| 中文摘要: |
| 目的 熔融沉积3D打印的聚合物产品由于不同层的熔丝间作用力弱，其层间结合强度显著降低，难以满足工业应用的需求，已成为FDM工艺的瓶颈难题。方法 提出管载胶FDM新方法，以聚合物管材为胶水的载体，通过打印后胶水的化学反应使熔丝间形成化学键粘接，从而显著提升层间结合强度。结果 与传统无胶产品相比，打印产品的拉伸强度提高95%，断裂伸长率提高248%。结论 新的工艺解决了传统FDM 3D打印产品层间结合强度差的难题。 |
| 英文摘要: |
| Limited by the weak interfacial force between fuses in different layers printed by fuse deposition (FDM) 3D printing technology, the interlayer bonding strength of polymer products is seriously degraded and can not satisfy the needs of industrial applications, which has become the bottleneck of FDM. To meet these challenges, an innovative FDM method is proposed to use polymer tubes as the carrier of the glue. The chemical bond is directly formed between the fuses after printingby chemical reactions of the glue, and therefore the interlayer bonding strength is improved. The results show that compared with traditional FDM parts without glue, the tensilestrength and the broken elongation of the obtained product are significantly improved 95% and 248% respectively. This new method solves the bottleneck defect of the traditional FDM. |
