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.

随着增材制造技术的发展，由于设计自由度的显著提高，产品开发出现了新的机会。另一方面，这些技术受到制造精度、最大组件尺寸和批量大小等方面的限制。因此，为了开发具有竞争力的可增材制造终端产品，需要调整设计方法和改变解决原则。增材制造零件的解决方案原则的特点是：优化其功能、轻量化设计、限制可用材料、降低生产成本和考虑可实现的精度。为增材制造（DfAM）设计的解决方案原则遵循这些边界。对于这个特殊的研究项目，对DfAM的两个独立元素进行了区分。研究了增材制造零件求解原则的设计和增材制造零件求解原则的设计。在对dfam -求解原则设计的研究中，创建了一种方法，使设计人员能够为简单的功能制定求解原则。对于该方法的创建，收集并检查了为AM设计的解决原则。该集合通过调整和项目开发的解决方案原则进行扩展。通过对增材制造零件解决原则设计的研究，提出了一种选择单一解决原则并使之适应于特定产品的方法。对于具有增材制造零件解原则的设计，可以使用之前创建的解原则集合。本研究项目的目的是了解am相容解原理的基本性质，并利用它们进行功能集成设计。重点是在标准化解决方案原则集合的情况下，对解决方案原则的系统化开发和解决方案原则的开发。系统方法的发展是为了支持通过增材制造组件实现功能的am兼容组件形状的发现，从而产生具有高度功能集成和紧凑设计的适当设计。此外，系统的支持应该使增材制造部件的开发更有效率。
