3D printing bone platform

Abstract

The invention discloses a 3D printing bone platform and belongs to the field of 3D printing. The 3D printing bone platform comprises an upper bracket and a lower bracket which are movably connected with each other, wherein the upper bracket is of square shape; the bottom of the lower bracket is of square shape; the lower bracket comprises four support rods along the vertical direction; the vertex of the upper bracket is connected with the vertex of the bottom of the lower bracket through the support rods; the support rods are moveably connected with the upper bracket; the upper bracket can be overturned around the joint point; a print head is arranged on the upper bracket; a fusing device is fixedly arranged above the lower bracket; the fusing device is connected with the print head through a sampling pipe. The 3D printing bone platform provided by the invention has excellent biocompatibility and can supply growth cavity to the tissue cells; the print bone transplanted into the biological body can survive and be integrally fused with the transplant receptor; the printing precision is ultrahigh; the platform can correct at any time and accurately control the flow, so that the artificial bone completely matched with the original bone system can be acquired.

Description

technical field [0001] The invention relates to a printing platform, in particular to a 3D printing bone platform. Background technique [0002] Traditional bone repair or replacement methods include autologous bone grafting, allogeneic bone grafting, and bone lengthening, but these processes are time-consuming. With the development of science and technology, emerging bone tissue engineering scaffolds can replace traditional bone damage repair and replacement methods, and quickly perform bone repair. The preparation of existing bone tissue engineering scaffolds usually adopts solution casting / ion elution method, in situ forming method, electrospinning method, phase separation / lyophilization method, gas pore forming method, etc. These preparation methods have obtained comparative results. Satisfactory results, but unsatisfactory in terms of accuracy, pore uniformity, spatial structure complexity, and bracket customization. Although 3D printing of bones is possible with exis...

Problems solved by technology

The preparation of existing bone tissue engineering scaffolds usually adopts solution casting / ion elution method, in situ forming method, electrospinning method, phase separation / lyophilization method, gas pore forming method, etc. These preparation methods have obtained comparative results. Satisfactory results, but unsatisfactory in terms of accuracy, uniformity of pores, complexity of spatial structure, individualization of scaffolds, etc.

Although 3D printing of bones can be realized by existing technologies, due to the limitation of materials, the biocompatibility of artificial bones is poor, and the printing accuracy is slightly lower, which cannot perfectly fit with the original bone system.
