Storing renewable energy as methane

The cost of renewable energy has been steadily decreasing, but the big question has always been how to store it for future use.

Biosensor may provide better cancer diagnosis

Lawrence Livermore National Laboratory researchers have developed a new biological sensor that could help clinicians better diagnose cancer and epilepsy.

3D printing method creates objects in one piece

It looks like something you might find aboard the Starship Enterprise. A projector beams a three-dimensional video into a container of photosensitive resin. The video plays while the container rotates for a few minutes — then the fluid drains, leaving behind a complete, fully formed 3D object.

3D-printed supercapacitor electrode breaks records

Advances in supercapacitor technology could lead to wider use of fast-charging energy storage devices and novel designs for electronic gadgets.

Neural networks detect defects in metal 3D printing

For years, Lawrence Livermore National Laboratory engineers and scientists have used an array of sensors and imaging techniques to analyze the physics and processes behind metal 3D printing in an ongoing effort to build higher quality metal parts the first time, every time.

Novel process to 3D print graphene

Researchers have developed a novel way to 3D print complex objects of one of the highest-performing materials used in the battery and aerospace industries.

TRUMPF GmbH + Co. KG

TRUMPF are a manufacturer of machine tools and industrial laser systems; some of their products are fiber lasers. IDTechEx had discussions with TRUMPF at SPIE Photonics West 2018 (USA) and LASYS 2018 (Germany).

Scientists successfully print glass optics

For the first time, researchers have successfully 3D-printed optical-quality glasses, on par with commercial glass products currently available on the market.

Ideal material for smart photovoltaic windows

Imagine that when a window is darkened, it simultaneously produces electricity. Such a material - a photovoltaic glass that is also reversibly thermochromic - is a green technology researchers have long worked toward, and now, scientists have demonstrated a way to make it work.

Lab unlocks secrets of nanoscale 3D printing

Researchers have discovered novel ways to extend the capabilities of two-photon lithography, a high-resolution 3D printing technique capable of producing nanoscale features smaller than one-hundredth the width of a human hair.

Volumetric 3D printing builds on need for speed

While additive manufacturing is enabling engineers and scientists to build parts in configurations and designs never before possible, the impact of the technology has been limited by layer-based printing methods, which can take up to hours or days to build three-dimensional parts, depending on their complexity.

Breakthrough in 3D printed marine grade stainless steel

Researchers have achieved a breakthrough in 3D printing one of the most common forms of marine grade stainless steel - a low-carbon type called 316L - that promises an unparalleled combination of high-strength and high-ductility properties for the ubiquitous alloy.

NIF technology could revolutionize 3D printing

A technology originally developed to smooth out and pattern high-powered laser beams for the National Ignition Facility can be used to 3D print metal objects faster than ever before.

Lab breakthrough in 3D printing of glass

Scientists and academic collaborators have demonstrated the synthesis of transparent glass through 3D printing, a development that could ultimately lead to altering the design and structure of lasers and other devices that incorporate optics.

Reinventing metal 3D printing with new direct writing process

Metal 3D printing has enormous potential to revolutionize modern manufacturing. However, the most popular metal printing processes, which use lasers to fuse together fine metal powder, have their limitations.

3D printing with high-performance carbon fiber

Researchers have become the first to 3D print aerospace-grade carbon fiber composites, opening the door to greater control and optimization of the lightweight, yet stronger than steel material.

3D printed metamaterial shrinks when heated

Researchers have developed 3D printed materials with a unique property - instead of expanding when heated, they shrink.
