Abstract

This research introduces the novel "Kraken-Gear" mechanism, emphasizing the advantages of additive polymer 3D printing in
high-ratio gearbox systems for lightweight robotic applications, such as surgical instruments. The innovative kinematic solution
provides high torsional system stiffness, substantial gear ratios, and backlash-free transmission. Leveraging the "Hot
Lithography" additive manufacturing method ensures precise and warp-free gearbox components. Targeting medical technology,
the gearbox meets stringent requirements: backlash-free, minimal vibration, high precision, and torque, with minimized weight
for ergonomic comfort and fatigue mitigation. Computational simulations, assess forces and stresses, highlighting the potential
of additive manufacturing for cost-effective and functionally efficient gearbox fabrication. Nevertheless, careful material
selection remains imperative for optimal functionality, especially in demanding medical applications. In summary, this research
underscores a promising approach to gearbox fabrication, emphasizing the critical role of material selection and simulationbased
assessments for optimal performance.
