Physical properties

Hardness: 2-3 (Mohs scale), Color: iridescent red/purple and blue/black gradient, Luster: Silk-like/Metallic sheen, Structure: Layer-by-layer FDM deposition, Specific Gravity: 1.25

Formation & geological history

Manufactured via Fused Deposition Modeling (FDM) 3D printing. PLA is derived from renewable resources like corn starch or sugarcane. This specific piece was printed using 'silk' bi-color filament.

Uses & applications

Decorative figurine, artistic expression, or hobbyist demonstration of 3D printing technology.

Geological facts

PLA is a biodegradable thermoplastic. The visible 'layer lines' across the elephant's body are a hallmark of the FDM printing process, where thin strands of melted plastic are stacked to form a shape.

Field identification & locations

Can be identified by the geometric layer lines, lightweight feel, and plastic-like warmth to the touch. It will melt or deform under high heat (above 60°C).
