A STUDY ON THE MECHANICAL PROPERTIES OF PLA+ SAMPLES MANUFACTURED USING 3D PRINTING WITH DIFFERENT RASTER ANGLES

Abstract

In this study, the mechanical properties of PLA+ samples produced with different raster angles (0°, 90°, 0°/90°, 45° and ±45°) were investigated. Tensile tests were performed to determine the mechanical properties according to ASTM D-638 standard. The effects of raster angle on mechanical properties such as maximum force, elongation, toughness, modulus of elasticity, and ultimate tensile strength were analyzed. The results show that the raster angle significantly affects the mechanical behavior of PLA+ specimens. The highest maximum force and ultimate tensile strength were observed at 90°. In contrast, the lowest mechanical values were recorded at 0°, indicating a decrease in strength in this configuration. The ±45° raster angle exhibited the highest elongation and toughness, indicating greater ductility and energy absorption capacity. The modulus of elasticity showed relatively small differences between the different raster angles, with the highest value recorded at 90°. These findings highlight the critical role of raster angle selection in optimizing the mechanical performance of PLA+ components and provide valuable insights for additive manufacturing applications.

Bu çalışmada, farklı yazdırma açıları (0°, 90°, 0°/90°, 45° ve ±45°) ile üretilen PLA+ numunelerinin mekanik özellikleri incelenmiştir. Mekanik özellikleri belirlemek için ASTM D-638 standardına uygun olarak çekme testleri gerçekleştirilmiştir. Yazdırma açısının maksimum kuvvet, uzama, tokluk, elastikiyet modülü ve nihai çekme mukavemeti gibi mekanik özellikler üzerindeki etkileri analiz edilmiştir. Sonuçlar, yazdırma açısının PLA+ numunelerinin mekanik davranışını önemli ölçüde etkilediğini göstermektedir. En yüksek maksimum kuvvet ve nihai gerilme mukavemeti 90°'de gözlenmiştir. Buna karşılık, en düşük mekanik değerler 0°'de kaydedilmiştir, bu da bu konfigürasyonda mukavemette bir düşüş olduğunu göstermektedir. ±45° tarama açısı, daha fazla süneklik ve enerji emme kapasitesine işaret eden en yüksek uzama ve tokluğu sergilemiştir. Elastisite modülü, farklı yazdırma açıları arasında nispeten küçük farklılıklar göstermiş ve en yüksek değer 90°'de kaydedilmiştir. Bu bulgular, PLA+ bileşenlerinin mekanik performansını optimize etmede yazdırma açısı seçiminin kritik rolünü vurgulamakta ve eklemeli üretim uygulamaları için değerli bilgiler sağlamaktadır.
