Problems solved by technology

Generally, the temperature control of the existing nozzles often cannot realize the temperature control of the end of the needle, and the needle clogging will often be caused by this. Realizing the temperature control of the needle tip can better solve the problem of needle clogging

Abstract

The invention provides a two-section independent temperature-control biological 3D printing spray nozzle. The two-section independent temperature-control biological 3D printing spray nozzle comprisesa main shell, a material barrel, a spraying nozzle extruding device and a spraying nozzle needle, a first temperature-control device is arranged in the main shell, the material barrel is inserted intothe first temperature-control device, and the bottom end of the material barrel is connected with the spraying nozzle extruding device through a feeding pipe. A discharging pipe is arranged at the bottom end of the spraying nozzle extruding device, the spraying nozzle needle is connected with the discharging pipe and penetrates out to the outer side of the bottom of the main shell, a second temperature-control device is arranged between the tail end of the spraying nozzle needle and the top end of the discharging pipe, and a heat isolating device for preventing mutual interference of the temperatures is arranged between the first temperature-control device and the second temperature-control device. According to the two-section independent temperature-control biological 3D printing spray nozzle, independent temperature control over the spraying nozzle material barrel section and the spraying nozzle needle section is achieved, gradient temperature control of the spraying nozzle can be achieved, all gradient values are mutually independent, and temperature control is not affected by one another.

Description

technical field [0001] The present invention relates to the technical field of 3D printing equipment, and more specifically, to a two-section independent temperature-controlled biological 3D printing nozzle. Background technique [0002] Bio-3D printing refers to the technology of bio-manufacturing by using bio-materials or cells with good biocompatibility and with the help of multi-dimensional printers and other equipment with complex shaping movements. Among them, biological materials or cells are directly in contact with the printing nozzle of the printer, and are gathered on the forming platform of the printer through the extrusion or injection of the nozzle to obtain the required scaffold and tissue organ model. In this process, the nozzle of the printer plays a key role. In addition to meeting the basic biological requirements, the printing nozzle also needs to perform printing temperature pretreatment on biological materials or cells, that is, to provide an appropriat...
