Issue:

I’ve distorted my TPMS and the thickness isn’t constant after I’ve distorted it.

​
Applies to:

  • Varying cell size
  • Warping
  • Remapping

​
Cause:

We are currently working on fixing this issue.

​
Solution:

A normalized field is a first-order approximation of the implicit function. Method: Normalize the Field of the TPMS by using the field property Normalized Field. This property is found in every field.
  • Add a Periodic Lattice block
    • Unit cell: Walled TPMS Unit Cell
      • Unit Cell: Gyroid
      • Orientation: UVW
    • Cell map: Rectangular Cell Map
      • Volume: Cube (Size: 10)
      • Cell size: 10 x 10 x 10 mm
    • Approx. thickness: 0mm

  • Use the “normalized field” chip or use the Normalize Field block.

  • Thicken the Normalized Field to your intended thickness
    • Use the Thicken Body block
      • Body: Normalized Field
      • Thickness: 1mm
  • Set Body Bounding Box to trim off the excess outside the design space.
  • Bounding Box: Bounding Box from the Periodic Lattice blockNormalizedTPMS.gif
