THE USE OF 3D-SCANNING AND ADDITIVE TECHNOLOGIES FOR DOCUMENTATION AND CREATING PHYSICAL COPIES OF PRINTS FROM THE COLLECTION OF SPBF ARAN

The paper describes the creation of a 3D archive and physical copies of prints. A way of restoring prints is pro-posed, based on creation of a special matrix that is obtained by a combined use of 3D scanning technology and additive technologies. Print sampling was performed using an optical 3D-scanner operating on the basis of structured light. The technique of computer processing, necessary for loading the 3D model, obtained as a result of 3D-scanning, into the 3D-printer microprocessor is discussed in detail. The creation of a print replica and a restoration matrix was performed by using the laser 3D printers employing the technology of laser stereolithog-raphy. The print reproducing accuracy was estimated by comparing its 3D model with 3D model of the replica. The experiments proved the basic capability of creating 3D archives and prints reproducing.
