Mold Making & Casting Calculators

Estimating the amount of material needed for a project can be a difficult task. Not having enough material or having too much left over is not only frustrating, but costly. To assist you with these calculations, we are happy to provide the following tools.

Smooth-On assumes no liability for loss or damage associated with use of these calculators. If this is a critical project, we encourage you to verify the results using the long-hand method of correlating the yield of the material with the dimensions of your model and/or mold box.
Accounting for Waste
You may consider adding 5% – 10% to any material estimate to account for waste, such as material sticking to the sides of your mixing containers, stir sticks, etc. In almost all cases, it is better to have too much material on-hand than not enough.
