Claim:
An apparatus for fabricating a 3D scaffold that can be inserted into a human body so as to be used to regenerate tissue, the apparatus comprising: a back frame; a plotter supported by the back frame for generating a microfiber structure; an electrospinning unit supported by the back frame and adjacent to the plotter along a first direction for spinning nanofiber in an internal space or on a surface of the microfiber structure to form a nanofiber web; a collection table for reciprocating below a lower portion of the plotter and below the lower portion of the electrospinning unit along the first direction to allow the microfiber structure to be formed on the collection table by the plotter and allow the nanofiber web to be formed on the collection table by the electrospinning unit; a first guide rail allowing the collection table to be mounted thereon and guiding the collection table mounted thereon to reciprocate along the first direction: and a second guide rail having the first guide rail mounted thereon for guiding the first guide rail along a second direction that crosses the first direction.
