Creating perforated or lattice-like metal sculptures involves a blend of artistry and precision engineering. Among the most popular techniques is laser cutting, which uses high-powered lasers to etch intricate patterns into metal sheets with exceptional accuracy. Waterjet cutting is another favored method, employing a high-pressure stream of water mixed with abrasives to carve detailed designs without heat distortion.

For traditionalists, hand-punching and drilling remain viable options, allowing artists to manually create patterns with chisels, punches, or drill bits. This technique offers a tactile, organic feel but requires significant skill and patience. Plasma cutting is also widely used, especially for thicker metals, as it melts through material with a plasma torch to form complex latticework.

Modern sculptors often combine these methods with digital fabrication, using CAD software to design patterns before executing them with CNC machines. Whether for architectural installations or standalone art pieces, these techniques enable endless creativity in metal sculpture.
