Miniaturized Testing Machine

Miniaturized testing machine

The Miniaturized Testing Machine (MTM) for simple tensile testing was developed at COMTES FHT and is designed to quickly verify the mechanical properties of samples printed by additive technology on a 3D printer. The MTM is a compact and mobile device with fast and simple specimen clamping, with which we can measure mechanical properties and evaluate force-displacement and stress-strain curves. Testing can be performed according to ISO/ASTM 52909:2022 - Additive manufacturing of metals - Properties of finished parts - dependence of mechanical properties on orientation and location in powder bed technology. The equipment can be extended with a DIC system, different jaws according to the required specimen geometry and integrated measurement of specimen dimensions before and after testing.
