Abstract Sandwich structures have garnered interest as versatile for applications in advanced engineering structures. To fabricate sandwich structures, plastics replaced conventional materials; however, most of these remain the environment beyond their functional lifespan. This study describes fabrication sustainable hybrid with 3D printed poly‐lactic acid (PLA) cores and self‐reinforced polyethylene terephthalate (srPET) face sheets.

This study examines the effect of different infill patterns and percentages on compressive strength attributes carbon fiber-reinforced PETG samples printed using fused deposition modeling, employing response surface methodology. Carbon fiber-enhanced (polyethylene terephthalate glycol) composites represent a cutting-edge advancement in additive manufacturing, drawing significant interest due to their impressive mechanical attributes. The experimentation involves modifying printing parameters such as pattern (tri-hexagon, cubic, or line) density (40%, 60%, 80%). These parameter values were obtained through central composite experimental design utilizing 3D-printed specimens is assessed following ASTM D695 standards. Research indicates that increasing results enhanced strength. Specifically, featuring an 80% with tri-hexagon demonstrate notable 39.16 MPa. By regression analysis optimization techniques, predicts outcomes accurately. findings offer valuable insights into refining manufacturing process components. holds potential benefits across various engineering fields, particularly automotive aerospace industries, where durability are essential.
