1.1 Definition and Core System

(3d printing alloy powder)

Metal 3D printing, additionally referred to as metal additive production (AM), is a layer-by-layer construction technique that constructs three-dimensional metallic components directly from digital models utilizing powdered or cable feedstock.

Unlike subtractive methods such as milling or transforming, which remove product to achieve form, steel AM adds material only where needed, allowing unprecedented geometric intricacy with very little waste.

The process starts with a 3D CAD design cut right into slim straight layers (usually 20– 100 µm thick). A high-energy source– laser or electron light beam– selectively melts or integrates metal fragments according per layer’s cross-section, which solidifies upon cooling down to develop a dense strong.

This cycle repeats till the full part is built, often within an inert atmosphere (argon or nitrogen) to avoid oxidation of reactive alloys like titanium or light weight aluminum.
