologies would be the key to any chance of success in this endeavor.

Hydraulic Testing of Polymer Matrix Composite 102mm Tube Section

The objective of this research was to hydraulically pressurize the internal diameter of one 102mm Polymer Matrix Composite (PMC) over-wrapped cylinder up to 25,000 pounds per square inch (psi) and during pressurization, in real time, collect and store pressure and strain data simultaneously. Strain data must be captured from the inside diameter of the oil filled metallic cylinder and from the outside diameter of the composite over-wrap material.

Streamlining Machinery and Production Lines With HP Multi Jet Fusion 3d Printing

Machinery and production line component production has typically been served with traditional processes such as CNC machining and injection molding. However, as industries strive to find greater efficiencies and add more value for their customers, machinery and production line manufacturers and runners are looking for ways to enhance and optimize how they produce components–in order to offer unique/customized solutions at low cost to their internal or external customers, drive greater production line efficiencies with lightweight, high performance parts, and maximize equipment uptime. 3D printing opens up a world of new opportunities for machinery and production line component production–both for original and spare parts.

Automated Process Prints Aircraft Parts

Copper cables run through the fuselage of aircrafts. They transmit electrical signals for temperature-measuring sensors, LEDs in ceilings, or electronic connections in seats. During their installation, individual cables are combined into harnesses. A new manufacturing process eliminates the classic laying of the cable harnesses, saving space and weight.
