“…Further, Jo et al (2018) mentioned that controlling layer thickness, external heat, and pressure helped in reducing the void in the internal structure of the printed object and creating an object of better finish and improved mechanical properties. Similarly, (Rajpurohit and Dave, 2018) studied the effect of raster angle, layer height, and raster width on the tensile properties of FDM printed PLA parts where they found the highest tensile strength at 0 • raster angle. Those samples that had lower layer height exhibited higher tensile strength because of the larger bonding area.…”

Three-dimensional (3D) printing is a revolutionary manufacturing technique that can fabricate a 3D object by depositing materials layer by layer. Different materials such as metals, polymers, and concretes are generally used for 3D printing. In order to make 3D printing sustainable, researchers are working on the use of different bioderived materials for 3D printing. Because of the abundant and sustainable sources, and versatile properties, biomaterials are considered as the potential candidates that have the ability to replace petroleum-based polymers. This review highlights the basic overview of fused deposition modeling (FDM) technique of 3D printing and recent developments that have occurred on FDM printing using biomaterials. Specifically, FDM printing process, final properties, and characteristics of biopolymers, their composites, and polymers containing biofillers are discussed.

“…Except for infill configurations conventionally analyzed in other research works, we aimed to investigate the configuration applied in the manufacturing of filament-wound pipes, which provides them the exceptional mechanical properties [13]. In most of the previous works, which investigate a similar topic of the raster angle, specimens were printed only in one direction without corresponding interlayer orientated in the right angle to the previous one, hence layers were deposited perpendicularly [14,15]. Noticeably fewer research works were related to investigations of the varying angle between alternating layers [16], and, to the best of our knowledge, no work has been published, in which 55' • configuration was analyzed, which have been repeatedly proven to provide exceptional properties in the case of filament-wound pipes [17,18].…”

Due to the rapid growth of 3D printing popularity, including fused deposition modeling (FDM), as one of the most common technologies, the proper understanding of the process and influence of its parameters on resulting products is crucial for its development. One of the most crucial parameters of FDM printing is the raster angle and mutual arrangement of the following filament layers. Presented research work aims to evaluate different raster angles (45°, 55°, 55’°, 60° and 90°) on the static, as well as rarely investigated, dynamic mechanical properties of 3D printed acrylonitrile butadiene styrene (ABS) materials. Configuration named 55’° was based on the optimal winding angle in filament-wound pipes, which provides them exceptional mechanical performance and durability. Also in the case of 3D printed samples, it resulted in the best impact strength, comparing to other raster angles, despite relatively weaker tensile performance. Interestingly, all 3D printed samples showed surprisingly high values of impact strength considering their calculated brittleness, which provides new insights into understanding the mechanical performance of 3D printed structures. Simultaneously, it proves that, despite extensive research works related to FDM technology, there is still a lot of investigation required for a proper understanding of this process.

“…A regression model was developed for predicting the tensile and flexural strength of the components printed with these parameters. The process parameters of raster angle, layer height and raster width influence the strength; and the cross-sectional morphology captures the influence of print parameters in the specimen [38][39][40]. All these studies emphasised the importance of determining the directional properties of FDM prints.…”

Fused deposition modelling (FDM) is an additive manufacturing method having the potential to fabricate functional components. As the inherent nature of additive structures, the component stiffness depends on the build parameters such as layer height and raster orientation in addition to the filament material properties. Even on FDM prints with 100% infill density, voids are formed along the interface of rasters and contribute to the characteristics of the component. The primary role of the present work is to determine elastic characteristics such as Young's modulus, shear modulus and Poisson's ratio of FDM components and study the effect of build parameters. The void geometry identified from the cross-sectional morphology was used to create a microscale representative volume element (RVE) model capturing the characteristics of the FDM print. The elastic constants of the microscale model RVE were estimated by volume average method and homogenised over the entire structure. The study also investigated the influence of layer height on the elastic behaviour of FDM components in two different raster orientations of 0° and 0°/90°. Both the conditions exhibited directional characteristics and the elasticity constants approaches filament characteristics with decreases in the layer height. The modulus of elasticity was found maximum in the direction of raster orientation, whereas the elasticity modulus along vertical direction exhibited the lowest. The components with 0°-90° raster orientation exhibited transversely isotropic characteristics. Thus, the actual cross-sectional morphology-based microscale numerical analysis can effectively predict the directional attributes of FDM prints.
