Additive manufacturing

Components, no matter what shape they have. Prototypes, unique items, and small and large series. Additive manufacturing is shaping the future of the manufacturing industry like hardly any other process. Additive manufacturing and laser sintering can be used to manufacture, coat, or repair components with extremely high material requirements. Compared with traditional, ablative manufacturing methods such as turning or milling, in additive manufacturing the design determines manufacturing. This is why it is referred to as "design-driven manufacturing".

TRUMPF has brought two additive manufacturing laser processes to industrial maturity in the last 20 years which can be used to create complex shapes and individual metal components layer-by-layer from metal powder quickly, with flexibility, and cheaply: Laser metal fusion and laser metal deposition. As a pioneer in additive manufacturing methods, TRUMPF provides complete solutions with machines, beam sources, and services – all of which they have developed and produced themselves. This provides a clear competitive advantage to customers.


In additive manufacturing, there are no limits when it comes to design – even functions that are not feasible with conventional manufacturing methods can be integrated or complete assemblies can be constructed in one go.


The desired components and shapes are created precisely using only the material that is actually required with additive manufacturing.


Customized solutions and personalized components can be realized easily and with flexibility using additive manufacturing – even in series production.

Tool free

Since no tools are required for additive manufacturing, you can work more cheaply and reduce both wear and setup times.


The high level of stability of complex structures and low weight of additively manufactured components make the process particularly attractive for lightweight design.

Which application examples are there for additive manufacturing?

  • Creation of a personalized cranial implant or construction of dental crowns and bridges (LMF)
  • Additive manufacturing of heat exchangers with extremely fine lattice structures (LMF)
  • Coating of a maize chopper in order to improve the service life (LMD)
  • Repair of a compressor blade after wear (LMD)

How are the additive manufacturing processes different?

An increasing number of variants, increasingly small lot sizes – the trend in many manufacturing industries is clear. Laser metal fusion (LMF) and laser metal deposition (LMD) are the two laser-based processes that take on these challenges and make additive manufacturing more and more attractive for industrial use. However, how are the processes different technically and which technology is precisely suited to which fields of application?

Additive manufacturing

In additive manufacturing, components are created from nothing more than powder and laser light. On the basis of a 3D model, the laser constructs the component layer by layer. As such, additive methods contrast with ablation and forming methods, which have predominated in industrial production until now. The paradigm shift toward additive manufacturing carries the promise of producing geometrically complex objects which could not be produced using traditional methods – all without using any tools. One great benefit here is the freedom to design any shapes desired.

The laser is the key element in additive manufacturing. It melts on the metal powder and solidifies it to produce a high-quality workpiece. There are different versions of additive manufacturing for metals: laser metal fusion and laser metal deposition. With laser metal fusion, the laser creates new workpieces by building up layers from powder. This method has proven particularly advantageous when producing prototypes, unique pieces, and small series. With laser metal deposition, the laser generates a weld pool on the component surface. A metal filler powder is then continuously added and melted on in this pool. This creates beads that are welded to one another, which then form structures on existing base bodies or entire components. You can also use this method for coating and repair work.
