Çalışmada eriyik yığma modelleme (FDM) yöntemi ile 3B yazıcı kullanarak üretilen PLA numunelerin mekanik özelliklerden olan çekme dayanımına işlem parametrelerinin etkisinin belirlenmesi amaçlanmıştır. Bu amaçla çalışmada işlem parametreleri olarak 2 farklı doluluk oranı (%20 ve %100), 2 farklı baskı hızı (100,130mm/sn), 2 farklı nozul sıcaklığı (180 ve 220°C) ve oval ve köşegen desen yapılarını içeren3 farklı desen çeşidi (Gyroid,Cross 3D ve Grid) seçilmiştir. Çalışmada, %20 doluluk oranına göre, %100 doluluk oranında daha yüksek çekme gerilmesi elde edilmiştir. %20 doluluk oranındaki numuneler kendi aralarında kıyaslandığında elde edilen en yüksek çekme gerilmesi değeri 2200C nozul sıcaklığında, 100 mm/s baskı hızında üretilen Grid desen çeşidinde 38.76 MPa olarak ölçülmüştür. Çalışmada %20 doluluk oranındaki numuneler için istatistik analiz yapılmıştır. Varyans analiz (ANOVA) yöntemi sonucu güven düzeyi %96 elde edilmiştir. Özgül dayanım açısından kıyaslama yapıldığında ise 5,893 MPa/gr özgül dayanıma sahip tam dolu parçaya en yakın desenin 5.458 MPa/gr değeri ile Cross 3D deseni olduğu belirlenmiştir.
The aim of this study was to investigate the effects of process parameters on tensile strength for PLA specimens produced by fused deposition modeling (FDM). For this purpose, two different density rates (20% and 100%), printing speeds (100 and 130 mm/s), and nozzle temperatures (180 and 220oC) with three different hatching patterns including elliptical and diagonal (Gyroid, Cross 3D ve Grid) were selected. In the study, higher tensile stress was obtained at a rate of 100%, compared to a 20% density rate. When the samples with a 20% density rate are compared among themselves, the highest tensile stress value obtained was measured as 38.76 MPa for the Grid-patterned specimen produced at a nozzle temperature of 2200C and printing speed of 100 mm/s. Statistical analysis was also done for specimens with a 20% density rate. As a result of the variance analysis (ANOVA) method, the confidence level was achieved as 96%. When comparing in terms of specific strength, it was determined that the closest pattern to the full-filled sample with a specific strength of 5,893 MPa/gr was Cross 3D-patterned sample with a value of 5.458 MPa/gr.
