Objective:

Learn how to create a variable lattice thickness driven by 3D Simplex Noise in a Ramp. This technique is useful for creating Stochastic foam. 

Procedure:

1. Start with any Implicit Body.

2. Add a Ramp to use as a thickness modifier.

• • In the Scalar Field of the Ramp, add Simplex Noise 3D.
    • Change the frequency to vary the thickness.
  • Set the Ramp values:
    
    • In Min: -0.5, In Max: 0.75.
    • Out Min: 0.17 mm, Out Max: 0.8 mm (right-click on the Out Min and Out Max input names to turn them into variables, allowing you to easily change the beam thickness).

3. Add a Voronoi Volume Lattice. 

• Seed points: Random Points in a Body.
• Thickness: Ramp created from the above step.

4. Add a Trim Lattice.

• • Voronoi lattice: Voronoi Lattice.
  • Volume: Implicit Body.
  • Lattice to remain: Inside.
  • Feature tolerance: 0.1mm.

And that’s it! You’ve successfully created a lattice with a randomized beam thickness.
