## 1 Introduction
Three printing orientations with raster directions were investigated to observe the changes in the mechanical properties of the specimens. They found that the specimens printed on a plane with a raster horizontal direction show the highest ultimate strength and elongation and behave as ductile materials. In contrast, the specimens printed in raster vertical directions almost act as brittle materials. The results show that the specimens with different print orientations yield anisotropic behavior. This behavior is also indicated in the prediction of fatigue behavior estimated from the tensile results. The mechanical properties of 316L stainless steel parts manufactured using BMD were studied by [27]. Print parameters, which varied in their study, included build orientation, chamber temperature, and infill pattern. Build orientations consist of horizontal and vertical directions. Chamber temperatures were investigated at room temperature and at 50 \({}^{\circ}\)C. The infill patterns include a concentric pattern filled by wall thicknesses and a \(\pm 45^{\circ}\) raster pattern layered by top/bottom thicknesses. They concluded that the specimens built in the horizontal direction have higher ultimate strength than those in the vertical direction. The \(\pm 45^{\circ}\) raster pattern presented a slightly higher ultimate strength rating than the concentric pattern. In addition to the studies on the mechanical properties, [PERSON] et al. [29] reported on the energy efficiency and lifecycle of AM parts using the BMD. Many metal materials can be used as raw materials in MAM technologies, especially stainless steel. In BMD technology, 17-4 PH and 316L are basic print materials for AM parts. 17-4 PH stainless steel is characterized by its strength, hardness, and corrosion resistance, making it suitable for various applications, e.g., tooling, molds, and production parts. 316 Lstainless steel is a fully austenitic stainless steel, characterized by its corrosion resistance and performance at high and low temperatures. It is often used in chemical processing, saltwater environments, and household or industrial fixtures. Consequently, 17-4 PH and 316L are commonly used in many sectors, and their mechanical behavior has been widely investigated [13; 14; 26; 27; 28; 30; 31]. In reality, materials are usually loaded with a cyclic load, leading to failure due to fatigue. Due to its ductility, 316L stainless steel is often used to carry a cyclic load. The mechanical properties of 316L stainless steel under cyclic loading have been studied by a group of researchers [32; 33; 34; 35; 36; 37]. Some of them investigated the fatigue behavior of 316L stainless steel fabricated by MAM technologies. The fatigue behavior of MAM parts made from other materials was also explored [38; 39; 40; 41; 42]. Since the BMD is a new and attractive technique for MAM technologies, the mechanical properties of productions fabricated using the BMD have not been studied sufficiently, especially on fatigue performance. This study intends to investigate the mechanical properties of MAM parts, i.e., 316L and 17-4 PH stainless steel, fabricated using the BMD technique. The considered mechanical properties of the metal parts are elastic modulus, yield strength, ultimate strength, and fatigue limit. The metal specimens with different infill densities ranging from approximately 50% to 75% of the relative density are investigated. All samples are designed for a tensile test according to the ASTM E8/E8M standard [43]. Some mechanical properties obtained from the tensile test are validated by analytical results from the literature [17; 19]. Additionally, according to the ASTM E466 standard [44], the fatigue test is performed to study the fatigue life of the metal parts. The ratio between the weights of each infill specimen and the full-solid counterpart is considered as the weight density of the specimens with different infill densities.
