Market World 3D Printing & Additive Manufacturing | Page 2

Additive manufacturing refers to a process by which digital 3D design data is used to build up a
component in layers by depositing material. The term "3D printing" is increasingly used as an
alternative for Additive Manufacturing.
Additive manufacturing builds up components layer by layer using materials which are available in
fine powder form. A variety of different metals, plastics and composite materials can be used.Additive
manufacturing machines complete a build in one step with no interaction necessary during the build
phase. For additive manufacturing as soon as the CAD design is finalized it can be uploaded to the
printer and printed in one step in a couple of hours.
3D printing allows to produce very complex products. The higher the part complexity, the better
advantage 3D printing has over conventional methods such as subtractive manufacturing.
Furthermore, 3D printing efficiently uses nearly 100% of the raw material, giving rise to negligible, if
not zero waste.

The factors that propel the growth of 3D Printing & Additive Manufacturing in the Aerospace &
Defence Market include increasing demand, wide range of applications and technological
innovations.
In addition, 3D printing technologies assist the design of parts with complicated geometries or difficult
aerodynamic properties if not impossible to manufacture with traditional procedures for engine
parts, turbine, aircraft wing or cabin interior. Moreover, there is very less material wasted and great
speed at which parts can be produced compared to traditional manufacturing methods.
On the other hand, there are also factors that may hamper the growth of the market such as high cost
of production, requires post-processing and discontinuous production process. In addition, extensive
knowledge of material design and the additive manufacturing machine itself is necessary to make
quality parts.
3D Printing & Additive Manufacturing in the Aerospace & Defence Market is classified on the basis of
type, technology, application and geography. Based on type the market is bifurcated into plastics
material, ceramics material, metals material and other material. Based on application, the 3D Printing
& Additive Manufacturing is bifurcated into commercial aerospace, defence, space and others.
