| Abstract Scope |
Additive manufacturing (AM) with polymers is widely adopted in industries such as aerospace, automotive, healthcare, and consumer products, due to benefits like rapid prototyping, diverse materials, cost efficiency, and complex manufacturing capabilities. AM's quick, economical approach eliminates tooling and minimizes waste, promoting sustainability and reducing inventory through on-demand production. However, polymer AM faces challenges with interlayer adhesion, impacting mechanical properties. This has spurred research into improving interlayer bonding in Fused Deposition Modeling (FDM), leading to innovations like bead-weaved layered prints. These techniques aim to leverage AM's anisotropic mechanical properties by aligning material deposition with expected strain fields using multi-axis 3D printing. We propose testing two hypotheses: 1) Bead weaving will change the shear and tensile stresses in AM parts, enhancing structural integrity. 2) Alternating deposition patterns will reduce stress concentrations at interfaces, achieving uniform mechanical properties, thus broadening the practical applications of polymer-based AM. |
