3D printing system for manufacturing human skeletons

Abstract

The invention provides a 3D printing system for manufacturing human skeletons. The 3D printing system comprises a laser device, a galvanometer connected to the laser device through an optical fiber, a heater for preheating, a worktable device with a forming area and a powder supply device used for supplying powder to the forming area, wherein the heater is arranged above the worktable device, and the powder supply device is arranged on one side of the worktable device. According to the 3D printing system for manufacturing the human skeletons, the SLM forming technology is adopted, and therefore the efficiency of manufacturing the human skeletons is improved, the steps are simplified, and the production cost is greatly lowered.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a 3D printing system for manufacturing human bones. Background technique [0002] When the artificial bone is implanted in the human body, it will contact different tissue cells: skin, loose subcutaneous connective, etc. If the tissue cells are firmly combined with the bone, the bone implanted in the patient can be used reliably for a long time. In order to achieve this goal, it is necessary to design from various aspects such as the material of the bone and the surface morphology of the bone. The porous structure can provide an ideal basis for the growth of human tissue, and the structure allows cells and tissues to enter the porous structure of the bone to form Tightly combined; according to clinical trials, the porous structure on the bone surface is not composed of structures in a single size range, but porous structures ranging from nanometers, submicrometers, micrometers, etc.; t...

In order to achieve this goal, it is necessary to design from various aspects such as the material of the bone and the surface morphology of the bone. The porous structure can provide an ideal basis for the growth of human tissue, and the structure allows cells and tissues to enter the porous structure of the bone to form Tightly combined; according to clinical trials, the porous structure on the bone surface is not composed of structures in a single size range, but porous structures ranging from nanometers, submicrometers, micrometers, etc.; traditional manufacturing processes are formed in tens of microns Structural features in the size range are feasible, but it is very difficult for structures in the micron and submicron size ranges. In order to manufacture micron and submicron structures, a variety of complex means are required, such as chemical etching, through chemical etching liquid The chemical reaction between the etched substance and the etching method to peel off the etched substance has defects such as unsatisfactory pattern etching fidelity, and difficulty in controlling the minimum line of the etched pattern.
