Abstract

Eklemeli imalat (Eİ) yöntemleri son yıllarda oldukça popüler hale gelmiştir ve bu faydalı imalat yöntemine yönelik bilimsel çalışmaların sayısı her geçen gün artmıştır. Şimdiye kadar, çalışmaların çoğu, üç boyutlu (3B) basılmış numunelerin fiziksel ve mekanik özellikleri üzerine olmuştur. Bu yazıda, eklemeli olarak üretilen polilaktik asit (PLA) parçaların darbe özellikleri ayrıntılı olarak ele alınmıştır. Tüm numuneler, eriyik yığma modelleme yoluyla üretilmiştir. İmalattan sonra, önerilen tekniğin etkinliğini araştırmak için sertlik ve yüzey pürüzlülüğü ölçümleri yapılmıştır. PLA numunelerin darbe özelliklerini tespit etmek için Charpy v-çentik darbe testleri yapılmış ve çentik açısının etkisi incelenmiştir. İmalat parametrelerinde ise, dolgu yoğunluğu faktörü değiştirilmiş ve numunelerin darbe davranışları üzerindeki etkileri belirlenmiştir. Ayrıca, deformasyonun ana mekanizmasını daha iyi anlamak için test edilen PLA numuneleri üzerinde ayrıntılı bir şekilde mikro ve makro hasar analizleri yapılmıştır.

An Experimental Effort on Impact Properties of Polylactic Acid Samples Manufactured by Additive Manufacturing

Abstract

Additive manufacturing (AM) has been highly popular in recent years and the number of scientific efforts on this useful manufacturing way has increased day by day. Up to now, the majority of the studies accumulated on the physical and mechanical properties of the three-dimensional (3D) printed specimens. In this paper, the impact properties of the additively manufactured polylactic acid (PLA) parts were addressed in detail. All specimens were manufactured by way of fused deposition modeling (FDM). After the manufacturing, hardness and surface roughness measurements were carried out to probe the effectiveness of the offered FDM technique. In order to detect impact features of the PLA specimens, Charpy v-notch impact tests were conducted and the influence of the notch angle was examined. As for the manufacturing parameters, the factor of infill density was altered and its effects on the impact behaviors of the specimens were established. Furthermore, micro and macro damage analyses were performed elaboratively on tested PLA specimens to comprehend the main mechanism of deformation better.
