A New Path for Lamination Adhesives: Leaping Time Barriers and Erasing Steps

Automotive manufacturers, particularly in North America, primarily use two-component waterborne, reactive hot-melt, and solvent-borne adhesives for laminating thermoplastic olefin, polyvinyl chloride and leather skins to polyethylene and polypropylene foams — for applications like interior door panels, consoles and instrument panels.

What's New on TechBriefs.com: 3D Printing's Next Frontier

In 1983, when Chuck Hull was spending nights and weekends building the first 3D printer, he couldn’t have imagined that someone would eventually use the apparatus to build a toaster from ashes.

Strain-Detecting Composite Materials

These materials can be used in aerospace vehicles and aircraft, or in any application where monitoring total overload or localized strain is critical.

NASA Langley Research Center has developed a metallic material that can be embedded into structural alloys to enhance nondestructive evaluation (NDE) of a structure. Current NDE tools, such as eddy current probes and others, can have some difficulties detecting small flaws in certain materials and structures. Also, using them can be costly, time-consuming, and labor-intensive, often resulting in significant downtime in the case of examination of machinery and vehicles. This innovation is to embed particles that react to strain with easily detected acoustic emissions and change in magnetic properties.

Researchers Sculpt Optical Micro-Structures

Materials scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute of Biologically Inspired Engineering used a new framework to grow sophisticated optical micro-components, including trumpet-shaped assemblages that operate as waveguides.

How 3D Printing Began, Layer by Layer

In 1983, Chuck Hull worked for a small California-based company that used ultraviolet light to turn liquid polymers into hardened, or cured, coatings. Inside the firm’s lab on his nights and weekends, Hull found a way to make UV-curable materials the basis for his Stereolithography Apparatus, patented the following year.

Tech Briefs spoke with Hull about the future of his invention, the 3D printer.

Top 3 Myths of Injection Molding

Rapid injection molding has changed the way product developers and design engineers use manufacturing. No longer is injection molding limited to traditional methods that are time consuming, expensive, and only ideal for larger part quantities. Over the last decade, manufacturing has evolved to allow low volumes of molded parts within days, and do so at a fraction of the traditional tooling cost.

The 3D Printing Landscape: Then and Now

Frequently used as a design validation and prototyping tool in its early days, the 3D printer now supports a much wider range of applications, from shape-conforming electronics to the creation of printed living tissue. Tech Briefs spoke with industry expert Terry Wohlers about 3D printing's emerging possibilities.

3D Printing Applications for Medical Education and Training

3D printed multi-material models can replicate the complexity and wide range of patient pathology, making them superior tools for medical education. But how do 3D printed models compare to traditional training methods? In multiple peer reviews, users agree they can be an invaluable asset to training and better prepare practitioners for the clinical realm. The studies evaluated:

Will fog displays improve design processes?

Today’s lead INSIDER story addressed a new kind of 3D visualization: a shape-shifting fog display. Researcher and co-creator Diego Martinez said the technology enables new ways to collaborate, but the display will ultimately need to be “brought into the light, one step at a time, over years.” What do you think? Will fog displays improve design processes?

Product of the Month: May 2017

Spectrum Instrumentation Corp. (Hackensack, NJ) introduced the DN6.44x, a range of 12 high-speed, 14-, and 16-bit LXI-based digitizers with up to 24 fully synchronized channels. The 16 bit ADC models offers sampling rates of either 130 MS/s or 250 MS/s, while the 14 bit units feature sampling rates of 500 MS/s. The units are suitable for applications where arrays of receivers, sensors, detectors, rectifiers, antennas and other electronic devices are to be used and tested. Each channel is also equipped with its own front-end amplifier that features six input ranges (from ±200 mV up to ±10 V full scale), switchable input impedance (50 Ω and 1 MΩ) and programmable positive input offset for unipolar signals. Analog bandwidth is as high as 250 MHz (for 500 MS/s models), enabling the units to capture electronic signals in the DC to 200 MHz frequency range. The instruments are equipped with a large on-board acquisition memory of 512 MSamples per channel.
