Bu çalışmada, 3B (üç boyutlu) baskı teknolojisinde filaman malzemesi olarak en yaygın kullanılan PLA (poli laktik asit), ABS (akrilonitril bütadien stiren) ve PETG (polietilen tereftalat glikol) malzemelerinin çekme, termo-mekanik ve adhezif aşınma özelliklerinin karşılaştırmalı olarak incelenmesi amaçlanmıştır. Baskı prosesi, son kullanıcıların en çok tercih ettiği imalat parametreleri ve dilimleme yazılımının varsayılan olarak sunduğu seçenekler dikkate alınarak gerçekleştirilmiştir. Mekanik testler, malzemelerin camsı geçiş sıcaklıkları dikkate alınarak 25, 35 ve 45 °C olmak üzere üç farklı sıcaklıkta uygulanmıştır. Tribolojik özelliklerin belirlenmesi için numunelerin hem alt hem de üst yüzeyleri standart pin-on disk test cihazı kullanılarak adhezif aşınmaya maruz bırakılmıştır. Çekme testleri boyunca mekanik özelliklerin sıcaklıkla değişimi açısından en hassas malzemenin PLA, en kararlı malzemenin ise ABS olduğu gözlenmiştir. Numunelere DMTA (Dinamik Mekanik Termal Analiz) testleri uygulanarak depo modülü değerlerinin sıcaklıkla değişimi de incelenmiştir.

Comparative Investigation of Mechanical, Tribological and Thermo-Mechanical Properties of Commonly Used 3D Printing Materials

Öz

In this study, it is aimed to comparatively examine tensile, thermomechanical, and adhesive wear properties of PLA (poly lactic acid), ABS (acrylonitrile butadiene styrene) and PETG (polyethylene terephthalate glycol) materials, which are the most widely used filament materials in 3D (three dimensional) printing technology. The printing process was carried out by considering the mostly preferred manufacturing parameters by the end users and the options offered by the slicing software by default. Mechanical tests were performed at three different temperatures, 25, 35 and 45 °C, according to the glass transition temperatures of the materials. Determination of tribological properties, both bottom and upper surfaces of the test samples were exposed to adhesive wear by using standard pin-on disc tester. During the tensile tests, it was observed that the most sensitive material in terms of the alteration of mechanical properties with temperature was PLA, and the most stable material was ABS. It was determined that there was a significant difference in wear volume for all tested materials, depending on whether the abraded surface was top or bottom. The variation of storage modulus values with temperature was also investigated by applying DMTA (Dynamic mechanic thermal analysis) tests to the samples.
