Influence of calcium stearate incorporation on the rheological behavior of PLA filaments for 3D printing

Data obtained during and after processing of polylactic acid (PLA) modified with calcium stearate. The “during” phase refers to samples analyzed after processing in a torque rheometer and after extrusion, while the “after processing” phase refers to the printed 3D part. The dataset includes thermal analyses (DSC and TGA), rheological measurements (parallel plate rheometry and MFI), molar mass characterization (GPC), morphological evaluation (optical microscopy), and spectroscopic analysis (FTIR).
