Abstract

Additive manufacturing and the manufactured material technology are gaining increasing attention day by day. Among additive manufacturing methods, Fused Deposition Modeling (FDM) is the most commonly used production method. Factors such as the low cost of machines used in FDM, the ability to produce complex geometric structures in short production cycle times without the need for any cutting tools, and low waste material ratios are among the advantages offered by the method. Sandwich structures produced by this method attract researchers' interest due to their superior properties and functionality. Sandwich structures are defined as structures that are combined with a core material between inner and outer layers and are generally preferred for their lightweight and high strength. This study addresses the factors influencing the strength of sandwich structures, material selection, and layering methods. The most significant finding obtained from the research is that the strength properties exhibited separately by the polymers forming the sandwich structure can be enhanced when they come together to form the sandwich structure. The research aims to provide guidance for understanding the effect of production parameters on the strength properties of sandwich structures produced by Fused Deposition Modeling (FDM), optimizing the production process, and laying the groundwork for future applications.

FDM Yöntemi ile Üretilen Sandviç Yapılarda Üretim Parametrelerinin Mekanik Performans Üzerindeki Etkisi

Abstract

Eklemeli imalat ve üretilen malzeme teknolojisi her geçen gün daha fazla ilgi görmektedir. Eklemeli imalat yöntemleri içinde Eriyik Biriktirme Yöntemi (FDM) en yaygın kullanılan üretim metodudur. Eriyik Biriktirme Yönteminde kullanılan makinelerin maliyetinin ucuz olması, kompleks geometrili yapıların herhangi bir kesici takıma ihtiyaç duyulmadan kısa üretim döngü sürelerinde üretilebilmesi ve düşük artık malzeme oranları gibi unsurlar, yöntemin sunduğu avantajlar arasında gösterilmektedir. Bu yöntemle üretilen sandviç yapılar, üstün özellikleri ve fonksiyonelliği nedeni ile araştırmacıların ilgisini çekmektedir. Sandviç yapılar, iç ve dış katmanlar arasında bir çekirdek malzemesiyle birleştirilen yapılar olarak tanımlanır ve genellikle hafiflikleri ve yüksek mukavemetleri nedeniyle tercih edilirler. Bu çalışma, sandviç yapıların mukavemetini etkileyen faktörleri, malzeme seçimini, katmanlama yöntemlerini ele almaktadır. Araştırmadan elde edilen en önemli bulgu, sandviç yapıyı oluşturan polimerlerin ayrı ayrı sergiledikleri mukavemet özelliklerinin, sandviç yapıyı oluşturmak için bir araya geldiklerinde artırılabileceğidir. Yapılan araştırma, Eriyik Biriktirme Yöntemiyle üretilen sandviç yapılarda üretim parametrelerinin mukavemet özellikleri üzerindeki etkisini anlamak, üretim sürecini optimize etmek ve gelecekte yapılacak uygulamalar için bir temel oluşturmak için kılavuz sağlamayı amaçlamaktadır.
