German polymer manufacturerCovestrohas announced the addition of the eco-friendly new Arnite AM2001 GF polyethylene terephthalate (PET) to its FGF 3D printing material portfolio.
Made from recycled plastic waste, the glass-fiber filled polymer possesses the mechanical properties needed for scalable construction applications, while leaving a significantly smaller carbon footprint than conventional raw materials.
Covestro’s feedstock, which is its first to be developed by theAM division it acquired from DSM, is essentially designed to help clients make their supply chains more circular, without compromising on their end-performance.
“随着宠物包装的占塑料全部废物的50％以上，由于原料提供了可用于维珍原材料的广泛可用替代品，从而延长了其寿命，而无需妥协绩效或总拥有成本。”添加剂制造（以前是DSM）负责人雨果·达·席尔雷电竞充值瓦（Hugo da Silva）。
“The introduction of this high-performing material for 3D pellet printing is an important step in creating circular supply chains.”
Covestro的3D打印投资组合
Covestro在2020年创造了107亿欧元的收入，是世界上最大的工业聚合物生产商之一。该公司为从汽车到家具和电子产品等领域的客户开发涂料，粘合剂，泡沫和复合材料，并且最近特别着眼于进一步的循环经济原则。
Just last year, the firm set-up its ‘Circular Economy Program,’ through which it’s aiming to halve its greenhouse gas emissions, by producing its polymers out of alternatives to fossil fuels. Additionally, as part of the five-year initiative, Covestro has committed 80% of its R&D spending to working towards the UN’s Sustainable Development Goals (SDGs).
The firm’s eco-friendly ethos has also extended to its recent product launches, and atFormnext Connect, it released a new line ofsustainably-produced Addigy and cardyonfilaments. Made partially of either recycled plastic or CO2Covestro的最新聚碳酸酯（PC）和热塑性聚氨酯（TPU）旨在减少浪费，同时促进3D打印的效率优势。
Since then, the company has completed its acquisition ofDSM的树脂和功能材料细分市场，并宣布其意图“将SLA的好处带到DLP。”就目前的前DSM部门而言，它具有丰富的大幅面3D打印体验，推出了new bio-based EcoPaXX pellet2020年11月的FGF生产。
利用其颗粒投资组合，该组织也与Juggerbot 3D到探索FGF 3D打印的潜力, and制作了一个行人桥in Rotterdam from recyclable source materials. As a result, Covestro’s new feedstock launch doesn’t reflect a change of direction for either firm, but does at least show that they share joint sustainability objectives.
Sustainable FGF 3D printing
Covestro称为“ RPET”，Arnite AM 2001 GF是一种颗粒材料，由重新利用的后消费后塑料废物组成，由玻璃纤维增强。新的原料已专门针对大型零件的FGF 3D打印进行了优化，并具有广泛的处理窗口，非常适合在施工应用中使用。
In addition to being suitable for the production of architecture like bridges, tunnels, cladding, walls or even outdoor furniture, Covestro says that rPET users also stand to benefit from FGF’s intrinsic flexibility. Using the technology, it’s possible to manufacture sizable structures more quickly than conventional processes allow, while creating less waste by only using the amount of material that is required.
Given that Arnite AM 2001 (G) is the first polymer to come from the company’s new material subsidiary, it also says that the feedstock “perfectly fits its vision for a circular economy,” and demonstrates a synergy between the two organizations’ sustainability goals, as they work towards “adding value to AM and industrial production” moving forwards.
“我们对此项研究倍感兴奋的介绍中国保监会ular material designed by our new colleagues,” concluded Patrick Rosso, Head of Additive Manufacturing (Covestro). “This material is the best proof point we could want to underpin the two teams’ joint ambition, to bring the market a stronger materials partner, that can help accelerate industrial additive manufacturing.”
基于缩放颗粒的打印
Covestro对DSM的3D打印材料部门的收购可能为其提供了快速推出新的FGF颗粒的手段，但它远非该市场上唯一的公司。在过去的六个月中，3D打印机OEMTitan Roboticshas worked to qualify贾比尔’s纤维增强尼龙颗粒for its proprietary extrusion-based Atlas systems.
同样，Titan Robotics也与石油化学公司合作Braskem, to develop and launch a line ofpolypropylene (PP) FGF 3D printing resins。During processing, the material reportedly displays low warpage and strong inter-layer adhesion, potentially making it ideal for use within the automotive, chemical or gas sectors.
在其他地方，大型3D打印机OEM喜欢Massive Dimensionhave continued to develop new FGF approaches, and the firm launched an upgraded直接打印粒子挤出机2020年11月。据说与原始挤出机相比五倍，其设计为安装在CNC机器和机器人臂上。
