Biodiversity is on the verge of being devastated due to the inclination towards deforestation these days. The adverse climatic conditions that our Earth is facing nowadays are also the result of this pressing concern. However, to mitigate this climatic distress caused by deforestation, a team of researchers at the MIT Institute has come up with a novel technique to artificially grow wood in a controlled environment in the lab, which can then be used for making furniture and other wooden houses, which are now being made from cutting trees, thereby posing a threat to our natural habitat. Apart from the amazing growth, we can also print “3D custom-designed wooden structures” out of the replicas, which can considerably reduce wood waste as well.

Prior to discussing the mechanism of wood production, an interesting thing to note is that we can easily change the shape and structure of these artificially produced woods according to our requirements. The researchers have demonstrated the whole process through an experiment in which a flowering plant known as “Common zinnia (Zinnia Elegans)” would be taken and the cells are then extracted from its leaves which can then be conserved in a liquid mixture for several days. After it becomes nutritionally embellished, a gel-based material would be utilized to further refine the mixture.

However, these cells would then give birth to new plant cells which will then be treated accordingly as per the lab conditions. Moreover, we can also reform the physical and mechanical properties of the cells by increasing or decreasing the hormonal concentrations as per the needs.

A new bioprinter is proven to work in space. Researchers demonstrated they could 3D print human tissue cells on the International Space Station.

Nina Notman learns how 4D printing is opening the door to unique smart materials whose applications may only be limited by our imaginations.

Smart materials are already part of our daily lives. From novelty mugs with thermochromic pigments that change colour when holding a hot drink, to photochromic prescription glasses’ lenses that darken when the sun is out, to hydrogels that expand to soak up liquid in disposable nappies and period products. But these are only the tip of the iceberg in terms of what smart materials – that can sense information about the environment around them and then act accordingly – are predicted to achieve in the future.

According to a recent Royal Society report, smart materials on the way include window glass that changes porosity in response to humidity, clothing that adapts to environmental conditions and self-healing concretes. ‘Animate materials could eventually have a transformative effect on all spheres of life,’ the report authors wrote.

“Spacecraft antenna designs are challenging due to their conflicting requirements for high gain, wide bandwidth, and low weight,” Mitsubishi announced. “High gain and wide bandwidth necessarily require a large aperture, but economical orbital deployment conventionally dictates that designs be lightweight and small enough to fit or fold inside a launch vehicle or satellite deployment mechanism.”

Mitsubishi also claimed that, with its new technology, ‘additive-manufacturing in space has now become possible.’ However, it’s worth noting that the International Space Station already features a 3D printer launched to the orbital station back in 2014. The European Space Agency also announced last year it would experiment with 3D printing in space using scrap metals from the Moon.

Still, the company’s new method has the potential to reduce the cost of satellite launches significantly, and it could pave the way for the construction of other vital parts for future space missions.

Objects can now be 3D-printed in opaque resin.

China is building a new hydroelectric dam using AI and 3D printing. No human workers will be involved, according to a new study.

A 3D printing technique can incorporate invisible tags into objects. The process could be used to keep the convenience of QR codes without making them visible, as well as to turn simple objects into videogame controllers.

Admatec has steadily been increasing its 3D printing capabilities, taking its slurry-based digital light processing (DLP) process further. First it expanded from resins loaded with ceramic particles to those loaded with metal particles. It then increased the build volume of its Admaflex300 3D printer. Now, the company has introduced a new integrated debinding and sintering furnace with a larger work volume.

The majority of ceramic 3D printing processes rely on the use of a photopolymer slurry loaded with ceramic particles. Once printed, these green parts first go through a debinding process, in which the photopolymer material is removed, followed by sintering, causing the part to become fully dense.
