Additive manufacturing, specifically 3D printing, technology has revolutionized the design, creation, and building of parts and engineering objects. The fused deposition modeling (FDM) or UV-cured resin-based 3D printings are widely used techniques for rapid prototyping today. The prototypes are typically made of various thermoplastics such as acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), and polyethylene terephthalate glycol (PETG) with each thermoplastic having different properties. However, FDM or resin-based 3D printing cannot manufacture metal parts due to some inherent engineering challenges, such as the requirement of the extremely high melting temperature of the metals, making metal filaments, and involved complex thermal management. This thesis research has explored and studied the possibility of manufacturing metal parts using an ordinary FDM 3D printer, a specialized kiln, and PLA-Cu filament with 80% - 90% of copper (Cu) contents. The parts were debound and sintered in the kiln to burn off the PLA, which allowed the Cu to bond to create pure Cu parts. The 3D printing flow rates, debinding and sintering times in the kiln were varied to understand the effect of these parameters on the material characteristics and mechanical strength of the printed Cu samples. The ASTM D638 samples were 3D printed at three flow rates: 133%, 135%, and 140% in an FDM printer and debound and sintered at three different times: 3 hour debind 3 hour sinter, 3 hour debind 4 hour sinter, and 3 hour debind 5 hour sinter. The dimensions and weight of the samples were measured before and after sintering. Samples were polished and etched using a 5-step polishing method with different grinding grits (coarse to ultrafine) and etched with ferric chloride. Grain boundaries and surface qualities of the 3D printed and sintered samples were observed under a high-precision material microscope, stored, and compared with the cold-rolled annealed copper samples. The tensile strength of the samples was evaluated using Universal Testing Machine (UTM). The results show that the 135% 3-hour debind and 4- hour sinter provided the best overall results for the least amount of void within the sample, nicer grain boundaries and mechanical strength. The average stress vs strain value for cold rolled annealed copper is 220.6 Mpa. The results from the tensile testing came out to have a maximum of 39.107 MPa in the 133% flow rate 3 hour debind 4 hour sinter. The second highest stress value came from the 135% flow rate 3 hour debind 4 hour sintering time group at 37.29 Mpa. While the quality and material grain boundaries are comparable with cold-rolled annealed samples, the mechanical characteristics are far off. Nonetheless, the overall aspect of making copper parts from conventional FDM-based 3D printing technology is promising. The findings of this research will contribute to understanding and better utilization of FDM-based 3D printed Cu and general metal parts for future engineering endeavors.

Rapid digital transformation is forcing the manufacturing industry to drastically alter its current trajectory for future success. The remarkable convergence of digitalization and manufacturing is reshaping industries, ushering in an era known as Industry 5.0. This revolutionary transition has given birth to digital manufacturing and smart factories, heralding a new dawn in the way we produce goods. The amalgamation of artificial intelligence (AI), robotics, the internet of things (IoT), augmented reality (AR), virtual reality (VR), big data analytics, cloud computing, and additive manufacturing stands poised to unlock unprecedented avenues in the realm of production. Practitioners, researchers, dreamers, and pioneers all are beckoned to explore the uncharted territories of digital innovation in manufacturing. Human-Centered Approaches in Industry 5.0: Human-Machine Interaction, Virtual Reality Training, and Customer Sentiment Analysis spans domains from mechanical and electrical engineering to computer science, from industrial economics to business strategy, and this book addresses this diverse audience. The book embarks on a comprehensive voyage, unveiling the latest evolutions and nascent trends within digital manufacturing and smart factories. From inception to execution, from design optimization to predictive maintenance, every phase of the manufacturing lifecycle is scrutinized through the lens of cutting-edge technologies. Rather than relying exclusively on the theoretical realm, this book also ventures into the crucible of real-world application, offering practical insights drawn from varied industries, including automotive, aerospace, and pharmaceuticals.

Additive manufacturing (AM) is now being used to produce series components for the most demanding applications. It is a disruptive, if not revolutionary, manufacturing technology. The biggest advantage of this technology is its capacity to make parts with any free form, thus paving the way for free and complex part design. Components and integrated structures with complex designs that would not have been possible just a few years ago can now be made according to various requirements. The net-shape manufacturing capacity of AM allows a considerable saving of materials, conventional thermomechanical processing, and machining processes, making it an environmentally friendly manufacturing technology. This book includes two sections that cover new approaches in AM for biomedical applications and advanced technological solutions.

The 3D printing (3DP) process was patented in 1986; however, only in the last decade has it begun to be used for medical applications, as well as in the fields of prosthetics, bio-fabrication, and pharmaceutical printing. 3DP or additive manufacturing (AM) is a family of technologies that implement layer-by-layer processes in order to fabricate physical models based on a computer aided design (CAD) model. 3D printing permits the fabrication of high degrees of complexity with great reproducibility in a fast and cost-effective fashion. 3DP technology offers a new paradigm for the direct manufacture of individual dosage forms and has the potential to allow for variations in size and geometry as well as control dose and release behavior. Furthermore, the low cost and ease of use of 3DP systems means that the possibility of manufacturing medicines and medical devices at the point of dispensing or at the point of use could become a reality. 3DP thus offers the perfect innovative manufacturing route to address the critical capability gap that hinders the widespread exploitation of personalized medicines for molecules that are currently not easy to deliver. This Special Issue will address new developments in the area of 3D printing and bioprinting for drug delivery applications, covering the recent advantages and future directions of additive manufacturing for pharmaceutical products.
