This invention provides a supporting vest and constructing method thereof. The supporting vest is designed as one-piece to simplify component-based construction. A 3D scanner is utilized to scan a subject to obtain parameters for an auto-model ing program, which help to manufacture an optimized supporting vest for the subject by printing rather than manually assembling. The subject can easily put on the supporting vest without detailed steps.本發明提供一種固定架背心及其建構方法,固定架背心設計為一體成型結構以簡化組成構件,並可利用3D掃瞄機掃瞄人體參數,帶入自動化建模程式,幫每個病患"量身訂做"一套固定架背心,並在短時間內快速列印出一套穿戴方便的固定架背心,組裝上不需耗費太多人力,病患直接套上即可。1‧‧‧固定架背心10‧‧‧頂環11‧‧‧固定部110‧‧‧第一連接孔111‧‧‧固定孔20‧‧‧支撐架21‧‧‧連接部210‧‧‧第二連接孔30‧‧‧背心40‧‧‧束帶41‧‧‧扣合部
