| Abstract Scope |
This work gives an overview of a novel decision-making process for designing additively-manufactured thermoplastic lower-limb prosthetics. The framework is based on analytical hierarchy process (AHP) decision making, where patient information, stakeholder (doctor, patient, others) wishes, and realistic manufacturability constraints using AM are all considered. Instead of a process where a single design or alternative is selected, the AHP method allows the stakeholders to rank and simultaneously evaluate several close or imperfect options for design. A usable tool written in MS Excel and Python is provided, along with a tutorial for use in realistic scenarios. This will be supported by a detailed long-form case study which includes the design and prototyping of several design alternatives using both primitive shape design and topology optimization. Patient data for the case study was taken from published literature sources, so no human subjects were directly used for this project and IRB approval was not necessary. |
