The tiered umbrella is one of Thailand's oldest and most sacred ornamental symbols. Constructing one of these ornate pieces, also called chatras, can take master artisans up to six months. However, researchers demonstrate a technique for constructing seven-tiered umbrellas using high-powered lasers, which dramatically reduces the production time. Employing carbon dioxide lasers, they were able to fashion umbrellas from stainless steel in a matter of days while preserving their intricate beauty.
