Bu çalışmada, 3 boyutlu (3B) yazıcılarda kullanılan poli(laktik asit) (PLA) filamentlerinin ve Eriyik Yığma Modelleme (EYM) esaslı 3B yazıcı kullanılarak üretilen PLA standart çekme numunelerinin mekanik ve baskı özelliklerinin nemli ortamlarda nasıl değiştiği incelenmiştir. Filamentler 25 °C sıcaklık ve %80 bağıl nemli ortama 5, 10, 15, 20 gün süreler ile maruz bırakılarak şartlandırılmış numuneler üretilmiştir. Bu filamentlere ve üretilen standart çekme numunelerine çekme testi uygulanmış, FTIR spektrometresi ile analizleri yapılmış ve kırılma yüzeylerinin taramalı elektron mikroskopu (SEM) görüntüleri alınmıştır. Şartlandırılmış filament ve standart çekme numunelerinin çekme dayanımları 20. günde sırası ile 3,7 MPa (%6,8) ve 3,6 MPa (%6,8) düştüğü fakat bekletme süresinin çekme dayanımları üzerinde önemli bir etkisinin olmadığı görülmüştür. Şartlandırılmış filamentten basılan standart çekme numunelerinin çekme dayanımları bekletme gün sayısı ile orantılı olarak azalmış ve çekme dayanımındaki en büyük düşüş 11,6 MPa (%29,5) değerinde 15. günde gerçekleşmiştir.

INVESTIGATION OF THE CHANGE IN THE MECHANICAL AND PRINT PROPERTIES OF THE POLY(LACTIC ACID) FILAMENTS USED IN 3D PRINTERS AS A RESULT OF EXPOSURE TO HUMID ENVIRONMENT

Öz

In this study, it was investigated how the mechanical and printing properties of poly(lactic acid) (PLA) filaments used in 3D printers and PLA standard tensile samples produced using 3D printer based on Fused Deposition Modeling (FDM) change in humid environments. Conditioned samples were produced by exposing the filaments to 25 °C temperature and 80% relative humidity for 5, 10, 15, 20 days. Tensile test was applied to these filaments and produced standard tensile samples, analyzed with FTIR spectrometer and scanning electron microscope (SEM) images of fracture surfaces were taken. The tensile strengths of the conditioned filament and standard tensile samples decreased by 3.7 MPa (6.8%) and 3.6 MPa (6.8%) on the 20th day, respectively, but the holding time did not have a significant effect on the tensile strengths. The tensile strength of standard tensile specimens printed from conditioned filament decreased in proportion to the number of days of holding, and the greatest decrease in tensile strength occurred on the 15th day at a value of 11.6 MPa (29.5%).
