摘要

3D列印技術的出現，改變過去傳統的材料切割或去除加工技術，取而代之以材料的堆疊及固化技術來製造產品，而3D列印這個創新技術，將會帶動許多產業供應鏈的重大轉變。本研究以3D列印製程中技術-Material Jetting為研究範圍，藉由專利檢索後，找出關鍵技術，藉以繪製專利功效矩陣圖，並結合發明性問題解決理論(Theory of theSolution of Inventive Problems, TRIZ)矩陣，完成以TRIZ為基之技術功效矩陣圖，藉此看出3D列印製程技術特徵與專利分布情形，並針對解決產品細部設計階段之工程技術矛盾進行研發改善建議。本文發現由TRIZ功效矩陣能有效解決MaterialJetting 技術瓶頸，並提供製造商去進行產品研發創新與專利布局的參考。

The emergence of additive manufacturing (AM) technology gradually replaces traditional manufacturing processes that use material cutting and removal techniques. The innovative technology of AM will bring major changes to the supply chain networks and the models of manufacturing services. Considering material jetting (MJ) as one of the additive manufacturing core process technique with wide applications, this research utilizes patent technology-function matrix and the theory of solution of inventive problems (TRIZ)-based trajectories to explore MJ research and development niches and opportunities. The analytical results of the TRIZ-based technology-function matrix shows that the ＂jetting technique＂ is the most major technology and most MJ patents are related to TRIZ parameters No. 29 ＂Accuracy of manufacturing＂ and No. 32 ＂Manufacturability.＂ In order to solve the contradiction problems simultaneously between the improving parameters ＂No. 9 Speed＂, ＂No.38 Level of automation＂ and the corresponding worsening parameter No.29 ＂Accuracy of manufacturing＂, ＂No. 28. Replacement of a mechanical system＂ and other seven innovative principles can be applied in developing printing heads technique. The analytical results of patent technology portfolios and the transformation of TRIZ parameters help discover critical strategies and directions for MJ researchers and solution providers.
