Farklı Doldurma Şekillerinin Üç Boyutlu Yazıcılarda Üretilen Ürünlerin Mukavemetine Etkisi

Öz

Bu çalışmada, farklı doldurma şekillerinin Ergiyik
Depolayarak Modelleme (Fused Deposition Modelling - FDM) yöntemi ile imal
edilen ürünlerin mukavemetine etkisi deneysel olarak incelenmiştir. Çalışmada filament
malzeme olarak PET-G (Polyethylene Terephthalate Glycol) kullanılmış ve farklı
doldurma şekillerinde (Rectilinear, Grid, Triangular, Wiggle, Fast honeycomb, Full
honeycomb), doluluk oranı (%30), işleme hızı (4200 mm/dak), nozul çapı (0,40
mm), nozul sıcaklığı (230 ºC), katman kalınlığı (0,20 mm) olmak üzere ISO 527-2
standardına uygun ürünler imal edilmiştir. Bu numunelerin çekme mukavemetlerini
incelemek için çekme testleri gerçekleştirilmiş ve testlerden elde edilen
sonuçlar karşılaştırılmıştır. Sonuçlar yazdırma şekillerinin ürün mukavemeti
üzerinde önemli etkisi olduğunu göstermiştir. Rectilinear doldurma şeklinde
imal edilen ürünlerde elde edilen mukavemet değerleri diğer doldurma
şekillerine göre yaklaşık % 15 daha yüksek çıkmıştır. Ayrıca, Full honeycomb
doldurma şeklinin diğer doldurma şekillerine göre daha fazla uzama gösterdiği
görülmüştür.
