Articulated Anatomical Hand (from CT scan)

The project

This life-size 3D model is a realistic human hand skeleton. It was created starting from a real CT scan to keep the true shape of the bones. After cleaning up the scan, custom joints were added directly into the design. The result is a highly accurate model that prints in one single piece and moves just like a real hand.

⚙️ Print-in-Place Kinematics & Anatomy
Unlike standard static models or complex multi-part assemblies, this hand is designed to be printed as a single, continuous piece:

• Zero Assembly Required: The complex mechanical joints are built directly into the geometry. Once the print is finished, the fingers and thumb are immediately ready to flex, extend, and move.
• Bio-realistic Movement: The internal joint constraints were specifically calibrated to respect the natural limits and range of motion found in a real human hand.

• Medical-Grade Accuracy: Features true-to-life representations of the carpal bones, metacarpals, and phalanges, preserving the organic textures and shapes of the original scan.

   

🎓 Perfect For:

• Clinical & Academic Study: A fantastic, hands-on visual aid for medical students, physical therapists, and anatomy teachers.
• Biomechanical Demonstration: Easily explains how the skeletal framework behaves during grasping, finger articulation, and thumb opposition.
• 3D Printing Showcase: An incredibly impressive project to demonstrate your printer's dimensional accuracy, bridging capabilities, and print-in-place tolerances.
• Artistic Reference: A great physical tool for artists and animators studying lifelike hand poses.

💡 Print Guidelines

• Format: 100% Print-in-Place.
• Material: Optimized for standard PLA. Rigid materials work perfectly to demonstrate the skeletal kinematics—no TPU or flexible filament is needed.

• Scale: Pre-scaled to match the proportions of an average adult human hand (1:1 scale).
