With additive manufacturing technologies new opportunities for product development arise due to the significant degree of design freedom. On the other hand, the technologies are subject to several limitations concerning the manufacturing accuracy, the maximum component size and the lot sizes. Therefore, for the development of competitive end products, which can be manufactured additively, an adjusted design-approach and changed solution principles are necessary.Solution principles for additively manufactured parts are characterized e.g. by an optimization of their functionality, a lightweight design, a limitation to available materials, production costs reduction and the consideration of the achievable accuracy. Solution principles which are designed for additive manufacturing (DfAM) stick to these boundaries.For this particular research project, a distinction is made between two separate elements of a DfAM. The design of solution principles for additively manufactured parts and the design with solution principles for additively manufactured parts are investigated. In the investigation on the design of DfAM-solution principles a method is created, which enables designers to develop solution principles for simple functions. For the creation of the method, solution principles designed for AM are collected and examined. The collection is expanded by adjusted and within the project developed solution principles.In the investigation on the design with solution principles for additively manufactured parts, a method is created to select single solution principles for the use in a specific product and adapt them to this purpose. For the design with solution principles for additively manufactured parts, the collection of solution principles created before can be used.The aim of the research project is to gain knowledge about elementary properties of AM-compliant solution principles and the function-integrating design with them. The focus is on the methodical approach to the development of solution principles and the development with solution principles under the aspect of the collection of standardized solution principles. The development of a methodical approach is to support the finding of AM-compliant component shapes for the realization of functions by means of additively manufactured components and thus to produce appropriate designs with a high degree of functional integration and a compact design. Furthermore, the methodical support should make the development of additively manufactured components more efficient.

利用增材制造技术，由于设计自由度很大，因此出现了新的产品开发机会。另一方面，这些技术受到制造精度、最大元件尺寸和批量大小等方面的限制。因此，为了开发可增材制造的有竞争力的最终产品，需要调整设计方法并改变解决方案原则。增材制造零件的解决方案原则具有以下特点：通过优化其功能、轻量化设计、可用材料的限制、降低生产成本以及考虑可实现的精度。专为增材制造 (DfAM) 设计的解决方案原则遵循这些界限。对于这个特定的研究项目，DfAM 的两个独立元素之间存在区别。研究了增材制造零件的解决方案原理设计和增材制造零件的解决方案原理设计。在对 DfAM 解决方案原理设计的研究中，创建了一种方法，使设计人员能够开发简单功能的解决方案原理。为了创建该方法，收集并检查了为增材制造设计的解决方案原理。该集合通过调整和在项目内开发的解决方案原理进行了扩展。在对增材制造零件的解决方案原理的设计进行调查时，创建了一种方法来选择用于特定产品的单一解决方案原理并使其适应此目的。对于增材制造零件的解决方案原则的设计，可以使用之前创建的解决方案原则的集合。该研究项目的目的是获得有关符合增材制造的解决方案原则的基本属性及其功能集成设计的知识。重点是在标准化解决方案原则集合方面开发解决方案原则的系统方法以及解决方案原则的开发。系统方法的开发是为了支持寻找符合增材制造标准的组件形状，以通过增材制造组件实现功能，从而产生具有高度功能集成和紧凑设计的适当设计。此外，系统化的支持应该使增材制造组件的开发更加高效。
