Medical biological 3D printing device

Abstract

The invention discloses a medical biological 3D printing device. During printing, a printing material can be quickly replaced; during replacement, quick connection can be achieved only by moving a print head assembly and then matching the feeding end of the print head assembly with a discharging head of a needed printing raw material tank; when replacement of the printing raw material is needed, rapid combination with the needed printing raw material can be achieved only by electrically connecting two contacting conductive control sheets with two fixed conductive sheets at the corresponding printing raw material tank for 2-3 seconds at the same time; the matching precision is high, the replacement rate of the printing material can be greatly increased, and the printing accuracy can be improved; and in addition, through constant temperature control of the printing material, shape change after printing is reduced and the printing accuracy is improved.

Description

Technical field [0001] The invention relates to a medical biology 3D printing device, belonging to the technical field of medical 3D printing auxiliary equipment. Background technique [0002] 3D printing technology is based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. 3D printers appeared in the mid-1990s as a rapid prototyping device using technologies such as light curing and paper lamination. It is basically the same as a normal printer. The printer contains liquid or powder and other "printing materials". After connecting to the computer, the "printing materials" are superimposed layer by layer through computer control, and the blueprint on the computer is finally turned into a real object. 3D printing technology can better help solve patient problems. For example, in orthopedics, the bone contour can be printed and shaped by a scanning device, and in dentistry, the entire interior of t...

Problems solved by technology

[0003] When printing a medical 3D printing device, since the medical structure is often complex in structure, the requirements for each position of the structure are different, and each part of the medical structure is often printed with different materials. The current 3D printing head is generally only It can realize the printing of a single material. In this way, when printing different parts, it is necessary to replace different print heads, and it is very inconvenient to replace the print head. After replacement, it needs to be recalibrated. In the subsequent printing, it is easy to appear that the printing accuracy cannot be achieved. More difficult to achieve fast and efficient printing
