Effect of Support Structures on the Deformation of AlSi10Mg Aircraft Parts Made Using DMLS

Optimization of Components with Topology Optimization for Direct Additive Manufacturing by DLMS

“…In spite of progress in the case of developing metal composite materials [58], EOS aluminum AlSi10Mg [59,60] (Light Metal for Motorsports and Aerospace Interior Applications, provided by the EOS GmbH Electro Optical Systems in the form of a gas-atomized metal powder) was set as the material of the structure. This alloy provides a favorable price-to-performance ratio, rendering it a cost-effective selection, and it is widely used for motorsports and aerospace applications [56,61]. The chemical composition of the material is given in Table 1.…”

“…The propose odology aims to address the challenges associated with preserving the integrit optimized structure during the additive manufacturing process while also compe for errors and limitations inherent in the AM process, such as self-supporting st and distortion compensation. This research seeks to integrate various aspects that ically addressed separately in the existing literature, including the influence of placement and deformation induced by thermal loading [56]. Kim investigated th ence of the placement, type, and size of supports on part deformation in his arti research served as a basis for simulating support placement and was extended t porate compensatory deformations into the CAD model, aiming to achieve a mo rately manufactured component [56].…”
