::: Laser Metal 3D Printing Technology

The process begins with the creation of a three-dimensional (3D) model using computer-aided design (CAD) software. This 3D model is saved as an STL format file, which is the triangulated representation of the model. The software then splits the file data into individual layers and is sent to the SLM machine.

In the configuration of the laser beam powder fusion machine, a heat source (laser) selectively melts a bed of powder previously deposited in very thin and uniform layers (the layers indicated in 3D) on a platform, generating the contour and interior of the part. This construction platform descends in the z axis after each layer a distance equal to the thickness of the layer (generally between 20 and 50 microns), an action that is repeated until the piece is completed.


The system controls the modulation and firing of a medium power laser, guided by fiber optics to a galvo head that directs the beam over the powder bed.


A brush is responsible for evenly spreading a layer of metallic powder a few microns thick


A pair of mirrors direct the laser beam onto the powder bed, specifically melting certain areas of the work area.


After finishing a layer, it moves in the vertical axis allowing work on a new layer of metal powder.
