“…Among the materials used for AM polymers have become a main center of interest for a wide range of applications, in addition to metals [16] and ceramics [17]. Versatility and synthetic adaptability have made polymers the most used for AM processes [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. Fused deposition modeling (FDM) or so-called fused filament fabrication (FFF) is one of the most popular AM processes due to its simplicity.…”

Rheology is proposed as a tool to explore plasticized poly(vinyl chloride) (PVC) formulations to be used in the fused filament fabrication (FFF) 3D printing process and so manufactures flexible and ductile objects by this technique. The viscoelastic origin of success/failure in FFF of these materials is investigated. The analysis of buckling of the filament is based on the ratio between compression modulus and viscosity, but for a correct approach the viscosity should be obtained under the conditions established in the nozzle. As demonstrated by small amplitude oscillatory shear (SAOS) measurements, PVC formulations have a crystallites network that provokes clogging in the nozzle. This network restricts printing conditions, because only vanishes at high temperatures, at which thermal degradation is triggered. It is observed that the analysis of the relaxation modulus G(t) is more performing than the G″/G′ ratio to get conclusions on the quality of layers welding. Models printed according to the established conditions show an excellent appearance and flexibility, marking a milestone in the route to obtain flexible objects by FFF.

“…Third, manufacturing preparation time can be substantially reduced, as the part is directly fabricated from its 3D model. These unique capabilities of AM technologies have brought great application potentials in several major industries such as aerospace (Angrish, 2014) and medical implants manufacturers (Jardini et al, 2014). For example, in the aerospace industry, lightweight, strong and sometimes electrically conductive parts are more desired.…”

Purpose -This paper aims to provide a comprehensive review of the state-of-the-art design methods for additive manufacturing (AM) technologies to improve functional performance. Design/methodology/approach -In this survey, design methods for AM to improve functional performance are divided into two main groups. They are design methods for a specific objective and general design methods. Design methods in the first group primarily focus on the improvement of functional performance, while the second group also takes other important factors such as manufacturability and cost into consideration with a more general framework. Design methods in each groups are carefully reviewed with discussion and comparison. Findings -The advantages and disadvantages of different design methods for AM are discussed in this paper. Some general issues of existing methods are summarized below: most existing design methods only focus on a single design scale with a single function; few product-level design methods are available for both products' functionality and assembly; and some existing design methods are hard to implement for the lack of suitable computer-aided design software. Practical implications -This study is a useful source for designers to select an appropriate design method to take full advantage of AM. Originality/value -In this survey, a novel classification method is used to categorize existing design methods for AM. Based on this classification method, a comprehensive review is provided in this paper as an informative source for designers and researchers working in this field.

“…The most popular polymer-based AM processes used in aerospace applications include SLA, FDM, and Jet type processes such as polyjet, etc. It is observed from the research undertaken that parts made using SLA are sturdier than the ones made using FDM and therefore SLA based products are best suited for casting purposes in the aerospace industry [ 179 ]. The aerospace industries require parts made of materials with lower weight and high strength, which is possible using AM and can be manufactured on demand.…”

The use of additive manufacturing (AM) has moved well beyond prototyping and has been established as a highly versatile manufacturing method with demonstrated potential to completely transform traditional manufacturing in the future. In this paper, a comprehensive review and critical analyses of the recent advances and achievements in the field of different AM processes for polymers, their composites and nanocomposites, elastomers and multi materials, shape memory polymers and thermo-responsive materials are presented. Moreover, their applications in different fields such as bio-medical, electronics, textiles, and aerospace industries are also discussed. We conclude the article with an account of further research needs and future perspectives of AM process with polymeric materials.
