A method for forming a metal vascular stent comprises the steps of: first, establishing a digital image file of a metal vascular stent, using a software to perform cutting and layering, setting processing parameters such as a laser scanning path, and then performing a laminate manufacturing forming process. The laminate manufacturing forming process includes: providing a forming platform on which a metal powder layer is coated and formed in a leveled distribution with a thickness approximately the thickness of the cutting layer preheating the metal powder layer of the forming platform in a low oxygen concentration working environment, and using laser to selectively scan and sinter the metal powder layer according to the setting of said processing parameters, so as to form a first layer of the metal vascular stent afterwards, lowering the forming platform by a height roughly equal to the thickness of said cutting layer, and repeatedly applying said steps of coating metal powder and laser scanning/sintering to form another layer of said metal vascular stent repeating the steps of lowering the forming platform, coating the metal powder layer and the laser scanning/sintering to obtain other layers of the metal vascular stent until the topmost layer is completed, thereby manufacturing a formed blank of the metal vascular stent and next, the formed blank surface is optionally performed with electrolytic polishing or anodizing treatments for optimizing the surface of the metal vascular stent.一種金屬血管支架成型方法,包含:先是建立金屬血管支架的數位圖檔,並使用軟體進行切割分層,以及產生雷射掃描路徑等加工參數的設定,然後據以進行積層製造成型製程,所述積層製造成型製程包括:提供一成型載台,在該成型載台上塗佈形成一平整分佈的金屬粉末層,該金屬粉末層厚度約為所述切割分層的厚度;在低氧濃度作業環境下對該成型載台的金屬粉末層進行預熱,然後使用雷射依照所述加工參數之設定,選擇性地對所述金屬粉末層進行掃描燒結,形成金屬血管支架的第一層片;然後,令所述成型載台往下降低高度約一所述切割分層的厚度,並重複實施前述塗佈金屬粉末層及雷射掃描燒結步驟,以形成金屬血管支架的另一層片;再重覆實施前述成型載台下降、塗佈金屬粉末層及雷射掃描燒結之步驟,以獲得金屬血管支架的其他層片,並直到完成最頂的層片為止,製成所述金屬血管支架的成型胚體;接續,可選擇的對所述成型胚體表面進行電解拋光加工或陽極處理,優化金屬血管支架的表面。12‧‧‧成型載台13‧‧‧成型區腔體3‧‧‧雷射4‧‧‧成型胚體4n‧‧‧最頂層片
