List of Abstracts 2024: SESSION A - ADDITIVE MANUFACTURING I

Leveraging the design freedom of additive manufacturing, this study investigates the tensile properties of two-dimensional hexagonal lattice structures fabricated from 316L stainless steel, Ti-6Al-4V titanium alloy, and photopolymer resin. These lightweight structures, characterized by high stiffness-to-weight ratios due to their cellular architecture, hold promise for various applications, particularly in biomedicine where weight reduction is crucial. A combined experimental, analytical, and numerical approach is employed to elucidate the mechanical behavior of these lattices. This investigation provides valuable insights for the design and optimization of lattice structures for specific engineering applications.

Additive Manufacturing (AM) has witnessed a surge in popularity. To ensure its successful integration into engineering structures, a thorough understanding of its mechanical properties for specific applications is imperative. AM-deposited structures are notorious for their sensitivity to deposition location, orientation, wall thickness, and other critical parameters, leading to significant variations in mechanical properties.
A major challenge in AM-deposited components is their size dependency, often rendering standard-sized samples unsuitable. Surface quality also plays a crucial role in determining mechanical properties. While standardization efforts for mini-samples have been initiated, primarily for tensile testing, fatigue, fracture toughness, and creep tests remain inadequately addressed.
This paper presents a comprehensive overview of the utilization of mini-samples for these tests and the ongoing standardization activities within this field of interest.
