Systems and methods for controlled laydown of materials in a fiber production system

A method of producing microfibers and/or nanofibers, comprising:

• placing material into a fiber producing device, the fiber producing device comprising a body comprising one or more openings and a coupling member, wherein the body is configured to receive material to be produced into a fiber;
• rotating the fiber producing device at a speed of at least about 1000 rpm, wherein rotation of the fiber producing device causes material in the body to be ejected through one or more openings to produce microfibers and/or nanofibers;
• directing fibers produced by the fiber producing device toward a substrate disposed below the fiber producing device using a deposition system, wherein the deposition system comprises:
• an airflow system that draws air through the substrate such that fibers produced by the fiber producing device are drawn toward the substrate;
• an airflow control system configured to adjust an airflow rate through one or more regions of the substrate;
• a static plate positioned below the substrate and including a louver chamber, wherein the louver chamber houses a louver that controls the air flow rate through the one or more regions of substrate.
