Relativity Space and 6K partner to create circular economy for AM powders (3DPMN)

Relativity Space has announced a strategic alliance with 6K, a developer of microwave plasma technology for powder production, to 3D print rocket components made from sustainable materials. The partnership will establish a closed loop supply chain through which scrap materials produced by Relativity will be transformed into premium AM powders by 6K and redeployed to Relativity…

Biological Polymers as a Catalyst for the Circular Economy (Part 2)

As many of you liked the article on biological polymers that can lead to circular manufacturing models, I will dive deeper into this topic, explaining how a transition to biological polymers could be achieved. So far we have learned that the most abundant organic biopolymers like cellulose and chitin can be used to produce very strong…

Graphene: The Superpower Material

Nature’s simple palette results in products far more advanced than those produced by human industrial science. Seashells that are twice as tough as science’s best ceramics. Spiders can spin silk that is stronger than steel yet light enough to float on the wind. Nature suggests that the potential for inventive uses of easily recycled materials is…

3D Printing with Bioplastics: Engineering Biodegradable PHA Blends (3dPrint.com)

Jackie Anderson offers a review regarding one of the most critical 3D printing topics today: materials. As innovation continues to grow, so do the options regarding software, hardware, and different types of plastics (along with many other alternatives today). In ‘Engineering Biodegradable PHA Blends,’ Anderson explores issues with plastic waste, and the need to use more…

Sulzer: PLA advances are changing the plastics industry (bioplasticsmagazine.com)

The recent development of new polymerization methods that allow the economical production of poly lactic acid (PLA) with a higher molecular weight have effectively removed many of the limiting factors on its use, opening-up a greatly expanded application base for the plant-based bioplastic. This is happening just at a time when pressures on extended supply lines…

Biological Polymers as a Catalyst for the Circular Economy (Part 1)

In an previous article we have seen that nature uses simple basic components but fits them so skillfully together, that quality materials result. Its above all design that makes intelligent materials out of basic ones. We have described how we can use 3d printing and generative design technology with simple materials to create similar complex structures…

Researchers design bionic 3D printed corals that could help energy production and coral reefs (ForgePress)

Although corals may look like plants, they are actually animal structures that host dense populations of algae on their surfaces. Corals provide a host for tiny photosynthetic algae. This intricate symbiotic relationship between coral and algae is responsible for maintaining the high diversity of coral reef ecosystems. Whilst coral reefs cover only one per cent of…
