Einsatz von Additive Manufacturing zur Darstellung von Simulationsergebnissen in der Blechumformung
(2016)
Virtuelle Modell "begreifbar" Machen - Darstellung von Simulationsergebnissen mittels 3D-Farbdruck
(2016)
Additive manufacturing (AM), or 3D printing (3DP), has increasingly become more wide-spread and applied to a great degree over the past years. Along with that, the necessity for training courses which impart the required knowledge for product development with 3D printing rises. This article will introduce a “Rapid Prototyping” workshop which should convey to students the technical and creative knowledge for product development in using additive manufacturing. In this workshop, various 3D printers are initially installed and put into operation for the construction of self-assembly kits during the introduced training course. Afterwards, the students use databanks to select and download suitable components for the 3D print on the basis of criteria. Lastly, the students develop several assembly kits independently and establish design guidelines based on their experience. The students likewise learn to estimate and evaluate economic boundaries such as, e.g. costs and delivery times. For a start, it is a new approach to be using various assembly kits. These are up to date with current technology and dispose of features such as, e.g., additional nozzles for support material and heated building platforms. Moreover, a comprehensive evaluation of the training success will be conducted. The students’ level of knowledge in various areas will also be determined and compared with surveys taken before and after the conducting of the workshops. Additionally, cost and delivery time estimates and knowledge of databanks will be determined through concrete questioning.
A number of design rules must be adhered to in the development and manufacturing of unmanned aerial vehicles. In this, additive manufacturing, particularly in the implementation of requirements with respect to light-weight construction and sustainability, offers several advantages compared to conventional manufacturing methods. Therefore, this article will primarily introduce and compare current concepts for sustainable design using additive manufacturing. These will, above all, consist of the production of complete fuselages and wings by means of rapid prototyping or also rapid tooling. In addition, a new concept will be introduced in which a UAV using AM can be implemented through the combination of very light components and a preferably resource-saving manufacturing method. In this process, a three-dimensional spaceframe is used in combination with a covering in the construction of the wing. Hereby, the development process for sustainable design using additive manufacturing will be analyzed and the results will be explained by means of concrete case studies. In conclusion, the results of these case studies will be compared to the latest technology regarding wing span load.
In addition to traditional methods in product development, the increasing availability of two new 3D digital technologies, namely digital manufacturing (3D-printing) and digitizing of surfaces (3D-scanning), offer new opportunities in product development processes today. With regard to the systematic implementation of these technologies in the education of students in the field of product development, however, only a small number of approaches exist so far. This paper explores several ways in which 3D digital technologies can productively be used in design education. The innovative aspects here include that the students assemble and install the 3D-printers themselves, and that they are introduced to an approach that combines 3D-scanning followed by 3D-printing.
This paper presents a new approach for the teaching of competence in additive manufacturing to engineering students in product development. Particularly new to this approach is the combination of the students' autonomous assembly and commissioning of a 3D-printer, and the independent development of guidelines for this new technology regarding the design of components. This way the students will be able to gain first practical experiences with the data preparation, the additive manufacturing process itself and also the required post-treatment of the 3D-printed parts. To allow the students a significantly deeper insight into the functioning of 3D-printing, the workshop Rapid Prototyping developed a new approach in the course of which the students first assemble a construction kit for a 3D-printer themselves and then commission the printer. This enables the students to gain a better understanding of the functionality and configuration of additive manufacturing. In a next step, the students used the 3D-printers they constructed themselves to produce components which they take from a database. Finally, the experiences of the students in the course of the workshop will be evaluated to review the effectiveness of the new approach.
In addition to traditional methods in product development, the increasing availability of additive manufacturing AM technologies offer new opportunities in product development processes today. This contribution explores several ways in which AM can productively be used in education. New to this approach is amongst others that the students assemble and install the 3D-printers themselves. In two case studies is demonstrated how students in design education are able to autonomously research and realize technical possibilities and limitations of AM technologies, as well as economic constraints.
Application of Polymer Plaster Composites in Additive Manufacturing of High-Strength Components
(2015)
Today, 3D-printing with polymer plaster composites is a common method in Additive Manufacturing. This technique has proven to be especially suitable for the production of presentation models, due to the low cost of materials and the possibility to produce color-models. But nowadays it requires refinishing through the manual application of a layer of resin. However, the strength of these printed components is very limited, as the applied resin only penetrates a thin edge layer on the surface. This paper develops a new infiltration technique that allows for a significant increase in the strength of the 3D-printed component. For this process, the components are first dehydrated in a controlled two-tier procedure, before they are then penetrated with high-strength resin. The infiltrate used in this process differs significantly from materials traditionally used for infiltration. The result is an almost complete penetration of the components with high-strength infiltrate. As the whole process is computer-integrated, the results are also easier to reproduce, compared to manual infiltration. On the basis of extensive material testing with different testing specimen and testing methods, it can be demonstrated that a significant increase in strength and hardness can be achieved. Finally, this paper also considers the cost and energy consumption of this new infiltration method. As a result of this new technology, the scope of applicability of 3D-printing can be extended to cases that require significantly more strength, like the production of tools for the shaping of metals or used for the molding of plastics. Furthermore, both the process itself and the parameters used are monitored and can be optimized to individual requirements and different fields of application.
Additive Manufacturing and Reverse Engineering have increasingly been gaining in importance over the past years. This paper investigates the current status of the implementation of these new technologies in design education and also identifies current shortcomings. Then it develops two new approaches for the teaching of the necessary expertise for the design of 3D-printed components and illustrates these with case studies. First, a workshop is presented in which students gain a broad understanding for the functionalities of additive manufacturing and the creative possibilities and limits of this process, through the assembly and installation of a 3D-printer. A second new approach is the combination of reverse engineering and 3D-printing. Thereby, students learn how to deal with this complex process chain. The result of these new approaches can e.g. be seen in the design guidelines for Additive Manufacturing, which were developed by the students themselves. At the same time, the students are able to estimate opportunities and limits of both technologies. Finally, the success of the new course contents and form is reviewed by an evaluation by the students.
Various rapid prototyping methods have been available for the production of physical architectural models for a few years. This paper highlights in particular the advantages of 3D printing and Fused Layer Modeling for the production of detailed architectural models. In addition, the current challenges for the creation and transfer of CAAD-data are explained. Furthermore, new methods are being developed in order to improve both the technical and economic boundary conditions for the application of 3DP und FLM. This makes the production of models with very detailed interior rooms possible. The internal details are made visible by dividing the complex overall model into individual models connected by means of an innovative plug-in system. In addition, three case studies are shown in which the developed methods are applied in order to implement detailed architectural models. Finally manufacturing time and costs of the architectural models in the three case studies are compared.

In addition to traditional methods in product development, the increasing availability of two new technologies, namely additive manufacturing AM (e.g. 3D-printing) and reverse engineering RE by means of 3D-scanning, offer new opportunities in product development processes today. However, to date only very few approaches exist those include these new technologies systematically in the education of students in the field of product development. This paper explores several ways in which AM and RE can productively be used in education. New to this approach is, on the one hand, that the students assemble and install the 3Dprinters themselves, and on the other hand, that they are introduced to an approach that combines 3D-scanning followed by 3D-printing. In different case studies is demonstrated that students in design education are able to autonomously research and realize technical possibilities and limitations of these technologies, as well as economic parameters and constraints.
