The incremental deposition process utilized by most additive manufacturing (AM)
technologies presents significant challenges related to residual stresses and warping which
arise from repeated deposition of hot material onto cooler material. These issues are
magnified at larger scale, where even a small thermal strain can correspond to several
millimeters of deformation. In this work we investigate the thermal evolution in thin walls of
carbon fiber/acrylonitrile butadiene styrene (CF/ABS) composite materials fabricated via Big …
