Deneysel ve Sonlu Elemanlar Yöntemleri 3D Baskılı Malzemenin Çeşitli Gözeneklilik ile Öngörülmesi

Bu makalede, belirli geometriye sahip modellerin elastik modülü ve akma dayanımı değerlendirilmiştir. Bunun için deneysel ve teorik çalışmalar yapılmıştır. Üretilen modeller, bir pres altında sıkıştırma testine tabi tutulmuş ve ANSYS programında ise analiz (FEA) edilmiştir. Elde edilen sonuçlar, mukavemet, süneklik, ve kilo kaybı açısından en uygun gözeneklilik yüzdesinin belirlenmesinde kullanılmıştır. Sonuçlar n kuvveti, süneklik ve ağırlık azaltmayı koruyan uygun gözeneklilik yüzdesini değerlendirmek için kullanılmıştır. Dayanıklılık, elastik ve plastik modül verimi, porozitenin artmasıyla azalmıştır. En önemli değişiklik elastik modülünde ortaya çıkmıştır.

Experimental and Finite Element Methods prediction of 3D printed material mechanical properties with various porosity

In this article, elastic modulus and yield strength of models with specific geometry are evaluated. Experimental and theoreticalstudies were carried out. Produced models were subjected to compression test under one press and analysis (FEA) in ANSYSprogram. The results were used to determine the most suitable porosity in terms of strength, ductility, and weight loss. The resultswere used to assess the percentage of proper porosity that protects the force, ductility and weight reduction. Durability, elastic andplastic module yield decreased with increasing porosity. The most important change occurred in the elastic modulus.
