The global military 3d printing market was valued at $0.88 billion in 2021, and is projected to reach $7.5 billion by 2031, growing at a CAGR of 24.8% from 2022 to 2031.

3D printing, referred as additive manufacturing, comprises printing a part layer by layer from a 3D CAD model. 3D printing aids in reduction of lead time as well as cost for prototyping and manufacturing complex parts. No special tools such as cutting tool or molds are required for printing process. The materials utilized for 3D printing comprises of several types of polymers, metals, ceramics, and others. The selection of printing material depends on traits expected from printed object. Certain 3D printers utilizes several materials simultaneously according to requirements, thereby making manufacturing process easier. At present, the defence industry has adopted the 3D printing technology to simplify the process of manufacturing of parts and components, as well as weapons and equipment. With the changes in battlefield requirements, the equipment that changes (shape or properties) in accordance with the environment is likely to help armies gain an upper hand[by Allied Market Research].
