For this purpose, dry blends of glass beads with and without organosilane coupling agents and polyamide powder were prepared and processed into tensile specimens on an EOS P396 laser sintering system. The samples were tested both in the dry state and after an accelerated conditioning in a climate chamber. Furthermore, finite element method (FEM) simulations were performed to model the extreme cases of optimum adhesion and no adhesion. By correlating the tensile tests with the simulation results and by analyzing the fracture surfaces, it was shown that the filler–matrix adhesion is sufficient in the dry state but is strongly degraded by conditioning. Even the presence of various organosilane thin films could not prevent a strong deterioration of the filler–matrix adhesion and the associated deterioration of the mechanical properties. Since a comparison with an injection-molded sample of the same polymer filler combination shows identical behavior after conditioning, it is assumed that this problem is not limited to additively manufactured parts. author: - first_name: Ivo full_name: Kletetzka, Ivo id: '50769' last_name: Kletetzka - first_name: Maren full_name: Kosanke, Maren last_name: Kosanke - first_name: Dennis full_name: Meinderink, Dennis last_name: Meinderink - first_name: Vanessa full_name: Neßlinger, Vanessa last_name: Neßlinger - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Hans-Joachim full_name: Schmid, Hans-Joachim id: '464' last_name: Schmid orcid: 000-0001-8590-1921 citation: ama: Kletetzka I, Kosanke M, Meinderink D, Neßlinger V, Grundmeier G, Schmid H-J.

This has already been investigated intensively by various authors. However, the ageing of the material at ambient temperatures during shelf life has not been the focus so far. The need to analyse the shelf life can be derived from an ecological and economic point of view. This work is focusing on the shelf life of PA2200 (PA12). To reduce the potential influences of powder production fluctuations, two different powder batches stored for 5.5 years and 6.5 years are investigated and compared to a reference powder produced 0.5 years before these investigations. Multiple powder analyses and part characterisations have been performed. A significant yellowing and molecular chain length reduction can be derived from the measurement results. Whereas the influence on mechanical part performance was minor, the parts built with the stored powders are more yellowish. As it is most likely that this is due to the consumption of polyamide stabilisers, it can be assumed that these parts will be subject to significantly faster ageing. Therefore, it is still not recommended to use the stored powders for critical parts or light intense and humid environments. author: - first_name: Sven Helge full_name: Klippstein, Sven Helge id: '71545' last_name: Klippstein - first_name: Ivo full_name: Kletetzka, Ivo id: '50769' last_name: Kletetzka - first_name: Ilknur full_name: Sural, Ilknur last_name: Sural - first_name: Hans-Joachim full_name: Schmid, Hans-Joachim id: '464' last_name: Schmid orcid: 000-0001-8590-1921 citation: ama: Klippstein SH, Kletetzka I, Sural I, Schmid H-J.

One disadvantage of FDM is the shrinkage of the components during the manufacturing process. The filament is molten in the nozzle, deposited layer by layer, and cools down again. During solidification, the filament shrinks inhomogeneously in the x/y/z direction, which leads to distortion of the component geometries. Particularly with higher nominal lengths and complex local geometries, there is a need for optimization with regard to dimensional accuracy. The aim of this paper is to counteract this on the software side with global as well as local shrinkage factors. The expected shrinkage within a layer is predicted with an in-house developed software. The geometric accuracy of the model is verified by experimental investigations on cylindrical test specimens. In these, the so-called clover effect occurs as a result of the shrinkage. The circular shape of the deposited layer is deformed by the distortion in the x–y plane comparable to a clover. Finally, the results are validated by analyzing a demonstrator in the form of a bracket. author: - first_name: Thorsten full_name: Koers, Thorsten id: '38077' last_name: Koers - first_name: Balázs full_name: Magyar, Balázs id: '97759' last_name: Magyar citation: ama: 'Koers T, Magyar B.

A key factor for the further establishment of LS is the expansion of the material portfolio with, for example, refreshable and halogen-free flame-retardant (FR) powder materials. Accordingly, various halogen-free FRs are investigated in this work and evaluated with respect to their use in LS. First, their decomposition behavior and mode of action are examined. Subsequently, the additives are dry blended with PA12 to investigate properties relevant for LS, such as particle morphology, thermal behavior and melt viscosity. Afterwards, test specimens for UL94 vertical flame-retardancy tests are produced by processing the dry blends on an EOS P3 LS system. Finally, the process stability of the process-aged powder blends is investigated by again examining the thermal behavior and melt viscosity. author: - first_name: Fabian full_name: Neitzel, Fabian id: '72307' last_name: Neitzel orcid: '0009-0004-8412-3645 ' - first_name: Ivo full_name: Kletetzka, Ivo id: '50769' last_name: Kletetzka - first_name: Hans-Joachim full_name: Schmid, Hans-Joachim id: '464' last_name: Schmid orcid: 000-0001-8590-1921 citation: ama: 'Neitzel F, Kletetzka I, Schmid H-J.

In the field of laser sintering (LS), these materials are less common so far. In order to extend the available material variety for the LS process, new ceramic-filled Polyamide 613 powders are investigated within the scope of this work. Here, the resulting properties from two different powder production methods are compared. One filled powder is produced by dry blending and the other powder with the same filler and filling ratio is produced by encapsulating the filler particles inside the polymer particles within the dissolution-precipitation process. It was found that encapsulating the filler particles can provide certain benefits for the processability, for example an improved powder flowability or better filler dispersion. However, encapsulating the filler also alters the thermal properties of the precipitated powder.

The principle of the FDM process is the strand wise deposition of molten thermoplastic polymers, by feeding a filament trough a heated nozzle. Due to the strand and layer wise deposition the cooling of the manufactured component is not uniform. This leads to dimensional deviations which may cause the component to be unusable for the desired application. In this paper, a method is described which is based on the shrinkage compensation through the adaption of every single raster line in components manufactured with the FDM process. The shrinkage compensation is based on a model resulting from a DOE which considers the main influencing factors on the shrinkage behavior of raster lines in the FDM process. An in‐house developed software analyzes the component and locally applies the shrinkage compensation with consideration of the boundary conditions, e.g., the position of the raster line in the component and the process parameters. Following, a validation using a simple geometry is conducted to show the effect of the presented adaptive scaling method. author: - first_name: Elmar full_name: Moritzer, Elmar id: '20531' last_name: Moritzer - first_name: Felix full_name: Hecker, Felix id: '45537' last_name: Hecker citation: ama: Moritzer E, Hecker F.
