Filtration microstructure comprises a micromolded layer including a support element and a filter element that creates a tortuous channel with an inlet surface of openings and an outlet surface of openings for filtering matter. Microstructure layers can be stacked upon one another creating a labyrinth network of tortuous channels. The openings of the filtration microstructure are micromolded between and including 30 micron and 1200 micron. The support element, or wall thickness, between channels is between and including 90 micron and 3600 micron. Thus, the wall thickness to channel opening ratio is between and including 1:1 and 10:1, with a preferred ratio at 3:1. The filtration microstructure enhances and facilitates flow or navigation of particles to pass. Additionally, micro-filter assemblies with an integrated frame and filtration microstructure can be micromolded. Micromolding filtration microstructure eliminates the processing and manufacturing of filtration devices and materials including woven and extruded material.
