Optimization of 3D Printing Operation Parameters for Tensile Strength in PLA Based Sample

Öz

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

PLA Esaslı Numunelerde Çekme Dayanımı İçin 3D Baskı İşlem Parametrelerinin Optimizasyonu

Öz

Bu çalışmada, ergiyik yığma modelleme (FDM) esaslı 3D yazıcı kullanılarak üretilen PLA+ numunelerin mekanik özelliklerine baskı hızı, doluluk oranı ve tarama açısının etkileri detaylı olarak araştırılmıştır. Bu amaçla, Taguchi L₁₈ deney tasarımına göre 3D yazıcı ile standart çekme test numuneleri hazırlanmıştır. İşlem parametrelerinin (Baskı hızı, doluluk oranı ve tarama açısı) çekme dayanımı üzerindeki etkileri varyans analizi (ANOVA) ile belirlenmiştir. Ayrıca, Taguchi metodolojisi uygulanarak çekme dayanımı için işlem parametrelerinin optimizasyonu yapılmıştır. Sonuç olarak, çekme dayanımı üzerinde en etkin parametre doluluk oranı olurken, sırasıyla tarama açısı ve baskı hızı diğer önemli parametreler olarak tespit edilmiştir.
