Multi-nozzle real-time protection printing module for portable biological 3D printer

Abstract

The invention discloses a multi-nozzle real-time protection printing module for a portable biological 3D printer. The multi-nozzle real-time protection printing module comprises a replaceable multi-nozzle system, a real-time power-off protection system and an extrusion type power system. Due to the replaceable multi-nozzle system, it can be ensured that the positions of nozzles are fixed, the extrusion type power system drives a screw rod to conduct transmission through a stepping motor and a gearbox, and the screw rod extrudes materials in a liquid injection bin for printing. By means of the real-time power-off protection system, a switch of an electromagnet can be used for making a printing needle and the screw rod rebound in time at the moment of the power failure so as to prevent a printing face from being damaged. Thus, by means of the device, fast replacement of printing materials can be conducted in a portable human body 3D printing device, and protection for preventing secondary traumas can be conducted on wounds.

Description

technical field [0001] The patent of the present invention relates to the field of 3D printer nozzle structure design, especially a multi-nozzle instant protection printing module of a portable biological 3D printer. Background technique [0002] 3D printing technology was proposed in the 1980s, also known as "rapid prototyping technology". Traditional 3D printing projects are widely used because they can print objects directly from computer-designed graphics or areas without machining or grinding tools, thereby shortening the product development cycle, improving production efficiency and reducing production costs. art or industry. With the development of technology, it has been widely used in digital model product manufacturing, bionic medicine, aerospace and other fields. The 3D printers currently on the market are printed by dividing into several different filling areas and different nozzles. When the nozzles are blocked, they cannot be used normally, which affects work...

AI Technical Summary

Problems solved by technology

However, most of the existing printers with replaceable nozzles on the market are disc-type replacement nozzle devices. The device covers a large area and requires a large space in daily conditions, which does not meet the requirements of portability.

This type of printer uses a large number of synchronous belt drives. As time goes by, the synchronous belt is prone to hazards such as surface wear or bending failure, which affects the accuracy of printed products.
