Popis: |
Within this paper, an insert for the integration of female threads into additive manufactured (AM) polymer parts is presented. The fastener consists of three components: a metallic threaded insert, an AM optimized female cutout and an AM polymer clip. By exploiting AM’s geometrical complexity, the design has several advantages compared to conventional solutions including a fast and reversible assembly process without the use of specialized tools. The insert’s pull-out strength was evaluated on a tensile testing machine. The results showed that the fastener can withstand loads of up to 5600 N (for 3/8″-16 UNC thread size). Within a case study, the insert is integrated into a Selective Laser Sintered (SLS) top handle for videography applications. The fasteners were fully functional and endured extensive real-life operation. The results of the experimental tests and case study demonstrate that the novel insert design creates new potentials for AM products, as additional applications for polymer-based AM processes are enabled. Customization and flexibility are established within the hardware part as designers can choose their required insert from ready-to-use building blocks & even change it throughout use as the connection is standardized and reversible. |
