The fabrication of the composites was based on the protocol developed in our previous work to ensure effective production of the intended layouts . The first step was to prepare the materials for processing. The PLA was dried at 70 °C for 24 hours (POL-EKO dryer) to remove moisture. The hydroxyapatite powders were dried in a Thermo Scientific™ Vacutherm vacuum dryer at 100 °C for 24 hours under vacuum. PCL, on the other hand, was not subjected to additional drying as its melting temperature was only slightly above room temperature. As it was stored in hermetically sealed factory packaging, it was processed immediately after opening. After preparation, the materials were weighed, combined in the appropriate proportions in plastic beakers, and thoroughly mixed.
