3D Printing (3DP) technology, one of the layered production methodologies where design and construction configurations can be made with increasing digitalization and Industry 4.0, is one of the leading techniques of the period. 3D Concrete Printing (3DCP) also comes to the fore in the construction industry. The study aims to observe the impact of architectural design decisions on the 3DCP process by developing controlled and consistent design alternatives. Architectural designs developed with different geometric forms in the housing function were subjected to digital planning, 3DCP preparation, and 3DCP prototype final product stages. In the integration of design and 3D concrete printing (3DCP), two key aspects were investigated: (i) the impact of different geometric forms (square, rectangle, hexagon, octagon, circle, and ellipse) on the buildability performance of 3D-printed structures, and (ii) how variations in design details influence printing time, material consumption, cost, and the feasibility of mass production in architectural applications. For the 3DCP process, 3D-printable cementitious mixture was developed, and a 3D printer with dimensions of 100 x 100 × 40 cm was used. The results obtained during the printing process were analyzed in comparison with the building evaluation parameters. As a result, the house with circular geometry showed the optimum behavior according to the parameters of buildability, cost, and mass producibility. The circle geometric form provides a 4.2 % advantage over the octagon in terms of buildability, a 16.6 % advantage over the ellipse in terms of cost, and a 20 % advantage over the ellipse in terms of mass producibility.

3D 混凝土打印技术在房屋不同建筑设计决策下的建筑施工中的适用性


3D 打印 （3DP） 技术是分层生产方法之一，随着数字化和工业 4.0 的提高，可以进行设计和施工配置，是当时的领先技术之一。3D 混凝土打印 （3DCP） 在建筑行业也脱颖而出。该研究旨在通过开发受控且一致的设计替代方案来观察建筑设计决策对 3DCP 流程的影响。在房屋功能中使用不同几何形状开发的建筑设计经过数字规划、3DCP 准备和 3DCP 原型最终产品阶段。在设计和 3D 混凝土打印 （3DCP） 的集成中，研究了两个关键方面：（i） 不同几何形状（正方形、矩形、六边形、八边形、圆形和椭圆形）对 3D 打印结构的可建造性性能的影响，以及 （ii） 设计细节的变化如何影响打印时间、材料消耗、成本和建筑应用中大规模生产的可行性。对于 3DCP 工艺，开发了 3D 打印的水泥基混合物，并使用了尺寸为 100 x 100 × 40 厘米的 3D 打印机。将打印过程中获得的结果与建筑物评估参数进行比较进行分析。结果，具有圆形几何形状的房屋根据可建造性、成本和质量可生产性参数表现出最佳行为。圆形几何形状在可建造性方面比八边形高 4.2%，在成本方面比椭圆高 16.6%，在质量可生产性方面比椭圆高 20%。
