Researchers determine the effects of powder recycling on stainless steel 316L

Researchers from the I-Form Advanced Manufacturing Research Centre in Dublin have published a study investigating the effects of metal powder reuse on the porosity of 3D printed parts. The team employed X-ray tomography, AFM (atomic force microscopy) roughness measurements, and nanoindentation measurements with the aim of determining the optimum number of reuse cycles for stainless

3D printing low-cost robotic mechanical prostheses for amputees

Researchers in Brazil have published a study aiming to improve the characteristics and accessibility of robotic mechanical prosthesis with 3D printing.  Mechanized prostheses have the potential to provide a viable low-cost alternative for simulating the functions lost by disabled people. However, it’s high value means these devices have low purchasing power, rendering them inaccessible.  In

The state of the Kenzan method of scaffold-free 3D bioprinting in 2020

A recent progress report published in the journal Advanced Healthcare Materials details the results of various experiments that have utilized the Kenzan method of 3D bioprinting to produce cell constructs for transplantation. The paper is intended to give readers an overview of the state of the art technology in 2020. Since the turn of the millennium, research

Largest and hottest shield volcano on Earth

In a recently published study, researchers from the University of Hawai’i at Mānoa School of Ocean and Earth Science and Technology revealed the largest and hottest shield volcano on Earth. A team of volcanologists and ocean explorers used several lines of evidence to determine Pūhāhonu, a volcano within the Papahānaumokuākea Marine National Monument now holds

NIOSH publishes health & safety advice for 3D printing with filaments and metal powders

The National Institute for Occupational Safety and Health (NIOSH) has published two new posters regarding 3D printing material safety for the workplace and at home. The first details steps that can be taken to ensure safe FDM operation with filaments and the second is concerned with metal powder handling. The information compiled in the posters is

A century of misunderstanding of a key tool in the economics of natural resources

In an article written in 1931, the American economist and mathematician Harold Hotelling published a model to describe the evolution of the prices of non-renewable resources. Following the 1973 oil crisis, the model aroused fresh interest: the growth theorist Robert Solow named the initial equation in this article ‘the Hotelling rule’, establishing it as a

New evidence shows giant meteorite impacts formed parts of the Moon’s crust

New research published today in the journal Nature Astronomy reveals a type of destructive event most often associated with disaster movies and dinosaur extinction may have also contributed to the formation of the Moon’s surface. A group of international scientists led by the Royal Ontario Museum has discovered that the formation of ancient rocks on

The role of European policy for improving power plant fuel efficiency

A new study published in the Journal of the Association of Environmental and Resource Economists investigates the impact of the European Union Emissions Trading Scheme (EU ETS), the largest international cap-and-trade system for greenhouse gas emissions in the world, on power plant fuel efficiency. In “The European Union Emissions Trading Scheme and Fuel Efficiency of

Why smartphones are digital truth serum

Researchers from University of Pennsylvania published a new paper in the Journal of Marketing that explains that the device people use to communicate can affect the extent to which they are willing to disclose intimate or personal information about themselves. The study forthcoming in the Journal of Marketing is titled “Full Disclosure: How Smartphones Enhance

Stabilizing brain-computer interfaces

Researchers from Carnegie Mellon University (CMU) and the University of Pittsburgh (Pitt) have published research in Nature Biomedical Engineering that will drastically improve brain-computer interfaces and their ability to remain stabilized during use, greatly reducing or potentially eliminating the need to recalibrate these devices during or between experiments. Brain-computer interfaces (BCI) are devices that enable
