A life cycle analysis (LCA) carried out by 3D printer manufacturerEOS和Fraunhofer EMIhas revealed significant sustainability benefits of 3D printing eyewear frames over those that are traditionally manufactured.
EOS客户制造的3D打印眼镜框架你mawowere found to have a 58 percent lower carbon footprint than conventional glasses. The LCA took into account each stage of the production process from material sourcing through to packaging and shipping, and assessed the environmental impacts of both the conventional and 3D printed glasses across 18 different categories.
EOS可持续发展主管BjörnHannappel说：“我们正在塑造负责任的制造业的未来。”“我们的目标和目的是将开创性的数字创新结合在工业3D印刷和可持续实践中。我们刚刚进行的LCA支持这种方法，它证明EOS目前正在提供市场上最具创新性的方法来生产大型定制眼镜。
“We are proud to partner with YOU MAWO in their passionate journey to offer each person individually optimized and sustainable eyewear.”
EOS’ green credentials
In line with its mission statement“shaping the future of manufacturing”EOS一直在寻求不断改善自己的系统和流程，以降低能耗并提高运营效率。公司试图实现这一目标的一种方法是开发更多基于生物的和生物降解的3D打印材料来实现其零废物视觉。
之上being appointed CEO of EOSin 2019, Marie Langer pledged that the company would do more with the “positive environmental and social benefits” of 3D printing, in a bid to foster more responsible manufacturing. To this end, the firm is working with its customers to develop more customized, industrial 3D printing applications that offer less material consumption, limit over-production, and reduce waste.
4月，该公司宣布已经selected to represent the 3D printing sectoras part of the50个可持续性和气候领导者initiative. The initiative is a climate action-focused project from the international business community that provides companies with a platform upon which they can work to combat climate change.
你mawo’s 3D printed glasses
Founded in 2016, YOU MAWO leverages EOS’ 3D printing technology to produce bespoke eyewear frames for its customer base, which includes some 800 opticians located in 15 countries around the world. The firm deploys specialized 3D scanning software, parametric 3D processes, and EOS’ 3D printing technology to produce frames that are entirely personalized to the wearer.
Together with EOS and Fraunhofer EMI, YOU MAWO has carried out a cradle-to-grave LCA for its 3D printed frames – up until the point of use – in order to compare the environmental impacts of additively and conventionally manufactured eyewear. The study spanned the entire life cycle of the frames, from material sourcing and production to packaging and shipping.
LCA比较了两种眼镜产品在总共18个影响类别中的环境影响，该类别评估了气候变化，人类毒性，臭氧耗竭和水的耗竭等因素。根据合作伙伴的说法，您的Mawo的3D打印眼镜框架的表现要比每个类别中的传统框架“明显好”。
In particular, YOU MAWO’s 3D printed frames were found to have a 58 percent lower carbon footprint than traditional frames, and also created 80 percent less waste than conventionally produced Acetate frames while avoiding lengthy post-processing.
“Together with EOS, we are creating the future of custom-made, 3D printed eyewear,” said Sebastian Zenetti, Managing Director and Head of Sales at YOU MAWO. “The EOS technology convinced us as it meets our high quality, low scrap rate criteria. It supports our strive for sustainable production and products.
“As the technology enables the design and manufacturing of highly individualized eyewear, it also helps to avoid overproduction, minimize supply chains, and enable on-demand production.”
Improving sustainability further
您的Mawo今年早些时候在德国建立了其生产和组装业务，其所有生产设备，基本材料和消耗品都在其从该国采购的饰面和染色工艺中使用。该公司的地点也都由可再生能源提供动力，但是该研究表明，该公司可以进一步提高其流程的可持续性。
您可以做到这一点的一种方法是进一步降低其生产过程中的粉末刷新速率，并开发具有较低环境足迹的生物基粉末。LCA建议该公司还可以采用较便宜的包装。
From an EOS perspective, the LCA provided greater transparency regarding the carbon footprint of this particular 3D printed eyewear application. The data generated during the study will help the firm to better understand the key impact factors for achieving more sustainable 3D printing-based production in regards to CO2 emissions, in order to optimize its technology, processes and materials.
Fraunhofer EMI研究助理塞巴斯蒂安·基尔切特（Sebastian Kilchert）说：“我们很高兴在为该项目进行LCA方面增加了专业知识，因此可以实现一项基于科学的研究。”“将研究集中在特定应用上至关重要 - 在这种情况下是眼镜。结果以积极的方式令人惊讶。
“We expected a similar environmental impact compared to the investigated conventional manufacturing scenario but learned that additive manufacturing performed much better and had roughly only one third of the environmental impact.”
新兴的3D印刷眼镜市场
Various companies have been leveraging 3D printing to produce personalized glasses for some time, due to the technology’s inherent flexibility and customization opportunities.
Notable examples include阿迪达斯“ 3D CMPT”运动太阳镜, which are designed to be both lightweight and shock-absorbing, and French eyewear brand莫雷尔的novelty velvet-textured glasses, which the firm is reportedly成千上万的制造业.
Elsewhere,Materialise通过收购软件开发人员，已经进入了光学3D打印Ditto, which enabled the development of anonline eyewear try-on service.
3D printed ‘smart’ glasses have also garnered recent attention, after prescription lens 3D printing specialistLuxexcelteamed up withOptiswiss带来3D printed smart lensesto glasses manufacturers en-masse. The firm had previously made advances in its AR-related offering through a partnership with波动which saw it begin3D printing AR prescription smart glassesin February.
