NASA’s aeronautical researchers are using 3D printing to generate new data to deal with the aviation safety problem of icing. High-fidelity data of ice shapes generated on aircraft wings are documented through laser 3D scanning. Complex ice shapes are also 3D printed to better understand ice formation and its effects on an airplane.
That data, which will be publicly available in 2020, is the result of a cooperative five-year research program that involved NASA, the Federal Aviation Administration (FAA), The French Aerospace Lab (ONERA), and several U.S. universities.

Title Lunar 3D printing competition winner
Released 04/09/2019 9:27 am
Copyright J. Santiago
Description
Judith de Santiago, winner of the under 18 category of ESA’s lunar 3D printing competition, with the printed version of her design: a dodecahedron (or 12-sided) plant pot.
While studying lunar base concepts ESA ran a competition, asking: what would you 3D print on the Moon, to make it feel like home?
Judith, a student from Madrid, Spain, proposed a pot for plants that would be cherished on a Moon base, incorporating symbols of Earth: “The blue curves of the bottom represent the waves of the sea, and the badge with a small plant located at the centre, inspired by Disney’s movie WALL·E, represents the Earth in general.”

Aerosint, an award-winning Belgian SLS 3D printer manufacturer, Vectoflow, a German fluid-dynamic metrology device developer, and Fraunhofer IGCV have received a €750,000 grant from the Eurostars program to develop multi-functional airflow sensors.
Flow probes within the sensors are used for the development of jet engines and gas turbines. In an effort to make them more accurate and cost-effective, the partners, which comprise an international project consortium, will utilize laser powder bed fusion (LPBF) technology to 3D print to create advanced flow systems.

Lego Wars!

https://3dprintingindustry.com/news/3d-printing-community-hit-by-lego-takedown-notices-162451/

Last week 3D Printing Industry learned that the Lego Group is targetting the 3D printing maker community with a series of takedown notices.
A 2010 ECJ ruling found that although the classic LEGO brick was not protectable by trademark, protection would be granted to the Danish company’s minifigures or minifigs as they are widely known. The current notices seen by 3D Printing Industry refer specifically to the “famous red-square LEGO logo and the Minifigure figurine” and ask recipients to “Please act expeditiously to remove the listings.”

Scientists from the University of Sheffield have integrated antibacterial properties into polymer powders to create 3D printed parts capable of fighting infectious diseases.
In a study published in Scientific Reports, silver-based additives were combined with PA 12 and then processed using an EOS Formiga P100 SLS system to additively manufacture antimicrobial components that were not toxic to human cells.

New research from the Tokyo University of Science has revealed what happens to water molecules on the surface of graphene. The study, led by Professor Takahiro Yamamoto, combined statistical data analysis tools with molecular dynamics simulations to explore the change in the structure of water when in contact with the carbon-based material, suggesting there is much to learn about the interaction between water and 3D printed materials.

New Jersey-based Rutgers University engineers have developed their version of bio-ink, which is made of living cells and used to 3D print scaffolds for human tissue growth.
The team originally set out to build a nerve graft for peripheral nerves but changed the focus of their work during the course of the study, eventually leading them to develop the new bio-ink at the end of the four years.

US-based Relativity Space has secured its new headquarters in the hub of the aerospace community in Long Beach, California. The facility will be home to both the company’s business operations and its fully automated, metal additive manufacturing production line.
“Long Beach has an extensive history as a leader in aerospace and aviation, and now we are at the forefront of the space economy,” said California Senator Lena Gonzalez. “We are excited to welcome Relativity to our ever-growing community of innovative tech companies.”
By using machine learning, software, robotics, and additive manufacturing, Relativity Space plans to produce Terran 1, the world’s first fully 3D printed rocket.

Printing a telescope for space
This weirdly organic item is the answer to an engineering question: how to take the maximum benefit from 3D printing to produce a highly demanding item for a space mission? An ESA-led team began with a Dutch-designed space telescope which identifies ozone and other trace gases in Earth’s atmosphere, then comprehensively redesigned it for manufacture in this innovative way.

https://3dprintingindustry.com/news...to-save-lives-of-coronavirus-patients-169136/

With Italy now at the center of active Coronavirus cases, the country is in lockdown to combat the rapid spread of COVID-19. The large number of cases means that, inevitably, a huge strain has been placed on Italy’s healthcare system, and its supply chain.
Reports provide details of a hospital in Brescia with 250 Coronavirus patients in intensive care connected to breathing machines. Soon however, the hospital had run out of respiratory valves which are needed to connect the patients to the breathing machines. The original supplier of the valves was unable to supply the new ones in the time required.
In response, Cristian Fracassi, CEO of Isinnova, a Brescia-based engineering firm, used 3D printing to meet the hospital’s demands and, in the process, save some of the patients’ lives. Working with local machining manufacturer Lonati, they were able to produce 100 respirator valves in 24 hours.
