The micro-molding of bulk amorphous metal to create sub-micrometer to sub-millimeter surface features was investigated. The goal was to demonstrate the reproduction of such features in a metallic material from a master. The bulk metallic glass material was embossed between the glass transition and crystallization temperatures. Silicon wafers patterned by deep reactive ion etching were used as masters. The patterns were designed to test the effects and interactions of aspect ratios, geometry, and spatial proximity. In addition to these patterns, a master was developed to mold two-dimensional channel geometries. Comparisons between the replicated features and the molds are provided.
