3D Printing For More Circuits


After several years of experimentation, and growing success in volume manufacturing for some use cases, technologies for 3D printing of electronic circuits are becoming more common. Some innovations in processes and materials are moving these technologies closer to mainstream electronics manufacturing. Christopher Tuck, professor of material science at the University of Nottingham, observed ... » read more

Reaching silicon-based NEMS performances with 3D printed nanomechanical resonators


Abstract: "The extreme miniaturization in NEMS resonators offers the possibility to reach an unprecedented resolution in high-performance mass sensing. These very low limits of detection are related to the combination of two factors: a small resonator mass and a high quality factor. The main drawback of NEMS is represented by the highly complex, multi-steps, and expensive fabrication process... » read more

Multicolored Nanocolloidal Hydrogel Inks For Anti-Counterfeiting


Abstract "Nanocolloidal gels are emerging as a promising class of materials with applications as inks in 2D and 3D printing. Polymer nanoparticles (NPs) offer many advantages as potential building blocks of nanocolloidal gels, due to the ability to control NP dimensions, charge, surface chemistry, and functionality; however, their applications as inks in printing are yet to be explored. Here, ... » read more

COVID-19 Tech Bits


Tech companies, consortiums and universities are jumping in to help fight COVID-19, deploying everything from massive computing capabilities to developing new technologies that can protect medical workers and first responders. Nearly all of these have ramped up over the past several weeks, as the tech world begins to take on a global challenge to combat the deadly virus. Compute resources... » read more

Power/Performance Bits: Feb. 10


Balancing battery capacity and stability Researchers at Rice University are working to develop batteries that are better geared toward electric cars and more robust off-grid energy storage by digging into why lithium gets trapped in batteries, thus limiting the number of times it can be charged and discharged at full power. The team found that by not maxing out a battery's storage capacity,... » read more

Manufacturing Bits: Dec. 3


Microscopic movie star Using a 3D printer and a scanning electron microscope (SEM), a group has created a short animated film featuring the world’s smallest 3D figurine. The stop motion film, called Stardust Odyssey, features a 3D human-like figurine with a height of 300 microns, or close to the size of a grain of dust. This beat the previous record for the smallest figure in a film. N... » read more

Manufacturing Bits: Oct. 1


3D balloon printing Using an elastomeric or stretchy balloon, the University of Houston and the University of Colorado have developed a new 3D printing method as a means to develop three-dimensional curvy electronic products. The technology involves the field of 3D printing, sometimes known as additive manufacturing (AM). In 3D printing, the goal is to develop parts layer-by-layer using mat... » read more

3D Metal Printing: Does It Add Up?


Prolific Renaissance artist Michelangelo said, “The sculpture is already complete within the marble block before I start my work. ... I just have to chisel away the superfluous material.” I wonder what the great visionary would think of exchanging his chisel for an additive-manufacturing tool such as today’s 3D printers. 3D printing has been around since the 1980s, when it was first kn... » read more

March’19 Startup Funding: Money Springs Forth


Another month, another couple of billion-dollar rounds. Singapore-based Grab raised nearly $1.5 billion from the SoftBank Vision Fund, bringing its total private funding to more than $4.5 billion and valuing the company at around $14 billion. Grab has acquired Uber’s ride-hailing business in Southeast Asia and now competes chiefly with Go-Jek of Indonesia in Thailand and other emerging mar... » read more

Manufacturing Bits: Feb. 19


Computed Axial Lithography Lawrence Livermore National Laboratory (LLNL) and the University of California at Berkeley have developed a 3D printing method to produce a new class of polymer parts. The technology, called Computed Axial Lithography (CAL), projects photons on a resin in a vial within a 3D printer. In total, researchers have demonstrated the ability to shine 1,440 different proje... » read more
