## 1 Introduction
This layer-by-layer solidification process is repeated until the entire product is finished. Following the printing, an additional UV light exposure is often required to ensure full solidification [19]. Three-dimensionally-printed objects can undergo UV curing to enhance the solidification process [20]. UV exposure prompts the creation of additional chemical bonds, enhancing the resin's mechanical strength and stability. Parameters like temperature, wavelength, and curing time used during the process impact the ultimate properties [20]. Additionally, this curing method can enhance product homogeneity. SLA technology allows for exceptionally precise printing with high resolution, meaning that printed products are highly detailed and have smooth surfaces. There is a wide range of different materials that can be used in SLA printing, including transparent, solid, flexible, engineering, and even medical resins (biocompatible resins, dental resins, etc.). In this study, FDM and SLA printers were used to manufacture ABS and ABS-like specimens for mechanical testing. ABS is a copolymer that exhibits a unique chemical composition composed of three primary monomers: acrylonitrile (15% to 35%), butadiene (5% to 30%), and styrene (40% to 60%) [24; 25; 26]. Each of these monomers contributes distinct properties to the polymer, which collectively result in ABS's exceptional characteristics. Based on the review of the scientific literature [27; 28; 29; 30; 31; 32; 33; 34; 35; 36; 37; 38; 39; 40; 41; 42; 43; 44; 45; 46], it can be concluded that the mechanical properties of FDM 3D-printed ABS polymer materials have been explored from various perspectives, such as the impacts of the raster angle [31; 32; 33; 34], layer thickness [35; 36; 37; 38; 39; 40; 41], infill percentage [38; 39; 40; 41], printing speed [42; 43; 44], etc. In the paper [38], [PERSON] et al. examined how varying infill percentages impacted the mechanical strength and production costs of 3D-printed ABS components. They conducted experiments with infill percentages set at 50%, 75%, and 100%. Their findings revealed that components created with 100% infill consistently exhibited superior mechanical properties when compared to those with 50% infill. [PERSON] et al. [39] explore the effects of infill density, material density, and extrusion temperature on the mechanical characteristics of ABS, PETG, and multi-material samples produced through FDM printing in their study. They create multi-material specimens by alternately layering 50% ABS and 50% PETG using FDM 3D printing. The researchers emphasize that the ultimate tensile strength (UTS) experiences a 20% increase when the infill proportion is raised from 20% to 60%. [PERSON] et al. [40] investigated how various printing parameters, such as the infill percentage, affect the mechanical properties of ABS printed using FDM. They also developed a mathematical model for the numerical prediction of these properties, employing response surface methodology. Their research showed notable enhancements in both tensile strength and Young's modulus correlating with an increase in infill percentage. In the paper [41], the authors determined that raising the infill percentage from 20% to 50% in ABS results in a 26% enhancement in ultimate tensile strength (UTS), a 24% increase in yield stress, a 45% boost in Young's modulus, and a slight 1% improvement in elongation at break. ABS-like resin is part of the group of thermoplastic polymers consisting of three components: acrylonitrile, butadiene, and styrene [47; 48; 49; 50; 51; 52; 53]. As reported in [49], the presence of acrylonitrile enhances the thermal and chemical resilience, along with the surface hardness of the end product. Meanwhile, butadiene plays a crucial role in augmenting the toughness and impact resistance, whereas styrene is instrumental in improving processability, rigidity, and the overall strength of the material. ABS-like resins are well-suited for 3D printing components that require moderate detailing, high durability, and adequate functionality [50].
