3D printer and resin facial model

In the event of death in accidents and other incidents, the remains often have serious defects. The funeral home can only be repaired by traditional materials such as sludge and wax. The operation time is long and the fidelity is poor.

On March 30th, the first studio in the country to use 3D printing technology for body restoration was formally established in Shanghai Longhua Funeral Parlour. The studio will use the 3D printing technology to repair the damaged remains partially or in whole. This technology has been incorporated into the 13th Five-Year Plan of the Civil Affairs Bureau of Shanghai.

Liu Fengming, manager of the funeral department of Shanghai Funeral Service Center, told the reporter () that due to technical restrictions, in the past, traditional clay materials could only be used for restoration, which can only roughly restore the shape of the face of the body. Lack of real skin and hair texture.

In order to overcome the bottleneck problem of traditional body repair, Shanghai Funeral Service Center organized Shanghai's cosmetic experts to tackle the problem and decided to use 3D printing body repair technology to meet the needs of special remains such as martyrs, so that the body can be oriented with the best face. another world.

Liu Fengming told the journalist that 3D printing technology is based on computer three-dimensional digital imaging technology, which uses layered processing and superposition molding to increase the material layer by layer to generate 3D entities. Therefore, the technology can produce entities of arbitrary complex geometries, greatly reducing the manufacturing difficulty of complex products. The vast majority of bodies that have died due to disasters, car accidents, and industrial accidents have a wide range of bone damage, heavy damage, large defects, and difficult recovery. Using 3D bone structure reconstruction technology, the damaged bone can be restored by computer scanning measurement, achieving high-precision replication effect, implanting the damaged part, thereby improving the success rate of the body repair.

More powerfully, through a powerful computer model database, a three-dimensional human face physical model can be created from a 2D image. 3D printing body repair studio combines 3D printing technology with traditional body repair technology, using wound scanning, computer 3D modeling, 3D printing, implanting hair, makeup surface modification and other technologies to reproduce the body appearance and repair similarity up to 95 %the above.

澎湃The reporter saw at the scene that the technician first simulated the realistic 3D graphics on the computer according to the photos of the deceased, and then the 3D printer started working, using the white resin material to play the facial contour of the deceased, just like a realistic mask.

Human body parts printed with white resin material

According to Liu Fengming, the color of the resin material is relatively simple, and it is usually placed on the face of the body in the transport of the body, so as to fill the intermediate space with antiseptic drugs and isolate the air. Face models made with flammable powders can simulate realistic skin tones and hair, and come alive.

Liu Fengming said that the best material from the hand is photosensitive silica gel, which is only 1.2 mm thick and feels as elastic as the skin of the human body. However, because the cost of silicone materials is as high as 10,000 yuan, and the color of the skin cannot be reached temporarily, the first widely used ones will be flammable powder materials. The cost of a facial model is about four or five thousand yuan.

Liu Fengming used his own model as a model to print his own head using 3D printing technology. The realistic level scared everyone. He said that with the continuous development of printing materials, it is possible to develop from solid materials such as metals, plastics, polymer materials and ceramics to liquid, gel and cell hybrid materials.

It is envisaged that the development of computer 3D technology in the field of body repair of the funeral industry will certainly promote the wide application of this technology in other fields of the funeral industry. For example, the 3D printing portrait technology can replace the future in the farewell meeting. After the portrait, the 3D portrait can be transplanted to the tombstone of the cemetery. With the development of 3D information technology, it is possible to combine the acousto-optic technology to produce the holographic projection image of the deceased, and to read the farewell by personally reminiscing on the farewell or multimedia platform.

On March 30th, the first life spar studio in China was officially listed in Shanghai Yishan Funeral Parlour. Six new internationally patented ashes and petrochemicals were introduced from Korea to refine the ashes into powder and use ultra-high temperature. It becomes a spar-like ball. An ashes can form more than a hundred spars.

Liu Fengming said that the production of a life spar is currently priced at 17,900 yuan, and a 20% discount during trial operation. Compared with the cemetery, the funeral burden of the public can be greatly reduced. Previously, a survey conducted by the Shanghai Entrusted Service Center earlier found that 50% of the respondents indicated that they could accept the life spar, but 20% of the respondents clearly indicated that they could not accept it and would choose the traditional ashes to enter the burial style.
