“…In the case of the 0°configuration, considerable damage is observed for the Y specimen, which has the highest stiffness and where the Z direction is perpendicular to the loading direction. Specimens Y, as already observed in Zeybek et al (2023), show two perpendicular shear bands that drive the opening of a central crack (as shown in Figure 14). Specimens X show a deformation behaviour driven by the separation between layers, along the Z direction, but do not reach a failure condition.…”

“…Tests on specimens with different orientations in space provide valuable information on the dependence of elastic and plastic properties from relative orientation between material (X, Y and Z) and loading directions (z) (as shown in Figure 7), giving an insight into the characteristic anisotropy of printed materials (Guessasma et al, 2016;Zeybek et al, 2023). Also, the latter type of test increases the number of experimental information about the mechanical behaviour of the material, strengthening considerations and reliability of the trends observed.…”

“…In the case of fibrereinforced materials, the bonding between two distinct portions of material is particularly critical because of the presence of fibres in the matrix that enhance discontinuity and increase the viscosity (Zhang et al, 2018;Fallon et al, 2019). Many authors focused on the characterization of tensile properties with particular attention to the effects of material orientation and raster angle, observing a relevant influence of both parameters on the material's anisotropy (Zhao et al, 2019;Yao et al, 2020;Zouauoi et al, 2021;Bandinelli et al, 2023;Dudescu and Racz, 2017;Gonabadi et al, 2020;Guessasma et al, 2016;Kannan et al, 2020;Zeybek et al, 2023). Generally, tensile testing is the most used material characterization method to find the elastic modulus, yield and ultimate tensile strengths.…”

“…Athale et al (2022) focused on the characterization of PA12 with short carbon fibres, observing a neat difference between tensile and compression properties. Zeybek et al (2023) focused on PA6 with short carbon fibres, obtaining a dependency of compression properties on the strain rate of deformation. Among previous works, to the best of the authors' knowledge, only a few use compression properties of FFF materials to represent their compressive behaviour using finite element (FE) models (Athale et al, 2022;Guessasma et al, 2016;Song et al, 2017;Tabacu and Ducu, 2020;Corvi et al, 2023).…”

Purpose Finite element (FE) analysis can be used for both design and verification of components. In the case of 3D-printed materials, a proper characterization of properties, accounting for anisotropy and raster angles, can help develop efficient material models. This study aims to use compression tests to characterize short carbon-reinforced PA12 made by fused filament fabrication (FFF) and to model its behaviour by the FE method. Design/methodology/approach In this work, the authors focus on compression tests, using post-processed specimens to overcome external defects introduced by the FFF process. The material’s elastoplastic mechanical behaviour is modelled by an elastic stiffness matrix, Hill’s anisotropic yield criterion and Voce’s isotropic hardening law, considering the stacking sequence of raster angles. A FE analysis is conducted to reproduce the material’s compressive behaviour through the LS-DYNA software. Findings The proposed model can capture stress values at different deformation levels and peculiar aspects of deformed shapes until the onset of damage mechanisms. Deformation and damage mechanisms are strictly correlated to orientation and raster angle. Originality/value The paper aims to contribute to the understanding of 3D-printed material’s behaviour through compression tests on bulk 3D-printed material. The methodology proposed, enriched with an anisotropic damage criterion, could be effectively used for design and verification purposes in the field of 3D-printed components through FE analysis.

“…For the 3D printed parts [87], the deformation of the samples as shown under the microscope, evolves in a similar manner to the samples in the current study. Corresponding comparison results are derived for the 3D printed polyamide and polyamide composites [90][91][92], that occurs both within and between layers throughout the manufacturing process of these components [84].…”

Herein, a research and engineering gap, i.e., the quantitative determination of the effects of the compressive loading rate on the engineering response of the most popular polymers in Material Extrusion (MEX) Additive Manufacturing (AM) is successfully filled out. PLA (Polylactic Acid), ABS (Acrylonitrile Butadiene Styrene), PP (Polypropylene), and PA12 (Polyamide 12) raw powders were evaluated and melt-extruded to produce fully documented filaments for 3D printing. Compressive specimens after the ASTM-D695 standard were then fabricated with MEX AM. The compressive tests were carried out in pure quasi-static conditions of the test standard (1.3 mm/min) and in accelerated loading rates of 50, 100, 150, and 200 mm/min respectively per polymer. The experimental and evaluation course proved differences in engineering responses among different polymers, in terms of compressive strength, elasticity modulus, toughness, and strain rate sensitivity index. A common finding was that the increase in the strain rate increased the mechanical response of the polymeric parts. The increase in the compressive strength reached 25% between the lowest and the highest strain rates the parts were tested for most polymers. Remarkable variations of deformation and fracture modes were also observed and documented. The current research yielded results with valuable predictive capacity for modeling and engineering modeling, which hold engineering and industrial merit.

Nowadays, it is possible to produce products with complex geometries, thanks to the experts who have continuously explored the advancements in additive manufacturing (AM) techniques. This review helps readers understand the opportunities and difficulties associated with developing parts for various industries, including aerospace, tooling, electronics, and biomedicine. The present work describes the landscape of polymeric composites using laminated object manufacturing (LOM) and fused deposition modeling (FDM). This paper discusses recent publications in the realm of AM related to composite fabrication, materials, techniques, functionality, and future scope. The effects of nanofiller reinforcement on the mechanical properties of composites have been thoroughly investigated. Furthermore, FDM process parameters such as layer thickness, infill speed, nozzle temperature, and raster angle have also been considered. Finally, the challenges and potential applications of LOM and FDM of additively manufactured composites have been summarized.
