Laser Melting is an additive manufacturing process, which allows for the building of complex metal components directly from 3D CAD data.
First, the 3D file is elaborated, adding, if necessary, supports or bases. The three dimensional model is then sliced into very thin sections with a thickness ranging from 20 to 80 microns thanks to precision software. The file is then sent to the Laser Melting machine, which recognizes each section and recreates the original 3D shape, by melting, layer after layer, the schematized areas. This process can be used to produce components made from multiple metal alloys.
The advantages of additive manufacturing technologies are many: the design phase is free from geometrical limitations (e.g. very complex shapes with internal cavities); the components can be customized and their weight reduced through geometry optimization; assembling phases can be reduced; waste material can be minimized and machining can be limited only to the areas that need tight tolerances and high surface finishing.
CI-ESSE is one of the first Italian companies to have adopted additive technologies. Today, its additive manufacturing department counts 4 M2 cusing machine (Concept Laser) and 1 M1 cusing machine (Concept Laser). In addition, CI-ESSE was the first Italian company to install an X line 2000R®, the world’s largest metal melting machine (160 l build volume).
