智慧機械與數位製造3D列印的發展

Development of Smart Machinery and Digital Manufacturing with 3D Printing

3D列印不只是過去的快速打樣，已為全球推動「工業4.0」及「智慧機械」的重要技術之一，涵蓋機械、光電、材料及資訊，至後端創新應用及商業服務等，為一種創新製造模式，使傳統製造方式邁入高客製化量產數位製造技術時代，而在3D列印技術中，若將材料圖案成形及能量提供控制分開，將可而達到高速與高精度的數位製造技術，其中以黏著劑噴印成型法及光固化樹脂成型法可透過高速多噴嘴或數位光源定義成形位置精度，高熱能或紫外光能快速使材料於所定義位置成形的優勢，甚至極高功率雷射直接快速沉積，並於單一機台完成，兼具自動化及功能性材料選擇的效能與優勢，達到高速度與高精度之數位製造方法。

3D printing is not just a rapid prototyping in the past, it is now one of the important emerging technologies in ＂Industry 4.0＂ and ＂Smart Machinery＂ worldwide, which is covering mechanics, optoelectronics, materials and information, to innovative design and manufacturing of the applications and new business service model. This innovative manufacturing process brings traditional manufacturing methods into the era of highly customized mass production digital manufacturing technology. In 3D printing technology, if the material pattern formation and energy supply control are separated, high-speed and high-precision digital manufacturing can be achieved. Among of 3D printing technology, binder jetting and liquid VAT photopolymerization techniques, in which the adhesive spray printing method and the light enhanced resin curing method, can define the accurate forming position through a high-speed multi-nozzle or a digital light source, and apply thermal energy or ultraviolet light source to materials at the defined position. It can be completed on a single machine with extremely direct high laser power for quick deposition and combine both efficiency and advantages of automatic manufacturing and functional materials to achieve high speed and high precision digital manufacturing.
