The utilization of 'smart' materials with adaptable properties or characteristics are a widespread research issue, offering potential for tailored solutions, weight reduction or added value of products through integrated functionality. Therefore, field controlled hybrid materials such as magnetorheological (MR) elastomers or electrorheological (ER) fluids are particularly valuable and within the focus of science and research. At the same time, additive manufacturing has had a strong influence on production processes over the past decade. Today a 3D printer can be found across all disciplines in almost every company, research institution and even in many private households. The Fused Filament Fabrication (FFF) process is especially popular due to its low cost and simplicity. Within this work, a new approach for the generation of field-structured magnetic elastomers using the FFF process and a correspondingly developed prototype print head for implementation are presented and discussed. With its unique research landscape Dresden offers excellent conditions for the development of innovative processes and composite materials in the field of generative manufacture. In the 'Dresden Concept' network, experts from various disciplines collaborate and investigate the entire spectrum starting from biological materials, through lightweight fibre reinforced polymer composites, to high-temperature ceramics. This article is part of the theme issue 'Patterns in soft and biological matters'.
利用具有适应性特性的“智能”材料是一个广泛的研究课题，通过集成功能为定制解决方案、减轻重量或增加产品附加值提供了潜力。因此，诸如磁流变（MR）弹性体或电流变（ER）流体等场控混合材料特别有价值，并且处于科学研究的焦点之中。与此同时，增材制造在过去十年对生产过程产生了重大影响。如今，几乎在每家公司、研究机构甚至许多私人家庭的所有学科领域都能找到3D打印机。熔丝制造（FFF）工艺因其低成本和简便性而特别受欢迎。在这项工作中，提出并讨论了一种使用FFF工艺生成场结构磁性弹性体的新方法以及相应开发的用于实施的原型打印头实现。德累斯顿独特的研究环境为生成制造领域的创新工艺和复合材料的开发提供了绝佳条件。在“德累斯顿概念”网络中，来自各个学科的专家合作并研究从生物材料开始，经过轻质纤维增强聚合物复合材料，到高温陶瓷的整个领域。本文是主题为“软物质和生物物质中的模式”的一部分。
