The purpose of this research is to investigate the drying kinetics and determine of the suitable drying method of prina which is obtained after pressing of olives in olive oil factories and cannot be used efficiently in a certain sector. Drying experiments were performed at drying temperatures of 60 C, 70 C and 80 C at a fixed air velocity of 2 m/s using hot air dryer and with the microwave power of 90W, 360W, and 600W using microwave dryer. The prina layer thicknesses were selected as 7, 9 and 11 mm for both drying method. The minimum energy consumption values were measured as 42,0 Wh for 600 W power level and 7 mm layer thickness, as 10260 Wh for 7 mm layer thickness and 80 o C temperatures. It was found that energy consumption during hot air drying was more than that of microwave drying. As a result, the suitable dryer and thickness of layer were selected as microwave dryer and 7 mm, respectively. The results of statistical analyses showed that the most suitable model to define the drying behavior of prina samples were found as the Page model for microwave dryer and Wang & Singh model for hot air dryer.Also, penetration depth, the loss tangent value (tan ), dielectric constant of material ( ı ) and dielectric loss factor ( ıı ) of dried prina were calculated as 34.51cm, 0.1059, 75.65 and 8.01 at 2450MHz, respectively.

Acrylonitrile-butadiene-styrene test specimens were additively manufactured by fused deposition method to investigate the effects of infill pattern and density on wear rate, coefficient of friction, wear mechanisms, and microscopic wear characterization. The surface morphology of specimens was characterized using a scanning electron microscope. Under constant parameters of applied load, sliding speed, and sliding time, wear tests were carried out at room temperature. The study revealed that a grid pattern of high infill density and a honeycomb pattern of low infill density showed the lowest wear rate and lowest coefficient of friction compared to the rectilinear pattern. Infill pattern and density affected the wear rate behavior of specimens directly. Moreover, adhesion between additively manufactured layers along with surface texture affects the wear behavior and wear rate. Increasing infill density allowed poor cooling of previously built layers. Longer process time results in rough surfaces.

In this study, cylindrical, conical and hemispherical molds were used to form flat thermoplastic sheets which are 1.5 mm in thickness. The effect of plug assist on thickness distribution was investigated. The sheets were formed with and without plug assist. Then thickness distributions on thermoformed products were obtained for two experimental procedures by a digital caliper (Resolution: 0.01 mm). As a result, plug assist thermoforming provides more uniform thickness distributions than negative forming.
