Fabrication of bio‐templated metallic structures is limited by differences in properties, processing condition, packing, and material state. Herein, we demonstrate that using undercooled metal particles, differences in modulus and processing temperatures can be overcome. Similarly, adoption of autonomous processes like self‐filtration, capillary pressure and evaporative concentration leads to enhanced packing, stabilization (jamming) and point sintering with phase change to create solid metal replicas of complex bio‐based features. Differentiation of subtle differences between cultivars of the rose flower with reproduction over large areas shows that this BIOmimetic Metal Patterning (BIOMAP) is a versatile method to readily replicate biological features either as positive or negative reliefs irrespective of the substrate. Using rose petal patterns, we illustrate the versatility of bio‐templated mapping with undercooled metal particles at ambient conditions, and with unprecedented efficiency for metal structures.
