LaserCusing®: What exactly is it?
Let's start off by defining the term. LaserCusing® is made up of the letter C from our partner Concept Laser and the word fusing for "complete melting". And this is exactly what we do at the Laser Add Center. The process at a glance: A digital, three-dimensional data set provides the required geometry. From this, extremely fine-grained, single-component metallic powder materials, such as cobalt-chromium or titanium, are applied to a base plate in 25 to 50-micrometer (µm) layers. The new component is now melted and fused, layer by layer, down to the last micrometer using a high-performance precision laser in a special inert gas atmosphere. The finished product emerges after patented and repeatedly proven post-processing — or in their hundreds thanks to series production. And as virtually the entire value chain is digitized, we'll deliver your order back to you in part after just a day.
Focus: metallurgy of the laser-melting process
From a metallurgical viewpoint, laser-melting with a high-performance laser melts the metal or alloy's lattice structure, which reforms as it cools down. Benefiting you and your requirements:
- Enhanced material properties of the end products than with laser sintering, in which powder is sometimes only partially melted
- Increased rigidity and toughness and fatigue limit of the finished components than with casting
- Cavity-free product and virtually absolute density as well as warpage-free workpieces
