Digital Restoration: Caligula Sculpture Scale Bronze

Picture
Challenge: The Caligula Sculpture (Roman AD 38-40)

Solution:
  • Developed stabilization strategy to scan at height with high resolution wide beam laser scanner
  • 3D laser scan the sculpture on-site
  • Compile high resolution digital model
  • Rapid-prototype an 8 inch model for form approval
  • Separate the wreaths from arms and head for building in large scale rapid prototype
  • 5-axis mill remainder of sculpture in 10 lb foam
  • Physical models delivered to Polich Tallix foundry
