The latest developments in three-dimensional printing technology both in terms of equipment and materials offer a new opportunity in the microsurgical treatment of intracranial aneurysms. 3D printed model of the patient’s aneurysms enables optimal anatomical visualization with personalized preoperative planning. This is a retrospective study of a series of 16 patients suffering from ruptured intracranial aneurysms, admitted and microsurgical treated based on rapid 3D printed models to our clinic from September 2016 to March 2018. We analyzed the dates concerning patient demographics, clinical, surgical technique and outcomes correlated with the data of the 3D-printed replica used for planning emergency surgeries.

“…Anatomical modeling: Using the criteria built into the simulation for querying the DICOM data, most of the bone tissue was separated from the patient's other tissues [32][33][34]. In this study, Mimics is used to construct 2D images and create a 3D CAD model to reconstruct unique implants comprising encapsulated soft tissues and bone structure.…”

In medical surgery, a customized implant is often required to meet surgical requirements, especially in cases with complicated or traumatic deformities. The emerging techniques of additive manufacturing, e.g., 3D printing, may help provide a quick response to such needs, provided that a valid approach capturing required implant shape data is generated and processed to better suit 3D printing. Different materials, including biocompatible polymer and metal, may suit medical-surgical applications. In this paper, an investigation is conducted to assess 3D printing technology use as part of a full system, from capturing implant shape data to producing the customized implant. The investigation is supported by experimental studies of medical cases. The first case aimed to produce shatter-related finger distal phalanx implants, whereas the second aimed to design and reconstruct a suitable cranial implant for a patient with a left frontoparietal skull lesion. For these cases, the study has adopted a scenario based on CT scans to generate the required implant shape data; hence using DICOM format. The captured data from the two cases are processed using a developed systematic processing approach to generate the final design of the required customized implants. The designs are then converted into suitable manufacturing codes for 3D printed plastic and metal prototypes enabling the assessment of the technique utilizing the facilities of UrukTech Company in Baghdad, Iraq, and Sohar University in Oman. Results show that the developed approach, from data capture to 3D printed implants, has succeeded in addressing the need for customized implants. For instance, the accuracy of the cranial implant was confirmed dimensionally, aiding in restoring structures, appearance, and psychological stability. The design and manufacturing of custom 3D-printed bone implants represent a significant advancement in medical technology and orthopedics, provided that biocompatible materials are used. Therefore, the technique may be adopted in the near future to serve the medical surgery field. The developed approach in this study encompasses several key ideas, contributions, and significant results, including creating patient-specific bone implants by utilizing medical imaging and 3D printing. Hence, the developed approach enables the creation of complex implant geometries that otherwise would be challenging to manufacture.

“…The possibility of additive shaping and the defined positioning of specific dimples and bumps, or the assessment of the components of joints or solids of revolution, are particularly important issues. Additive technologies can be adapted to manufacture a wide array of component types for use in the automotive industry [39][40][41][42], medical industry [43,44], foundry industry [45,46] or pneumatic and hydraulic industries [47]. The key issue here is to take into account the technological parameters of the manufacturing process, as they directly translate to the quality of the components obtained [48][49][50].…”

The article assesses the impact of data treatment on the possibility of assessing the morphological features of additively manufactured spherical surfaces. Tests were carried out on specimens manufactured by PBF-LB/M additive technology, using titanium-powder-based material (Ti6Al4V). The surface topography was assessed using one of the multiscale methods—wavelet transformation. The tests carried out on a wide spectrum of mother wavelet forms emphasized the occurrence of characteristic morphological features on the surface of the tested specimens. Moreover, the significance of the impact of specific metrology operations, measurement data processing and its parameters on the filtration result were noted. Comprehensive assessment of additively manufactured spherical surfaces with simultaneous analysis of the impact of measurement data processing is a novelty and fills a research gap relating to comprehensive surface diagnostics. The research contributes to the development of modern diagnostic systems allowing for a fast and comprehensive assessment of surface topography, taking into account the various stages of data analysis.
