Therefore, Zhang Changrong suggested that the friction coefficient is a major goal [China Packaging News] researchers from the research and development center of the nano biomaterial Laboratory of CONICET and cindefi at the National University of La Plata in Argentina are developing a 3D bioprinting system with a fourth axis. It is said that the printer will print more complex cylindrical, tubular or spiral structures

according to Sergio Katz, the chief researcher, traditional FDM 3D printing requires deposition of wires layer by layer, which cannot print complex and delicate shape structures. After seeing the limitations of plastic and biological 3D printing processes, they decided to develop a new method to print biological materials

their goal is to develop an additive manufacturing system, which can print biopolymers into shape, cylindrical or helical structures by using syringes with interchangeable nozzles

the traditional three pairs of high-frequency induction product D printer has only three axes: X, y and Z. As shown in the above figure, researchers added a fourth axis to their 3D printer as a rotating printing surface

using this printing method, researchers can program the syringe to move axially on the X axis, which means that the 3D printing material is deposited on a rotating cylindrical surface. The fourth axis can rotate clockwise or counterclockwise

in terms of materials, researchers have been exploring the use of various biopolymer mixtures, such as mixtures containing alginate, pectin, chitosan and hydrogels. These mixtures are being modified to achieve different mechanical properties; As well as being tested to clarify the error, we also look at its printing potential and biocompatibility

finally, researchers say that their new bioprinting method can help improve cell growth on biocompatible scaffolds through well-designed lattice and structure
