Realistic Finger Prosthetic Silicone

Ordering Notice

This document outlines the standards for providing photos of fingers and palms when capturing them by oneself, in order to ensure image quality and data consistency, which will help generate more accurate silicone fingers/palms.

1. Photo Shooting Environment

1.1 Lighting Requirements

• Lighting should be even, with no visible shadows.

• Lighting conditions must be consistent across all photos.

1.2 Background Requirements

• The background must be white (e.g., white paper, white drawing board).

• The background in each photo should cover the entire frame except for the finger, as much as possible.

2. Equipment Parameters

2.1 Recommended Equipment

• Use a smartphone or camera with a high-resolution camera and AI capabilities.

• Ensure the camera is steady and focused.

2.2 Shooting Specifications

• Resolution: Between 4K and 8K (frame length no less than 4096 pixels and no more than 8192 pixels), no aspect ratio restriction, but each frame must include the entire finger.

• File format: JPEG or PNG.

• Exposure: Maintain consistent exposure across all photos (lock exposure to avoid auto-adjustment by phone), accurate color reproduction not necessary, but lighting must be the same for each shot.

3. Shooting Subject Requirements

3.1 Finger Photos (refer to provided sample for food-holding posture)

• Side view of the finger:
  Try to shoot at a perpendicular angle to the finger's side, focusing on the finger's front texture and details to ensure clarity.

3D Printed Nylon Mechanical Hand

1. Overview

The 3D-printed nylon mechanical hand is a high-precision, lightweight assistive device designed for disabled users. Using selective laser sintering (SLS) 3D printing, durable nylon powder material is fused into an anthropomorphic mechanical structure, fulfilling the needs of finger fractures or partial hand amputees in daily grasping tasks. The product is based on ergonomic principles to provide effective mechanical support.

Core Objectives

• Help users regain gripping ability: provide stable grip force and comfortable wear.

• Support independent living: allow users to grip objects with residual fingers, reducing reliance on others.

• Improve grip strength: compared with traditional products, the mechanical hand using SLS 3D printing is lighter and offers better user experience.

2.1 SLS 3D Printing Technology

• High Precision: SLS ensures accuracy within 0.1 mm, suitable for complex shapes and components.

• Material Advantage: Made from nylon, the product is strong, durable, and lightweight, reducing user burden.

• Structural Advantage: No need for support structures, enabling production of detailed and comfortable ergonomic shapes.

2.2 Ergonomic Design

• The shape and joints of the mechanical hand are biologically ergonomic, with movements close to natural human hand motions for comfort.

• Adjustable Joints: Parts can be repositioned and customized for user comfort.

• Multiple Gripping Modes: Includes pinch, open, hold, etc., suitable for diverse usage scenarios.

2.3 Easy Maintenance

• Modular Design: Allows user to assemble and disassemble easily for cleaning.

• Repair and Replacement: Damaged parts can be replaced quickly, ensuring product longevity.

3. Applicable Users

• Users with finger amputations or congenital deficiencies.

• Individuals with hand injuries or neurological damage leading to partial hand dysfunction.

4. Technical Advantages

4.1 Key Benefits

• SLS 3D Printing: Delivers excellent structural strength and long-lasting durability.

• Smooth Finish: Increases comfort and wearability.

• Precision Design: Based on ergonomic and motion simulation modeling, mimicking real hand actions as much as possible.

• Lightweight and Durable: High structural strength with minimal weight, suitable for daily use.
