AB  - Katmanlı eriyik yığma modelleme (EYM) yöntemi, karmaşık parçaların üretiminde çeşitli avantajlar sunmaktadır. Bu teknolojinin başarısı yalnızca görsel kalite ile sınırlı olmayıp, aynı zamanda elde edilen parçaların mekanik özelliklerinin doğru bir şekilde belirlenmesine ve karakterize edilmesine de bağlıdır. Üç boyutlu yazıcılarla üretilen parçaların çekme, basma ve darbe dayanımı gibi mekanik özellikleri, üretim kalitesi ve son ürün performansı açısından kritik öneme sahiptir. Bu bağlamda, üretim sürecine ait parametrelerin mekanik davranış üzerindeki etkilerinin ayrıntılı biçimde incelenmesi gerekmektedir. Bu parametrelerden biri olan Z-Dikiş noktaları, katmanlar arası birleştirme stratejisini ifade etmekte olup parçanın bütünsel dayanımını doğrudan etkileyebilmektedir. Bu çalışmada, PLA malzemesi kullanılarak farklı Z-Dikiş parametreleriyle üretilen numuneler basma testine tabi tutulmuştur. Deneyler sonucunda, en düşük basma dayanımı 1.55 kN ile “Keskin Köşe – Gizli Dikiş” konfigürasyonunda, en yüksek dayanım ise 1.65 kN ile “En Kısa – Açık&Gizli Dikiş” konfigürasyonunda elde edilmiştir. Bu bulgular, Z-Dikiş noktalarının yerleşimi ve türünün, parça dayanımı üzerinde yaklaşık %10 oranında değişime neden olabildiğini ve bu parametrenin EYM ile üretimde dikkate değer bir etkiye sahip olduğunu ortaya koymaktadır.

N2  - Fused Deposition Modeling (FDM) offers various advantages in the production of complex parts. The success of this technology is not limited solely to visual quality, but also depends on the accurate determination and characterization of the mechanical properties of the produced parts. The mechanical properties of parts manufactured using three-dimensional (3D) printers—such as tensile, compressive, and impact strength—are critically important in terms of production quality and final product performance. In this context, it is necessary to examine in detail the effects of manufacturing process parameters on mechanical behavior. One of these parameters, the Z-Seam location, represents the interlayer bonding configuration and can directly affect the overall structural strength of the part. In this study, specimens produced with different Z-Seam parameters using PLA material were subjected to compression testing. As a result of the experiments, the lowest compressive strength was obtained in the “Sharp Corner – Hidden Seam” configuration with 1.55 kN, while the highest strength was achieved in the “Shortest – Open & Hidden Seam” configuration with 1.65 kN. These findings reveal that the location and type of Z-seam can lead to approximately a 10% variation in part strength, highlighting its significant influence as a process parameter in FDM.
