Additive manufacturing (AM) or additive layer manufacturing (ALM) is the industrial production name for 3D printing rapid prototyping, a computer controlled process that creates three dimensional objects by depositing materials, usually in layers. Similar to standard 3D printing, AM allows for the creation of bespoke parts with complex geometries and little wastage. Ideal for rapid prototyping, the digital process means that design alterations can be done quickly and efficiently during the manufacturing process. Unlike with more traditional subtractive manufacturing techniques, the lack of material wastage provides cost reduction for high value parts, while AM has also been shown to reduce lead times.
In addition, parts that previously required assembly from multiple pieces can be fabricated as a single object which can provide improved strength and durability. AM can also be used to fabricate unique objects or replacement pieces where the original parts are no longer produced.
