Abstract: The present invention relates to a method for producing an artificial scalp model using a 3D printing-based multi-point multi-nozzles, and an artificial scalp model manufactured by using same, in which a dermal mimetic body can be created by using a plurality of nozzle arrays, a pore mimic structure can be generated, and hair follicle spheroids can then be created by 3D printing. In the method for producing an artificial scalp model using a 3D printing-based multi-point multi-nozzles and the artificial scalp model manufactured by using same, according to the present invention, by mimicking the hair of a healthy scalp, a plurality of arrayed hair follicle cells can be generated by 3D printing, and by using this, the effect of maximizing the treatment effect of scarring alopecia is obtained.

Abstract: The present invention relates to a method for producing an adipose model through environmental control and an adipose model created using same, the method comprising the steps of: providing a first bioink, which is cell-unfriendly; creating a bath suspension with a predetermined volume by using the first bioink; providing a second bioink comprising preadipocytes; 3Dprinting the second bioink in the bath suspension so as to produce an adipose model; and culturing the bath suspension in which the adipose model is disposed. The method for producing an adipose model through environmental control and the adipose model created using same, according to the present disclosure, form environments for a 3D-printed adipose model, and limit the proliferation area of adipose cells and induce the differentiation thereof, and thus can maximize similarity with actual adipose tissues.

Abstract: The present invention relates to a bellows framework having a concave-convex structure on at least one of outer and inner sides using three-dimensional printing technology and a method of producing thereof, and an artificial tracheal replacement comprising an epithelium part formed on the inner side of the bellows framework and an annular cartilage part formed along the circumference of concave-convex grooves on the outer side and a method of producing thereof.
