Claims15
A system for generating an array of polymeric fibers, the system comprising;
- a frame configured to support the system;
- a top track having a top track surface configured to actuate with respect to the frame;
- a bottom track having a bottom track surface facing the top track surface and configured to actuate with respect to the frame;
- a polymeric solution or melt source configured to dispose a volume of polymeric solution or melt between a portion of the top track and a portion of the bottom track within a deposition section of the system;
- a production section extending distally away from the deposition section;
- and
- a collection element at an end of the production section;
- wherein a distance between the portion of the top track and the portion of the bottom track increases as the portion of the top track and the portion of the bottom track actuates distally away from the deposition section in the production section;
- wherein the portion of the top track and the portion of the bottom track are configured to maintain contact with the polymeric solution or melt through the production section as the distance between the portion of the top track and the portion of the bottom track increases, the increasing distance elongating the polymeric solution or melt and drawing a plurality of polymeric fibers throughout the production section;
- wherein each of the fibers corresponds to an individual outlet for the polymeric solution or melt source;
- wherein a length of the fibers corresponds to the distance between the portion of the top track and the portion of the bottom track at the end of the production section;
- and
- wherein the collection element is configured to collect the fibers.
