Tensile Test Specimen A tensile test specimen is a standardized sample used in tensile testing to evaluate the mechanical properties of a 3D printed material, including tensile strength, elongation, and Young's modulus. Specimen dimensions, shape, and preparation follow industry standards like ASTM D638 or ISO 527 for accurate and repeatable results. Proper printing orientation, layer height, and infill patterns influence tensile properties. Advanced testing equipment measures stress-strain behavior, providing valuable data for material selection, design optimization, and quality assurance. Tensile test specimens validate performance and safety for functional parts and load-bearing applications. |
