建筑业面临着生产率低下和熟练劳动力日益短缺造成的严重问题。从设计和规划到实际施工过程的所有相关阶段的有目的的数字化和自动化似乎是应对这些紧迫挑战的唯一可行解决方案。添加剂混凝土施工有很大的潜力成为解决方案的关键部分。首先，技术是感兴趣的，这将使大规模的，现场制造的混凝土结构，根据当代建筑和结构设计的要求。本文评估了这些要求的最新技术水平，并介绍了德累斯顿工业大学开发的现场整体3D打印的CONPrint3D概念。这一概念是由施工实践的要求和边界条件驱动的。它符合共同的建筑规范，有效的设计规范，现有的混凝土等级和典型的经济限制。此外，它的目标是最大限度地利用现有的施工机械。作者的跨学科团队阐明了新技术的各种观点：机械工程，混凝土技术，数据管理和施工管理。在这些领域完成的工作中的一些代表性的结果，以及。
The construction industry faces severe problems resulting from low productivity and increasing shortages of skilled labor. The purposeful digitalization and automation of all relevant stages, from design and planning to the actual construction process appears to be the only feasible solution to master these urgent challenges. Additive concrete construction has a high potential to be a key part of the solution. In the first place, technologies are of interest which would enable large-scale, on-site manufacturing of concrete structures in accordance with the demands of contemporary architectural and structural design. The article at hand evaluates the state-of-the-art with respect to these requirements and presents the CONPrint3D concept for on-site, monolithic 3D-printing as developed at the TU Dresden. This concept is driven by the demands and boundary conditions of construction practice. It complies with common architectural norms, valid design codes, existing concrete classes and typical economic constraints. Furthermore, it targets the use of existing construction machinery to the highest possible extent. The interdisciplinary team of authors illuminates various perspectives on the new technology: those of mechanical engineering, concrete technology, data management, and construction management. Some representative results of completed work in these fields are presented as well.
