From a 3D model, additive manufacturing components are manufactured from powder and laser light. Each layer of the component is produced layer by layer.
Without the need for tooling, additive manufacturing enables the creation of geometrically complex (any shape can be created) objects which are unable to be produced using traditional machining methods.
Within this process the laser light is the key component as it melts the powder and then solidifies.
The technology range from TRUMPF involves Laser Metal Fusion (LMF) and Laser Metal Deposition (LMD).
Laser Metal Fusion (LMF)
Using this method, new components are created by building up layers of powder to produce a whole part. This method is ideal for prototypes or highly complex small pieces in low quantities.
Laser Metal Deposition (LMD)
This method involves the laser generating a weld pool on the surface of the component. A metal filler material powder is then continuously added and melted on this pool. This creates beads that are welded to one another, which then form structures on existing base bodies or entire components. This method is ideal for coating and repair work.
