Fused deposition modeling (FDM) is a widely used additive manufacturing technique for producing polymeric parts. While most commonly used FDM filaments are PLA and ABS, nylon is a widely used thermoplastic polymer in industry. This study investigated the mechanical properties of FDM-produced specimens made of nylon and quantified the effect of process parameters such as raster orientation and nozzle temperature on the mechanical properties. As the nozzle temperature increases, specimens become stronger with higher elongations at the break. This is mainly due to the improved fusion between the layers, provided by an expansion of the heat-affected zone. On the other hand, specimens with diagonal raster orientation exhibit higher elongations than those with perpendicular and parallel raster. The findings also emphasize the synergistic effects between nozzle temperature and printing orientation, showing that optimization should consider the two parameters together. Overall, FDM can produce strong nylon parts with adequate ductility suitable for load-bearing applications. However, achieving such results requires a detailed optimization of process parameters.

Tunable mechanical properties of thermoplastic foams produced by additive manufacturing Alduais, Abdullah; Özerinç, Sezer (2023-3-01) Fused deposition modeling (FDM) is a versatile additive manufacturing technique for producing polymeric parts. Incorporating a foaming agent into the filament material enables the FDM-printing of thermoplastic foams, which opens up new possibilities for achieving desired mechanical property combinations. This study explored the process-property design space of FDM-printed polylactic acid (PLA) foams. Tensile and compression specimens were produced at a wide range of printing parameters using a commercial th...
Mechanical behaviour of polymeric lattice structures produced by additive manufacturing Kalaycıoğlu, Şükrü Güray; Özerinç, Sezer; Department of Mechanical Engineering (2022-11) Additive manufacturing (AM) is a manufacturing method based on the layer-by-layer deposition of the desired geometry. Polymer AM provides means to produce compliant polymeric structures for impact-absorbing applications. The recent introduction of foaming elastomeric filaments opened a new design space for achieving optimized impact absorbance performance. This thesis investigates this route through the mechanical testing of solid and cellular polymer foam structures produced by additive manufacturing. The...
Improving the ductility of polylactic acid parts produced by fused deposition modeling through polyhydroxyalkanoate additions Kaygusuz, Burçin; Özerinç, Sezer (2019-11-01) Polylactic acid (PLA) is one of the most commonly used materials for fused deposition modeling (FDM) due to its low cost, biocompatibility, and desirable printing characteristics. However, its low ductility is a major disadvantage for engineering applications where high damage tolerance is needed. This study investigates the feasibility of polyhydroxyalkanoate (PHA) additions to PLA for improving the ductility of parts produced by FDM. Thermal and mechanical behavior of PLA/PHA specimens containing 12 wt % ...
Design of a high precision hybrid AM machine Yılmaz, Yunus Emre; Dölen, Melik; Department of Mechanical Engineering (2019) Precision requirements in fused deposition modelling (FDM) processes have been increasing in recent years, especially after recognizing the potential of FDM process to produce complex and functional components. In order to increase precision of FDM process, 6-axis hybrid manufacturing system, which can carry out additive- and subtractive manufacturing processes in one manufacturing system platform, is designed. During design, kinematic analysis of the machine is done, axial- and angular errors are estimated...
Simulator of an additive and subtractive type of hybrid manufacturing system Dilberoğlu, Mecid Uğur; Yaman, Ulaş; Dölen, Melik (2019-06-24) Additive Manufacturing (AM) facilitates the production of intricate objects despite its weakness in attainable part quality and fabrication speed compared to the conventional manufacturing methods. To alleviate the problems arising as a natural outcome of AM methods, hybrid technologies become viable options by employing concurrent manufacturing procedures, e.g. synergetic additive and subtractive manufacturing (SM) actions. Hybrid workstations have recently opened up new dimensions to 3D-printing industry,...
