Simulation and strength tests of spatial structures of models obtained by 3D-FDM printing
PRZEMYSL CHEMICZNY(2020)
Abstract
Six geometric models with different internal structures were designed by using a computer-aided procedure (shape program) and 3-dimensionally printed by incremental technol. A polyol-modified and SiO2 nanoparticles-filled polycarbonate was used as the filament. The model with the large hexagon structure showed the highest compressive strength and with the circular structure showed the lowest one. A large discrepancy between the simulated and actual values of compressive strength was obsd.
