The capability to produce suture material using three-dimensional (3D) printing technology may have applications in remote health facilities where rapid restocking of supplies is not an option. This is a feasibility study evaluating the usability of 3D-printed sutures in the repair of a laceration wound when compared with standard suture material. The 3D-printed suture material was manufactured using a fused deposition modelling 3D printer and nylon 3D printing filament. Study participants were tasked with performing laceration repairs on the pigs' feet, first with 3-0 WeGo nylon suture material, followed by the 3D-printed nylon suture material. Twenty-six participants were enrolled in the study. Survey data demonstrated statistical significance with how well the 3D suture material performed with knot tying, 8.9 versus 7.5 (p = 0.0018). Statistical significance was observed in the 3D-printed suture's ultimate tensile strength when compared to the 3-0 Novafil suture (274.8 vs. 199.8 MPa, p = 0.0096). The 3D-printed suture also demonstrated statistical significance in ultimate extension when compared to commercial 3-0 WeGo nylon suture (49% vs. 37%, p = 0.0215). This study was successful in using 3D printing technology to manufacture suture material and provided insight into its usability when compared to standard suture material.
利用三维（3D）打印技术生产缝合材料的能力，可能在偏远的医疗设施中具有应用价值，因为在这些地方无法实现快速补充物资。这是一项可行性研究，旨在评估3D打印缝线在修复撕裂伤时与标准缝合材料相比的可用性。3D打印缝合材料是使用熔融沉积建模3D打印机和尼龙3D打印丝制造的。研究参与者的任务是对猪蹄进行撕裂伤修复，首先使用3-0 WeGo尼龙缝合材料，然后使用3D打印的尼龙缝合材料。26名参与者参与了该研究。调查数据显示，3D缝合材料在打结方面的表现具有统计学意义，评分为8.9分，而3-0 WeGo尼龙缝合材料为7.5分（p = 0.0018）。与3-0 Novafil缝合线相比，3D打印缝合线的极限抗拉强度具有统计学意义（274.8 vs. 199.8 MPa，p = 0.0096）。与商用3-0 WeGo尼龙缝合线相比，3D打印缝合线在极限伸长率方面也具有统计学意义（49% vs. 37%，p = 0.0215）。这项研究成功地利用3D打印技术制造了缝合材料，并提供了与标准缝合材料相比其可用性的相关见解。
