The State Administration of Cultural Heritage released the progress of the major project "Archaeological China". More than 500 important cultural relics such as golden mask fragments, giant bronze masks, bronze sacred trees, and ivory were unearthed in the six sacrificial pits newly discovered at the Sanxingdui site in Guanghan, Sichuan. During this excavation in Sanxingdui, 3D printing + silicone film coating was used for the first time in the extraction of cultural relics, which is a major innovation in the archaeological community.
In the new phase of the archaeological excavation work in Sanxingdui, "Black Technology" 3D printing technology uses a 3D scanner to collect cultural relics and their surrounding information and data, and then prints exactly the same plaster model through a 3D printer. The printed plaster model was used to make a tightly fitted and protective silicone protective cover. After the protective cover was attached to the cultural relics, the cultural relics were extracted using a box.
The 3D printing protective cover is better than the film and soft cloth, because it is sticky, it has the best protective effect on the big bronze statue.
According to experts, this is the first time that 3D printing technology has been used for the extraction of cultural relics in the domestic archaeology session, and it is an innovative way. Because the cultural relics of Sanxingdui have been buried underground for more than 3,000 years, the cultural relics are relatively fragile and will be damaged if you are not careful. And the same person extracted this time, plus the filling inside, weighs about 1,000 kilograms, and you need to be more careful when extracting it.
In the past, cultural relics were extracted by wrapping plastic films and soft cloths, while silica gel film can better fit the surface of cultural relics. Moreover, silica gel itself has a certain viscosity and can be better attached to the surface of cultural relics. Can provide better protection.
