## 1 Introduction
The raster orientation's effects on axial loading fatigue life have been studied by [PERSON] et al. [45; 46; 47]. According to the research, the 45\({}^{\circ}\)/45\({}^{\circ}\) raster orientation performed the best. As previously stated, FFF 3D printing involves a staggeringly high number of process variables [46; 47; 48; 49], and all of them could have an effect on the end part's mechanical characteristics [48]. Several studies have revealed numerous variables that may potentially alter the 3D-printed objects' mechanical properties and fatigue life [50; 51; 52; 53]. The mechanical characteristics and dimensional accuracy of the FFF parts are extensively reported [54; 55; 56]. Polyamides (polymers with amide bonds connecting the monomeric units), can be sourced from nature, such as proteins, while synthetic polyamides also exist, such as polycaprolactam (Polyamide 6--PA6) and poly(hexamethylene aligmamide) (Polyamide 6.6--PA6.6) [57]. Similar to polyesters, polyamides can be divided into three groups based on the main chain's chemical makeup: aliphatic, semi-aromatic, and aromatic polyamides [58]. Among these, polyamide 6 (PA6) has emerged as one of the plastics for engineering with a significant variety of uses due to its reasonable price, strong heat resistance, and good processing qualities [59; 60; 61; 62]. As expected, it has been employed in 3D printing applications, and its performance has been investigated and reported [63]. Fur thermore, the use of polyamide 6 (PA6) as a practical matrix material in lightweight carbon fiber-reinforced, graphene nanoplatelet-reinforced, or reinforcing fibers of cement mortars is increasing [64; 65; 66; 67; 68]. Its mechanical performance under tensile and fatigue loadings in 3D printing has been thoroughly studied [69; 70; 71; 72; 73; 74; 75]. [PERSON] et al. [48] performed a fatigue investigation focused on the viscoelastic response of PA6 in FFF 3D printing. Flexural tests were conducted, and the porosity and surface roughness were also assessed. The sustainability of polyamides in 3D printing has also been investigated through their ability to be reused after multiple thermomechanical processes during their recycling process [76]. Research in polyamides in FFF extends also to the process parameters' effect on composites having polyamides as the matrix material. Ceramics, such as Titanium Nitride (TiN), Copper (Cu), and Cuprous Oxide (Cu\({}_{2}\)O), have been introduced to polyamide matrices [77; 78], as has Zirconium Dioxide (ZrO\({}_{2}\)) [79]. In this direction, [PERSON] et al. [59] have investigated PA6/Carbon fiber composites. The outcome of the research supported the impact of these variables on the bonding formation during the FFF method and the mechanical responses of the printed items. In addition, [PERSON] et al. [80] investigated the effects of eight FFF parameters on the characteristics of PA6/PA6 composite samples using the Taguchi technique. Based on the results of their study, it was found that samples with infill patterns with a zigzag configuration and a layer thickness of 0.15 mm showed greater surface quality, dimensional accuracy, and mechanical performance. The compressive strength of FFF items has, however, received scant attention in the literature [19]. Even though compression loading is a relatively typical loading type, in-depth research on material reactions to compression loads is rarely the focus of research [81]. Furthermore, no study has yet shown the power requirements for 3D printed PA6 polymer components or how the 3D printing settings employed for the particular polymer influence the amount of energy needed to build the parts, despite the PA6 polymer's outstanding performance for sustainable applications. In this study, Polyamide 6 was used as the material to examine the impact of seven general control factors as well as the energy and mechanical response during the compressive response of MEX 3D printed samples.
