Abstract
Mayo Clinic’s Division of Engineering (DOE) has a long history of innovation in medical device design and manufacturing, dating back to the establishment of its Instrument Shop in 1915. In 2006, Mayo Clinic began using additive manufacturing (AM), to assist physicians on clinical cases. The DOE's first additive machine was purchased in 2007, and today the Additive Manufacturing Facility (AMF) owns a number of printers for both polymer and metal fabrication. The AMF is run by Mechanical Engineering Design Technicians and its capabilities are utilized broadly by engineers and designers alike. Fabrication requests are organized using a Manufacturing Execution System (MES), which is paramount to the successful operation and reporting on all AM work. In the context of medical device development work, the system can be used to manage the inventory of raw materials and finished goods, schedule print jobs, track the progress of print jobs, monitor the performance of machines, and generate reports on production and quality.
DOEs MES plays a critical role in the successful operation of its AMF. The system is used to manage all aspects of the AM process, from scheduling print jobs to tracking the progress and delivery of those jobs. This allows the AMF to ensure that all requests are completed on time and to a high standard of quality. Mayo Clinic's experience with an MES demonstrates the value of these systems for AM, namely increased throughput, improved quality, reduced costs, and increased visibility into the additive manufacturing process.

Abstract
Additive Manufacturing of patient-specific metal implants can provide personalized solutions for challenging conditions. The recent advancements in Designing for Additive Manufacturing (DfAM) such as lattice generation features, real-time simulation tools, generative design, and interactive optimization enable designers to rapidly generate designs of patient-specific implants. The clinical process has to be fast but is complicated by regulatory requirements and the interaction of multiple disciplines from radiology to surgery. The radiology produces Digital Imaging and Communications in Medicine (DICOM) files that need to be segmented, visualized in 3D, and converted to faceted models. The surgeon needs to communicate the surgical plan such as slice planes, locking devices, implant type, pore size for osseointegration, overall porosity, material, etc. The designer needs to use the doctor's guidelines, the faceted model, generative design, lattice generation features, structural simulation, and DfAM rules to optimize the implant design. The manufacturer needs to evaluate the design and the suggested print orientation for printability and post-processing. The surgical team needs to evaluate the quality of the implant and practice the surgical plan using the printed implant and its adjacent components. Finally, the surgical team performs the operation. In this presentation, the design process of an award-winning femur implant with gyroid lattices will be demonstrated. The automatic generation of a solid model from the faceted date will be presented. The thickness of the gyroid infill is functionally graded based on the attachment surfaces and the simulation results. The current barriers in the process will also be outlined. The vision of how to overcome these barriers with the use of Artificial Intelligence (AI) in segmentation and Augmented and Virtual reality (AR/VR) in surgical planning will be presented.

Abstract
Over 1.2 million people in the U.S. are projected to suffer from Parkinson’s Disease by 2030. Current therapies on the market offer pharmaceuticals and surgically placed medical devices, such as deep brain stimulators, that only address symptoms of Parkinson’s disease but still have a market valuation of $700 million. Tissue transplantation in patients with Parkinson’s Disease to replace lost dopaminergic neurons of the substantia nigra pars compacta has been studied since the 1980s [1-3]. However, there are many problems with such treatments resulting from inadequate stem cell (specifically, autologous induced pluripotent stem cell (iPSC)) isolation, culture, and insertion procedures, specifically in the implantation of stem cells into patient-derived midbrain dopaminergic progenitor cells. Although such cells can be easily extracted from numerous sources for Parkinson’s Disease treatment, it is the stem cell delivery method that has proven problematic, with only 30% viable after delivery [4]. This is because the stem cells grown in culture before insertion are typically removed from cell culture plates using harsh chemicals (like trypsin) which disrupts cell to cell contacts, reverses intended differentiation, and overall can lead to cell death. Further, stem cells have been shown to migrate away from the areas of the brain in which they were implanted, migrating away from damaged tissue in which they are needed for repair [5]. A biomaterial delivery device and “anchor” for viable stem cells would go a long way in treating numerous neurological diseases, such as Parkinson’s Disease.

