“…Typically, the printing orientation plays a decisive role in mechanical properties, lead time, accuracy, surface texture, and consumption of raw materials. 37 In this study, the printing orientation did not affect the machining characteristics of AM Al-based composite. Thus, optimizing the input conditions following an adequate approach before machining the composite was required to attain and maintain the desired machining characteristics irrespective of the composite's printing orientation.…”

Understanding the machinability of additively manufactured composite materials is crucial for efficient manufacturing. The study aimed to evaluate the machinability of the composite material (AlSi10Mg + Niobium carbide (NbC)) using the Electro-discharge machining (EDM) process and to investigate the influence of different printing orientations on the EDM process. The Plackett–Burman design was initially employed to determine the significant EDM parameters. Subsequently, the Box–Behnken Design was followed to obtain the optimal settings on the EDM setup. The validation experiment based on the composite desirability approach confirmed the maximum material removal rate (MRRmax) and minimum tool wear rate (TWRmin). The identified configuration of 3 wt. % NbC reinforcement in AlSi10Mg, printed in the 0° orientation, exhibited the best performance in MRRmax: 146.43 mg/min, TWRmin: 0.00072 mg/min, and surface finish of 2.813 µm. These findings enhance the understanding of composite machinability and can assist in optimizing the EDM process for advanced materials.

“…59 Some authors have suggested that surgical templates should be submerged in 70% ethanol for a minimum of 15 min or undergo sterilization using ethylene oxide gas to avoid deformation. 61 Storage of surgical templates prior to surgery has also been studied and the use of wet-dry storage for no more than 30 days has demonstrated the best results in terms of reducing inaccuracies 62 (Figure 9).…”

ObjectiveTo provide technical and clinical recommendations for implementing a digital workflow in Static Computer‐Aided Implant Surgery in the anterior maxilla.Clinical ConsiderationsAn optimal 3D implant position is crucial for achieving satisfying results in implant rehabilitation in the esthetic area. Due to its complexity, implant placement in the esthetic zone should be executed with precision and predictability. Static Computer‐Aided Implant Surgery requires thorough planning and detailed attention to every step of the digital workflow protocol.ConclusionsImplant positioning in the esthetic zone using Static Computer‐Aided Implant Surgery is a technique‐sensitive procedure that requires precise execution of each step. This approach ensures accurate prosthetically driven 3D implant placement and prevents potential errors that could lead to inaccurate positioning.Clinical SignificanceThe proper implementation of Static Computer‐Aided Implant Surgery may increase the level of agreement between the planned and definitive implant 3D positions in the esthetic zone, thus enhancing the esthetic outcomes of implant rehabilitation.

“…It is imperative to note that the design of devices used in this type of production can have a substantial impact on the quality of the resulting products [12]. Characteristics of these devices, such as the motion control system of the print head or platform in the XYZ axes, the material deposition method, and the control system, can significantly influence the surface and mechanical properties of the manufactured products [13]. These factors can provide advantages in the production of specific types of products [14].…”

The objective of this study is to compare the quality of 3D printed models manufactured using the Fused Filament Fabrication (FFF) method. The samples were fabricated using a robotic arm with 4 axes and conventional 3D printers. The focus of this experiment lies in assessing the influence of the devices’ structural design on the resulting quality of the 3D printed models. Additionally, the study aims to identify the strengths and limitations of each device and define their respective applicability. The 3D model designed for this investigation comprises intricate geometrical shapes specifically chosen to evaluate the precision and repeatability of layer deposition while establishing geometric tolerances and determining shape deviations. The samples were 3D printed under identical printing conditions and parameters, and subsequently, these produced samples will undergo 3D digitization through an optical scanner, namely ATOS II Triple Scan. The obtained data will then be subjected to a comparative analysis utilizing GOM Inspect software to determine the geometric tolerances. The findings from this analysis will be critically evaluated and serve as a basis for informing and guiding future research endeavors.
