 3D printing, also referred to as additive manufacturing, is a process of creating a layer-by-layer three-dimensional object using computer-aided design (CAD) models. Unlike conventional manufacturing techniques, the 3D printing process generates less waste and higher accuracy components. The 3D printing technology was primarily used for rapid prototyping and concept generation, however, with advancements in material technology, the process has proliferated its scope of operations to manufacturing complex components. The design freedom gained by engineers to print a complex component in one piece with the possibility to replace several small joints and machined parts has generated unprecedented business opportunities within the aerospace vertical. The ability to print parts in small volumes as and when needed without incurring any additional capital expense due to lower volume notably impacts the supply chain dynamics of the market.

The growth of the global aerospace 3D printing market is driven by factors such as increase in demand for lightweight & durable components from the aerospace industry, simplification of complex designs, ease of prototyping, and rapid customization among others. However, high initial investment and unstable regulatory framework are key factors limiting the business opportunities; however, these challenges are expected to dilute by 2025. This is attributed to the fact that industry stakeholders are engaged in developing new operational strategies to counter costing challenges. Cloud production and shared production space are expected to emerge as an additive manufacturing trend during the forecast period. Design methodologies of engineers are expected to shift from Design for Additive Manufacturing (DFAM) to embracing design freedom and producing highly complex single-piece components, thus supporting the business trend.

Increase in demand for lightweight & durable aerospace components

Rise in jet fuel charges and implementation of stringent government regulations on carbon footprint generated by the aviation industry have allowed aircraft manufacturers to explore ways of increasing fuel efficiency. According to IATA, the airline industry is expected to achieve net-zero carbon emissions by 2050. Reducing the net weight of an aircraft and engine optimization and the primary approach practiced by aircraft manufacturers to improve fuel efficiency and achieve the designated goal. Additive manufacturers allow aircraft manufacturers to leverage the benefits of design optimization and notable weight reduction. Complex assemblies can be collated into single components using 3D printing technologies, reducing the complexity of the operation and net weight. 

Cloud-based 3D printing services

Integration of additive manufacturing technology with cloud management services will serve as a major factor in defining the market potential within the aerospace industry over the coming years. Remote manufacturing & management, optimization of the component on the go, and real-time monitoring are some basic features supported by cloud-based 3D printing services. Companies offering such services have established their machines in their plants as well as in their dealer network facility.

Companies have adopted product development, collaboration, and long-term agreements as their key development strategies. The key players operating in this market are Markforged, Liebherr, Stratasys Ltd., Materialise NV, EOS GmbH, 3D Systems Corporation, Honeywell. General Electric, Exone, Norsk Titanium, Renishaw PLC, TrumpF, SLM Solutions, Envisiontec, Inc., Prodways, and Hoganas AB.
