近年來積層製造(或稱3D列印)技術因其特殊的技術優勢廣泛受到各界矚目, 被視為第三次工業革命中數位製造最重要的一環。積層製造技術擁有可節省材料耗用、絕佳的設計自由度、縮短研發時間、提升後勤效率與解決消失性商源等優勢, 國際航太大廠(如GE、波音、空中巴士)皆陸續導入此技術,美國國防部也期望藉由積層製造技術實現戰場上即時補給的構想。然而,目前積層製造技術仍無法全面取代傳統製造業,工件應先經過適用性評估,才能發揮積層製造技術的最大效益。本文中,將首先介紹積層製造的七大技術,並針對積層製造技術於航太及國防產業之應用實例與未來願景進行論述,最後探討積層製造技術將面臨的潛在挑戰。 In recent years, additive manufacturing(AM, or the so-called 3-D printing) has initiated worldwide interests due to its distinct advantages in fabrication. It is considered as an important step of digital manufacturing in the 3rd industrial revolution. As a result, AM has been widely accepted by international aerospace companies(e.g. GE, Boeing, Airbus) for making a significant impact on the design of complex, custom-made defense and aerospace components that break existing material and engineering limitations. In addition, the U.S. Department of Defense has also tried to realize the concept of real-time supplies on the frontline battlefield by using AM. Since AM still cannot replace the traditional manufacturing processes completely, it is promoted only when the maximum benefits are attainable. In this paper, we first introduce the 7 AM technologies classified by ASTM(American Society for Testing and Materials), then discuss its potential applications in aerospace and defense industries, and finally identify challenges to AM.
