1. A process for creating an object, comprising:
depositing a mat on a substrate, the depositing comprising at least one of:
forming a fiber mat by at least one of electrospinning at least one fiber, or melt blowing at least one fiber; or
electrohydrodynamic spraying a membrane layer to define the mat as a membrane mat;
using a controller to perform a fused deposition modeling process to print a frame by positioning a structure over at least a portion of the mat to define an object that comprises at least a portion of the mat being suspended between members of the frame; and
removing the object such that a first portion of the mat removed with the object is bonded to the structure and a second portion of the mat removed with the object is unsupported by the structure.
