3D Printing News Briefs, May 20, 2023: 4D Printing, Sustainability, Inclusivity, & More https://ift.tt/Kjf5PHx Starting with space news in today’s 3D Printing News Briefs, a Kansas City startup is building 3D printed re-entry capsules for on-demand cargo return from space. In research, a 3D printed biodegradable seed-robot, which can change shape in response to humidity, was created by researchers in Italy. Materialise completed its first materiality assessment and matrix, and Canadian Filaments and Oco created a new carbon captured filament. Finally, an MIT hardware startup with a focus on inclusivity launched a 3D printed device that allows people to control devices with their tongue, and Earfab’s custom in-ear products are live. Raven Space Systems 3D Printing Re-Entry Capsules for Space CargoKansas City startup Raven Space Systems is one of 14 companies chosen for a technical, business, and mentorship program from Amazon Web Services that will work to transform the future of space. Raven’s automated factory is building 3D printed re-entry capsules for on-demand cargo return from space for less money, at a faster pace, and with adaptability for missions, and the 2023 AWS Space Accelerator is helping it, and the other startups, speed up their growth and advance their solutions. Participants get AWS training, business development and strategy support, mentoring from AWS space domain and technical subject matter experts, and up to $100,000 in AWS Promotional Credit, as well as opportunities to work with AWS customers and AWS Partner Network (APN) Partners. Raven initially focused on material formulations to 3D print aerospace-grade thermoset composite materials at scale, but the co-founders realized that no one was improving the production of re-entry vehicles.
3D Printed Biodegradable Shape-Changing Seed RobotResearchers from the Italian Institute of Technology (IIT) and the University of Trento were inspired by the seeds of the South African geranium, or Pelargonium appendiculatum, in their creation of the I-Seed, a biomimetic robot 3D printed out of biodegradable materials, in the shape of a seed, with the ability to change shape and autonomously explore the soil in response to changes in humidity, which makes it a 4D printed artificial seed prototype. The I-Seed project, funded by the EU and coordinated by IIT, is working to create robots that can be used as sensors to monitor soil quality parameters and air metrics. The group studied the movement and dispersal features of seed-carrying structures in these plants, and found that, under the right environmental conditions, the seeds detach and, “exploiting the hygroscopic properties” of the materials that compose them, change shape and move on their own to penetrate the soil. The seeds exploit dead cellulose-based tissues that have no metabolism and can deform through humidity changes, and after histological analysis of these tissues, the team was able to mimic the seed design through the use of 3D printing and electrospinning.
Materialise Releases Materiality Assessment and MatrixAs a signatory of the UN Global Compact, Materialise has been annually reporting on its sustainability initiatives and progress since 2017, and says that sustainability is a major element of both its mission and shared vision to create a healthier, overall better world. But what’s new with its sustainability strategy is the completion of its first materiality assessment and matrix. In it, Materialise identifies six priority topics for sustainability: carbon footprint; material use efficiency and waste reduction; eco-design and innovation for sustainability; sustainable procurement; diversity and inclusion; and employee engagement and well-being.
In addition to finishing its new materiality assessment and matrix, Materialise is also in the middle of developing a new sustainability dashboard, which should be published soon. Canadian Companies Create Carbon Captured Filament for 3D PrintingCanadian Filaments, which manufactures high-quality 3D printer filaments, and fellow Canada-based company Oco, a climate ambassador that offers businesses the chance to upcycle collected Co2 material, have partnered to create a unique carbon captured filament for 3D printing. The two wanted to provide other AM companies with a more climate-friendly production material to help lower their carbon footprint, and the partners have also begun a take-back and recycle project, in which they will give 3D printing companies the chance to transform printed material back into reusable filament. Their new carbon captured filament has been released under the CUT product name, and is made from Co2 emissions and recycled graphite, processed through Oco’s CUT mechanism. The sustainable, engineering-grade PLA and PETG filaments feature high resilience and durability, and the first company to implement the material is Canadian company CleanO2, which will be 3D printing parts for its CarbinX device that captures carbon and transforms it into materials used to produce other products, like fertilizers, glass, and soap.
Augmental’s Device for Hands-Free Computing Using the TongueHardware startup Augmental, an MIT Media Lab spinoff, is pushing the limits of hands-free computing with its MouthPad^ device, which allows people to interact with and control their devices using only their tongue, which the startup considers “the 11th finger.” There are options for disabled people without the use of their hands to access the digital world, such as eye-tracking technology and lip-controlled joysticks, but the MouthPad^ is a far better option. This smart intraoral interface, customized to each user’s mouth, converts the user’s tongue position and pressure into cursor actions by processing signals through a machine learning algorithm and sending them via Bluetooth to the connected device. Plus, users can seamlessly switch between speech and tongue-driven screen navigation. Intraoral scanning is used to generate a 3D model of the user’s mouth, which helps to create a custom design that’s 3D printed using dental resin. The personalized MouthPad^ encapsulates a processing unit, Bluetooth radio, and flexible circuit board with sensors inside a watertight casing, allowing users to do everything from turning on the lights and sending an email to playing a video game. The goal is to scale up the device so it can be used by the broadest audience—not just disabled people, but also astronauts, surgeons, factory line workers, and more.
Earfab’s Custom In-Ear Products Now Available to OrderDanish company Earfab has officially gone live with its custom in-ear products. The company offers custom products for traveling, sleeping, and hearing protection for activities like hunting, racing, industry work, and concerts. Earfab developed its earfabSCAN app and associated production technology, which are used to digitally create custom in-ear plugs. The process is quick and simple: first, purchase your preferred product, and you will then receive a unique QR code, along with instructions. Next, download the earfabSCAN app (products only work with iPhone x Series, 11 Series or 12 Series), and then scan your ears with your phone and complete your order. In less than ten days, you should receive your custom ear plugs, 3D printed out of biodegradable TPE resin.
