We’re beginning with sustainability information in at present’s 3D Printing Information Briefs, as EOS has strengthened its dedication on local weather accountability, and Zestep is making 3D printing filament out of eyewear manufacturing waste. Transferring on, ORNL is conducting analysis into 3D printed metallic molds for automotive functions. Lastly, historic textile model Harris Tweed® is utilizing 3D printing to breathe new life into its weaving machines.
EOS Pledges Internet-Zero Greenhouse Gasoline Emissions by 2045 with Science-Based mostly Targets
In celebration of World Surroundings Day 2025 earlier this month, EOS—already a prime provider of Accountable Manufacturing options—introduced that the globally acknowledged company motion group Science Based mostly Targets initiative (SBTi) has authorised its science-based targets (SBT) to obtain net-zero greenhouse fuel emissions by 2045. With this milestone, the corporate joins quite a few others all over the world responding to the decision for local weather motion, whereas additionally aligning with buyer expectations. Its targets are grounded within the Internet-Zero Customary of SBTi, which works to assist monetary establishments and firms all over the world do what they will to fight the local weather disaster, and align with the Paris Settlement’s targets to restrict world warming to 1.5°C. EOS’s SBTs embody 42% absolute discount in Scope 1 and a couple of CO2e emissions by 2030 and 90% absolute discount in Scope 3 CO2e emissions by 2045. It’ll additionally take measures to develop extra sustainable supplies, electrify the corporate automobile fleet, transition to renewable electrical energy throughout websites, and enhance effectivity of its processes and programs.
“We’re proud to take this essential step towards a 1.5-degree future, reinforcing our dedication to significant local weather motion and to supporting our prospects on their sustainability journeys. Our validated science-based targets replicate EOS’ dedication to Accountable Manufacturing and our position in serving to drive sustainability progress inside the additive manufacturing trade,” stated Marie Langer, the CEO of EOS.
Zestep Utilizing Eyewear Manufacturing Waste to Make 3D Printing Filament
In accordance with Italian firm Zestep, greater than 70% on common of the cellulose acetate used to provide one set of eyeglass frames is wasted. That’s why this group of younger creatives and technicians is on a mission to scale back the environmental influence of the Italian eyewear trade. Their resolution is recycling this waste materials into 3D printing filament. To get the uncooked materials, the group reached out to optics and eyewear factories, in addition to cellulose acetate producers, who they are saying have been “conscious of the essential influence that this challenge may have for the sustainable recycling of a cloth that’s as distinctive as it’s complicated to course of.” After verifying that the waste could be equipped with out worry of contamination from different supplies, Zestep carried out a sequence of exams to find out an “optimum level for processing the fabric.” The group says it’s in a position to extrude high-quality 3D printing filament out of the waste materials, and after a yr of examine and experiments, their patent-pending ReAcetate, produced and distributed by Techinit, is obtainable for buy in each 250g and 700g spools. Zestep says the filament is simple to print, with glorious adhesion and resistance to breakage. The corporate is at the moment activating college collaborations to proceed R&D work on doable materials functions.
“The Zestep challenge was awarded on the ADI Design Museum because the profitable U35 challenge of Genoa DesignWeek 2024. Awarded with the non permanent exhibition within the Compasso d’Oro museum, wherein we confirmed the recycling course of: from the waste taken from the manufacturing facility, to the article printed with the identical materials,” the corporate wrote.
ORNL Presents Quicker Automotive Tooling with 3D Printing Metallic Molds

Analysis carried out on the Manufacturing Demonstration Facility (MDF) at Oak Ridge Nationwide Laboratory (ORNL) exhibits that large-scale additive manufacturing may actually velocity up auto manufacturing within the U.S. In a challenge funded by the DOE’s Superior Supplies and Manufacturing Applied sciences Workplace (AMMTO), the group discovered that, when in comparison with conventional tooling, 3D printed metallic molds are a quicker, more cost effective, and versatile method to fabricating massive composite elements for mass-produced autos. Metallic molds are sometimes made by eradicating as much as 98% of the unique materials from massive, solid metal blocks, which is a prolonged and wasteful course of. AM builds up materials in layers, relatively than reducing it out, and may allow extra complicated inside geometries. ORNL researchers partnered with Collaborative Composites Options (CCS), operator of IACMI–The Composites Institute, to check out the idea, and 3D printed a big battery enclosure mildew with intricate inside options. They used a fuel metallic arc welding (GMAW) course of at Lincoln Electrical Additive Options to print two near-net-shape dies from chrome steel ER410 wire, utilizing a specialised toolpath technique to take care of power whereas lowering weight. Evaluation confirmed that the lightweighted mildew met the structural efficiency necessities.
“This sort of know-how may help reindustrialize the U.S. and increase its competitiveness by creating smarter, quicker methods to construct important instruments. It brings us nearer to an automatic, clever manufacturing course of,” stated lead researcher Andrzej Nycz with ORNL’s Manufacturing Robotics and Controls group.
Harris Tweed® Utilizing 3D Printing to Future-Proof Weaving Machines
Legally, Harris Tweed® textiles can solely be handwoven within the properties of weavers in Scotland’s Outer Hebrides. Sadly, the looms have sophisticated designs, so it might probably take months to supply substitute elements, and weavers should borrow components from one another or modify looms on their very own; weaver John Bennie as soon as repurposed a Ford Ka flywheel to enhance his loom. The enduring cloth is exported to over 60 international locations, and utilized by the likes of Dior and Ralph Lauren, so it’s essential to maintain issues up and operating. To future-proof this historic craft, The Harris Tweed Loom Spares Co. is partnering with the Nationwide Manufacturing Institute Scotland (NMIS) to create a extra accessible loom meeting design that includes 3D printed components. A part of the Excessive Worth Manufacturing (HVM) Catapult, NMIS is operated by the College of Strathclyde, and engineers at its Digital Manufacturing facility in Renfrewshire examined a variety of supplies to provide essentially the most sturdy, high-quality loom elements. One key loom meeting was made up of seven components, however utilizing a robust composite materials, has been redesigned so it may be made with simply three. The 3D printed half prices 99% much less, and could be produced domestically in simply two hours.
“We take pleasure in our craftsmanship and custom, however we additionally know that innovation is significant for maintaining our trade robust for the generations to come back,” stated Kelly McDonald, Operations Supervisor at The Harris Tweed Authority. “Working with NMIS is a big step ahead in future-proofing the looms crucial to the manufacturing of Harris Tweed®. With the flexibility to exchange components rapidly, simply, and affordably, our weavers can deal with what they do finest with out worrying about delays. This not solely safeguards the way forward for our cloth but in addition helps the livelihoods of the island neighborhood who dedicate their abilities to preserving the craft.”
The preliminary section of this challenge is full, however work continues, as the final word objective is to create simply fitted, adaptable components that may keep the integrity of the normal craft of weaving.
