Emerging additive manufacturing for load-bearing components and structural repairs can be accelerated by combining process modeling control and in-situ monitoring along with non-invasive physical testing on qualifying parts where mechanical properties are quantified using new solutions. This study discusses two non-invasive solutions that are applied to cold spray coatings and selective laser sintered (SLS) components to perform a direct assessment of strength and toughness for a variety of process conditions. The first device is the Hardness, Strength, and Ductility (HSD) Tester, which performs a frictional sliding test where multiple hard styluses generate shallow grooves that are used to measure the tensile yield and ultimate strength properties. The other instrument is the Nondestructive Toughness Tester (NDTT), which uses a wedge-shaped stylus to induce a tensile fracture response in a ligament of material. The recorded measurements are validated with traditional destructive laboratory tests from the same specimen.
