The components are produced by depositing fine, molten plastic droplets. The main advantage of the APF is the open-parameter control of the associated machine system. Thus, the process parameters can be optimized for individual applications. A special and new application of the APF is the production of interconnecting porous structures. As this is a novel approach with this manufacturing process, the general producibility and reproducibility must first be proven. Therefore, the relevant process parameters with an influence on the open-pored structures are identified. The volume of the individual plastic droplets, the distance between the droplets and the layer thickness are the three decisive influencing factors. With the use of analysis methods, the free spaces created in the structure are described by a uniformly constructed, interconnected pore structure. This means that the pores are interconnected in three dimensions. Reproducibility is evaluated by repeated production and thru the changed conditions during the manufacturing process. In addition, the multiplication and a change of geometry are evaluated in such a way that there is no influence on the pore size. Irregularities when depositing the first layer are caused by unevenness of the building platform. A suitable test arrangement is set up to determine the liquid permeability. A characteristic value is determined to describe the permeability to liquids.}}, author = {{Moritzer, Elmar and Hirsch, André and Dalmer, C.}}, isbn = {{978-3-030-54333-4}}, pages = {{112--129}}, publisher = {{Springer}}, title = {{{Investigation of Plastic Freeformed, Open-Pored Structures with Regard to Producibility, Reproducibility and Liquid Permeability}}}, doi = {{10.1007/978-3-030-54334-1}}, year = {{2021}}, } @article{24162, author = {{Moritzer, Elmar and Wächter, Julian and Elsner, Christian Lennart}}, journal = {{Macromolecular Symposia}}, number = {{1}}, publisher = {{Wiley}}, title = {{{Investigation of Specific FDM Process Parameters to Optimize the Polymer Discharge of Carbon Fiber Reinforced PEEK}}}, doi = {{10.1002/masy.202000269}}, volume = {{395}}, year = {{2021}}, } @article{24681, author = {{Moritzer, Elmar and Schumacher, Christian}}, issn = {{1022-1360}}, journal = {{Macromolecular Symposia}}, number = {{1}}, title = {{{Stainless Steel Parts Produced by Fused Deposition Modeling and a Sintering Process Compared to Components Manufactured in Selective Laser Melting}}}, doi = {{10.1002/masy.202000275}}, volume = {{395}}, year = {{2021}}, } @inproceedings{24554, author = {{Moritzer, Elmar and Elsner, Christian Lennart and Wächter, Julian and Knoop, Frederick}}, booktitle = {{79th Annual Technical Conference of the Society of Plastics Engineers (ANTEC)}}, title = {{{Investigation and Realization of Watertight FDM Structures Made of Ultem 9085 in Pressurized Systems}}}, year = {{2021}}, } @article{23867, abstract = {{The joining of plastics is required because component geometries are severely restricted in conventional manufacturing processes such as injection molding or extrusion. In addition to established processes such as hot plate welding, infrared welding, or vibration welding, hot gas butt welding is becoming more and more important industrially due to its advantages. The main benefits are the contactless heating process, the suitability for glass fiber reinforced, and high-temperature plastics as well as complex component geometries. However, various degradation phenomena can occur during the heating process used for economic reasons, due to the presence of oxygen in the air and to the high gas temperatures. In addition, the current patent situation suggests that welding with an oxidizing gas is not permissible depending on the material. On the other hand, however, there is experience from extrusion welding, with which long-term resistant weld seams can be produced using air. Investigations have shown that the same weld seam properties can be achieved with polypropylene using either air or nitrogen as the process gas. Experimental investigations have now been carried out on the suitability of different gases with regard to the weld seam quality when welding polyamides, which are generally regarded as more prone to oxidation. The results show that weld strengths are higher when nitrogen is used as process gas. However, equal weld strengths can be achieved with air and nitrogen when the material contains heat stabilizers.}}, author = {{Bialaschik, Max and Schöppner, Volker and Albrecht, Mirko and Gehde, Michael}}, issn = {{0043-2288}}, journal = {{Welding in the World}}, pages = {{1161--1169}}, title = {{{Influence of material degradation on weld seam quality in hot gas butt welding of polyamides}}}, doi = {{10.1007/s40194-021-01108-0}}, year = {{2021}}, } @article{24555, author = {{Moritzer, Elmar and Elsner, Christian Lennart and Schumacher, Christian}}, issn = {{0272-8397}}, journal = {{Polymer Composites}}, number = {{11}}, pages = {{6065--6079}}, title = {{{Investigation of Metal‐Polymer Composites Manufactured by Fused Deposition Modeling with Regard to Process Parameters}}}, doi = {{10.1002/pc.26285}}, volume = {{42}}, year = {{2021}}, } @misc{31744, author = {{Moritzer, Elmar and Hillemeyer, Johannes and Kramer, M. and Hopmann, C.}}, booktitle = {{Joining Plastics}}, issn = {{1864-3450}}, pages = {{94--103}}, title = {{{Designing of thermosetting plastic components for direct screwing - Auslegung von Duroplastbauteilen zur Direktverschraubung}}}, year = {{2021}}, } @misc{31740, author = {{Moritzer, Elmar and Richters, Maximilian}}, booktitle = {{Journal of Applied Polymer Science}}, number = {{38}}, title = {{{ Characterization of wood-filled thermoplastic polyurethanes for the injection molding process}}}, volume = {{138}}, year = {{2021}}, } @inproceedings{31760, author = {{Moritzer, Elmar and Krassmann, Dimitri and Brikmann, Johannes}}, booktitle = {{11.
