STL files Test specimen

A dogbone test specimen is used in 3D printing and material testing to evaluate mechanical properties, particularly tensile strength. It ensures uniform stress distribution, follows industry standards, prevents grip stress concentration, aids in material characterization, and aids in layer adhesion and print quality analysis in 3D printing, assessing anisotropy, layer bonding, and print orientation influence.

哑铃形试样（dogbone test specimen）被应用于3D打印与材料测试领域，用于评估材料的力学性能，尤其是拉伸强度。该试样可确保应力均匀分布，符合行业标准，能够避免夹持端应力集中；同时有助于材料特性表征，还可用于3D打印中的层间附着力与打印质量分析，用以评估各向异性、层间结合强度以及打印取向的影响。
