Abstract:Background: This research paper presents a comprehensive parametric study that investigates the influence of various 3D printing parameters on the mechanical properties of a paediatric prosthetic keel using coupon samples.
Objective: To analyse how 3D printing parameters impact upon on two crucial mechanical properties: stiffness and hysteresis.
Methods: Key 3D printing parameters including the amount of continuous carbon fibre layers, fibre distribution, and matrix fill pattern, are systematically varied, and mechanically tested through compression to analyse the results.
Results: The results demonstrate the substantial impact that printing parameters have on the mechanical characteristics of 3D printed paediatric prosthetic feet. Notably, the selection of these parameters for the prosthetic keel plays a pivotal role in shaping the overall performance and functionality of the prosthetic foot, emphasising the need for precise parameter optimisation in paediatric prosthetic design, if 3D printing is the manufacturing process.
Conclusion: The findings of this study contribute to a better understanding of the manufacturing process for paediatric prosthetic feet via 3D printing and offer valuable insights for optimising their design. By identifying the ideal combination of 3D printing parameters that yield the desired stiffness and minimise hysteresis, we aim to enhance the performance and comfort of paediatric prosthetic de-vices, ultimately improving the quality of life for young users.
