The Impact of Additive Manufacturing on Supply Chain Management from a System Dynamics Model—Scenario: Traditional, Centralized, and Distributed Supply Chain

et al. 2022

In order to describe the impact that the appropriation of additive manufacturing (AM) has on the supply chain (SC), a validated system dynamics model representing vectorially multiple products and multiple demands in different periods was used as a basis to apply to a case study of medical implant manufacturing, configuring three chain scenarios: 1. traditional supply chain with subtractive manufacturing, 2. centralized supply chain with additive manufacturing, and 3. decentralized supply chain with additive manufacturing. It was possible to notice that the production time is longer in additive manufacturing compared to traditional manufacturing and the cycle time and total demand closure were lower in traditional manufacturing. In addition, it was observed that the AM performance is significantly better in conditions of lower demand, which can be attributed to the characteristics of customization and small batches that this type of production approach implies.

“…The intersection point is an initial condition, which indicates that both planes of triangular facets are intersected with their counterparts. The intersection point (P int ) of two lines in the 3D environment is defined by evaluating two points on the test facets P 1 and P 2 , and two corresponding shifted point distances d 1…”

“…This technology can also be used in bone reduction to physically generate the repositioned parts and evaluate the results of bone reduction. Several studies have reported that 3D-printed models can be held, examined, and manipulated by clinicians, much like the actual patient anatomy, to improve the safety and efficiency of surgery training and education [1][2][3][4]. Orthopedic 3D-printed models have been demonstrated to enhance the communication between the clinician and patient and improve the understanding of anatomy and pathology [5][6][7].…”

“…First, the quality of each bone model should be maximized. As the digitized bone model is extracted from CT images, some issues on the digitized model should be investigated, such as existing internal meshes due to cancellous bone [1,14], surface roughness due to image noise [23,24], and the accuracy of the STL model [25,26]. Second, in bone reduction, overlapping meshes may occur between two assembled bones [2,15,27].…”

Development of Mesh-Defect Removal Algorithm to Enhance the Fitting of 3D-Printed Parts for Comminuted Bone Fractures

et al. 2019

View full text Add to dashboard Cite

Purpose Mesh self-intersection defects and image noise may prevent 3D model reconstruction and mesh formation of bones with comminuted fractures, making it impossible to assemble 3D-printed fragments perfectly. This study proposes an algorithm to remove overlapping meshes and to smooth fracture surfaces in order to fabricate well-assembled 3D-printed bone. Methods 3D bone reconstruction, segmentation, and reduction were directly performed for three different classes of clinical fracture cases: pelvic 62-B1, 62-C2, and femur 31-A2.2. In contrast to the current Boolean operation, the proposed algorithm is not only capable of detecting overlapping meshes, but also recognizing the contact regions and detecting the boundary of each contact region. Hence, it was implemented in order to remove overlapping meshes and ensure that fragments fit together when physically assembled. Both gap distance and overlapping mesh errors during assembly of the 3D model from printed bone fragments were calculated and analyzed. Results and Conclusions Based on the comparison of results between the bone model before and after removing mesh defects, the RMS error is less than 0.33 mm and gap error is 3 mm, indicating that the proposed technique has high potential for eliminating mesh defects and providing a 3D-printed bone fracture model that is easy to assemble and disassemble.

Advanced Manufacturing of Patient‐Specific Occluders for the Left Atrial Appendage with Minimally Invasive Delivery

et al. 2020

View full text Add to dashboard Cite

A novel method for the rapid prototyping of personalized inflatable left atrial appendage occluders, suitable for minimally invasive delivery, is demonstrated. The method allows for the design, fabrication, and quantitative testing of implants based on an individual's computed tomography (CT) scan. The performance of a left atrial appendage occluder by characterizing its ability to anchor, prevent leaks, and not obstruct the left atrium is reported on. The design of the occluder by varying features such as size, inflation fluids, and surface patterns is optimized. The implant, and its delivery via a minimally invasive catheter, is demonstrated in a 3D‐printed left atrial model. Herein, the way for leveraging advanced manufacturing and imaging technologies for the development of personalized intracardiac implants for transcatheter delivery is described.
