High-Sensitivity DMA of 3D-Printed Foams
3D printing enables the customized production of a wide variety of different structures. Distinguishing and further characterizing these structures is essential for their future use.
Even though some materials appear similar under high loads, their behavior under low loads might differ significantly. Dynamic mechanical properties of differently structured 3D-printed polyurethane foams can be analyzed using Anton Paar’s modular compact rheometer (MCR) in combination with a linear drive (LD). The high resolution of the force measurement makes it possible to investigate how materials respond under low loads, to distinguish between different materials, and subsequently to develop materials with specific properties for different applications.
