Examination of 3D printing parameters using machine learning

Öz

In this study, the mechanical properties of tensile samples produced in 3D printers with the fused deposition method (FDM) were investigated. Here, the parameters such as layer (filament) thickness, infill type and support angle in the FDM method were examined. The production was produced with Up-right and edge directions. As a result of the experiments, the best layer thickness in terms of tensile strength was 0.09 mm, and the infill type was full infill type, while different results were obtained in the support angle. According to the variance analysis (ANOVA) values, it was observed that the layer thickness and infill type were quite effective on the tensile strength, but the support angle was at a negligible level. In the second stage, the results were estimated with xgboost and catboost from the machine learning algorithms and linear regression models. The most effective algorithm on the examined mechanical properties was determined as the catboost algorithm.

Makine öğrenmesi ile 3D yazdırma parametrelerinin incelenmesi

Öz

Bu çalışmada ergiyik yığma metodu (Fused Deposition Modelleme/FDM) yöntemi ile 3D yazıcılarda üretilen çekme numunelerinin mekanik özellikleri incelendi. Burada FDM yöntemindeki katman (filament) kalınlığı, dolgu tipi ve support açısı gibi parametreler incelendi. Üretim Up-right ve edge yönleri ve her bir yön için Taguchi L25 deney tasarımıyla üretildi. Deneyler neticesinde çekme mukavemeti açısından en iyi katman kalınlığı 0,09 mm, dolgu tipi olarak full dolgu tipi olurken support açısında farklı sonuçlar elde edildi. Varyans analizi (ANOVA) değerlerine göre parametrelerden katman kalınlığı ve dolgu tipinin çekme mukavemeti üzerinde oldukça etkili olduğu ancak support açısının göz ardı edilebilecek düzeyde olduğu gözlemlendi. İkinci aşamada sonuçlar makine öğrenmesi algoritmalarından xgboost ve catboost ile ve linear regression ile tahmin modelleri yapıldı. İncelenen mekanik özellikler üzerinde en etkin algoritma catboost algoritması olarak belirlendi.
