This study explores the production of interference screws using 3D-printed PLA/PCL/HA biocomposite filaments, focusing on the effects of nozzle temperature and printing speed on screw quality. Experiments were conducted with nozzle temperatures of 205°C, 210°C, and 215°C, and printing speeds of 20 mm/s, 40 mm/s, and 60 mm/s. Density, torque, fracture analysis, and biodegradability tests were used to evaluate the screws. Results showed that higher nozzle temperatures and print speeds weakened layer bonds, increasing pores and reducing mechanical strength. The optimal setting was 205°C and 40 mm/s, yielding the highest density (1.30 g/cm3) and improved screw performance. Only screws produced at 205°C, 40 mm/s (S205K40), 205°C, 60 mm/s (S205K60), and 215°C, 60 mm/s (S215K60) met Good Clamping criteria. Fracture analysis indicated that all screws fractured at one-third of their length during torsion testing. © 2024 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group.
