How to Use This Calculator

Enter the sculpture's bounding box dimensions in inches (height, width, depth).
Select complexity: 0 = simple (few undercuts), 1 = moderate, 2 = complex (many undercuts, fine detail).
Select mold rubber type: tin-cure silicone (~$18/lb), platinum-cure silicone (~$28/lb), or urethane rubber (~$14/lb).
Review total material cost, silicone needed in lbs and gallons, and the cost breakdown chart.
Mother mold (rigid outer shell) cost is calculated separately from the rubber cost and added to the total -- budget extra for plaster or fiberglass shells on large molds.

How the result changes with Sculpture height (in)

Sculpture height (in): Overall height of the sculpture to be molded.
Sculpture width (in): Maximum width of the sculpture.
Sculpture depth (in): Maximum depth (front to back) of the sculpture.
Complexity: 0 = simple (few undercuts), 1 = moderate, 2 = complex (many undercuts, fine detail).
Mold rubber type: 0 = tin-cure silicone (~$18/lb), 1 = platinum-cure silicone (~$28/lb), 2 = urethane rubber (~$14/lb).

Total material cost: Combined cost of silicone, mother mold, and supplies.
Silicone needed (lbs): Weight of silicone rubber required.
Silicone (gallons): Volume of silicone rubber in gallons.
Silicone cost: Cost of the silicone rubber alone.
Mother mold cost: Cost of rigid outer shell (plaster or fiberglass).
Number of mold pieces: Recommended number of mold sections.
Wall thickness (in): Recommended silicone wall thickness.
Surface area (in²): Estimated effective surface area including detail factor.
Est. labor hours: Estimated time to complete the mold.
Silicone volume (in³): Total silicone volume in cubic inches.

Calculate Total material cost
Total material cost = siliconeCost + motherMoldCost + miscSuppliesCost
649.49 = $649.49
Calculate Silicone needed
Silicone needed = siliconeGallons * 10.8
19.7 = 19.7
Calculate Silicone
Silicone = siliconeVolumeIn3 / 231
