“…Using an unsuitable adhesive thus would lead to catastrophic failure of structures, which can and should be avoided. Furthermore, the study by Unuk, et al [5] has revealed that under elevated temperatures, the performance of adhesives may be altered and this becomes a point of consideration for particular applications which require operations under higher temperatures or are stored under elevated temperatures. To the best of the authors' knowledge, whilst adhesive tests have been extensively studied for polymers or composites fabricated by the traditional molding and subtractive manufacturing methods, for instance, Hall, et al [6] investigated the adhesive bonding on polymers such as polyethylene, polypropylene, polystyrene and nylon 6 while Awaja, et al [7] reviewed the adhesive bonding for general polymers in terms of adhesion mechanisms, promoters and measurement techniques, there is very limited literature on recommendations for adhesives suitable for various FDM printed plastic materials, with the exception of a general study of various adhesive behaviors on the 3D printed material investigated by Espalin, et al [4].…”
