Abstract

In this study, the dimensional accuracy and retraction performance of PET filament obtained through the recycling of PLA filament and PET water bottles were evaluated on test objects produced using a 3D FDM (Fused Deposition Modeling) printer. The aim of the study is to determine the usability and technical performance of recycled PET filament. Printing processes were carried out using different printing speeds with both PLA filament and recycled PET filament in the research. Measurements were taken for the dimensional accuracy of test objects produced at different speeds (30-40-50 mm/s) using a 3D printer. These measurements were conducted to assess the structural consistency of the filament and the dimensional precision of printed objects. Retraction performance was also evaluated by printing with both PLA filament and recycled PET filament at the same printing speeds. The results of the research can contribute to sustainable production processes by revealing how recycled PET filament performs in 3D FDM-type printers.

PLA ve GERİ DÖNÜŞTÜRÜLMÜŞ PET FİLAMENTLERİNİN 3D FDM BASKIDA BOYUTSAL DOĞRULUK ve GERİÇEKİLME PERFORMANSININ KARŞILAŞTIRILMASI

Abstract

Bu çalışmada, PLA filament ve PET su şişelerinin geri dönüştürülmesiyle elde edilen PET filamentin boyutsal doğruluğu ve geri çekilme performansı, 3D FDM (Fused Deposition Modeling) yazıcı kullanılarak üretilen test objeleri üzerinde değerlendirilmiştir. Çalışma, geri dönüştürülmüş PET filamentin kullanılabilirliğini ve teknik performansını belirlemeyi hedeflemektedir. Araştırmada farklı baskı hızları ile PLA filament ve geri dönüştürülmüş PET filament kullanılarak baskı işlemleri gerçekleştirilmiştir. 3 boyutlu yazıcı ile farklı hızlarda (30-40-50 mm/s) üretilen test objelerinin boyutsal doğruluğu için ölçümler yapılmıştır. Bu ölçümler, filamentin yapısal tutarlılığını ve basılan nesnelerin boyutsal hassasiyetini değerlendirmek amacıyla gerçekleştirilmiştir. Geri çekilme performansı için de aynı baskı hızları kullanılarak hem PLA filament hem de geri dönüştürülmüş PET filament ile baskılar alınmıştır. Araştırmanın sonuçları, geri dönüştürülmüş PET filamentin 3 boyutlu FDM tipi yazıcılarda nasıl performans gösterdiğini ortaya koyarak, sürdürülebilir üretim sürecine katkıda bulunabilir.
