Improved Impact Toughness and Heat Treatment for Cast Aluminum

NASA’s Marshall Space Flight Center researchers have developed a new, stronger aluminum alloy, ideal for cast aluminum products that have powder or paint-baked thermal coatings. With advanced mechanical properties, the NASA-427 alloy shows greater tensile strength and increased ductility, providing substantial improvement in impact toughness. In addition, this alloy improves the thermal coating process by decreasing the time required for heat treatment. With improvements in both strength and processing time, use of the alloy provides reduced materials and production costs, lower product weight, and better product performance. The superior properties of NASA-427 can benefit many industries, including automotive, where it is particularly well suited for use in aluminum wheels.

Dynamically Variable Spot Size Laser System

Applications include aerospace engine repair, medical hardware manufacturing, plastic mold and die restoration, and jewelry manufacturing and repair.NASA’s Marshall Space Flight Center developed the handheld laser torch, designed for welding and brazing metals, to repair hard-to-reach Space Shuttle engine nozzles. It incorporates various manual controls and changing lenses to allow the operator to adjust the laser’s power output in real time. The controls and lenses are designed to increase precision, portability, and maneuverability as compared to existing automated lasers and traditional welding techniques such as tungsten inert gas (TIG), metal inert gas (MIG), or gas-tungsten arc welding (GTAW) systems. Proximity sensors with automated shut-off switches also ensure a high level of safety for the user.

Optimize Production for Agile Manufacturing

This e-book will show how 3D printing can make dramatic improvements in both time and cost efficiency when compared with traditional production methods associated with these applications. Real world examples are also provided to show that these aren’t just hypothetical scenarios. The companies highlighted in this e-book found a way to transform traditional manufacturing applications using FDM technology and bring their operation to a new level.

3D Printed Jigs and Fixtures Save Time and Reduce Cost

There is an often-overlooked additive manufacturing (AM) application with potentially huge financial returns: jig and fixture making. Replacing conventionally manufactured jigs and fixtures with additively manufactured ones will reduce the fabrication expense, while reducing labor and speeding delivery. But that financial advantage is tiny when compared to the profit gains that result from production-floor reductions in labor and time to market. Learn how four owners of Stratasys Fortus 3D printers justified new AM systems based solely on jigs and fixtures.

4D Printing: New dimension for additive manufacturing

A team of Lawrence Livermore National Laboratory researchers have demonstrated the 3D printing of shape-shifting structures that can fold or unfold to reshape themselves when exposed to heat or electricity. The micro-architected structures are fabricated from a conductive, environmentally responsive polymer ink developed at the lab.

Achieving Reliable Inline Measurements in Production Environments

One of the most important changes in metrology in the past few decades has been the development of portable measuring devices. This has brought inspection right to the production line, as close to the part as possible. The change—sparked by the development of portable measuring arms and the emergence of laser trackers—has turned conventional industry inspection methods completely upside down.
