This study investigated the effects of FDM (Fused Deposition Modeling) process parameters on mechanical properties (tensile strength, elongation, and impact strength) of 3D (three-dimensional) printed PA12 (Polyamide12) samples using Taguchi method. In the experimental design (L8), four different layer thickness (0.1, 0.15, 0.2, 0.25 mm), extruder temperature (250 and 260°C), filling structure (Rectilinear and Full Honeycomb), and occupancy rate (25 and 50%) were determined. The tensile and impact strength test samples were printed with the FDM method. Tensile and impact strength of the test samples were carried out according to ISO 527 and ISO 180 test standards. The findings obtained from tests were analyzed and compared. As a result, the layer thickness is most effective factor for enhance the mechanical properties instead extruder temperature, occupancy rate, and filling structure. The optimum tensile strength of determined for process parameters (layer thickness, occupancy rates, filling structures and extruder temperature) were 0.25 mm, 50%, Rectilinear, and 250°C, respectively. The optimum impact strength of determined for process parameters (layer thickness, occupancy rates, extruder temperature, and filling structures) were 0.25 mm, 50%, 250°C, and Rectilinear, respectively. PA12 filament material can be used to printing for sleeve bearing due to their mechanical properties. It can be used in the production of many machine parts and components due to its tensile strength, impact strength resistance and damping properties.
In this study, it was realized to determine effects of Fused Deposition Modeling (FDM) process parameters on mechanical characteristics with Taguchi optimization method. Three different FDM process parameters used for modified Polylactic Acid (PLA+) filament material; filling structures (Rectilinear, Triangular, and Full Honeycomb), occupancy rates (10, 30, and 50 %) and table orientation (0, 60, and -45°) was specified as variable parameters for experiments.Other parameters kept fixed for each tensile and izod impact test samples were printed according to the ISO 527 -Type IV and ISO 180-Type I standards. The results found tensile strength values and izod impact values directly proportionate with occupancy rate. The difference between the estimation model and the results of experiments did not exceed the maximum value of 1.8 %. Thus, using the equations derived from this optimization, printing parameters can be determined for the desired tensile strength and izod impact values. By improving the material properties using modified PLA+ filament material as observed in the results, it will be possible to provide support for researchers, design engineers and manufacturer to optimize raw-material usage and margin.
The main objective of this study is to analyze of the effect of fused deposition modelling (FDM) printing process parameters on the mechanical properties, printing times and production costs of samples printed with Power Acrylonitrile Butadiene Styrene (PowerABS) filament using a three-dimensional (3D) printer. This study is primarily focused on the effects of the mechanical properties of 3D samples subjected to the influence of three factors; layer thickness (0.15, 0.2, and 0.25 mm), raster angle (15, 45, and 75 0 ), table orientation (flat, horizontal, and vertical). For the experiment study, analytical methods such as regression analysis, variance analysis (ANOVA), Signal / Noise (S / N) ratio were used to determine the effect of FDM printing parameters on the mechanical properties with Taguchi optimization method. The results showed that 45° raster angle the highest mechanical properties at each individual layer when compared to 15° and 75°. The results also found tensile strength to directly proportionate to layer thickness. As observed in the results, by improving the material properties, it will be possible to provide support for mechanical engineers and designers to reduce printing time, filament material use and printing costs.
Particularly in the fruit juice industry, the remaining peels and pulp parts are not available for human consumption after the juices are used. It is possible to evaluate these wastes by adding them to poultry feeds. A number of studies have been conducted by researchers on the nutritional value of many fruit wastes and on the performance of poultry. Natural antioxidant content has been reported to have a positive effect on growth, microbial and immunological parameters when high fruit peels are used as feed additive in poultry feeding.
Thirty-six Merino-Kıvırcık crossbred male lambs were utilized to evaluate the influence of two levels of dried stoned olive pomace. Lambs were blocked by initial body weights (BW, 20.4 kg) and randomly distributed into three groups. While one group received commercial concentrates without olive pomace, the second and third groups received an experimental diet containing 10% olive pomace and 20% olive pomace, respectively. They were fed for 49 days. The animals' BW and feed consumption were recorded weekly and biweekly, respectively. The lambs were slaughtered at the end of the trial. The carcass cut weights were recorded and a sample of LD muscle was collected for fat content and composition. Overall, there were no differences in slaughter characteristics, carcass measurements, or cut weights among the treatments (P > 0.05). The fatty acids (FAs) profile of LD muscle showed that 20% olive pomace fed animals had lower pentadecanoic and erucic acids, while they had higher oleic acid content (P < 0.05). This represents a favorable change in regard to human dietary guidelines. Total saturated, monounsaturated, and polyunsaturated FAs were not affected by treatments. There were minor differences in organoleptic properties among the treatments (P > 0.05). Meat rich in oleic acid fared best with panelists, which was found in the 20% olive pomace fed lambs.
