CAD PROFILES & TOPOLOGY LIBRARY
Schwarz Primitive (P)
A triply periodic minimal surface characterized by three mutually orthogonal intersecting plates. In CAD skeletal modeling, this translates to a simple cubic node-to-node beam network.
Application: Energy Absorption / Impact Mitigation
Gyroid
An intricately chiral, non-intersecting surface containing no straight lines or planar faces. Its skeletal graph features highly tortuous beam paths that promote excellent fluid permeability.
Application: Heat Exchangers / Orthopedic Implants
Schwarz Diamond (D)
A complex interpenetrating lattice structure where the skeletal beams form a diamond cubic crystal arrangement. Exhibits stretching-dominated mechanical behavior.
Application: Lightweight Aerospace Structural Cores
I-WP (Body-Centered)
Features a primary skeletal network identical to the Schwarz P surface, augmented by a secondary set of intersecting beams in the void spaces, creating a highly interconnected dual-mesh.
Application: Biomedical Scaffolds / Tissue Engineering
