由于创客文化的发展，使用多台熔融沉积建模(FDM)-3D打印机的创客空间在世界各地蔓延。然而，众所周知，3D打印过程会导致超细颗粒和细颗粒的释放，这可能会对居住者的健康产生不利影响。因此，本实验以放置于实际创客空间的FDM-3D打印机为研究对象，通过操作FDM-3D打印机的数量、通风情况和测量位置三种场景，比较超细颗粒和细颗粒的浓度。此外，采用呼吸沉积模型预测超细颗粒和细颗粒在肺泡区的沉积剂量，分析其对人体的潜在健康风险。因此，基于场景的比较显示，如果3D打印机的操作数量减少一半以下，潜在健康风险可降低34.1%，适当的通风可降低潜在健康风险55.5%，远离3D打印机工作也可降低潜在健康风险高达27.5%。本研究分析了实际创客空间中多台FDM-3D打印机对用户的潜在健康风险，并提出了各种改善措施，以降低超细颗粒和细颗粒的潜在健康风险。
Due to the growing maker culture, maker spaces using multiple fused deposition modeling (FDM)-3D printers have spread around the world. However, the 3D printing process is known to cause the release of ultrafine and fine particles, which may have adverse health effects on occupants. Therefore, this experiment-based study was conducted on FDM-3D printers placed in an actual makerspace by the following three scenarios: the number of operating FDM-3D printers, ventilation, and measurement location to compare the concentrations of ultrafine and fine particles. In addition, the deposited dose in alveolar region for ultrafine and fine particles was predicted using a respiratory deposition model to analyze the potential health risk on occupants. As a result, the scenario-based comparison revealed that if the number of operating 3D printers is reduced by less than half, the potential health risk can be decreased by 34.1%, proper ventilation can reduce potential health risk by 55.5%, and working away from the 3D printer can also reduce potential health risk by up to 27.5%. This study analyzed the potential health risk of multiple FDM-3D printers on users in an actual makerspace, and proposed various improvement measures to reduce the potential health risk of ultrafine and fine particles.
