Test of Designing and Manufacturing a Polyether Ether Ketone Endoprosthesis for Canine Extremities by 3D Printing

Total limb amputation is quite common in small animals, although most of the indicated pathologies do not need such a restrictive procedure. Exo-endoprosthesis suggested alternative for enhancement biomechanical situation these patients. 3D printing internal part exo-endoprostheses polyether ether ketone (PEEK) evaluated. Two different shapes this part—one radius’ and other cylindrical medullary cavities—were assessed. Proper PEEK temperature settings printing, exo-endoprostheses, by fused filament fabrication (FFF) were obtained. Printing trials carried out dimensions orientation parts to achieve best bone anchorage thread strength outcomes. Pull-off tests surfaces performed with outcome positive surfaces. All printed inserted canine tibiae radii an ex vivo assessment parameters. The results obtained at 410 130°C nozzle bed temperatures, respectively. Also, correlation was observed between code, quality, take-off time, while inverse shown or just like print-bed code. had pull-off Excellent outcomes one variant each shape. Designed devices good threaded rod’s fitting inside plug perfect radii. In addition, iteration manufacturing FFF technology has been due standard deviation variants.
