3D逆向工程於博物館展示之應用：以國立臺灣史前文化博物館為例

Application of 3D Reverse Engineering in Museum Exhibitions: National Museum of Prehistory as an Example

國立臺灣史前文化博物館（以下簡稱史前館）長期投入文物3D數位資料建置工作，是臺灣少數能自行進行3D數位典藏與逆向輸出之博物館。其中臺灣史前史廳常設展更新，利用3D逆向技術製造高精度之文物仿製品，依展示需求與規劃進行模型編修，使其能更配合展示主題及應用不同的展示手法。本文針對史前館3D實驗室執行南科考古館常設展人骨展示更新及特展「我們活過：考古人骨遺骸暨墓葬展」經驗，說明史前館利用3D逆向工程技術於博物館展示之成果，並以康樂本館目前進行展示更新中應用3D列印仿製品的呈現手法，說明3D技術應用於博物館展示之可行性，並嘗試針對製作過程所需的時間與成本、展示應用的差異性、對比傳統模型製作的優勢以及數位發展等議題進行探討。整體而言，3D逆向工程技術可以提供更精確的展示標本仿製成果，減少製作過程打樣與修改的時間，伴隨3D技術的發展將可預期製作成本會持續降低，並能有效因應不同展示環境或手法進行調整，創造更多友善平權的觀展體驗，同時提供數位展示多元應用。

The National Museum of Prehistory (NMP) has long been dedicated to building 3D digital data of artifacts and is one of the few museums in Taiwan that can carry out 3D-digital archiving and reverse-engineering on its own. In the renewed Prehistory of Taiwan Exhibition Hall in NMP, 3D-reverse technology has also been used to create high-precision replicas of artifacts. The models were adapted to suit the needs and plans of the exhibition and can thus fit into different themes and be used in different display methods. This paper illustrates the results of 3D-reverse engineering technology, using the experience of what the 3D Laboratory has done in the renewed exhibition ＂We Were Alive: The Exhibition of Archaeological Human Remains and Burials＂ and the special exhibition of human bones in the Museum of Archaeology, Tainan Branch of NMP as a foundation. The paper also attempts to use the exhibition approaches of 3D-printed replicas in the current exhibition renewal in our Main Site of NMP to illustrate the feasibility of applying 3D techniques to museum exhibitions, discuss the time and cost required during production, the differences in various exhibition applications, the advantages over traditional model-producing methods, and the digital development. Overall, the 3D reverse engineering technique provides more accurately replicated display specimens, reduces proofing and adjusting time during production. With the continuous development of the 3D technique, production costs are expected to decrease, and the technique can be effectively adapted to fit different environments or approaches, creating a more user-friendly and equitable visiting experience, and providing diverse application methods for digital exhibition.
