Laser metal deposition (LMD) is also known as generative laser welding. In contrast to laser metal fusion (LMF), where the process takes place inside a 3D printer, LMD takes place in the open air. TRUMPF has thus mastered both important methods for metal 3D printing: laser metal deposition (LMD) and laser metal fusion (LMF).
- The laser generates a weld pool on the surface of the existing component. A nozzle is used to add powder at the same time, which is melted on to produce the desired shape.
- The nozzle sprays the fine metal powder onto the base body. The laser beam comes from the center of the nozzle.
- The material that is applied can extend and grow in any direction.
- LMD saves time: Compared against other additive methods it enables higher build rates, which speeds up the process.
- LMD enables you to switch between different materials in additive manufacturing. Several different powder containers can be active, which means alloys can also be formed. The spectrum ranges from nickel, cobalt, and aluminum through to copper and titanium. By combining different materials, it is also possible to create structures similar to a sandwich design.
- Great creative freedom: Since there is no need for a build chamber, it is also possible to build large components. The laser also has unrestricted access to the base body.
- LMD can be found in many industries, for example the aviation and aerospace, energy, petrochemical, automotive, and medical technology sectors.
