“…Al-Si alloys are widely used in automotive and aerospace industries and constitute approximately 80-90% of the worldwide produced cast Al products [5]. Magnesium is commonly added to enhance strength, and conventionally cast Al-Si-Mg alloys obtain their increased strength from semi-coherent Mg 2 Si precipitates which form during aging and act as barriers to dislocation movement under stress [6].…”

“…Moreover, the previous studies demonstrated that the SLM-fabricated parts had sufficient mechanical qualities for clinical usage [72]. For instance, the research findings indicate the material properties of Co-Cr produced by SLM has greater tensile strength and fracture toughness characteristics compared to investment casting [74,75]. Moreover, for medical applications, the corrosion resistance data for manufactured parts are crucial.…”

Thin-walled structures are a significant and growing portion of engineering construction, with a wide range of applications, including storage vessels, industrial buildings, warehouses, aircraft, automobiles, bridges, ships, and oil rigs. Thin-walled components with minimum thickness without compromising strength and other quality characteristics are the desire of modern industry. Reducing wall thickness not only aids in lowering the cost of production. It also improves the effectiveness of engineering systems, resulting in lower fuel consumption and lower emissions of hazardous gases to the environment. Nowadays, even though thin-walled parts are demanded, the constraints of the production process, quality, and reliability are the concerns of current research and development. The ability to produce parts with intricate geometries and tight dimensional tolerances are important criteria for advanced manufacturing processes. In the early days of society, investment casting was used to produce jewelry, weapons, and statues. In modern industry, investment casting is still used to produce thin-walled and intricate parts such as turbine blades. The current advancements in SLM, which has the capacity to produce thin-walled and intricate parts, have recently attracted attention due to several benefits, such as the supreme degree of design freedom and the viability of tool-free production directly from CAD data. However, the current technological applications of SLM and investment casting are crucial for producing parts at the desired quality and reliability. This review article focuses on comparative studies of SLM and investment casting at the current technology level. The basis of comparison via systematic approach is mechanical characterization; quality in terms of porosity, microstructure, surface roughness and dimensional accuracy; and residual stress. Therefore, the latest open scientific sources published are considered to obtain sufficient literature coverage. Better tensile strength and fine microstructure are found in SLM, while better surface quality, fatigue load resistance, ductility, and residual stress are found in investment casting. The research gap for further investigation is indicated.

“…Given the high solidification reach of the SLM process, SLM fabricated AlSi10Mg presents much higher yield strength (about 300 MPa) (Chen et al , 2017; Kempen et al , 2012; Takata et al , 2017; Yan et al , 2020) than those prepared from casting (170 MPa) (Kaufman and Rooy, 2004). At present, Al-Si alloys increasing usage in many automotive and aerospace applications makes its market hold of approximately 80%–90% of all cast Al products (Hernandez et al , 2017). Adding Mg in cast Al-Si alloys enhances the alloy strength considerably due to the precipitation of semi-coherent Mg 2 Si that act as barriers to dislocation movement under stress (Shivkumar et al , 1990).…”

Purpose The present paper aims to systematically investigate the influence of building orientations (0°, 15°, 30°, 45°, 60°, 75°) and heat treatment processes on the macro-/micro-structural, mechanical and electrochemical behaviors of selective laser melting (SLM) prepared AlSi10Mg alloy parts. Design/methodology/approach AlSi10Mg samples were produced by the SLM method using standard processing parameters at 0°, 15°, 30°, 45°, 60° and 75° building angles. The effects of building orientations on the physical, mechanical and electrochemical properties of the alloy were investigated. Findings With the increase in the building orientation from 15° to 75°, the structural defects were found reducing. The effect of step size of inclined geometries was found to significantly influence the mechanical and electrochemical properties of the AlSi10Mg samples. Tensile strength for samples fabricated at lower angles (0°, 15°, 30°) reported a drop of approximately 11% than SLM 0° samples. Moreover, the tensile strength was found to decrease from 412.35 ± 9.568 MPa for the as-built samples to 290.48 ± 12.658 MPa, whereas the fracture strain increases from 3.32 ± 0.56% to 5.6 ± 0.6% when the as-built sample was treated with T6 treatment. This study indicates that the microstructure and mechanical properties of SLM-processed AlSi10Mg alloy can be tailored by a suitable heat treatment or building angle. Originality/value Microstructural and mechanical behavior of horizontal or vertically built SLM components have already been demonstrated several times. However, the influence of different building orientations, such as 0°, 15°, 30°, 45°, 60°, 75°, has not been explored in-depth, particularly on corrosion and general mechanical performance. As a result, this work may be of significant relevance to academics and designers, given the varying orientation of internal component of SLM structures.
