EYM ile Üretilen YMK Yapılı Numunelerde Kenar Genişliğinin Basma Dayanımı Üzerine Etkisinin Araştırılması

Öz

Bu çalışmada, 3 boyutlu baskı (3D printing) kullanılarak üretilen farklı kenar genişliklerine sahip yüzey merkezli kübik YMK yapılı numunelerin basma dayanımı üzerindeki etkisi incelenmiştir. PLA malzemesi kullanılarak Eriyik Yığma Modellemesi (EYM) yöntemi ile numuneler üretilmiştir. Kenar genişliği arttıkça, maksimum basma yüklerinde ve basma dayanımlarında artışlar gözlenmiştir. En düşük yük 1,2 mm kenar genişliğinde 2849 N iken, en yüksek yük 2,4 mm kenar genişliğinde 6351 N olarak ölçülmüştür. Benzer şekilde, en düşük basma gerilimi 34,76 MPa ile 1,2 mm kenar genişliğinde, en yüksek basma gerilimi ise 40,15 MPa ile 2,4 mm kenar genişliğinde kaydedilmiştir. Kenar genişliğinin artmasıyla birlikte maksimum yük/kütle değeri %33,1 oranında artış göstermiştir. Sonuçlar, 3D baskı üretiminde kenar genişliğinin tasarım faktörü olarak önemini vurgularken, daha geniş kenar genişliklerinin ürünlerin mekanik dayanıklılığını artırabileceğini ve uygulama gereksinimlerine uygunluğunu sağlayabileceğini göstermiştir.

Investigation of the Effect of Edge Width on Compressive Strength of FCC Structured Specimens Produced with FDM

Öz

In this study, the effect of different edge widths of face-centered cubic (FCC) lattice structures, manufactured using the Fused Deposition Modeling (FDM) method with PLA material, on compressive strength was investigated using 3D printing technology. As the edge width increased, an increase in maximum compressive loads and compressive strengths was observed. The lowest load was measured as 2849 N for the sample with a 1,2 mm edge width, while the highest load was recorded as 6351 N for the sample with a 2,4 mm edge width. Similarly, the lowest compressive stress was 34,76 MPa for the 1,2 mm edge width, and the highest compressive stress was 40,15 MPa for the 2,4 mm edge width. An increase in edge width led to a 33,1% increase in the maximum load-to-mass ratio. The results emphasize the significance of edge width as a design parameter in 3D printing production, suggesting that wider edge widths could enhance the mechanical robustness of products and cater to application-specific requirements. This study highlights the importance of considering edge width during the design phase, and further investigations involving various sample designs or material selections could provide deeper insights into the influence of edge width on compressive strength.
