[{"abstract":[{"text":"Purpose – This paper aims to present a methodology to help end-users to find appropriate part candidates for the use of the additive manufacturing (AM) technology. These shall be capable of bringing AM into their businesses. The concept furthermore includes approaches for redesigning current available parts and helps to estimate the economic implications of the use of the technology. Design/methodology/approach – The approach starts to discuss general economic aspects for the successful use of AM. While describing the introduction of new technologies into existing businesses, the importance of an appropriate part selection for AM is pointed out. A methodology for a part selection process is presented, and the different criteria are developed. An approach for a redesign of the selected parts, including the gathering of requirements, is given based on different sample parts. A variation of criteria to include measures for product piracy is highlighted. Findings – The methodology has proven applicability in several research and industry projects in aerospace applications. Independent part selections from experts analyzed within a project of the European Space Agency had a 90 per cent overlap with the results. It allows companies with only basic AM knowledge to start a part screening for applicable AM candidates in their own company with a reasonable effort. Originality/value – The methodology for the redesign process helps to identify the main functions of the products targeted and the relevant environment, so one can benefit from the various advantages that AM has to offer. The selection methodology helps to ask the right questions and to reduce the effort.","lang":"eng"}],"status":"public","type":"conference","publication":"Rapid Prototyping Journal","language":[{"iso":"eng"}],"_id":"21683","user_id":"55833","department":[{"_id":"144"},{"_id":"219"},{"_id":"624"}],"year":"2015","citation":{"chicago":"Lindemann, C., U.

Here AM is often mentioned as a driver for product piracy as it allows to produce and to copy objects with any geometries. Imitators need a lot of information to copy an object accurately. As reverse engineering has been identified as the most important information source for product imitators, AM can also help to reduce the threat of product piracy when correctly applied in the product development. Due to the layer wise production process that allows the manufacturing of very complex shapes and geometries, the reverse-engineering process can be complicated by far. By this, quite contrary to the public opinion, AM can increase the needed effort of imitators and strongly reduce the economic efficiency of product piracy. This paper will show different protection measures and a methodological approach of how to apply these measures to a product. Beside the protective effect some measures allow a traceability of parts over the product’s lifecycle and thus support the quality management of AM processes and additively produced parts.

Especially in combination with FE-based topology optimization an optimal use of material and thus significant weight reductions can be expected. However, the application of AM is hampered by different additional manufacturing processes along the entire production chain and data handling induced restrictions.Disadvantages emerge from a lack of adjustment of the entire design process for AM. First the optimization algorithms are not targeted to the opportunities and restrictions of AM –represented by design rules – like the design of support structures. Secondly, the CAD software is not adjusted to AM in particular. Creating freeform shaped surfaces based on the optimization results is significantly less convenient than building defined blocks or turning parts following the needs of conventional machining. The indispensable subsequent interpretation of optimization results regarding the design rules and the possibilities of CAD-tools counteracts optimal results. This paper considers different approaches for a Topology Optimization (TO)-shape regaining on different sample parts including telecommunication satellite parts. An innovative design methodology is presented getting crucial for creating high quality designs.

The knowledge of the mechanical properties is very important for the design engineer when it comes to the component design. End-use products out of the FDM process have to resist applied forces. In this paper, investigations were conducted with the polymer Polyamide 12 (FDM Nylon 12) from Stratasys Inc. This polymer can be processed with three different tip sizes resulting in different layer thicknesses from 178 µm to 330 µm. Thus, the mechanical properties were determined for these layer thicknesses and for different orientations on the build platform.

In this process, parts are manufactured layerwise out of a polymer powder by laser exposure. After the building process, these parts are located within a loose bulk powder cake. Due to long process times and high process temperatures, this powder ages thermally, which reduces the recyclability of the material. As a result, mixtures of used and virgin powder (\"refreshed\" powder) with a mixture ratio of approximately 50% are commonly used in the industry. The goal of this work is to determine the exact influence of different powder ages on resulting part quality characteristics, especially the mechanical behavior and the surface quality. Therefore, refreshed powder with different qualities adjusted by the melt volume rate (MVR) was processed along a defined process quality chain. To analyze the part qualities, mechanical tensile and profilometer tests were performed. The focus is on an application-oriented test set-up to ensure the usability of the results in the industry. The material used is polyamide 12 (PA 2200) processed on an EOSINT P395 laser sintering system from EOS GmbH, Krailling, Germany.","lang":"eng"}],"status":"public","_id":"22184","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"user_id":"71545","language":[{"iso":"eng"}]},{"status":"public","abstract":[{"text":"The process-related occurrence of varying cooling rates at different positions within the part cake is an important challenge regarding the part quality and reproducibility of the polymer laser sintering process. Temperature history dependent parameters are for example the part warpage, the crystallization behavior or powder ageing effects, which have to be considered for optimized process controls. Nevertheless, the inner temperature distribution and history during the cooling process is difficult to measure and less known yet. In this work, a Finite Element (FE) model is developed to understand and predict the temperature distribution and history within the part cake during the cooling process. Therefore, the thermal boundary conditions of a laser sintering system are analyzed and relevant parameters are identified. A basic FE model is set up in ABAQUS CAE software considering a part-free powder cake. Important thermal parameters of the bulk powder and the environment are adjusted and verified in relation to experimental in-process measured data. With this model it is possible to predict position-dependent cooling rates as a function of significant job parameters, for example the job height or the environmental conditions during the cooling phase. In combination with extended in-process temperature measurements and a consideration of built parts, this model will be an important tool for the development of optimized process controls.","lang":"eng"}],"publication":"International Conference on Additive Technologies","type":"conference","language":[{"iso":"eng"}],"department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"user_id":"71545","_id":"22193","intvolume":"         5","page":"222-227","citation":{"apa":"Josupeit, S., Ordia, L., &#38; Schmid, H.-J.

Profound changings of the existing processes can be expected for the area of Maintenance, Repair and Overhaul (MRO) as well. It is described with the help of scenarios which chances result from the integration of this technology while different applications are considered. It starts with the implementation of AM as another manufacturing technology for the repair of spare parts. The precision reduces the effort for post-processing in comparison to the conventional manufacturing methods such as the build-up welding. If an unexpected part breakdown occurs and the aircraft has to stay on ground, there are high demands on the logistics to deliver the required spare parts from the warehouse as fast as possible. The storage of spare parts causes extremely high costs and can be considerably reduced with the help of Additive Manufacturing. Distributed generative manufacturing centers can lead to a far-reaching restructuring of the existing processes where the required spare part is manufactured locally on demand. The resulting opportunities and risks for the involved market actors are shown within the presentation. It is described how MRO service providers and OEMs are affected by that and which changes of today’s processes are necessary to implement the presented scenarios."}],"status":"public","type":"journal_article","publication":"Rtejournal","title":"Exploring the influence of an Additive Manufacturing integration on future MRO processes in aeronautics","doi":"https://www.rtejournal.de/ausgabe11/3958","date_updated":"2022-01-06T06:55:11Z","date_created":"2021-04-21T07:45:03Z","author":[{"first_name":"G.","full_name":"Deppe, G.","last_name":"Deppe"},{"last_name":"Koch","full_name":"Koch, R.","first_name":"R."}],"volume":2014,"year":"2014","citation":{"apa":"Deppe, G., &#38; Koch, R.
