Closed loop innovation for fused filament fabrication (CLIFFF)

熔融长丝制造闭环创新（CLIFFF）项目将使工业和学术3D打印服务机构能够将废弃的3D打印件重新加工成高价值的新3D打印长丝，为增材制造（AM）领域创建一个完整的循环商业模式。增材制造和3D打印是一个快速增长的工业领域，然而，围绕这个快速增长的行业存在环境问题。与其他塑料产品不同，目前还没有建立3D打印聚合物部件的报废（EoL）处理系统，因此绝大多数丢弃的打印件最终都被填埋。因此，CLIFFF项目将在行业仍在成熟的时候采取积极主动的方法。主要目标是使用新颖的基于近红外的方法为EoL和失败的3D打印创建材料识别系统，创建新的逆向物流业务模式，并开发实验室规模的处理设施。该工厂将粉碎和挤压失败的打印回高质量的3D打印机长丝，将在一系列商用3D打印机上进行全面测试。最终用户的参与和反馈将有助于确保该方法的长期可持续性。与传统的大规模集中回收系统不同，拟议的系统将在区域内部署，以减少运输成本和相关的环境影响。项目团队由三个组织组成。拥有30年历史的打印公司GoPrint3D， HSSMI是一家制造RTO和In-Cycle材料回收技术中小企业，将运营12个月。

The Closed Loop Innovation in Fused Filament Fabrication (CLIFFF) project will enable industry and academic 3D print service bureaus to reprocess discarded 3D prints back into high value new 3D printing filaments creating a fully circular business model for the Additive manufacturing (AM) sector.AM and 3D printing is a rapidly growing industrial sector, however, there are environmental concerns around this fast-growing sector. Unlike other plastic products, there is currently no established End-Of-Life (EoL) processing system for 3D printed polymer parts, so the vast majority of discarded prints ultimately end up in landfill.The CLIFFF project will therefore take a proactive approach whilst the industry is still maturing. Main objectives are to create a material identification system for EoL and failed 3D prints using a novel NIR based approach, create new reverse logistics business models and develop a lab-scale processing facility. The facility will shred and extrude the failed prints back into high quality 3D printer filament that will be comprehensively tested on a range of commercial 3D printers. End-user engagement and feedback will help ensure the long term sustainability of the approach. As opposed to a traditional large scale centralized recycling systems, the proposed system would be deployed regionally to reduce transportation costs and associated environmental impacts.The project team consists three organisations. GoPrint3D, a 30-year-old printing company, HSSMI a manufacturing RTO and In-Cycle a materials recycling technology SME and will run for 12 months.
