 | 3D printing: Army works on cutting-edge munitions
Army researchers are exploring additive manufacturing technology through a program designed to push the application of 3D printing to new boundaries. The research effort consists of three core teams specializing in energetics, metals, and hybrid additive manufacturing of munitions technologies, along with a design science team that brings together manufacturing and geometric design.

 | Top 5 reasons for solder joint failure
Solder joint reliability is often a pain point in the design of an electronic system. According to Tyler Ferris at ANSYS, a wide variety of factors affect solder joint reliability, and any one of them can drastically reduce joint lifetime. Properly identifying and mitigating potential causes of solder joint failure during the design and manufacturing process can prevent costly and difficult-to-solve problems later in a product lifecycle.

 | Basics of crossed roller bearings
Crossed roller bearings provide more accuracy, rigidity, and weight-bearing capacity for linear motion than other commonly used friction-reducing devices such as ball bearings. And unlike ball bearings, they can support moment loads, radial forces, or tilting loads. This lets one crossed roller bearing replace more than one ball bearing, thus saving the space required by ball bearings, lowering the associated material costs.

 | New fast-cure urethane adhesive speeds assembly
Designed for engineered thermoplastics, e-coated metals, powder painted surfaces, coated metals, composites, and SMC, the LORD 7800 family of fast-cure urethane adhesives will help manufacturers reduce bond and assembly time in the transportation sector. Traditional urethanes cure and build up strength slowly, forcing manufacturers to wait 3 to 12 hours to reach the necessary state to drill, cut, machine, and/or add other components to the assembly. In contrast, the LORD 7800 family cures quickly, reaching those usable strengths often within an hour or less -- with no odor or flammability issues like competing acrylics.

 | DURANEX PBT grade for high-voltage automotive applications
The Polyplastics Group is now offering an improved polybutylene terephthalate (PBT) grade that provides improved tracking resistance for a range of high-voltage automotive components. DURANEX PBT CG7030 is a 30 percent glass-filled material that also delivers strong dimensional stability and highly stable electrical resistance and dielectric breakdown properties. After extensive testing, Polyplastics determined that PBTs are more suitable than PA66 for use in high-voltage applications when it comes to moisture absorption, dimensional change rates, and dielectric breakdown strength in high-heat and humid environments.

Space engineer builds rotary-dial cell phone
Justine Haupt isn't a fan of smartphones, so she designed and built her own weird, wacky, and wonderful alternative -- complete with old-school rotary dial and a curved ePaper display. Now, the design engineer and developer of astronomy instrumentation at Brookhaven National Lab in Long Island, NY, has made available a kit for DIYers. "Builders will still need to find the right rotary dial and order a handful of other bits," Haupt says, "but the 'hard part' (the mainboard and the 3D-printed casing with threaded inserts and buttons) is available for sale." Why create this? "Because in a finicky, annoying, touchscreen world of hyperconnected people using phones they have no control over or understanding of, I wanted something that would be entirely mine, personal, and absolutely tactile," Haupt says, "while also giving me an excuse for not texting."

Apollo 13 views of the Moon in 4K
A new video from NASA Goddard uses data gathered from the Lunar Reconnaissance Orbiter spacecraft to recreate some of the stunning views of the Moon that the Apollo 13 astronauts saw on their perilous journey around the far side in 1970. These visualizations, in 4K resolution, depict many different views of the lunar surface, starting with earthset and sunrise and concluding with the time Apollo 13 reestablished radio contact with Mission Control. Also depicted is the path of the free return trajectory around the Moon, and a continuous view of the Moon throughout that path. All views have been sped up -- they are not shown in real time. Impressive in detail.
