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.

Requirements

What you’ll need

Enrolled student in a relevant degree program, e.g., Mechanical Engineering, Mechatronics, Manufacturing Engineering, Medical Technology, Industrial Design, Product Design, Technical Design, or a comparable field with a focus on CAD, design, or manufacturing engineering.
Some experience with CAD software – e.g., Fusion 360, Meshmixer, Tinkercad, or Blender (experience with SolidWorks, CATIA, or similar is also welcome).
Basic understanding of FDM 3D printing (print parameters, materials, support structures, slicing).
Interest in parametric or generative design.
Careful, structured working style and technical aptitude.
Team player, self-initiative, and eagerness to learn.
Good German or English language skills.
