2 Create Mold

Wall Thickness (mm) ? How thick the mold walls will be. 3mm works for most prints. Use thicker walls (5-8mm) for larger models.

3 Split Mold

Cut Axis ? Which direction to split the mold into two halves. Z (front/back) is most common for figurines and vertical objects.

Cut Position

Cut Angle (°)

4 Contour Split NEW

Cut Axis ? Pull direction for the mold. The contour surface is generated perpendicular to this axis to minimize undercuts.

Cut Position

Cut Angle (°)

Resolution ? Grid resolution for sampling the model profile. Higher = more detailed parting surface but slower to generate.

Smoothing ? Blur passes. More smoothing produces gentler curves. 0 = raw profile, 3 = typical, 10 = very smooth.

Auto-optimize ? Automatically finds the split position at each grid cell that minimizes undercuts. Replaces manual Bias when enabled. Bias ? Where to place the split within the model depth. 0% = back surface, 50% = midpoint (balanced halves), 100% = front surface.
