... fiber reinforced onyx (carbon-filled nylon) 3D-Printed composites have been designed and tested at 40°C, 60°C and 80°C for fiber volume fractions ranging from 13%, 20%, 27%, 33% and 40%. Findings The results of three-point bending tests have shown that at higher temperatures, i.e. greater than...

...Giampiero Donnici; Marco Freddi; Alfredo Liverani Purpose In this study, response surface methodology (RSM) is applied to a three-point bending stiffness analysis of low-cost material (PLA) specimens printed using FDM technology to analyze the performance of different internal lattice structures...
