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

Power/Performance Bits: Aug. 14


All-optical logic Researchers from Aalto University developed multifunction all-optical logic gates using a network of nanowires. To build the nanostructure, the team assembled two different semiconductor nanowires, indium phosphide and aluminum gallium arsenide. The nanowires have a unique one-dimensional structure, which allows them to function like nanosized antennas for light. Using ... » read more

Simulation-Driven Product Development In Additive Manufacturing


Additive manufacturing, or 3-D printing, has the potential to radically change the way in which products are conceived and designed. The additive process allows for unprecedented design complexity and design freedoms. Full subassemblies can be produced in one print eliminating costly joining operations. Parts can be customized and produced in small, made- to-order batches. Parts can be produced... » read more
