With more and more green initiatives popping up around the world, the market for materials making environmentally-sustainable claims seems to be exploding. This week alone, there’s been a whole slew of developments regarding biopolymer-based 3D printing filaments. Over in Canada, materials firms BOSK Bioproducts and Filaments.ca have launched the country’s first entirely bio-based, compostable line of 3D printing filaments. Named ‘Made with REGEN’, the PHA-based biopolymers contain no fossil fuel oils or chemical additives. Elsewhere, in London, the Otrivin Air Lab exhibition is showcasing how photobioreactors can be used to turn CO2 waste into 3D printing materials. Created by Claudia Pasquero and Marco Poletto of the ecoLogicStudio, the exhibition features a set of 12 photobioreactors capable of photosynthesis, which use CO2 to produce biomass that can be harvested to make 3D printable biopolymer filaments. In the research sphere, scientists at EPFL have developed their own biopolymer using non-edible plant material,… read more

A group of Italian researchers has developed a 3D printed artificial skin that could be used to improve the tactile sensing capabilities of robots. Researchers from Scuola Superiore Sant’Anna, Ca’ Foscari University of Venice, and the Sapienza University of Rome created the 3D printed skin which successfully mimicked the function of Ruffini receptors, a type of cell located on subcutaneous human skin tissue that detect stretching, vibrations, warmth, and pressure. Once attached to a robot and combined with a deep learning algorithm based on a multi-layered convolutional neural network (CNN), the skin can estimate the force and point at which the robot comes into contact with an object, potentially enabling safer human-robot cooperation in the future.

Magnum (the ice cream people) have commissioned Dutch designer Iris van Herpen to design and craft a dress inspired by their own vegan ice cream. That means using sustainable and non-animal based materials. The dress has been designed, and it was all made possible by use of 3D printed bioplastics made from algae and cocoa bean husks. You can see the dress, which was shown at this year’s Paris Fashion Week in the image below. Cocoa bean husks (Image credit: Magnum) The dress, according to press materials, features plantlike body embellishments which are copper-coated, draped and entwined with upcycled and organza, while the cocoa husk elements were 3D printed. What is interesting about this story is the use of cocoa husks in the plastic, and how algae is used rather than a traditional consumer plastic in the blend. Cocoa seeds grow in husks, and these husks form a huge amount… read more
The London Borough of Hackney recently awarded £600,000 in grants via its Hackney Central Impact and Ideas Grant Fund, supporting local businesses pushing the circular economy. The program involved a total of 23 green enterprises, including Batch.Works, an East London design and manufacturing studio using 3D printing to upcycle plastic waste into useful products. Riding off the back of the initiative, the Hackney Council is now actively encouraging other local businesses to partake in discussions regarding the circular economy, all in a bid to cut waste, reuse materials, and slash emissions. Guy Nicholson, Deputy Mayor for Delivery, Inclusive Economy, and Regeneration, said, “It is all too easy to jettison some of our ambitions to reduce emissions, support the creation of a circular economy and play our collective part in transforming Hackney’s local economy and placing it at the forefront of the net zero carbon economy of tomorrow. Despite the challenges… read more
Intercourse Outlets Adult Entertainment Shops Cirilla’s Retailer Locator This is due to the extremely sensible feeling that this model name is able to provide throughout stimulation. One sort of intercourse toy that has grown in recognition is the rabbit vibrator. What makes this vibrator so well-liked is because of its capacity to stimulate both the vagina and clitoris best male sleeve, thus permitting a girl to attain each a g-spot and clitoral orgasm. This is as a result of increasingly more individuals, both ladies and men, are opening up to the concept of exploring their sexual wants. “Cheap” tends to get lumped with “poor high quality.” And chastity thong can you use vaseline for masturbating0, vibrators under $50 is most likely not rechargeable. In layman’s terms, we can simply say that there are four unique textures, all different shapes, which make for distinct pressures and sensations on your penis. We… read more
