(54) Title: SYSTEMS AND METHODS FOR PRINTING A FIBER STRUCTURE (57) : Aspects of the invention include systems and meth- FIG. 3 ods for producing fiber structures, and for producing three-dimensional (3D) biological structures from digital files. In some embodiments, the printed fibers comprise living cells. Aspects of the invention further in- clude a print head for producing the fiber structure, the print head com- prising: a dispensing channel comprising a distal and proximal end; a dispensing orifice located at the distal end of the dispensing channel; one or more material channels converging with the dispensing chan- nel at its proximal end; a buffer solution channel converging with the one or more material channels at the proximal end of the dispensing channel; and a sheath solution channel converging with the dispensing channel at a position located between the proximal and distal ends of the dispensing channel. The print head is configured to displace one or more input materials with a buffer solution at the proximal end of the dispensing channel to terminate the fiber structure with a clean tail end.
