Comparison of Strength, Surface Quality and Cost of Different Additive Manufacturing Methods

Abstract

Additive manufacturing is a manufacturing method that includes systems that produce using many different methods. The most widely used and accessible methods of additive manufacturing can be listed as Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS) and UV light assisted Stereolithography (SLA). Today, it is quite easy to produce thermoplastic products suitable for direct use in low quantities with these three methods. In addition, the production success of the parts produced in geometric difficulties also increases this demand. The most important problem is the lack of sufficient studies and information about the strength limits, surface quality and costs of the parts produced for additive manufacturing methods with such advantages. In this study, the comparison of three different production methods in terms of surface roughness, strength and cost is discussed in order to eliminate this deficiency in the literature. For this purpose, the tensile strength and surface roughness values of the samples produced using FDM, SLS and SLA methods were determined. In addition, cost analyzes were made depending on the production time of the produced samples. In the study, the lowest cost was obtained in the SLA material with a value of $ 0.19. Again, the lowest values were obtained for the samples produced from SLA material, with a production time of 17 minutes and a surface roughness of 1.96µm compared to other methods. However, when evaluated in terms of strength, the highest strength value was obtained as 57.67 N/mm2 in the FDM method.

Farklı Katkılı Üretim Yöntemlerinin Dayanım, Yüzey Kalitesi Ve Maliyetlerinin Karşılaştırılması

Abstract

Katmanlı imalat, birçok farklı yöntem kullanılarak üretim yapan sistemleri içeren bir imalat yöntemidir. Katmanlı imalat yöntemlerinden en yaygın kullanılan ve erişilebilir yöntemler Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS) ve UV ışık destekli Stereolitografi (SLA) olarak sıralanabilir. Günümüzde bu üç yöntem ile düşük miktarlarda doğrudan kullanıma uygun termoplastik ürünler üretmek oldukça kolaydır. Bunun yanında geometrik zorluklarda üretilen parçaların üretim başarısı da bu talebi arttırmaktadır. Bu kadar avantaja sahip katmanlı imalat yöntemleri için üretilen parça dayanım limitleri, yüzey kalitesi ve maliyetleri hakkında yeterli çalışma ve bilgi olmaması en önemli sorun olarak karşımıza çıkmaktadır. Bu çalışmada literatürdeki bu eksikliği gidermek amacıyla üç farklı üretim yöntemi yüzey pürüzlülüğü, mukavemet ve maliyet açısından karşılaştırılması ele alınmıştır. Bu amaçla FDM, SLS ve SLA yöntemleri kullanılarak üretilen numunelerin çekme dayanımları, yüzey pürüzlülük değerleri belirlenmiştir. Ayrıca üretilen numunelerin üretim süresine bağlı olarak maliyet analizleri yapılmıştır. Çalışmada en düşük maliyet 0.19 $ değer ile SLA malzemede elde edilmiştir. Yine SLA malzemeden üretilen numuneler için 17 dakika üretim süresi ve 1.96µm yüzey pürüzlülük değerleri diğer yöntemlere nazaran en düşük değerler elde edilmiştir. Ancak dayanım açısından değerlendiğinde en yüksek dayanım değeri FDM yönteminde 57.67 N/mm2 olarak elde edilmiştir.
