Why isn't the TPMS/Lattice thickness constant when I distort it?

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:

Method 1: When building your TPMS, try this workflow:

    • Set the Walled TPMS to 0 thickness
    • Add a Remap Field block
      • Input the TPMS block 
      • Set X: X
      • Set Y: Y
      • Set Z: Z
    • Add a Thicken Body block
      • Input the Remap Field block
      • Set your thickness value

This should allow the TPMS to have a constant thickness.

Method 2: Normalize the Field of the TPMS by using the Custom Block, Normalize Field. This block is attached below. 

    • Add a Walled TPMS block and set your values (including thickness)
    • Add the Normalize Field block (import it first)
      • Input the Walled TPMS
    • Add a Set Field Bounding Box
      • Take the bounding box chip from the Walled TPMS block and insert it into the Bounding Box input

    The Walled TPMS which the cell sizes are not equal in every axis (ex. 5x5x20 mm) get thinner than input thickness.
    Each method in this help could not resolve it.
