Additive Layer Manufacturing: how it works
Additive manufacturing is usually referred to as 3D printing, because it performs in a similar way to a laser printer. The method builds a sound object from a series of layers - each printed straight on leading from the previous one.
The raw content for ALM can be a powder, which may be a thermopolymer or perhaps a metal; aluminium, stainless-steel and titanium 6,4 are common. The printing chamber is generally heated to 10ºC under the melting stage of the materials - this assures the laser utilized to heat the powder can melt it rapidly. For metals,

The machines’ running computer software cuts the CAD model of your workpiece into slices, whose thickness depends on the kind of substance utilised; Calm uses 0.1mm for polymers and thirty microns for metals. A blade mounted on a moving arm sweeps an even layer of the powder on prime of the work floor inside of the chamber, then a laser - typically around 200W - scans forwards and backwards above the floor,

Other ALM devices use electron beams instead of lasers, as they are able to transmitting much more power and so melt the powder faster. These machines work at area temperature,
