Abstract

Thermoplastic polymer have been used in 3D printing technologies since the objects produced via 3D methods by using thermoplastic materials can be recycled and reformed easly. In order to use a thermoplastic material in the 3D technologies, the thermplastic polymers are spun into fiber structures and then 3D objects are produced from these fibers. In this regard, low density polyethylene (LDPE) and high density polyethylene (HDPE) were melt spun into fiber with various construction including neat, blend and bicomponent forms. Chemical, microstructural, thermal and mechanical properties of the produced fibers were investigated. 3D printable properties of the prepared fibers were observed by using them in the 3D printer. It was observed that bicomponent LDPE/HDPE fibers were the most suitable fiber to produced 3D sample in the lab scale 3D printer. 3D honeycomb structure was produced from this fiber and its compression strength property was investigated by comparing the same size of the PLA honeycomb structure. Compression strength test result of the honeycomb sample produced from LDPE/HDPE bicomponent fiber was close to compression strength test result of the PLA honeycomb sample. The results revelaled that LDPE/HDPE bicomponent fibers could be an alternative to PLA fiber in 3D printing technologies.

Özet

Termoplastik polimerlerin geridönüşümü ve eritilerek yeniden şekillendirilebilmesi kolay olduğu için üç boyutlu (3B)yazıcılarda kullanımı son yıllarda yaygınlaşmıştır. Termoplastik polimerik yapılar önce eriyikten çekim yöntemi ile istenen özelliklerdefilament formuna getirilip daha sonra bu filamentlerin 3B yazıcılarda kullanılmasıyla 3B yapılar elde edilmektedir. Bu çalışmada,termoplastik polimerler olan düşük yoğunluklu polietilen (LDPE) ve yüksek yoğunluklu polietilen (HDPE)’den farklı oranlarda saf,karışım ve bikomponent filamentler eriyikten çekim yöntemi ile üretilmiştir. Üretilen filamentlerin kimyasal, mikroyapısal, termal vemekanik özellikleri incelenmiştir. Filamentlerin 3B yazıcılarda kullanılabilirliğini gözlemlemek için üretilen filamentlerden 3B yazıcıdanumuneler üretilmiştir. Üretilen filamentlerden bikomponent yapıda olan LDPE/HDPE filamentinin kullanılan 3B yazıcı için en uygunfilament olduğu tespit edilmiştir. Bu filamentten 3B balpeteği yapı üretilip, yapının basma mukavemeti özelliği PLA filamentindenüretilen balpeteği yapı ile kıyaslanması suretiyle incelenmiştir. LDPE/HDPE bikomponent filamentten üretilen balpeteği yapının basmamukavemeti özelliği piyasada yaygın kullanılan PLA’nın değerlerine yakın olduğu gözlemlenmiştir ve PLA gibi termoplastikkarakterde olan bu filament yapısının PLA’ya alternatif olarak 3B yazıcılarda kullanılabileceği sonucuna varılmıştır.
