3D列印是一種數位模型檔案為基礎，能直接製造三維實體的技術。它可用十 分低廉的成本印出客製化及複雜的模型。據此，本研究的目的在於驗證透過非接 觸體表的3D掃瞄與列印技術，來製作透明塑膠面罩的可行性。共計20位健康受 測者參與此研究。在透明塑膠面罩分別透過3D列印模型與傳統石膏模型製作方法 完成後，受測者以一星期為時間間隔，依隨機順序來分別穿戴這兩款透明塑膠面 罩一小時。穿戴一小時後，對受測者進行問卷調查以瞭解穿戴的舒適性與造成臉 部不舒服的部位。結果顯示這兩種製作方法對穿戴舒適性並無顯著的差異，然而 受測者自覺3D列印製模的過程比較舒服。本研究結果顯示利用3D列印技術來協 助治療師製作透明塑膠面罩是可行的方案；此方案對患者而言省時且較舒適。然 而，本研究的限制是缺乏比較臉部燒傷患者穿戴後的感受，未來有待針對此族群 長期穿戴的感受做進一步研究。

3D printing is a process of creating a three-dimensional object i^om a digital file. It allows for printing customized and complicated models with relatively low cost. This study investigated the feasibility of fabrication of transparent face orthosis (TFO) by using a non-contact scanning with 3D printing. Twenty able-bodied participants participated in this study. After fabrication of TFOs by 3D printed mold and conventional plaster mold, participants were assigned to wear these two TFOs. The sequential order of the wearing model was randomly assigned with one-week interval. After one-hour wearing, participants were asked to indicate the comfort level and the discomfort region on face. The results showed that no differences were noticed between these two molds. But participants with 3D printed mold felt much more comfortable during the casting process. 3D printing technology was a promising method to help therapist fabricate the TFO. This method was faster and less stressful for patients. However, one limitation of this study was the lack of comparisons of comfort rating from patients with facial burns. Future research is needed to examine the comfortable rating for burn patients.
