| 摘要: | 3D列印混凝土是一項創新技術，具有改變建築和施工方式的潛力。其主要優勢包括提高施工速度和減少勞動力需求，以及更靈活的設計能力。透過3D列印，可以創建更複雜和精確的建築結構，這在傳統建築方法中是難以實現的。然而，這項技術目前仍面臨一些挑戰。首先是材料方面的問題，3D列印混凝土需要特定的配方，以確保其在列印過程中具有適當的流動性和固化時間，因此如何選擇正確的材料為重要的一環。若可以在列印前先使用軟體進行分析，則可以減少因材料及結構上的不良選擇而造成的結構物缺陷，進而降低因列印失誤造成的的材料浪費。
本研究旨在使用Abaqus有限元素分析軟體對3D列印混凝土進行模擬，探討不同尺寸、列印速度、形狀和材料對其列印過程及最終結構性能的影響。通過建立不同尺寸的3D列印混凝土模型，分析其應力分布、變形行為及結構穩定性，同時比較不同列印速度和材料對混凝土沙漿結構性能的影響，以確定最佳的列印參數。本研究同時建立了一套系統化的操作流程（Standard Operating Procedure, SOP），為後續研究提供標準化的參考，以提高研究效率和結果的可重複性。另外，本研究基於此套工具，對於3D列印混凝土在不同形狀、列印速度、材料參數等狀況下進行分析以及比較。
本研究開發之Abaqus模擬3D列印混凝土，不僅可以節省實際列印上所需之材料和時間，更可以提高設計的準確性和施工效率，為3D列印混凝土技術的廣泛應用提供有力支持。
;3D printed concrete is an innovative technology with the potential to transform construction methods. Its primary advantages include increasing construction speed, reducing labor demands, and offering greater design flexibility. With 3D printing, it is possible to create more complex and precise architectural structures, which are difficult to achieve with traditional construction methods. However, this technology currently faces several challenges. First, there are material issues: 3D printed concrete requires specific formulations to ensure proper flowability and curing time during the printing process. Selecting the right materials is therefore a crucial aspect. If software analysis is performed before printing, it can help reduce structural defects caused by poor material and structural choices, thereby minimizing material waste due to printing errors.
This study aims to use Abaqus finite element analysis software to simulate 3D printed concrete, investigating the effects of different sizes, printing speeds, shapes and materials on the printing process and the final structural performance. By establishing models of 3D printed concrete with varying sizes, the study analyzes the stress distribution, deformation behavior, and structural stability. Additionally, it compares the effects of different printing speeds and materials on the structural performance of the concrete mortar to determine the optimal printing parameters. A systematic standard operating procedure (Standard Operating Procedure, SOP) is also developed in this study, providing a standardized reference for subsequent research to improve research efficiency and result reproducibility.
The Abaqus simulation of 3D printed concrete developed in this study not only saves the materials and time required for actual printing but also enhances design accuracy and construction efficiency. This provides strong support for the widespread application of 3D printed concrete technology. |
