金屬平板製造之數位構築

金屬良好的結構強度和耐候性等優點讓其成為更加廣泛應用的建築材料，可回收再利用、總量不會耗損的特性更讓其成為未來趨勢中的主流永續材料。但由於金屬的加工難度較高，今日建築上對於金屬的應用還大多是處在鋼筋混凝土等侷限性較大且較為制式化的運用。在全球化發展的浪潮下，數位設計的發展越來越先進，配合數位加工技藝，將會使金屬在建築上的運用越來越靈活與自由。本研究嘗試由傳統的手工鈑金到數位加工手法的實驗，探討結合各種不同金屬的手工與數位加工技術，讓金屬應用更為多元化，並嘗試將工法應用於構築建造當中，透過建造1:1的實驗性實構築來研究與探討金屬材料及構造。論文通過文獻回顧以案例學習討論數位製造在金屬構築上之應用，分析構築方式與加工方法，應用於後期設計之中。第三四五章分別為CNC金屬折疊，SPIF單點漸進成型以及英國輪輥軋三種工法類型的試做，個別進行不同工法的試驗與改良，然後根據需求分別進行一些小規模的前置設計，分析和總結之後將製造經驗沿用至1:1實構築設計當中。最後透過製作實際尺度的構築來驗證結構性與施做之可行性。最後為回顧前面章節之內容與設計操作心得，檢討過程中的缺失與可改善之處，並提出後續研究之建議與方向。尋找金屬在建築中的可能性，以1:1構築來驗證可行性，是本研究所設定的目標。當傳統金屬技術與數位設計製造相結合，不僅能使得金屬板材的設計加工製造門檻降低，還能讓金屬於建築上的運用跳脫出制式的設計，產生出更加多元的組構形態。

The structural strength and weather resistance property are a few of the reasons why metal is so widely used as a building material in the construction industry. In addition, metal’s ability to be reused without losing mass allows it to become one of the major sustainable materials of the future. However, due to the difficulty of metal processing, the application of metal in today’s architecture is strictly seen in typical large scale reinforced concrete structures or standardized constructions. As globalization spreads and digital design becomes more and more prevalent, metal coupled with the advancement of digital technology will lead to more flexible and creative designs in metal processing. This research will use traditional handmade sheet metal and digital processing to explore the different combinations of metal processing techniques. Furthermore, an attempt will be made to apply the processing methods into real-world building construction through the design of a 1:1 scale model. This model will serve as the constant in which a thorough study of the materiality of metal and its properties will be tested. The thesis will be conducted through literature reviews and case studies that discuss the use of digital fabrication of metal in the construction industry. Further emphasis will be placed on the analysis of building construction and processing types which will be used in a later phase. The third, fourth, and fifth chapters will each address a specific kind of metal processing, their respective testing and ways to improve the process. The first topic will tackle the folding of metal sheets using CNC machines. The second topic will discuss the single point incremental forming (SPIF) of metal, while the third topic will be a deep dive into the UK metal forging process. Depending on the needs of each process, preliminary designs will be tested and with the analyzed results, a 1:1 scale model will be developed and implemented into the construction design. Lastly, through the creation of a life-size building part; the structural capabilities and construction possibilities of metal can be verified. Finally, the contents in the initial design execution phase in previous chapters will be reviewed to find any mistakes and rooms for improvement in order to propose suggestions and research direction for future scholars. The objective of this research is to explore the possibilities of metal application within the field of architecture using 1:1 scaled model. When digital fabrication is integrated with traditional metal technology, not only will this lower the overall threshold for metal processing; it will also allow metal in architecture to leap out of its current systematic usages and into a role that can createsmore complex structural forms.
