Purpose

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/approach

Eight 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.

Findings

Materials 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/value

Rapid prototyping using FDM was chosen for the restoration of a fragile and sensitive archaeological glass bowl from Manises Ceramic Museum.

使用快速原型制作修复敏感考古物体的 3D 打印细丝的表征

目的

本文的目的是表征熔融沉积建模 (FDM) 中常用的三维 (3D) 打印细丝,以确定它们在修复和保护处理中的可行性。

设计/方法/方法

来自六种聚合物材料的八种当前用于 FDM 的细丝已被表征,以确定它们对修复和保护处理的适用性。为了测试这些长丝,样品上印有丙烯腈-丁二烯-苯乙烯;聚乳酸;含 CaCO3 (EP) 的聚乳酸;聚对苯二甲酸乙二醇酯;聚丙烯; 和高抗冲聚苯乙烯。通过检测从长丝释放的挥发性污染物的作用,使用 Oddy 测试验证长丝的适用性。在使它们在紫外线辐射下降解后观察到形态和颜色的变化。然后使用傅立叶变换红外光谱分析样品。此外,还应用气相色谱-质谱技术来完成打印丝的表征。

发现

研究的材料适用于修复目的,确保长期稳定性。使用 FDM 的快速原型制作适用于恢复敏感的考古对象,允许重建部件并降低风险,同时处理精致的文物。

原创性/价值

选择使用 FDM 进行快速原型制作来修复来自 Manises 陶瓷博物馆的脆弱而敏感的考古玻璃碗。
