3B Yazıcılarda Kullanılan Farklı Tip Ekstüderlerin ANSYS Programı ile Termal Analizlerinin Gerçekleştirilmesi

Bu çalışmanın amacı, 3B yazıcılarda ticari olarak kullanılan J-Head ekstrüder ve Volcano ekstrüderlerin ANSYS sonlu elemanlar yazılımı ile modellerin kararlı hal termal analizlerini gerçekleştirmek, modellerin eksiklikleri ve birbirlerine göre üstünlüklerini belirlemektir. Modellerin tasarımsal farklılıkları ve geometrik özellikleri farklı termal davranışlar göstermesine neden olmaktadır. Başlangıç koşulları ve sınır şartları her iki model için aynı olması sağlanmış, böylelikle diğer değişkenlerin sabit olmasına bağlı olarak tasarımların termal analizleri ön plana çıkarılmıştır. Termal analiz ile modellerin tasarımlarının baskı malzemesinin füzyonu üzerindeki etkileri incelenmiştir. Analiz sonuçları, modellerin avantaj ve dezavantajlarını ortaya koymuş ve gelecekte yapılabilecek yeni tasarımlar için bilgi kaynağı oluşturmuştur.

Performing Thermal Analysis of Different Types of Extruders Used in 3D Printers with ANSYS Program

The aim of this study is to perform steady-state thermal analysis of the models of J-Head extruders and Volcano extruders used commercially in 3D printers with ANSYS finite element software and to determine the shortcomings of the models and their advantages over each other. The design differences and geometric features of the models cause them to exhibit different thermal behaviours. The initial conditions and boundary conditions were ensured to be the same for both models, thus the thermal analysis of the designs highlighted depending on the other variables being constant. The effects of the designs of the models on the fusion of the printing material were examined by thermal analysis. The results of the analysis revealed the advantages and disadvantages of the models and created a source of information for new designs that can be made in the future.
