The OPTIMIZE tab contains components used to improve a design based on performance targets, simulation fields, manufacturability constraints, and post processing steps. It includes Simulation Driven Design (field-driven redesign), Manufacturing Driven Design (DfM fixes), lightweight infill generation, and topology optimization post processing.

Simulation Driven Design

Redesigns a part so that its local thickness follows a simulation result: material where the part is working hard, less where it is not. Pick the redesign method from the dropdown.

The four inputs every method shares

• Part (Mesh) — The geometry to redesign.
• Frep — The driving field, normally a stress or displacement field from Extract Field.
• Min / Max — The value range of that field. Extract Field outputs its own Min and Max; wire them straight in. These two numbers anchor the mapping: wherever the field equals Min the part gets the minimum thickness, wherever it equals Max it gets the maximum, and everything between is interpolated.
• Functional regions (Opt.) (Mesh) — Surfaces to preserve untouched.

How to control the result

Raising Min or lowering Max narrows the window the field is read over, which makes the thickness variation more pronounced across the part. Feeding in the true field range gives the most faithful mapping. If the result looks uniformly thick or uniformly thin, the range is almost always the cause.

Shared parameters: Functional Regions Thickness (mm — default 5) is the material kept around the preserved surfaces, and Blend Radius (mm — default 1) is the fillet where the new structure meets them.

Variable TPMS Infill

Hollows the part and fills it with a TPMS structure whose wall gets thicker in the loaded regions. Good stiffness-to-mass, no sharp internal junctions, and both internal channels stay connected so powder or resin can escape.

Parameters

• Minimum TPMS thickness (mm — default 1, range 0.5–10) — Wall thickness where the field is at its Min. Keep it above the minimum feature size of your process, or the lightly loaded regions will not build.
• Maximum TPMS thickness (mm — default 6, range 0.5–10) — Wall thickness where the field is at its Max. Raise it if the highly loaded regions are still too flexible.
• Shell thickness (mm — default 2, range 0–100) — Solid outer skin kept around the infill. Set 0 for a bare infill with no skin. A skin is normally worth keeping: it carries bending load and gives a finished outer surface.
