摘要：

Residual stresses and strains generated in additively manufactured (AM) components have significant impact on their dimensional integrity. This work aims at characterizing the residual strains and deformations in square plates fabricated using the fused deposition modeling (FDM) process. The induced residual strains at the end of the printing process were measured through the integration of fiber Bragg grating (FBG) sensors, while the exhibited out-of-plane deformations of the plates were obtained using the digital image correlation (DIC) technique. The experimental results demonstrate significant part distortions at the plates' corner locations but without proceeding to quantitative correlation between the FBG and the DIC measurements. © 2020 John Wiley & Sons, Ltd.
