Eclectic architecture has several elements called ornaments, which have a high geometric complexity and bring questions about its documentation and restoration. Those ornaments are made from different types of materials which needs different solutions when using new technologies to produce their copies. This work focuses on techniques for restoration of metal eclectic ornaments. Photogrammetry is used for documentation and capture of the 3D model of the geometric composition of cultural heritage buildings elements to be used in the restoration project. With the digital models, digital fabrication techniques are applied as support to intervention projects and restoration of metal ornaments. Tests are performed in 3D printing and CNC machine for production of a wax piece to be used in the casting process. Finally the techniques are compared indicating their advantages and disadvantages.
