Create the material Titanium in the Materials editor and assign it to the Design Space. In this case the material behaviour is Isotropic.
The specific values needed are the Young's Modulus (116e3 MPa), Poisson ratio (0.26) and Density (4.48e-6 kg/mm3).
The Tension Strength is the maximum allowable stress for the material and is set to 1290 MPa.

Two Interfaces are created for the load application surfaces. Therefore, an Non-Design Space Thickness of 2 mm and a Machining Allowance of 1 mm is entered. Because not only the inner faces touching the screw but also the front and back face are supposed to contain material and have sharp, functional faces, an Offset Distance of 3 mm is entered. Now select the inner surfaces of the force application face and confirm the selection (MMB). When the Interface Thickness is equal or bigger than the Offset Distance, the inner offset (Non-Design Space) is t isn’t visualized but will be considered correctly in the optimisation.
Four Interfaces are created on the faces of the fixations. Therefore, an Non-Design Space Thickness of 3 mm and a Machining Allowance of 1mm is entered. Now select the top plate and confirm the selection (MMB). Because not only the inner faces touching the screw but also the front and back face are supposed to contain material and have sharp, functional faces, an Offset Distance of 3 mm is entered. Now select the inner surfaces of the fixations and confirm the selection (MMB).
Step 5: Definition of Events (load cases)

Inside the Post Processing the von Mises stress and the displacements are visible for all iterations and for every Event. The Scale can be influenced individually

Generative Design Results
You can always change the Strut Density, Stress Goal and Complexity to influence the results and try out different options
The Complexity can be increased for a higher resolution and more detailed result (increased calculation time!)
