This article presents a comprehensive analysis of polyamide 6 (PA6) and 12 (PA12) composites fabricated using additive manufacturing technologies such as Selective Laser Sintering (SLS) Multi Jet Fusion (MJF). It focuses on the mechanical properties, preparation processes, influence technological parameters final material characteristics. PA6 is characterized by higher degree crystallinity, contributing to its strength resistance high temperatures, whereas PA12 exhibits more amorphous structure, offering better dimensional stability lower moisture absorption. The examines these properties their implications for use in various applications. Applications span wide range industries, including automotive, aerospace, electronics, where they provide combination strength, wear resistance, chemical stability. Mechanical tensile toughness, are analyzed within context modern with MJF technology delivering homogeneous compared traditional methods. process involves optimizing temperature, cooling rates, layering, which significantly impact applicability composites.

This study aimed to investigate the potential of antimony-doped tin oxide (ATO) as a reinforcing agent for polyamide 12 (PA12) in 3D printing by examining four mixtures with varying ATO concentrations (2.0 8.0 wt.%, 2.0 wt.% interval). These were used fabricate filaments manufacturing specimens through material extrusion method. The mechanical properties resulting PA12/ATO composites and PA12 pure samples evaluated tensile, Charpy impact, flexural, microhardness tests. Additionally, rheology, structure, morphology, thermal properties, pore size, consistency dimensions evaluated. Thermogravimetric analysis, along differential scanning calorimetry, electron microscopy, energy-dispersive Raman spectroscopy, micro-computed tomography, conducted. results correlated interpreted. greatest reinforcement was achieved 4.0 mixture, which exhibited 19.3% increase tensile strength an 18.6% flexural compared (the control samples). impact also improved more than 10%. findings indicate merit additive manufacturing, particularly production components performance.

Additive manufacturing of polymer composites, also known as 3D printing, is one the progressive technologies in material engineering. It enables production parts with complex geometries while optimizing efficiency. Polylactide (PLA) a widely used additive due to its biodegradability and suitable mechanical properties. However, brittleness limited thermal stability require further modifications, such modifying filler structure or adding reinforcing materials. This paper focuses on analyzing influence different densities properties PLA manufactured by fused filament deposition (FFF) method. Three basic structures—cubic, gyroid rectilinear—were investigated at density levels from 20%, 40%, 60% 80%. Experimental tests were performed according ASTM D638 determine strength characteristics material. In addition tests, dynamic analysis (DMA) thermogravimetric (TG) better understand filling geometry viscoelastic behavior showed that higher improves At 80% filling, tensile reached 21.06 MPa (cubic), 20.53 (gyroid) 20.84 (linear). The elastic modulus was highest cubic (1414.19 MPa). yield 15.59 15.52 14.30
