Development of reversible intelligent prosthesis for the conservation of sculptures. A case study

“…6). According to theoretical model [38], magnets placed in opposite magnetic configurations reduce the magnetic field thus closing the magnetic flux.…”

“…An SLA Form2 stereolithographic printer (Formlabs) with a resolution range of 25-100 μm of layer thickness, UV laser of 250 mW and 140 μm for printing the prosthesis was used. NdFeB magnets were selected with a Ni / Cu / Ni coating with magnetization in the axial direction (Supermagnete) and acrylic resin Paraloid B72 (50% w/v in acetone) (Rohm and Haas) to join the prosthesis with magnetic systems to the surface of the tomb [38][39]. VXelements (Creaform), Zbrush (Pixologic) and Preform (FormLabs) software were used for data processing, processing, 3D modeling and prosthesis printing, respectively.…”

“…Finally, the prosthesis with the sensors adhered with magnetic systems in the area of the tomb. Taking as reference the theoretical model developed by Rodríguez, et al [38][39] and, having the prosthesis as a whole weighing approximately 130 g, the magnetic force required was 1.27N. For this, four pairs of magnets model S-02-02-N (Supermagnete) were used, each of which provided a force of 1.47 N, according to the manufacturer's specifications, and placed in opposite magnetic configurations to reduce the magnetic field thus closing the magnetic flux.…”
