摘　　要：针对熔融丝材制造(FFF)型3D打印机的典型耗材(PLA/ABS)废料的回收效率不高,不适用集中式回收系统的现状,开发一款更适合3D打印丝材废料回收的分布式回收系统,包含实现丝材回收再生的完整流程。该系统集成了6个主要组成部分:破碎装置、混料装置、熔融挤出装置、冷却装置、尺寸自动控制装置和绕线装置,符合模块化设计方案。通过有限元分析软件ANSYS Workbench对系统中关键零件螺杆进行静力学分析,计算螺杆在工况载荷条件下的受力与变形,结果表明,螺杆的强度和刚度均满足设计要求。In view of the current situation that the recycling efficiency of typical consumable(PLA/ABS)scrapsfrom fused filament fabrication(FFF)3D Printers is not high and the centralized recycling system is not applicable,a distributed recycling system applicable to 3D printing filament scraps is developed,which contains a complete process to achieve filament recycling and regeneration.The system integrates six main parts,crushing device,mixing device,melt extrusion device,cooling device,automatic size control device and winding device,which conforms to the modular design scheme.The finite element analysis software ANSYS Workbench is used to carry out static analysis on the screw,a key component of the system,to calculate the force and deformation of the screw under working load conditions,and the results show that the strength and stiffness of the screw meet the design requirements.
