Convert rotary to linear motion
Lead screws are a common power transmission technology used to convert rotary motion into linear motion. igus® dryspin plastic lead screws and nuts are geometrically and tribologically optimized for lower wear and higher efficiency than other lead screw nut technologies, and are a self-lubricating alternative to ball screws in a wide range of applications.

NASA 3D prints first full-scale copper rocket engine part
When you think of copper, the penny in your pocket may come to mind, but NASA engineers are trying to save taxpayers millions of pennies by 3D printing the first full-scale, copper rocket engine part.

Image - Precision dispensing for micro-electronics engineering
Precision dispensing for micro-electronics engineering
The spread of miniaturization in automation has led to an ever-increasing demand for optimum dispensing of the tiniest volumes. Whether in electronics or micro-mechanical engineering: solder pastes, adhesives, lubricants, and sealing compounds must be applied precisely where needed, in exactly the right dosage, and without spillage or dripping. Micro dc motors provide a compact and highly controlled precision solution.

LED Pulser invention delivers laser-like performance at fraction of the cost
When Sandia National Laboratories electronics engineer Chris Carlen got enthusiastic about flashlights containing high-power LEDs, he didn’t expect his hobby to lead to the creation of a new, high-speed LED driver that delivers lighting performance that exceeds that of conventional sources at a fraction of the cost. In some cases, the LED Pulser can displace more expensive lasers.

Wings:
New polymer creates safer jet fuels

Before embarking on a transcontinental journey, jet airplanes fill up with tens of thousands of gallons of fuel. In the event of a crash, such large quantities of fuel increase the severity of an explosion upon impact. Researchers at Caltech and JPL have discovered a polymeric fuel additive that can reduce the intensity of postimpact explosions that occur during accidents and terrorist acts. Furthermore, preliminary results show that the additive can provide this benefit without adversely affecting fuel performance.

Mike Likes: In-mold electronic inks
DuPont Microcircuit Materials has launched a suite of in-mold electronic inks designed to help streamline electronic devices by reducing the need for rigid circuit boards. By printing circuits directly onto plastic substrates, touch controls (such as electronic buttons, switches, and slides) are readily integrated in applications such as home appliances and automobiles. The inks offer important design, manufacturing, weight, and cost advantages and mark the further expansion of DuPont advanced materials enabling printed electronics. The new DuPont ME series in-mold electronic inks are designed to withstand demanding manufacturing processes such as thermoforming and injection molding. They also simplify the assembly process because there is only a single connection point and no wires behind the console. This can reduce the weight of a console by more than 70 percent.

Creators of machine that recycles plastics into 3D-printer filament get design boost from Autodesk

Toronto-based ReDeTec envisions a world where makers can create and develop in a sustainable fashion. The company’s first product, the ProtoCycler, allows users to recycle waste plastic from 3D printing into valuable new 3D-printer filament. To help design the ProtoCycler, the ReDeTec team turned to the Autodesk Cleantech Partner Program and software including Autodesk Fusion 360, Autodesk Inventor, and Autodesk PLM 360.

Image - Heating tech: Maximize diesel engine performance
Heating tech: Maximize diesel engine performance
The new ECO-HEAT exhaust gas heating system from Watlow functions as an internal load bank in medium stationary and mobile diesel generator applications. Incorporating ECO-HEAT into a diesel generator’s aftertreatment system helps eliminate problems encountered under low generator load conditions, such as increased engine back pressure due to excessive soot loading, poor NOx conversion, and fouled EGR valves. Unlike external load banks that require a completely separate footprint and waste their heat to the surrounding environment, ECO-HEAT is designed to be installed in the exhaust pipe and provides heat directly where it is needed: within the aftertreatment system. Using electricity from the generator, it increases exhaust gas temperatures by both increasing load on the diesel engine and heating the exhaust directly.

Fasteners: Spring-loaded captive panel screw
New PEM ReelFast surface-mount spring-loaded captive panel screws (Type SMTPFLSM) from PennEngineering install precisely and permanently where designed on printed circuit boards to provide secure attachment and allow for subsequent access whenever necessary. These all-metal captive screw assemblies mount in one piece on boards using the pick-and-place method and will install in the same manner and at the same time as other surface-mount components prior to the automated reflow solder process. The captive screw technology eliminates issues and risks associated with the handling, installing, and potential loosening of standard screws and can be easily actuated with the combination Torx/slot drive.

Robotics: Adaptive gripper with advanced control
Robotiq recently released the 2-Finger 140 Adaptive Robot Gripper, a large-stroke electric gripper with advanced control features. It is able to detect that a part has been picked, as well as pick soft, fragile, or deformable parts without crushing them while maintaining a safe grip when the robot is moving. This unit is ideal for high-mix pick-and-place operations for various industries such as electronics, consumer goods, and logistics.

NASA tests acrylics for Orion spacecraft windows
When astronauts travel to an asteroid and toward Mars in NASA’s Orion spacecraft, they’ll get a tremendous view of their deep-space destinations and of Earth through the spacecraft’s windows. NASA engineers are making sure those windows will be more structurally sound, lighter, and cheaper than on previous spacecraft.

What does Alka Seltzer do in space?
Astronauts on the International Space Station dissolved an effervescent tablet in a floating ball of water and captured images using a camera capable of recording four times the resolution of normal high-definition cameras. The higher resolution images and higher frame rate videos give researchers a valuable new tool aboard the space station. This footage is one of the first of its kind. The cameras are being evaluated for capturing science data and vehicle operations by engineers at NASA's Marshall Space Flight Center in Huntsville, AL.
