About the role

Key responsibilities & impact

CAD design & modeling – designing, adapting, and developing 3D models for orthopedic aids and test components using accessible CAD tools (e.g., Fusion 360, Tinkercad, Blender).
Parametric & generative design – developing customizable, patient-specific models based on 3D scan data or measurement inputs.
FDM 3D printing – slicing & process optimization – preparing print files with slicing software (e.g., Cura, PrusaSlicer, OrcaSlicer), selecting appropriate print parameters and materials (PLA, PETG, TPU, bio-based filaments).
Quality assurance & post-processing – inspecting print results for dimensional accuracy, strength, and fit.
Printer operation & maintenance – supporting operation and upkeep of our FDM printer fleet.
Team collaboration – close coordination with software developers, orthopaedic technicians, and product development to make designs practical and manufacturable.
