23 Jul Print nozzle system and mixed spraying printing technology of adjustable soft hollow tube support
Abstract
The invention provides a print nozzle system and mixed spraying printing technology of an adjustable soft hollow tube support.The print nozzle system comprises five functional parts including a pneumatic power source, a feeding device, a mixing device, sprayers and a spraying device. A hollow circular pipe is formed in such a manner that a solution A is subjected to dispensing, mixing and spraying technology under effects of a solution B, a solution C and a solution D via the sprayers. A two-layer or multi-layer structure is constructed. Under the spraying effect, connection strength between/among layers can be increased. The print nozzle system and mixed spraying printing technology of the adjustable soft hollow tube have following beneficial effects: two solutions can be completely mixed; continuous structures of hollow or solid circular pipes can be printed and accumulated in order to form different structures in order to print and manufacture hollow circular pipes similar to blood vessels; a micro-channel structure in the interior of the support can be constructed in order to transfer nutrition and other substance in tissue engineering by repair of large tissue; and the print nozzle system and mixed spraying printing technology of the adjustable soft hollow tube can be extensively applied to construction of biological tissues in all kinds.
