F13LD.mesh
F13LD.mesh converts a recipe into a watertight, printable mesh. It accepts a recipe from any tool, rebuilds the geometry, and exports a 3MF. It is the final stage before printing.
What it does.
Before this stage a design is a recipe — a set of parameters describing a field. F13LD.mesh evaluates the field, extracts the level-set surface, and produces a watertight mesh: a single closed shell with no gaps or self-intersections, which is what a printer requires.
It is normally the last tool in a workflow rather than a starting point. A design is finalized in a design tool, then meshed here.
Where it fits.
Every design tool has an Open in F13LD.mesh control. It passes the recipe to F13LD.mesh by URL, so no file is saved or re-imported in between.
Worked example: meshing a recipe.
Bring a recipe in
Three inputs are supported: the Open in F13LD.mesh control in a design tool, dropping a recipe JSON file onto the window, or the file picker. A recipe can also be passed in the URL.
Inspect the preview
F13LD.mesh rebuilds the field and renders a watertight preview. Check for walls thinner than the printing process can resolve, and for regions that are not connected to the main body.
Choose a quality tier
Select Draft, Standard, or Fine. The tier sets the mesh resolution, trading surface detail against file size and build time.
Export the 3MF
Export a watertight 3MF. It carries the geometry into the printing workflow without a separate repair step.
Coming from a design tool, use its Open in F13LD.mesh control; the recipe loads here automatically.
Output and quality tiers.
A printable mesh must be a single closed surface — every edge shared by exactly two faces, with no holes or overlaps. F13LD.mesh enforces this during generation, so the exported 3MF does not require a separate repair pass.
The quality tier is the main parameter. Draft is for checking the shape, Standard for general use, and Fine where surface smoothness or small features matter. Higher tiers increase file size and build time without otherwise changing the geometry.
