Additive Manufacturing

Powder bed and powder nozzle: How imagination and metal powder create groundbreaking solutions

Structures that seemed previously impossible. Efficient temperature control of entire geometries in confined space. Just two examples of how additive manufacturing opens completely new dimensions of thinking and working.


In laser powder bed fusion (L-PBF), lasers are used to melt down high-performance metal powders layer by layer, before shaping them into the desired form. In laser metal deposition (LMD), on the other hand, a powder nozzle and lasers are used to deposit the material precisely on to the tool. We perform this process using a bespoke Trumpf TruLaser Cell 3000 with a horizontal and vertical rotary axis. We then use machining processes to refine the unmachined parts, turning them into complete functional components.


Additive Manufacturing enables the production of highly complex geometries without the need for any tools – much more quickly and with fewer resources than traditional production methods. And the high-quality results speak for themselves. We can even fulfil the stringent requirements of aerospace, motor sports or medical technology. We have been Nadcap and TÜV Süd certified since 2018. Using the powder nozzle, we can repair defective components, apply coatings and wear protection, and produce hybrid structures. Our nozzle technology and our machinery’s design also allow us to perform extreme high-speed laser material deposition (EHLA), which is a process developed by the Fraunhofer Institute for Laser Technology ILT.

Quality assurance.

In addition to analysing the powder used, toolcraft evaluates the properties of additively manufactured test pieces, as these are representative of the subsequently produced components. The dynamic strength of various metals is evaluated by fatigue testing. The resulting Wöhler curves indicate the relationship between the number of cycles to failure and the applied stress.


Process Chain – Additive Manufacturing (L-PBF and LMD)

Additive Manufacturing (AM) relies much more heavily on practical experience in the various stages of the process than any other production method. toolcraft covers the complete process chain under one roof: from design to manufacturing and finishing. This is rounded off on the digital side with an end-to-end software solution – Siemens' NX. toolcraft’s in-house quality assurance lab sets new standards.

Design und simulation

From traditional design to reverse engineering and topology optimisation, there are many sides to additive design. In addition to being printable, designs must be validated for their intended purpose. We do this by using powerful FEM and CFD software, which is fully integrated into our Siemens system. Combined with our use of warpage simulation software and component compensation methods, our employees’ long-standing expertise allows us to successfully follow the first-time-right approach.

Materials analysis

Our in-house measuring and testing laboratory provides us with the answers we need to ensure reliable component quality. Our analyses cover a wide range of aspects, ranging from the inspection of materials on receipt and process-related analyses (e.g. thickness measurements, structural analysis and analysis of mechanical properties) to the preparation of comprehensive reports.

Additive Manufacturing – L-PBF and LMD

We have a variety of powder bed equipment, including a machine for processing copper using a green laser.
An LMD (powder nozzle) system complements this innovative machinery and enables additional areas of application such as coatings and layers to the existing material as well as to perform repairs and create joints.

Heat treatment

In order to reduce tension in the components (stress relief annealing/ solution annealing) and obtain the required material properties (mechanical properties, hardness and microstructure), we carry out heat treatment – in a chamber, convenction or vacuum furnace, depending on the project`s specific requirements.

Further processing / finishing

Automated and complete depowdering, separation of components and removal of support structures, creation of surface finishes for visually and technically flawless surfaces in accordance with customer specifications, quality assurance to support processes, machining further processing.

Quality assurance

Depending on our customer’s requirements, we may perform tactile and optical measuring in our in-house quality assurance department. In our lab, we not only analyse the powder used, but also inspect the properties of additively manufactured test pieces, as these are representative of the subsequently produced components. Here we work with static and dynamic test benches, among other things.