Abstract
In the craniomaxillofacial sector, the custom made approach is gaining a lot of interest, mainly by additive manufacturing technologies, allowing to ensure lower infection/inflammation risk, reduced morbidity, shorter surgery times, higher aesthetical results, better correspondence between the produced implant and the graft site [1,2].
In order to overcome the currently evidenced limits, i.e. the post surgery inflammation reaction occurrence and the osteointegration lack [3], graded scaffold were designed, produced by fused deposition modelling (FDM) technique, and properly functionalized.
FDM printing of selected biopolymers (i.e., polylactid acid (PLA), polymethylmethacrylate (PMMA), polycaprolactone (PCL)) was properly set up, in terms of extrusion and bed temperatures, printing speed and flow [4]. Seven different pattern depositions (i.e. Line, Grid, Gyroids, Concentric, Octet, Triangle, Zig-Zag) were tested. The obtained structures were coated with osteonintegrative materials and loaded with suitably selected antibiotic/anti-inflammatory agents. The produced systems were characerised by scanning electron microscopy (SEM), infrared spectroscopy (FTIR/ATR), X-ray diffraction (XRD), release kinetics tests, differential scanning calorimetry (DSC), tensile and compression tests. The cytotoxicity was assessed by MTT assay, and osteoblastic differentiation capability evaluated by in vitro cell tests with preosteoblasts. Functionalised scaffolds were successfully produced by FDM, coated with osteointegrative materials and loaded with antibiotic/anti-inflammatory agents. The efficacy of the coating and loading protocols was validated. The no cytotoxicity of all the studied systems was demonstrated, as well as their capability to promote the osteoblastic differentiation [5].Line pattern provided the best mechanical behavior, whereas the different deposition patterns did not significantly affect the biological responsiveness.

Abstract
Over the last decade, there have been attempts to introduce additive manufacturing into the training of seafarers. At the heart of this was the hope that spare parts would be manufactured on site (on board ships) when there are needed. However, this idea could potentially work in a laboratory environment. In practice, many aspects are not yet covered. For example, vibrations caused by the ship’s engines or the ship’s movements can affect the printed sprat part. If the 3D printing process is successful, the problem of degradation of the material properties and the influence of the aggressive maritime environment arises. This could be exacerbated by additional aggressive materials in the engine room.
Another aspect that has been considered is maritime applications, where there are no problems with vibrations, for example, as is the case with offshore applications. However, 3D printing in this case shortens the supply chain, but the delivery could be almost the same as for regular spare parts.
In conclusion, we point out that all the required properties of filaments must be met in the complex maritime environment and that there is a need for new filaments for these applications.

Abstract
The high-pressure condition encountered inside hydrogen storage vessel of type 4 [1] imposes to study the degradation of composite material under static pressure. In the present work we expose a promising method. We proposed a coupled approach between finite element method (FEM) and machine learning (ML). The representative volume element (RVE) was used to generate the law behaviour and the damage law [2] as an input data. Algorithms for ML such classification K-nearest neighbours (k-NN) and a special k-NN with dynamic time warping (DTW) [3], were employed to classify the degree of degradation for each RVE. The hierarchical clustering through dendrograms [4] allowed to extract knowledge in term of fiber, matrix properties and fibers’ volume fraction sensitivity to different solicitations. Strain ductile degradation obtained from computation, is forecasted as a time’s series by artificial neural networks [5].

Abstract
This presentation focuses on the latest advancements in additive manufacturing techniques for the production of medical implants using magnesium alloys. Magnesium alloys have gained significant attention in the field of implant manufacturing due to their biocompatibility, lightweight nature, and mechanical strength. However, there are challenges that need to be addressed to fully exploit their potential. The first trend discussed is topological optimization, where advanced algorithms are used to design complex implant structures that optimize load distribution and minimize material usage. Integration into the design and manufacturing processes, as well as validation of optimized designs, present challenges in this area. The second trend focuses on enhancing the material properties of magnesium alloys. Precise control of microstructure and composition is vital to improve mechanical strength, biocompatibility, and corrosion resistance. Achieving a balance between these properties while maintaining cost- effective manufacturing techniques poses a challenge. Customized design and fabrication is another important trend, allowing implants to be tailored to fit the unique anatomy of each patient. Optimization of the design process for customization, cost-effectiveness, and regulatory compliance presents challenges in this area. Lastly, the emerging trend of tissue and organ bio- printing using magnesium alloys opens new possibilities in regenerative medicine. Developing bioinks compatible with magnesium alloys and achieving precise bio-printing of complex structures are challenges to be overcome. Addressing these challenges will unlock the full potential of magnesium alloys in medical implant manufacturing. By combining topological optimization, material enhancements, customized design, and tissue bio-printing, we can revolutionize the field, offering personalized implants with improved biocompatibility and functionality.

Abstract
Wire arc additive manufacturing (WAAM) is increasingly gaining favor over other additive manufacturing processes, particularly for producing large-scale components. The microstructural changes during the solidification process in WAAM are influenced by the heat input and layering sequence. In this study, Inconel alloy was utilized for WAAM deposition with various layering sequences using GMAW to investigate their impact on grain growth, microstructure, and mechanical properties. Diverse layering sequences were devised to prevent the formation of columnar grains resulting from oscillation beads and multiple passes in a single layer. The unidirectional heat conduction encourages grain growth from the bottom to the top, connecting grains at fusion boundaries. Nucleation and epitaxial grain growth are likely to occur at the fusion border between the previously solidified bead and liquid metal. Consequently, the transverse columnar grains are influenced by the grain size of the preceding layer. While a traditional stacking sequence in one direction yields columnar grains, a zigzag layering sequence refines grain growth. The zigzag sequence disrupts the heat conduction and grain development direction, resulting in smaller fragmented grains that enhance isotropic characteristics. The anisotropic behavior of additively manufactured deposits is shown to be dependent on grain growth direction and size, influenced by the layering sequence. WAAM deposits with a zigzag layering sequence exhibited superior hardness and tensile strength compared to standard layering methods. Additionally, the zigzag layering sequence enhances the resolution of deposited walls with a linear shape.

