3D printed metamaterials offer novel optical properties
According to Tufts, the fabrication methods demonstrate how 3D printing can expand the range of geometric designs and material composites that lead to devices with novel optical properties, including a hemispherical device inspired by the compound eye of a moth that absorbs electromagnetic signals from any direction at selected wavelengths. The research is published in Microsystems & Nanoengineering.
In the study, researchers at the Nano Lab at Tufts describe a hybrid fabrication approach using 3D printing, metal coating, and etching to create metamaterials with complex geometries and novel functionalities for wavelengths in the microwave range.

Essentium Announces a Distribution Partnership with Hephzibah to Advance Additive Manufacturing in South Korea

Essentium, Inc., Hephzibah | July 13, 2020

Essentium, Inc., a leading innovator of industrial additive manufacturing (AM) solutions, today announced a distribution partnership with Hephzibah, prominent South Korean 3D printing specialist, to advance additive manufacturing in South Korea. The combination of Hephzibah’s best-in-class service, customer support, and use-case specific expertise, together with the ground-breaking speed and economics of the Essentium High Speed Extrusion (HSETM) 3D Printing Platform will help resolve many of the historic barriers to widespread adoption of industrial-scale AM and to advance additive manufacturing in South Korean market. Manufacturing firms in South Korea recognize that adding 3D printing to their factory floors could save billions in production costs. However, they face significant obstacles to using 3D printing for large-scale production, such as the strength of parts, speed and scale of production, and economics. The Essentium and Hephzibah partnership will deliver AM solutions, based on open ecosystems, that produce parts with the strength, speed, and scale customarily associated with injection-moulding and with vastly improved economics.

Markforged distributes its 3D printers to participants of Project DIAMOnD in Michigan

businesswire | January 06, 2021

Markforged, maker of the world's biggest metal and carbon fiber added substance fabricating stage, the Digital Forge, today declared that it has conveyed its first rush of 3D printers to makers in Michigan as a feature of Project DIAMOnD. An activity made via Automation Alley, Michigan's Industry 4.0 information place, Project DIAMOnD is committed to improving makers' readiness and versatility by causing them scale up their Industry 4.0 movement. In excess of 200 makers have just gotten their printers and are prepared to print individual defensive gear (PPE) when called upon to do as such. Meanwhile, they can likewise utilize the printers for making parts basic to serving and developing their assembling tasks. Undertaking DIAMOnD will empower little and fair sized Michigan producers to print PPE, filling a basic hole in the clinical production network during the proceeded with battle against COVID-19. Every individual printer interfaces with a unified, blockchain-empowered cloud, worked via Automation Alley. The undertaking is ready to turn into the world's biggest crisis reaction network for printing actual items on interest. The undertaking will likewise make inventory network strength and adaptability by introducing an open door for the taking an interest makers to print the parts they may have to keep their lines operational and flexible even with future interruption. Mechanization Alley chose Markforged's 3D printing stage to meet these objectives, alongside Microsoft's Azure cloud innovation. Undertaking DIAMOnD is controlled by an award Automation Alley got from Oakland County and Macomb County, taking into account 300 candidates to get Markforged printers. “There is boundless potential for 3D printing and it’s starting to unfold in Michigan,” said Tom Kelly, Executive Director and CEO of Automation Alley. “With Project DIAMOnD, manufacturers in Michigan are setting the pace for what’s possible. At Automation Alley, we’re eager to direct this initiative and measure the impact it has on the production of healthcare equipment as well as other parts critical to the supply chain across multiple industries.” An assortment of producers in Michigan have applied to partake in Project DIAMOnD, including Tier 1 and Tier 2 providers. The members incorporate HERCO Group, a diecast form and hardware arrangements supplier; Accufacture, a computerization fabricating organization; and Custom Valve Concepts (CVC), a fluid and gas item producer for brands like Nestle, GE, Citgo and PepsiCo. “Additive manufacturing was always on our minds,” said Michael Tor, Associate Engineer at CVC. “After receiving this grant and talking with Markforged, that's when our eyes just started opening up.” The company plans to use the printer to support local frontline workers who need access to PPE, as well as for tooling and fixtures. “I used to look at the local news and see these amazing stories of everyday people, not necessarily engineers, helping out. Now we get to do the same. This project provides an avenue for Custom Valve Concepts to utilize its abilities to help those in our community and has helped kickstart our goal of introducing additive manufacturing into the company,” says Tor. “Project DIAMOnD and the participating manufacturers are bringing the true promise of the Digital Forge to life,” said Michael Kelly, Director of Print System Engineering at Markforged. “Traditionally, governments have maintained special networks dedicated to the distribution of information and goods during emergencies, but this will be the first response network capable of actually manufacturing tangible parts and objects on demand as needs arise. From printing PPE to enabling mass supply chain resiliency, this initiative is showcasing the power of a cloud-connected, digital 3D printing network. Our hope is that, through our contributions, manufacturers can find unique, effective ways to contribute to COVID-19 relief efforts and continue innovating with our printers for years to come.” About Markforged Markforged transforms manufacturing with 3D metal and carbon fiber printers, capable of producing parts tough enough for the factory floor. Engineers, designers, and manufacturing professionals all over the world rely on Markforged metal and composite printers for tooling, fixtures, functional prototyping, and high-value end-use production. Founded in 2013 and based in Watertown, Massachusetts, Markforged has about 300 employees globally, with $137 million in both strategic and venture capital. Markforged was recently recognized by Forbes in the Next Billion-Dollar Startups list and listed as the #2 fastest-growing hardware company in the US in the 2019 Deloitte Fast 500.
