Objective:
Learn how to use the Mix and Ramp block to blend two different types of TPMS together.Procedure:
The Mix block is what we use to blend the bodies together. To get a nice blend we need the bodies to be overlapping each other (so the block can use geometry from both to mix them). You decide the mixing factor, 0-1, where 0 is Scalar Field A and 1 is Scalar Field B. Using a Ramp block with the Mix block allows you to vary the mix factor along the part. 1. Set up the part and variables- Import your CAD body and then convert it to an Implicit Body.
- Create a variable of the Implicit Body and name it “Body Shape”.
- Open the Properties of the Implicit Body , and drag the Bounding Box chip into the Notebook to create a Variable of this parameter (this will be used in the final step).
- Add a Periodic Lattice block.
- Unit cell: Walled TPMS Unit Cell.
- Unit cell: Gyroid.
- Cell map: Rectangular Cell Map.
- Approx. thickness 1 mm.
- Unit cell: Walled TPMS Unit Cell.
- Duplicate the variable and change the Unit cell: Schwarz.
- Add a Ramp.
- Create a Plane from Normal for the Real Field input.
- Use the Min Point property from the Implicit Body “Body Shape” for the plane origin to place it at the bottom of the part.
- Set In min: 0 mm, In max: 10 mm, Out min: 0, Out max: 1.
- Create a Plane from Normal for the Real Field input.
- Add a Mix.
- Real Field A: Drag and drop the Implicit chip from the Gyroid Lattice.
- Real Field B: Drag and drop the Implicit chip from the Schwarz Lattice.
- Set the Factor to the Ramp.
-
Add a Set Field Bounding Box.
- Set the Real Field to the Mix block.
- Set the Bounding Box to the bounding box variable made at the beginning.
