In this study, the mechanical properties of PLA+ samples produced byusing fused deposition method (FDM) based 3D printer were investigated indetail for the effects of printing speed, infill rate and raster angle. Forthis purpose, standard tensile test specimens were prepared with a 3D printeraccording to Taguchi L18 experimental design. The effects on thetensile strength of the process parameters (printing speed, infill rate andraster angle) were determined by analysis of variance (ANOVA). In addition, theprocess parameters for the tensile strength were optimized by applying theTaguchi methodology. Consequently, while the most effective parameter on thetensile strength was the infill rate, the raster angle and the printing speedwere determined as other important parameters, respectively.

Bu çalışmada, ergiyik yığmamodelleme (FDM) esaslı 3D yazıcı kullanılarak üretilen PLA+ numunelerin mekaniközelliklerine baskı hızı, doluluk oranı ve tarama açısının etkileri detaylıolarak araştırılmıştır. Bu amaçla, Taguchi L18 deney tasarımına göre3D yazıcı ile standart çekme test numuneleri hazırlanmıştır. İşlemparametrelerinin (Baskı hızı, doluluk oranı ve tarama açısı) çekme dayanımıüzerindeki etkileri varyans analizi (ANOVA) ile belirlenmiştir. Ayrıca, Taguchimetodolojisi uygulanarak çekme dayanımı için işlem parametrelerininoptimizasyonu yapılmıştır. Sonuç olarak, çekme dayanımı üzerinde en etkinparametre doluluk oranı olurken, sırasıyla tarama açısı ve baskı hızı diğerönemli parametreler olarak tespit edilmiştir.
