Abstract Additive Manufacturing (AM) offers design engineers new and advanced manufacturing processes to consider when developing new products or redesigning and evolving current products. AM includes 3D printing processes to quickly produce complex parts and prototypes, that were previously uneconomical or impossible to fabricate. Engineers and organizations have an increasing need to incorporate AM as part of product development; however, design heuristics, design methodologies, and design tools to support AM are nascent and only recently emerging. To enhance Design for Additive Manufacturing (DfAM), this research seeks to develop an accessible, computer-based design assistant that will aid designers in incorporating AM into their design processes. The design assistant implements a distinctive and user-centered Design Innovation (DI) process, set of methods, and set of principles based on a 4D design framework. This 4D framework encompasses the UK Design Council’s double diamond model and includes the phases of Discover, Define, Develop, and Deliver. The Discover phase entails user studies and a deep understanding and empathy for the user. The Define phase considers the reframing of design opportunities based on derived insights from the modeling users’ interactions. The Develop phase uses a variety of methods to create a large quantity of innovative ideas and concepts, and the Deliver phase implements a set of methods to prototype, test, pitch, and ultimately produce deliverables for a market or community. We demonstrate the design assistant tool for AM through the development of high-end bracket design for space applications. The design considers the Selective Laser Melting (SLM) process for productions and incorporated topology optimization approaches. This demonstrative case study shows how the tool includes design heuristics and approaches for each of the 4-Ds that assist designers in implementing AM capabilities as part of repeatable design processes. Assessment of the tool is carried out through systematic assessments performed by practicing design engineers that have knowledge of AM. Initial results show that the design assessment tool is very helpful when designers consider using AM and also in helping them use AM in effective and efficient manners.

Over the last 20 years, there has been growing research and development investment to exploit the benefits of wire deposition additive manufacturing (AM) for the production of near-net shape components in aircraft and space applications. The wire feedstock for these processes is a significant part of the overall process costs, especially for high-value materials such as alloyed titanium. Powders for powder-based AM have tight specifications regarding size and morphology, resulting in a significant amount of waste during the powder production. In the aerospace sector, up to 95% of forged billet can be machined away, and with increasing aircraft orders, stockpiles of such machining swarf are increasing. In this study, the continuous extrusion process—ConformTM—was employed to consolidate waste titanium alloy feedstocks in the forms of gas atomised powder and machining swarf into wire. Samples of wire were further cold-drawn down to 40% reduction, using conventional wiredrawing equipment. As close to 100% of the waste powder can be converted to wire by using the ConformTM process. This technology offers an attractive addition to the circular economy for manufacturers and, with further development, could be an important addition as industries move toward more sustainable supply chains.

The emerging technology of 3D printing can not only be used for rapid prototyping, but will also play an important role in space exploration. Additive manufactured parts can be used in diverse space applications, such as magnetic shields, heat pipes, thrusters, etc. Three-dimensional printed parts offer reduced mass, high possible complexity, and fast printability of custom-made objects. On the other hand, materials which are not excessively damaged by the harsh conditions in space and are also printable by available technologies are not abundantly available. This review gives an overview of recent metal additive manufacturing technologies and their possible applications in space, with a focus on satellites and rockets, highlighting already applied technologies and materials and gives an outlook on possible future applications and challenges.

Recent improvements in additive layer manufacturing (ALM) have provided new designs of geometrically complex structures with lighter materials and low processing costs. The use of additive manufacturing in spacecraft production is opening up many new possibilities in both design and fabrication, allowing for the reduction of the weight of the structure subsystems. In this aim, polymeric ALM structures can become a choice, in terms of lightweight and demisability, as far as good thermomechanical properties. Moreover, provided that fused-deposition modeling (FDM) is used, nanosats and other structures could be easily produced in space. However, the choice of the material is a crucial step of the process, as the final performance of the printed parts is strongly dependent on three pillars: design, material, and printing process. As a high-performance technopolymer, polyether ether ketone (PEEK) has been adopted to fabricate parts via ALM; however, the space compatibility of 3D-printed parts remains not demonstrated. This work aimed to realize a nanosat polymeric structure via FDM, including all the phases of the development process: thermomechanical design, raw material selection, printing process tuning, and manufacturing of a proof of concept of a technological model. The design phase includes the application of topology optimization to maximize mass saving and take full advantage of the ALM capability. 3D-printed parts were characterized via thermomechanical tests, outgassing tests of 3D-printed parts are reported confirming the outstanding performance of polyether ether ketone and its potential as a material for structural space application.
