F13LD — Fully Implicit Engine for Lattice Design

Browser-Native · WebGL · No STL Intermediates

f13ld.app ↗

The open-source tool suite I build under Not a Robot Engineering. Nine single-file HTML tools, fully implicit from field math to watertight 3MF export. No proprietary lock-in. No mesh intermediates.

↗
TPMS
Surface Design

Implicit TPMS and PI-TPMS surfaces with real-time WebGL preview and FFT-CG mechanical homogenization.

↗
Sweep
Parameter Space

Multi-dimensional parameter space exploration with curated material databases and pore architecture metrics.

↗
Grain
Stochastic Fields

Directionally biased microstructures — spinodoids, Gaussian random fields, and hyperuniform kernel fields.

↗
Noise
Stochastic Fields

3D stochastic scalar fields as isosurface lattices — a non-periodic alternative to crystallographic TPMS.

↗
Bundle
Fiber Structures

Helicoidal fiber architectures — Bundle, Helicoid, Braid, and Plain Weave lattice topologies.

↗
Beam
Beam Lattices

Parametric strut-and-node truss lattices, thickened implicitly into watertight scaffolds for additive manufacturing.

↗
Ingest
Data Pipeline

Validate and ingest structure data from TPMS and Sweep into the Vault database with automated quality checks.

↗
Vault
Structure Library

Curated library of validated implicit lattice structures, searchable by application domain and performance target.

↗
Mesh
Geometry Export

Composite SDF meshing and watertight 3MF export — the output stage for all F13LD designs.

Specialties

Where standard CAD
stops, this begins.

Independent computational design consultancy focused on orthopedic implants, metamaterials, and bioinspired structure — from concept geometry to validated, print-ready deliverables.
