Residual Stresses Distortion Material Extrusion Project Details
| Abstract |
Material extrusion additive manufacturing of reinforced thermoplastic composites experiences large thermal gradients, which create residual stresses and cause the part to warp. This review examines the basic causes of that stress: thermal contraction, crystallization kinetics, and the interaction between fibers and the matrix during the layer‑by‑layer build. It looks at how key process settings affect warpage and delamination, specifically: – nozzle temperature – bed temperature – print speed – fiber volume fraction The study also surveys current numerical modeling tools, such as finite element analysis (FEA) and thermomechanical simulations, that can predict distortion patterns in printed parts. Mitigation approaches are organized into three groups: – toolpath optimization – in‑situ heating
during printing – post‑processing thermal treatments These categories are meant to guide future experimental work and computational studies. The review provides a solid base for creating predictive models and optimization procedures that improve the dimensional accuracy and structural integrity of printed composite components for advanced engineering applications.
