Construction, automobile, the fields such as aerospace, dentistry and medical industries.And biological 3D printing be using 3D printing it is discrete/accumulation molding
Basic principle and method, to biomaterial (including natural biologic material and synthetic polymer) or cell suspending liquid into
The controlled printing of row, forms required biologically active implantation material, cell three-dimensional structure or artificial organ organ etc..3D gives birth to
Object printer, which is one kind, positioning assembly biomaterial or cell according to increasing material manufacturing principle under digital three-dimensional model driving
Unit manufactures the equipment of medical instrument, tissue engineering bracket and organizer official rank product.For biological 3D printer, beat
Print nozzle is the critical component for realizing printing function.For biomaterial 3D printing, the space of operation object is accurately controlled
Position and distribution, to realizing that biomaterial printing is of great significance.For the material with functionally gradient, such as
The consecutive variations that component is where realized in print procedure, are the deciding factors for realizing its function.Former using two kinds or more
When the mixed raw material of material is printed, due to there are raw materials used the case where being not suitable for mixing in advance, how to ensure that print head is defeated
The uniformity of the mixed raw material gone out is also a urgent problem to be solved.In utility model patent ZL201621441764.5
It is recorded, the raw material in different barrels is added in feeding pipe respectively, then by mixed biomass composite into
Row printing, it is difficult to ensure the uniformity of the constituent of biomass composite, and the additional proportion of different material is also difficult to
Control.
