三次元造形装置は、意匠モデルやコンペ・展示会出展用モデルの作成に多く利用され、カラーモデル化が求められている。本研究では、ナイロン粉末焼結型RP造形品のカラーモデルの提供を目的に、RP基材に適した塗装および着色技術の開発を行った。前処理、塗料、塗装方法、塗装仕様と加工技術などの塗装適性の検討により、RP製品モデルに活用できる物性と塗装外観をもつ塗装工程の開発をした。塗装では、立体造形品をプロトタイプモデルとして有効に活用できる外観を実現することができた。

Lacquer called urushi, which is the only natural polymer produced in Asia, is polymerized by laccase to produce a beautiful coating. Recent studies have made it clear that urushi coating films are weak against ultraviolet irradiation and that exposure to ultraviolet rays could cause them to deteriorate. For example, flaking off of films, loss in gloss, or cracking might possibly occur. Restoration for conservation is, therefore, necessary for historic urushi objects. There are many experimental reports using a single-layer urushi coating film on a glass board, but there are few chemical research data of traditional restoration techniques using urushi. Therefore, in this study, samples of polished four-layer urushi coating films were first exposed to ultraviolet irradiation. Then the effect of restoration techniques for conservation was examined by applying two techniques, suri urushi and urushi gatame, on the deteriorated coating films. Through this study, it was verified that the appearance of the films changes differently with the two techniques. Suri urushi is suitable for adjusting the gloss, because gloss rises on the deteriorated films. Urushi gatame is suitable for restoration in general, because it suppresses changes of gloss and color in the restoration of cultural properties to a great degree. The results show that repair of and protection against deteriorated urushi coating films are possible by restoration techniques using urushi sap.
