New 3D printing method is sustainable and reversible (The Engineer)

Engineers at the University of California San Diego have developed a new 3D printing method that uses a polymer ink and salt water solution to create solid structures. Detailed in Nature Communications, the work is claimed to have the potential to make materials manufacturing more sustainable and environmentally friendly. The process uses PNIPAM (poly(N-isopropylacrylamide)) ink. When this…

‘We don’t need more concrete’: A new village in Tanzania will use a 3D printer and soil to build its community (CNN)

Building with 3D printers has matured rapidly in recent years, as advances in technology and material science allow for grander and more ambitious designs. The potential uses are also increasingly varied, from affordable housing to a planned NASA base on the Moon. Most 3D-printed structures are built using concrete or other pourable, cementitious substances that are cheap,…

From Users to Owners: DePINs and the Sharing Economy for Infrastructure

In the traditional model of infrastructure, roads, power grids, and internet connectivity are passively consumed. We rely on centralized authorities to build and maintain these systems, often with limited transparency or user participation. But what if there was a way to break free from this model and become active contributors? Imagine a world where you contribute…

This 3D printed prefab takes recycling to the max (TheSpaces)

When it comes to property, $20,000 doesn’t usually get you much. That’s not the case with Azure Printed Homes, which offers not only cost-effective but also sustainable housing as the world’s first robotically 3D-printed homes made using recycled plastic. The Los Angeles-based start-up was founded by British engineer Ross Maguire and real-estate developer Gene Eidelman in 2019 to offer a sustainable,…

Focus| Driving circular plastics economy in Additive Manufacturing (3dadept.com)

We have grown up in an environment where plastic, once used, is considered waste. This burden has prevented generations of consumers and industries from capturing the economic benefits of plastic. With Additive Manufacturing and circular economy at the top of Europe’s agenda, waste that was considered a burden before has now turned into gold. The only…

Recyclable Bio-Sourced Resin Offers a Sustainable Future for 3D Printing (TechnologyNetworks)

A new type of recyclable resin, made from biosourced materials, has been designed for use in 3D printing applications. In a study, published today in Nature, researchers from the University of Birmingham showed that high-resolution, 3D printed structures can be manufactured from an entirely bio-sourced feedstock. Once they have reached the end of their useful life, the products…
