We’re beginning with sustainability information in at this time’s 3D Printing Information Briefs, as EOS has strengthened its dedication on local weather duty, 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 Web-Zero Greenhouse Gasoline Emissions by 2045 with Science-Primarily based Targets
In celebration of World Surroundings Day 2025 earlier this month, EOS—already a high provider of Accountable Manufacturing options—introduced that the globally acknowledged company motion group Science Primarily based Targets initiative (SBTi) has permitted its science-based targets (SBT) to obtain net-zero greenhouse gasoline emissions by 2045. With this milestone, the corporate joins quite a lot of 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 Web-Zero Normal of SBTi, which works to assist monetary establishments and corporations all over the world do what they will to fight the local weather disaster, and align with the Paris Settlement’s targets to restrict international 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 would additionally take measures to develop extra sustainable supplies, electrify the corporate automobile fleet, transition to renewable electrical energy throughout websites, and improve effectivity of its processes and methods.
“We’re proud to take this vital 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
Based on Italian firm Zestep, greater than 70% on common of the cellulose acetate used to supply 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 answer 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 had been “conscious of the vital influence that this venture might have for the sustainable recycling of a fabric that’s as distinctive as it’s complicated to course of.” After verifying that the waste will 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 capable of extrude high-quality 3D printing filament out of the waste materials, and after a 12 months of examine and experiments, their patent-pending ReAcetate, produced and distributed by Techinit, is on the market 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 presently activating college collaborations to proceed R&D work on doable materials functions.
“The Zestep venture was awarded on the ADI Design Museum because the successful U35 venture of Genoa DesignWeek 2024. Awarded with the non permanent exhibition within the Compasso d’Oro museum, through which we confirmed the recycling course of: from the waste taken from the manufacturing facility, to the thing printed with the identical materials,” the corporate wrote.
ORNL Presents Quicker Automotive Tooling with 3D Printing Steel Molds

Analysis carried out on the Manufacturing Demonstration Facility (MDF) at Oak Ridge Nationwide Laboratory (ORNL) reveals that large-scale additive manufacturing might actually pace up auto manufacturing within the U.S. In a venture 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 sooner, less expensive, and versatile strategy to fabricating giant composite elements for mass-produced automobiles. Steel molds are usually made by eradicating as much as 98% of the unique materials from giant, solid metal blocks, which is a prolonged and wasteful course of. AM builds up materials in layers, slightly than chopping it out, and can even 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 gasoline metallic arc welding (GMAW) course of at Lincoln Electrical Additive Options to print two near-net-shape dies from stainless-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 expertise may help reindustrialize the U.S. and enhance its competitiveness by creating smarter, sooner 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 difficult designs, so it may possibly take months to supply alternative elements, and weavers should borrow elements 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 material is exported to over 60 nations, and utilized by the likes of Dior and Ralph Lauren, so it’s vital 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 elements. A part of the Excessive Worth Manufacturing (HVM) Catapult, NMIS is operated by the College of Strathclyde, and engineers at its Digital Manufacturing unit in Renfrewshire examined a spread of supplies to supply essentially the most sturdy, high-quality loom elements. One key loom meeting was made up of seven elements, 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 will be produced domestically in simply two hours.
“We take satisfaction in our craftsmanship and custom, however we additionally know that innovation is important for preserving our trade robust for the generations to come back,” stated Kelly McDonald, Operations Supervisor at The Harris Tweed Authority. “Working with NMIS is a major step ahead in future-proofing the looms essential to the manufacturing of Harris Tweed®. With the power to interchange elements rapidly, simply, and affordably, our weavers can concentrate on what they do greatest with out worrying about delays. This not solely safeguards the way forward for our material but additionally helps the livelihoods of the island neighborhood who dedicate their expertise to preserving the craft.”
The preliminary part of this venture is full, however work continues, as the last word purpose is to create simply fitted, adaptable elements that may keep the integrity of the standard craft of weaving.
