DeepSDFStruct.splinepy_unitcells

Splinepy Unit Cell Library

This module provides a collection of spline-based unit cell geometries for lattice structures. These are built using the splinepy library and can be used with the LatticeSDFStruct class.

Available Unit Cells

CrossLattice (cross_lattice.py)

2D cross-shaped lattice with configurable strut thickness.

Chi3D (chi_3D.py)

3D chi-shaped lattice structure, common in mechanical metamaterials.

Snappy3D (snappy_3d.py)

3D snappy lattice with snap-through behavior.

DoubleLatticeExtruded (double_lattice_extruded.py)

Extruded double lattice structure.

All unit cells inherit from splinepy’s TileBase class and provide: - Parametric thickness control - Sensitivity computation for optimization - 2D and 3D variants - Integration with the DeepSDFStruct framework

These geometries are particularly useful for: - Mechanical metamaterial design - Additive manufacturing - Topology optimization - Multi-scale structural analysis
