        abstract = {This study uses physics to improve transfer learning and transfer the thermo-elastic properties of additively manufactured short fiber-reinforced polymers (SFRPs) between extrusion deposition additive manufacturing (EDAM) systems. Microstructural changes in similar materials printed on different machines change material characteristics, necessitating extensive testing for each new printer to enable exact process simulations. The suggested system reduces material characterisation needed to create digital material cards for additive process simulations. This is done by deducing the fiber and matrix's thermo-elastic properties using numerical data on printed system effectiveness. Inferred characteristics and microstructural descriptors are used to predict an alternate printing system's effectiveness. The fiber orientation tensor from the second system is mostly needed for the transfer procedure, decreasing characterization burden. The expected composite coefficient of thermal expansion (CTE) for the second printing system matches numerical values, proving the framework's capacity to convey information across systems. We also perform a sequentially linked thermo-mechanical study of two geometries in an EDAM simulation to investigate prediction errors. The transferred CTE values predict residual and spring-in deformations that match numerical CTE values, verifying the proposed approach's accuracy and efficacy.},
