The aerospace industry is rapidly adopting 3D printing to build lighter, stronger, and more efficient components, from cabin brackets to rocket engines, while cutting costs and lead times across the entire lifecycle of aircraft and spacecraft. For global OEM brands, wholesalers, and manufacturers, additive manufacturing has moved from experimental pilots to a strategic production tool that works alongside CNC machining, plastics, silicone molding, and metal stamping.
3D printing in aerospace, also called aerospace additive manufacturing, is the process of building components layer by layer from digital models using metal, polymer, or composite materials instead of subtracting material from a block or using traditional tooling. It enables highly complex internal geometries, consolidated multi-part assemblies, and rapid design iterations that were previously impractical or impossible.
Key aerospace 3D printing technologies include:
- Metal powder bed fusion for structural brackets, engine parts, and heat exchangers.
