A biocompatible method for general construction of 3D structures by aggregation of micrometric polymeric subunits is presented. Shape-controlled microgels are forced to self-assemble, in a structure similar to a brick wall, in different shapes by limiting their movement onto a surface. Scaffolds with high spatial resolution in the aggregation and composed by the addition of multiple layers are produced.
