Description

Technical Field

[0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing device for a breast prosthesis mold. Background Art

[0002] Prosthetic breasts, also known as silicone prosthetic breasts or surgical breasts, are special rehabilitation products after breast cancer surgery. They have a certain load-bearing capacity and play a role in maintaining body balance, compensating for postoperative physical defects, maintaining the beauty of female body, enhancing self-confidence in life, and protecting the fragile chest cavity.

[0003] One of the methods currently used is to make prosthetic breasts by 3D printing molds. For example, in the prior art, a Chinese invention patent application with application publication number CN105877879A discloses a method for making customized prosthetic breasts by 3D printing molds, which requires building a three-dimensional model of the prosthetic breast, then making a prosthetic breast mold by 3D printing, and finally pouring the prosthetic breast material into the prosthetic breast mold, and obtaining a customized prosthetic breast after curing and molding.

[0004] During the mold printing process, the print head generates a lot of heat, which accumulates in the 3D printer device, which is not conducive to the cooling and solidification of the printed product, and is prone to collapse, affecting the printing quality. The Chinese utility model patent document with the authorization announcement number CN221717842U discloses a bionic 3D printing equipment cooling device, which blows the airflow directly to the surface of the printed product through the exhaust ring. The airflow will cause the printed product to deform and collapse, affecting the accuracy of the mold.

[0005] Therefore, it is necessary to design a 3D printing device for breast prosthesis molds that can accelerate mold curing and molding, shorten the production cycle of breast prosthesis molds, and ensure the printing accuracy of the molds to solve the current technical problems.

[0037] In some embodiments, a limit plate 76 is provided on the end of the screw rod 75 facing away from the adjusting motor 77. The limit plate 76 is a circular plate structure with a diameter larger than that of the screw rod 75. The limit plate 76 and the screw rod 75 are concentrically fixedly connected to form an integral structure. The limiting function of the limit plate 76 can prevent the connecting seat 74 from slipping off the screw rod 75 during the adjustment process.
