Laser consolidation (LC) is a novel additive manufacturing process being developed by the National Research Council Canada (NRC) at its London facility. LC offers unique capabilities in the production of net-shape functional metallic parts requiring no further post-machining. NRC’s LC technology has achieved dimensional accuracy of up to +/−0.05 mm with a surface finish up to 1 μm Ra (depending on the materials used in the manufacturing process). The LC process differs from other additive manufacturing technologies by its high precision deposition system that can build functional parts or features on top of existing parts using various high performance materials and alloys. In this paper, laser consolidation of various high performance materials (such as Ni-base super alloys and Ti-6Al-4V alloy) will be discussed and the examples will be given on building complex functional components and repairing parts otherwise unrepairable for gas turbine and other applications.

AbstractMankind is setting to colonize space, for which the manufacturing of habitats, tools, spare parts and other infrastructure is required. Commercial manufacturing processes are already well engineered under standard conditions on Earth, which means under Earth’s gravity and atmosphere. Based on the literature review, additive manufacturing under lunar and other space gravitational conditions have only been researched to a very limited extent. Especially, additive manufacturing offers many advantages, as it can produce complex structures while saving resources. The materials used do not have to be taken along on the mission, they can even be mined and processed on-site. The Einstein-Elevator offers a unique test environment for experiments under different gravitational conditions. Laser experiments on selectively melting regolith simulant are successfully conducted under lunar gravity and microgravity. The created samples are characterized in terms of their geometry, mass and porosity. These experiments are the first additive manufacturing tests under lunar gravity worldwide.

Manufacturing Technologies

The use of conventional manufacturing methods is mainly limited by the size of the production run and the geometrical complexity of the component, and as a result we are occasionally forced to use processes and tools that increase the final cost of the element being produced. Additive manufacturing techniques provide major competitive advantages due to the fact that they adapt to the geometrical complexity and customised design of the part to be manufactured. The following may also be achieved according to field of application: lighter weight products, multimaterial products, ergonomic products, efficient short production runs, fewer assembly errors and, therefore, lower associated costs, lower tool investment costs, a combination of different manufacturing processes, an optimised use of materials, and a more sustainable manufacturing process. Additive manufacturing is seen as being one of the major revolutionary industrial processes of the next few years. Additive manufacturing has several alternatives ranging from simple RepRap machines to complex fused metal deposition systems. This paper will expand upon the structural design of the machines, their history, classification, the alternatives existing today, materials used and their characteristics, the technology limitations, and also the prospects that are opening up for different technologies both in the professional field of innovation and the academic field of research. It is important to say that the choice of technology is directly dependent on the particular application being planned: first the application and then the technology.

Student Inquiry

Is the primary purpose of a 3D printer to manufacture a product? Yes, but students and teachers can also use 3D printers to learn about and engage in research and experimentation. This could begin with product research and development, then expand to technical areas based on additive manufacturing technologies, the physical and mechanical properties of additive manufacturing materials, and the properties of 3D printed products. Student inquiry can take the form of formal or informal experimentation and observational studies. Although dedicated testing equipment can facilitate more demanding investigations, it is possible for quite a bit of experimentation to be done with little or no dedicated testing equipment. It is hoped that the reader will identify different educational experiences with experimentation that might fit their learners' needs and see 3D printers as tools for conducting and teaching about research, including product research and development and research into process engineering and materials.

AbstractThis paper aimed to provide a foundation database for understanding the important applications of the different additive manufacturing (AM) technologies for musical wind instruments. A systematic review methodology was adopted in this study. The different AM techniques, materials used, the technical features, and processing parameters uniquely related to wind instruments were discussed. Selected heterogeneous applications demonstrate how AM techniques are being exploited in the innovation, improvement in aesthetics of the existing wind instruments, understanding the ancient music, and personalization with its capability to tune specific instrument design parameters for professional musicians.
