Due to the population growth and increasing scarcity of natural resources, the construction industry is faced with the task of building more with less material. In this context, the contribution of DFG Priority Programme 2187 is of a great social relevance. By accelerating production processes, more can be built in less time. The required high precision also allows design and implementation of components that can fulfill their tasks with a minimum use of material. The declared goal of the planned SPP 2187 "Adaptive modular construction methods with flow manufacturing methods" is interactive, industrialized construction on the basis of modular structures. Modular structures should secure properties such as adaptability, changeability and sensory intelligence for the parts as well for the whole system through the production based on a new line assembly methodology. In industrial manufacturing technology, additive manufacturing is regarded as a key technology for achieving these goals. If one wants to compete with industrial manufacturing technology, so it is advisable to make such processes available for the construction industry, even if line assembly itself is not yet the widespread practice in that field. It has now been recognized that the manufacture of individual, scalable products, based on modules with equal individual properties and using additive manufacturing processes, can be successful. The definition of unit boundaries and the connecting interfaces are relevant factors for the production of modules within this manufacturing approach. Those factors fundamentally determine the quality of the modules, incl. achievable assembly accuracy, application of reinforcing materials, quality of the information about components, formability, etc. The participating research institutes see themselves in this new research approach as a key link in reforming the concrete construction in accordance with the information flow within the line assembly processes. The basis for that is the newly developed hydroplotting method, which makes it possible to produce spatial, fully recyclable formwork by selectively injecting water into a mixture of sand and organic binder along a specified path. Further subsequent processes produce stable formwork, which can be dissolved by the adding the water inside it and repeatedly used afterwards. By coupling this process of the formwork production with an additive production in such a way that these two methods can be combined as one layered process, it becomes possible to produce individual, structurally adaptable and fibre-reinforced modular components.

由于人口增长和自然资源的稀缺性越来越大，建筑业面临着更少的材料来建造更多的任务。在这种情况下，DFG优先计划2187的贡献具有很大的社会意义。通过加速生产过程，可以在更少的时间内构建更多。所需的高精度还允许设计和实施可以通过最少使用材料来完成其任务的组件。计划中的SPP 2187“具有流量制造方法的自适应模块化构造方法”的宣告目标是基于模块化结构的交互式工业化构造。模块化结构应确保零件的适应性，可变性和感官智能，以及通过新系统组装方法来为整个系统提供的零件。 在工业制造技术中，增材制造被视为实现这些目标的关键技术。如果一个人想与工业制造技术竞争，那么建议将这样的流程用于建筑行业，即使线路组装本身尚未在该领域的广泛实践。现在已经认识到，基于具有平等单个属性并使用增材制造过程的模块的单个可扩展产品的制造可以成功。单位边界和连接界面的定义是该制造方法中模块生产的相关因素。这些因素从根本上决定了模块的质量，包括。可实现的组装精度，加强材料的应用，有关组件的信息的质量，可调节性等。参与的研究机构将自己视为这种新的研究方法，这是根据线组装过程中的信息流进行改革的关键联系。 这样做的基础是新开发的水流方法，这可以通过选择性地将水注入指定路径的沙子和有机粘合剂的混合物中，从而产生空间，完全可回收的模板。随后的进一步过程产生稳定的模板，可以通过将其添加的水溶解并反复使用。通过将这种模板生产的过程与添加剂产生结合，以使这两种方法可以与一个分层过程结合在一起，就可以产生个体，结构适应性和纤维增强的模块化组件。