Abstract
This presentation focuses on The Transformative Impact of Additive Manufacturing on Product Life Cycles.
Additive Manufacturing (AM), often referred to as 3D printing, has a profound impact on the product life cycle. This innovative technology disrupts traditional manufacturing processes at every stage, from conception to disposal.
In the conceptualization and design phase, AM accelerates product development by enabling rapid prototyping and iterative design changes. This minimizes time and costs while promoting innovation through the creation of complex, customized geometries.
Manufacturing and production benefit from AM's ability to produce complex and highly customized components without the need for expensive tooling. This opens up possibilities for small-scale and on-demand manufacturing, reducing waste and enhancing supply chain efficiency.
AM also transforms the supply chain and distribution phase by allowing for distributed and localized production. Digital inventories and on-demand manufacturing reduce inventory costs and waste, making the process more sustainable.
Maintenance and repair become more accessible with AM, as replacement parts can be produced quickly and cost-effectively. This extends the life of products, reducing the environmental impact associated with premature disposal.
Lastly, AM supports sustainability by promoting the recycling of end-of-life products and encouraging the design of eco-friendly, efficient components. AM is reshaping the product life cycle by making it more agile, efficient, and environmentally friendly, paving the way for a future of innovation and sustainable manufacturing.

Abstract
In vitro platforms, such as lab-on-chip, tissue-on-chip, 3D cell culturing, etc. find applications in multiple domains (personalized medicine, tissue engineering, pharmaceutical studies, in vitro diagnostic, etc.). These platforms are usually conceived as a multilayer/multifunctional 3D devices integrating, in the order, a substrate, a microfluidic layer, an electrical interface and a biological scaffold. Fabrication is possibly succeeded by cell culturing with patient derived cells to reach personalized solutions.
Manufacturing of such devices requires the use of advanced technologies with functional integration and multimaterial capabilities. In this context, it is believed that aerosol jet-based printing (AJP) can be considered as the next key enabling technology to reach this purpose. AJP stands out for its capability to print a wide variety of materials, including electrically conductive inks, biological solutions, hydrogels, UV resins, etc., at micrometric resolution and on free-from substrates (e.g. flexible, rigid, flat and/or 3D shaped supports). It has proven ability in the domain of printed electronics and its application as 3D printing technology for 3D bioelectronics interfaces and (collagen) scaffolds is under investigation.
In this contribution, recent trends in aerosol jet printing are reviewed and its potential as enabling technology to develop integrated in vitro devices for diagnostic and personalized treatments is critically discussed. The focus is given on the work conducted at the KU Leuven, Advanced Manufacturing Laboratory (AML), with respect to 3D microstructuring, bioelectrical applications along with biocompatibility study of commercial inks, and high-resolution collagen AJ printing.

Abstract
Metal powders manufactured by inert gas atomization, provide consistent quality & high performance raw materials for many of the different additive manufacturing processes, especially Powder Bed Fusion. New alloys have been developed in recent years for many different industries, including Super Austenitic Stainless Steels specifically designed for the marine, oil & gas and chemical industries with material properties that include high toughness & corrosion resistance, as well as high-temperature creep resistance. And Super Duplex 2507 stainless steel, printed by Powder Bed Fusion – Laser Beam (PBF-LB) and heat treated to create superior corrosion resistance & mechanical performance compared to that of wrought material. Maraging steels, including 18NI300 and the ultra-high hardness grade (MAR-60) benefit from in-situ heat treatment when deposited by Direct Energy Deposition (DED) and are therefore particularly suited to repair and refurbishment of damaged or worn components. Cobalt free maraging steels provide a sustainable solution with equivalent performance in terms of hardness to that of established materials, such as 18NI300/M300, typically used for mould tooling applications. A new Hot Work Tool (HWT) steel has been developed, with a modified composition compared to H13 for mould tooling & aluminium die casting applications, that prints without cracking without powder bed heating. New metal powder product developments presented include extending the range of copper alloys for PBF-LB, relevant to space technology specifically rocket nozzle applications, based on Cu-Cr-Zr (C18150) and more recently Cu-Cr-Nb, specifically GRcop42 as developed by NASA.
