In an apparatus for manufacturing a hybrid scaffold, a first strand having bin compatible polymer and a second strand having a mixture of bio compatible material and cells alternate with each other. Thus, mechanical strength of the hybrid scaffold is improved, and the cells uniformly grow among entire region of the scaffold. Furthermore, diameters of the first and second strands and interval between the first and second strands are precisely controlled. Thus, the hybrid scaffold is precisely manufactured according to a scaffold design.
