本文为 3DCP（3D 混凝土打印）和 UHPC（超高性能混凝土）的研究，旨在在 相關文獻的支持下，为日常測試實踐與該領域的最新進展之間建立聯繫。最初也是 關鍵的一步是獲得本構模型，這是理解力學行為和確定研究方向的基礎。利用 FEM （有限元法）軟件中的 NC（普通混凝土）模型可以模擬各種結構測試，例如壓 縮、拉伸、彎曲、劈裂和扭轉。通過分析這些行為，研究人員成功地確定了一種本 構模型，可以準確地複制在 UHPC 中觀察到的力學現象。
3DCP 和 3D UHPC 已在各個行業得到廣泛應用，包括建築、施工、土木工程 和基礎設施開發。該技術能夠創建各種結構，從微型裝飾節點到大型建築構件，如 牆壁、地板，甚至整個房屋。 3DCP 涉及利用大型 3D 打印機增材製造用於建築結 構的混凝土基材料。該過程通常從在計算機上創建虛擬結構開始，然後將其分割成 所需的結構或組件。隨後，施工現場安裝了一台 3D 打印機來增材濕混凝土層，逐 漸形成最終產品。

This paper presents the investigation on 3DCP (3D Concrete Printing) and UHPC (Ultra-high Performance Concrete), aiming to establish a connection between everyday testing practices and recent advancements in the field, as supported by relevant literature. The initial and crucial step involves obtaining the constitutive model, which serves as the foundation for understanding mechanical behavior and determining the direction of research. The utilization of NC (Normal Concrete) models in FEM (Finite Element Method) software enables the simulation of various structural tests, such as compression, tension, bending, splitting, and torsion. Through analyzing these behaviors, researchers have successfully identified a constitutive model that accurately replicates the mechanical phenomena observed in UHPC.
3DCP and 3D UHPC have found widespread application across various industries, including architecture, construction, civil engineering, and infrastructure development. The technology enables the creation of a wide range of structures, from micro decorative nodes to great building components such as boards, walls, floors, and even entire houses. 3DCP involves the utilization of large-scale 3D printers to additively manufacture concrete-based materials for building structures. The process typically starts with creation of virtual structures on a computer, which is then segmented into the desired structure or component. Subsequently, a 3D printer is installed at the construction site to deposit layers of wet concrete, gradually building up the final product.
