MIT group reveals design for 3D printed fibreglass structures on Mars

Last month, NASA announced the winner of its 3D Printed Habitat Challenge, a competition in which entrants were tasked to develop architectural concepts. These concepts were to implement 3D printing techniques for the construction of habitats on Mars, using materials that could be sourced from the Red Planet itself.

The 3D Printed Habitat Challenge received 165 submissions, with the thirty highest scoring entries being displayed at the New York Maker Faire on September 27th. The overall winner and recipient of the $25,000 grand prize was Team Space Exploration Architecture and Clouds Architecture Office with their Mars Ice House design. The runners up were Team Gamma, who received $15,000, whilst third place was awarded to Team LavaHive.

“The creativity and depth of the designs we’ve seen have impressed us,” said Centennial Challenges Program Manager Monsi Roman. “These teams were not only imaginative and artistic with their entries, but they also really took into account the life-dependent functionality our future space explorers will need in an off-Earth habitat.”

Quantum dots with impermeable shell used as a powerful tool for “nano-engineering”

I never get tired of talking about the many uses for Q-dot technology. One area that has me even more intrigued is how it is used in crystallized formations. I expect to see more and more experimenting on crystalized formations on many fronts including complex circuitry for performance and storage.

And, with synthetic technology today plus 3D printing along with Q-dots we could (as I have eluded to many times over several months) truly begin to see some amazing technology be developed on the wearable tech front.

Wearables could include synthetic circuitry stones in various accessories to not only store information, but also serve as another form of unique id because in synthetic stones we have been able (like in nature) create complex crystalized formations that are each unique/ 1 of a kind like a unique finger print, or iris of an eye. I expect to see some very interesting things coming in this space.

Unique optical features of quantum dots make them an attractive tool for many applications, from cutting-edge displays to medical imaging. Physical, chemical or biological properties of quantum dots must, however, be adapted to the desired needs.

Unfortunately, up to now quantum dots prepared by chemical methods could only be functionalized using copper-based click reactions with retention of their luminescence. This obstacle can be ascribed to the fact that copper ions destroy the ability of quantum dots to emit light. Scientists from the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) in Warsaw and the Faculty of Chemistry of the Warsaw University of Technology (FC WUT) have shown, however, that zinc oxide (ZnO) quantum dots prepared by an original method developed by them, after modification by the click reaction with the participation of copper ions, fully retain their ability to emit light.

“Click reactions catalyzed by copper cations have long attracted the attention of chemists dealing with quantum dots. The experimental results, however, were disappointing: after modification, the luminescence was so poor that they were just not fit for use. We were the first to demonstrate that it is possible to produce quantum dots from organometallic precursors in a way they do not lose their valuable optical properties after being subjected to copper-catalysed click reactions,” says Prof. Janusz Lewinski (IPC PAS, FC WUT).

Five New Ideas to be Explored by NASA Aeronautics Teams

They might not work, but no one will know for sure unless they’re given a chance.

That’s the general idea behind the recent selection of five aviation-related technologies for vigorous study as part of NASA’s ongoing Convergent Aeronautics Solutions project during the next two years of so, which itself is now in its second year.

Researchers will study a new kind of fuel cell, increasing electric motor output with the help of 3D printing, use of Lithium-Air batteries to store energy, new mechanisms for changing the shape of a wing in flight and basing a new antenna design on the use of lightweight aerogel.

Saudis look to Chinese 3D printing company to tackle housing shortage

China’s big win.

Last week a team from Chinese 3D printing construction company WinSun visited Saudi Arabia, meeting with department of housing official and others to discuss the kingdom’s housing shortfall.

According to 3ders.com and others, the Chinese firm’s chairman and vice president met officials from the housing department and investment authority, and were told the Saudi government believes WinSun’s technology could help meet a shortage in available housing. WinSun was invited to open a Saudi factory.

According to an April report from Reuters, the Arab state is looking at a shortfall of 1.5 million housing units over the next five years.

Saudi Arabia plans to 3D print 1.5 million houses with WinSun’s construction 3D printing tech

WOW — now that’s an engineering feat.

While Dubai is keen to become a 3D printing world leader with their Dubai 3D Printing Strategy, they are by no means the only Middle Eastern nation to look into this technology. Last week a delegation of Chinese WinSun officials traveled to Riyadh, the capital of the Kingdom of Saudi Arabia, to discuss construction 3D printing. Among others, the Chinese construction 3D printing pioneers were invited to 3D print up to 1.5 million housing units over the next five years.

WinSun is the company that made construction 3D printing a practical reality. Back in 2014, the Shanghai-based company created headlines all over the internet for building not one, but ten 3D printed houses in less than 24 hours. Since then, Shanghai WinSun Decoration Design Engineering Co., to give its full name, has been building on that initial achievement with one 3D printed concrete creation after another. Back in March, they even unveiled two gorgeous 3D printed Chinese courtyards.
