The world of Archeology and History has always gotten along well with 3D Printing, thanks to being able to create low-cost replicas or the conservation of pieces with a 3D printer. Years ago a project was created consisting of digitizing monuments so that in the not too distant future they can be reproduced to our liking without having to be there or without waiting for the approval of political groups.
Now, it seems that future has come to us. Various Chinese students have succeeded in restoring and recreating historical buildings and monumentsall thanks to 3D printing.
It all started with the restoration of a frieze from the Huazhong University building. This restoration was done using the same 3D printing technology that is used in printing buildings or houses.
The restoration of monuments in China will depend on the materials that we have to use
Adapting that technology to the printer, the students followed the same plan as with normal 3D printing. First they scanned and digitized the object, then they looked and chose the material most similar to the object or restored part and after printing, the placement and adaptation of the new part.
This has been quite successful in Chinese historical buildings that were falling down but it will not be applicable to all desired historical monuments. Materials are still a problem and this is emphasized in the project. Some monuments cannot be restored due to materials and others will have to be chiselled after printing to give the original shape.
In any case, these techniques that China will use will be of great help to many localities and regions of Old Europe, since restorations are not as cheap and easy as the construction of these and it seems that China knows.
