The purpose of this paper is to characterize three-dimensional (3D) printing filaments commonly used in fused deposition modeling (FDM) to determine their viability for restoration and conservation treatments.Design/methodology/approachEight current filaments for FDM from six polymeric materials have been characterized to determine their suitability for restoration and conservation treatments. For testing these filaments, specimens are printed with acrylonitrile-butadiene-styrene; polylactic acid; polylactic acid with CaCO3 (E.P.); polyethylene terephthalate glycol; polypropylene; and high-impact polystyrene. Suitability of a filament was verified using the Oddy test by detecting the action of volatile pollutants released from the filaments. The morphological and color changes were observed after allowing them to degrade under the exposure of UV radiation. The samples were then analyzed using Fourier-transform infrared spectroscopy. In addition, gas chromatography-mass spectroscopy technique was applied to complete the characterization of the printed filaments.FindingsMaterials investigated are suitable for restoration purposes ensuring long-term stability. Rapid prototyping using FDM is appropriate for restoring sensitive archaeological objects allowing reconstruction of parts and decreasing risk while manipulating delicate artifacts.Originality/valueRapid prototyping using FDM was chosen for the restoration of a fragile and sensitive archaeological glass bowl from Manises Ceramic Museum.
