In additive manufacturing, a thin layer of powdery material is distributed on a construction platform inside an industrial 3D printer. Usually, a laser beam fuses together the outline, layer by layer, on the basis of pre-configured construction data.This makes it possible to manufacture any form that can be built using a 3D CAD program. Expectations are increasing in terms of quality and efficiency.
The preheating of the powder bed is a key step – and is performed using infrared emitters.
Alongside the type of powder material used, heat distribution within the chamber is another crucial factor. Heraeus offers infrared lamps that can be precisely tailored to the material – in terms of power, form, and wavelength.
