In contrast, 3D printing allows for the creation of highly intricate geometries that would otherwise be impossible or prohibitively expensive to produce using conventional methods.

Tooling and Prototyping: 3D printing also offers substantial savings in the prototyping and tooling stages. In the past, creating a new prototype often involved expensive molds, dies, and other tooling equipment. With 3D printing, companies can quickly produce prototypes at a fraction of the cost and time, enabling faster iteration cycles and more innovation.

Supply Chain Optimization: The on-demand manufacturing capabilities of 3D printing can help reduce inventory and streamline supply chains. Companies can produce parts as needed, rather than maintaining large inventories of spare parts, which is especially beneficial for the aerospace sector, where many parts are produced in small quantities. This capability is particularly useful for producing rare or obsolete parts, where traditional supply chains might not be viable.

Reduction in Material Waste: Traditional manufacturing techniques often result in significant material waste, especially when parts are machined from solid blocks of metal. With 3D printing, material is added layer by layer, which reduces waste and ensures that only the material needed for the part is used.
