Impact of Raster Angle and Infill Density on Dimensional Accuracy in 3D Printing: A Study on ABS Material

Abstract

With the advancement of technology, the use and implementation of modern 3D printing systems have become increasingly widespread. Today, 3D printers are actively utilized in various industries including engineering, construction, manufacturing, and architecture. This study investigates the dimensional accuracy of test specimens produced using ABS filament at different raster angles and infill densities in the vertical direction. Test specimens were designed in SolidWorks, and printed using the Creality K1 Max 3D printer after G-code generation in the Creality Print 6.0 software. The same filament type was used to print samples at five different raster angles (0°, 30°, 45°, 60°, and 90°) and three infill densities (15%, 50%, and 80%). For each raster angle, five specimens were produced. Dimensional accuracy was evaluated based on length × width × thickness measurements (Mitutoyo caliper), mass (precision scale), and surface quality (Nikon T105 microscope). Estimated pre-print weights from the slicing software were also compared to the actual printed weights. The results showed that both raster angle and infill density significantly influence the dimensional accuracy of printed parts. In particular, samples printed at 90° showed the closest dimensions to the original design, while 45° samples were found to be most accurate in terms of predicted weight.

3B Baskı Sürecinde Tarama Açısı ve Doluluk Oranının Boyutsal Uygunluğa Etkisi: ABS Malzeme Üzerine Bir Çalışma

Öz

Teknolojinin gelişmesiyle birlikte günümüz 3 boyutlu yazıcı sistemlerinin kullanımı ve uygulanması yaygınlaşmıştır. 3 boyutlu yazıcılar mühendislik, inşaat, mimari, yapı endüstrisi gibi çeşitli sektörlerde aktif olarak kullanılmaktadır. Bu çalışmada 3 boyutlu yazıcı teknolojisinden yararlanılarak ABS tip filamentten üretilen örnek numunelerin farklı açılarda yapılan baskılarında boyutsal doğruluğu araştırılmıştır. Çalışmada aynı filament tipinden üç farklı doygunluk (%15,50,80) ve beş farklı baskı açısından (0°,30°,45°,60°,90°) yararlanılarak SolidWorkds tasarım programında tasarlanan örnekler, Creality 6.0 programıyla G kodlaması yapıldıktan sonra, Creality K1 Max 3 boyutlu yazıcı ile basılmıştır. Çalışmada her farklı açı için 5 er numune basılmış ve doğrusal doğruluğu uzunluk x genişlik x kalınlık (Mitutuya Kumpas), ağırlık (Hassas terazi) ve görsel yüzey özelliklerine (Nikon T105 mikrodskop) bakılarak değerlendirilmiştir. Değerlendirmede baskıdan önceki boyutlar, dilimleme programındaki tahmini ağırlık karşılaştırılması da yapılarak nihai sonuçlara ulaşılmıştır. Ulaşılan sonuçlara göre; baskı açısının boyutsal doğruluk üzerinde etkili olduğu, bu doğruluğa açılar haricinde baskı doygunluğu ile doğrudan etkisi olduğu belirlenmiştir.
