How to Use This Calculator

Enter the sculpture's bounding box dimensions in inches (height, width, depth).
Select complexity (1=simple, 2=moderate undercuts, 3=complex/multi-part mold).
Select mold rubber type (tin-cure silicone, platinum-cure silicone, or polyurethane rubber).
Review total material cost, silicone in lbs and gallons, and cost breakdown.
Shell cost (mother mold) adds 20-40% to rubber cost -- plan for plaster or fiberglass shells on large molds.
