Abstract
Abstract. This paper describes the Charter on the preservation of the digital heritage and it also presents the five main printing technologies, FDM (Fused Deposition Modeling), SLA (Stereo Lithography Apparatus), DLP (Digital Light Processing), LCD (Liquid Crystal Display) and SLS (selective laser sintering) technology. Besides, It presents a methodology to process the restoration of a porcelain bowl through three-dimensional scanning and FDM (Fused Deposition Modeling) and LCD (Liquid Crystal Display) 3D printing technologies. First, the porcelain bowl is scanned with the scanner. Then the modeling software is used to reconstruct the missing part that the bowl presents. Finally, the reconstructed 3D fragment model is printed, completed and chromatically reintegrated. In order to optimize this restoration method to achieve the best visual effect similar to the appearance of the porcelain bowl, different printing materials are used for testing. This type of restoration method can improve the final appearance of the intervened area, minimize the operation of the object and can also make it be shaped quickly and precisely.
