23 Jul Forming system for tissue engineering bone and cartilage scaffold and biological 3D printing forming method
Abstract
The invention discloses a forming system for a tissue engineering bone and cartilage scaffold and a biological 3D printing forming method. The forming system comprises a spray head device, a three-dimensional motion mechanism, a forming table, a pressure source, a control system and a data processing system; on the basis of technical principle of pneumatic extrusion forming, motion of the three-dimensional motion mechanism and material supply of the spray head device are controlled by the control system and the data processing system, and two materials are extruded simultaneously by double parallel pin heads. According to the forming system and method for the tissue engineering bone and cartilage scaffold, control is easy, operation is simple, and a special composite graded scaffold can beprepared.
