Resin Casting Calculator for Scale Modeling
Calculate precise resin-to-hardener ratios, mold volumes, and material requirements for your casting projects
⚗️ Resin System & Mold Configuration
Different resin types have different mixing ratios and properties
Mixing ratio (Resin:Hardener). Common ratios: 1:1, 2:1, 3:1, 100:30
Typical resin density: 1.0-1.2 g/ml. Check your product specifications.
Mold Volume Calculation
Rectangular
Cylindrical
Custom
How many parts will you cast at once?
Extra material to account for spills, mixing losses, and overpour
⏱️ Casting Parameters & Material Costs
Higher temperatures accelerate curing, lower temperatures slow it down
Curing & Demolding Times
Working time before resin starts to gel
Time until parts can be removed from mold
Advanced Settings
Account for pigment volume in calculations
Typical pigment: 1-5% of total resin volume
