Description

technical field [0001] The invention relates to the technical field of bio-ink 3D printing process parameter optimization, in particular to a method for optimizing process parameters of bio-ink 3D printing plane solid figures. Background technique [0002] Bioinks are defined as mixture gels containing biological components or biomaterials, generally processed by 3D printing. In recent years, bioinks prepared from plant components (cellulose, lignin, etc.) benefit from the advantages of low price, non-toxic and harmless, sustainable, sufficient sources, and good mechanical properties. The extensive attention of the industry has been successfully applied to medical fields such as tissue culture and rehabilitation engineering, as well as industrial fields such as batteries, sensors, and memory materials. The wide application of bio-inks puts forward high requirements for the optimization of process parameters of bio-ink 3D printing. The setting of bio-ink 3D printing process...

AI Technical Summary

Problems solved by technology

[0003] However, the current process research on bio-ink 3D printing has only focused on determining the printable parameter range of bio-ink 3D printing through experiments.

The existing method of determining the printable parameter range of bio-ink 3D printing through experiments can only provide an optional range of bio-ink 3D printing process parameters rather than a clear combination of optimized parameters, resulting in a solid plane of bio-ink 3D printing. Graphics quality varies and is difficult to achieve optimal quality

Therefore, in practical engineering applications, there is still a lack of a convenient, fast, accurate, and reliable process parameter optimization method for 3D printing of flat solid graphics with bio-inks.
