Abstract

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

Abstract

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.
