Materials and Manufacturing of Alloy Exoskeletal Fingers
An overview of the materials, manufacturing processes, durability, and design of alloy exoskeletal fingers.
Precision Reconstruction Using array laser scanning and kinematic simulation, BIOCAT accurately reproduces each residual finger’s movement and designs the structure and joints accordingly, achieving a millimeter-perfect fit.
Materials
- Aerospace aluminum alloy: light and strong, for the skeleton.
- 316L stainless steel: corrosion-resistant and durable, for high-strength parts.
- Titanium alloy: high strength-to-weight ratio, biocompatible.
- HP nylon: flexible and customizable.
- Honeywell conductive silicone: conductive and skin-friendly.
Manufacturing
SLA, SLM, and 4-axis CNC ensure precision and batch consistency.
Durability
- Alloy products pass rigorous fatigue testing.
- Lifetime warranty on the skeleton; 3–6 years on consumables.
- All-metal single finger: 20–60 g; metal backplate: approx. 50 g.
Design
Refined, per-person hand-shape designs fit Asian hands better and look more natural.
