The objective of this article is to examine the impacts molybdenum disulphide (MoS2) and graphite-filled (Gr) polyetheretherketone (PEEK) composites that have been fabricated through 3D printing on their mechanical properties crystallinity. Seven samples thirty-five dog bones were produced using different filament strands conduct analysis. Before extrusion into filaments, solid lubricants, MoS2, graphite uniformly dispersed within PEEK blending. At a concentration 10 wt.%, PEEK/MoS2 exhibited highest tensile strength, measuring approximately 104 MPa, while PEEK/Gr displayed lowest strength at same concentration, 36 MPa. In addition, demonstrated better elongation, 4.7%, compared composites, which 2.3% elongation. X-ray diffraction (XRD) data revealed neither MoS2 nor significantly interacted with matrix. degree crystallinity, as determined by density matrices, indicated printed possessed higher level 62% 5 than calculated values. This suggests filament-making processes had an annealing effect. significance lubricant content dispersion in shaping crystal formation 3D-printed emphasized study. Furthermore, research provides valuable insights for optimizing PEEK-based materials various applications.

Process parameter optimization and selection play a crucial role in additive manufacturing, particularly determining the quality characteristics of final product. Among these parameters, infill pattern holds significant importance as it directly influences structural integrity, production time, material usage efficiency printed object. This research focuses on identifying most suitable 3D printing process parameters for thermoplastic polyurethane (TPU) material, specifically applications pipeline construction. The criteria considered include ultimate tensile strength, flexural surface defect minimization. Various patterns, including hexagonal, line, solid, triangle (35°), (55°), line are evaluated alternatives. Utilizing multi‐criteria decision‐making technique known analytical hierarchy (AHP), systematic approach is employed to determine optimal pattern. findings this study reveal that hexagonal outperforms other selected patterns terms meeting set forth construction using TPU material. contributes enhancing manufacturing processes applications, emphasizing informed achieving desired performance outcomes.

Distal radius fractures (DRF) are one of the most prevalent injuries a person may sustain. The current treatment DRF involves use casts made from Plaster Paris or fiberglass. application these materials is serious endeavor that influences their intended use, and should be conducted by specially trained personnel. In this research, with full-body 3D scanner Vitus Smart, modelling software Rhinoceros 3D, printer Creality CR-10 max, an easy, yet effective workflow orthosis fabrication was developed. Furthermore, samples represent segments were subjected to static loading. Lastly, fragments occurred due excessive force characterized digital microscope. It observed implementation designed workflow, faster printing process present. Samples mechanical loading had values exceeded those conventional Paris; minimum recorded value 681 N, while highest 914 N. Microscopic characterization enabled clear insight into occurrence fragments, as well potential risk. Therefore, in different stages fabrication, undesirable events, risks they pose presented.
