摘要：

In this paper, we describe a rapid method for fabricating a low density polymer microlattice with structural organization on two length scales. The topology of this hierarchical cellular structure is achieved through the in situ formation of a microlattice with small-scale lattice members (approximate to 100?mu m diameter) within a microlattice with approximately 12 times larger feature sizes. Compression experiments suggest that an increase in the specific plateau stress is realized by the introduction of hierarchy.
