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 experimentally determining the range of printable parameters of bio-ink 3D printing can only provide an optional range of bio-ink 3D printing process parameters rather than a clear combination of optimized parameters, resulting in linear elements of bio-ink 3D printing Quality varies and it 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 linear elements with bio-inks

Abstract

The invention discloses a bio-ink 3D printing straight line element process parameter optimization method, which comprises the following steps: S1, determining process parameters influencing the bio-ink 3D printing straight line element effect by analyzing a 3D printing process; S2, defining a size error of a bio-ink 3D printing straight line element and a measurement method of the bio-ink 3D printing straight line element; S3, obtaining a printable range of each process parameter through a screening test; S4, determining a Taguchi method orthogonal test table through an interaction test; S5, completing a Taguchi method orthogonal test, and performing signal-to-noise ratio analysis on a size error to obtain an optimal process parameter. According to the process parameter optimization method, the optimal process parameter combination can be conveniently, quickly, accurately and reliably obtained when different bio-inks and / or extrusion type 3D printers are tried to carry out bio-ink 3D linear element printing.

Description

technical field [0001] The invention relates to the technical field of bio-ink 3D printing, in particular to a process parameter optimization method for bio-ink 3D printing linear elements. 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 parameters plays a vital role in the...
