Materials & Manufacturing

A Tangled Robot

The slimy, segmented, bottom-dwelling California blackworm is about as unappealing as it gets — but get a few dozen or a thousand together, and they form a massive, entangled blob that seems to take on a life of its own.

Dust-Powered 3D Printing

AI SpaceFactory sells 3D printers informed by its work on Marshall Space Flight Center’s Centennial Challenge, which the company won with print material containing crushed basalt similar to ground cover on Mars.

How ISS Will Be Evaluating Photovoltaic Materials

Solar cells account for approximately six percent of the electricity used on Earth; however, in space, they play a significantly larger role, with nearly all satellites relying on advanced solar cells for their power. That’s why Georgia Tech researchers will soon be sending 18 photovoltaic cells to the International Space Station (ISS) for a study of how space conditions affect the devices’ operation over time.

Thin Film Sensor for Ultra High-Temp Measurement

Innovators at NASA Johnson Space Center have developed a thin film sensor that measures temperatures up to 1200 °F, and whose prototype successor may achieve measurements up to ~3000 °F — which was the surface temperature of the Space Shuttle during its atmospheric reentry. Read on to learn more.

Advanced Thermal Inspection with Pulsed Light Emitting Diodes (PLED) Technology

Engineers at NASA Langley Research Center have developed a cutting-edge thermal inspection technology that enhances defect detection on low-emissivity surfaces by eliminating false readings caused by infrared reflections. Read on to learn more.

Twisted Moiré Photonic Crystals

Researchers have developed an on-chip twisted moiré photonic crystal sensor that uses MEMS technology to control the gap and angle between the crystal layers in real time. The sensor can detect and collect detailed polarization and wavelength information simultaneously. Read on to learn more.

3D Printing Self-Heating Microfluidic Devices

MIT researchers have used 3D printing to produce self-heating microfluidic devices, demonstrating a technique which could someday be used to rapidly create cheap, yet accurate, tools to detect a host of diseases. Read on to learn more.

Diversifying the Supply Chain for Producing Large-Scale Metal Parts

Researchers at the Department of Energy’s Oak Ridge National Laboratory are using advanced manufacturing techniques to revitalize the domestic production of very large metal parts that weigh at least 10,000 pounds each and are necessary for a variety of industries, including clean energy. Read on to learn more.

A One-Piece Liquid Rocket Thrust Chamber Assembly

NASA researchers are eliminating complex joints by manufacturing a 1-piece TCA utilizing 3D printing and large-scale additive manufacturing technologies to directly deposit the nozzle onto the combustion chamber. And, by replacing a traditional solid metal jacket with a composite overwrap for support, the overall weight is reduced by over 40 percent. Read on to learn more.

Flexible Silicon Photovoltaics: A Breakthrough in Space-Grade Solar Power

In-space manufacturing is expected to become a core part of future space economy by using assets in orbits or beyond Earth orbit for use in space. Tech Briefs interviewed space-focused solar energy startup Solestial’s CTO Stanislau Herasimenka about the key technology developments leading to this increased momentum for space-based manufacturing and the role solar power will play in it. Read on for the full interview with Herasimenka, edited for length and clarity.

Positioning Wafers with Micrometer Precision for PECVD Coating

For loading and unloading workpiece carriers containing wafers of different sizes in an automated process prior to PECVD coating, acp systems has developed a robotic solution aided by image processing for a leading manufacturer of space solar technology. Read on to learn more.

Sensitive Yet Tough Photonic Devices Are Now a Reality

Engineers at the University of California San Diego have achieved a long-sought milestone in photonics: creating tiny optical devices that are both highly sensitive and durable — two qualities that have long been considered fundamentally incompatible. Read on to learn more.

Friction That Cools

How can a horde of active robots be automatically brought to a standstill? By arresting their dynamics in a self-sustained way. This phenomenon was discovered by physicists at Heinrich Heine University Düsseldorf (HHU)...

AI Shapes Autonomous Underwater “Gliders”

Marine scientists have long marveled at how animals like fish and seals swim so efficiently despite having different shapes. Their bodies are optimized for efficient, hydrodynamic aquatic...

5Ws of the Ping Pong Bot

MIT engineers have developed a ping-pong-playing robot that quickly estimates the speed and trajectory of an incoming ball and precisely hits it with precision.

Piasecki's KARGO UAV Program: Enabling Uncrewed Logistics

John Piasecki, CEO of Piasecki Aircraft Corporation, is the guest on this episode of the Aerospace & Defense Technology podcast to discuss the future of the KARGO UAV program.

Using AI to Perfect the 3D Printing of Metals

Professor Ashif Iquebal together with Professor Aviral Shrivastava and their team at Arizona State University are developing methods for improving the quality of highly critical metal parts manufactured using 3D printing.
