A Versatile Three-Dimensional Printing Approach

This technology can generate integrated circuits, electrical connectors, supercapacitors, and flow cell batteries.NASA has developed a versatile method and associated apparatus for constructing and using a conductive filament in various applications of 3D printing. It uses an attractive polymer formulation, which exhibits low melting temperature even when combined with conductive material, as the printing filament material. It may be used with a commercial 3D printer to generate custom 3D conductive geometries, such as integrated circuitries, electrical connectors, supercapacitors, and flow cell batteries. This invention can be used to create conductive, piezoelectric, or multifunctional materials using three-dimensional printing, with relatively low melt or glass transition temperatures. This invention should be useful wherever such materials are needed, with modest fabrication costs.

Puncture-Healing Thermoplastic Resin Carbon-Fiber Reinforced Composites

This technology self-repairs following low- to mid-velocity impacts. A through-transmission C-scan of the healable composite panel shows the material post-impact (top) and post-healing cycle (bottom). NASA’s Langley Research Center has developed carbon fiber reinforced composites with self-healing properties. The initiation and propagation of damage to carbon composites, such as in aircraft structural components, results in component failure. Typical structural repairs result in damaging practices, where material is ground away and holes are drilled to secure patches, which can act as new sites for damage. This technology exhibits effective self-repair that heals quickly following low- to mid-velocity impacts, while retaining structural integrity.

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.
