| dc.description.abstract | The present study presents a novel screw-based continuous extrusion
bio 3D printing head, which has been specifically developed to improve the accuracy
and consistency of biofabrication processes. A thorough examination of the existing
literature reveals the constraints associated with current bio 3D printing technologies,
prompting the proposal of a screw-based system as a potential solution to overcome
these limitations. The system demonstrates the ability to achieve uninterrupted
extrusion by effectively adjusting to different bio-ink formulations through meticulous
regulation of feeding flow rate, pressure, and extrusion diameter. Notwithstanding the
achievement in developing a bio-extrusion printing head capable of precisely and
consistently regulating pressure, we faced difficulties pertaining to ink stability, which
had an impact on the consistency of printing filaments. The identification of this
limitation is recognized as a primary area of interest for future research, with the
objective of enhancing the quality and consistency of printed layers. The results of our
study provide significant contributions to the understanding of 3D bioprinter nozzle
functionality. Additionally, they shed light on the potential progress and obstacles in
extrusion technology, emphasizing our dedication to further improving the capabilities
of bioprinting technology. | en_US |
