Flexible joints performance assessment of additive manufacturing FDM 3D printed TPU.

ABSTRACT: Given the increasing adoption of flexible 3D-printed joints in the field of robotics, it is essential to characterize the stiffness/spring coefficient and damping of printed specimens to understand the effects of various processing parameters and their interactions under different loading conditions. This study aims to research the effects of 3D-printed parameters and geometric dimensions, i.e, printing density, layer thickness, raster angle, length, width, and height. The Box-Benken design of experiments is conducted to obtain 44 different parametric combinations to characterize the damping and spring coefficients [Formula: see text] under a dynamic load. The damping and spring coefficients are characterized using the minimum squared method. Depending on the force decomposition, the dampi
