3D laser cutting
3D laser cutting is an effective and highly efficient process for cutting through various materials and substances. BLS Lasertechnology GmbH offers its customers in-depth expertise in this cutting technology – especially with regard to complex laser cuts with critical tolerances and in the 3D range.
What is laser cutting?
Laser cutting – also known as laser beam cutting – is a non-contact process for cutting metallic and non-metallic components. It uses a laser to remove the material by ablation. The laser heats the component surface to such an extent that a plasma is created and the material sublimates or vaporizes. Underlying / adjacent material layers stay undamaged.
A laser can cut almost all materials. The main scope of BLS services includes: aluminum laser cutting, laser steel cutting and sheet metal laser cutting. Our lasers can usually also cut various alloys and special materials, but our experts will validate the ability to process such parts in advance. In principle, even laser cutting of plastic or wood is possible.
We support you
Do you need help with the laser processing of your component? BLS is looking forward to helping you determine the requirements for your 3D laser material processing.
The flexibility and power of a laser allows to cut various material thicknesses extremely precisely, with minimal force and tight tolerances.
While other technologies apply enormous forces to parts, laser cutting generally avoids deformation, distortions or other defects. Due to the high accuracy, 3D laser cutting can even cut complex geometries with difficult-to-access areas.
The automated guidance of the laser enables an economic and highly efficient production of small and large quantities. In addition, there is only minimal waste compared to alternative cutting methods such as punching or nibbling. For large-scale production, BLS can also (partially) automate loading and unloading as required. The technology thus offers the ideal properties for efficient cutting of complex jobs.
Trust in over 30 years of experience.
With extensive laser experience, BLS supports customers as a contract manufacturer from parameter determination / basic development through prototype production to serial production. A high-performance machine park and different laser types enable an overall optimized service offering. The quality management system and exchange with leading research institutions ensure quality at the highest level.

Laser cutting advantages
Laser cutting brings a multitude of advantages for material processing. In addition to the usual metal laser cutting or sheet metal laser cutting, the process can cut a large variety of different materials and component geometries. The automated guidance, high accuracy and high process speed of the laser drive minimal waste and ensure high efficiency as well as low costs.
- Accurate: spot welds up to a minimum diameter of approx. 0.5mm
- Precise: Machine and equipment with a repeatability of up to 0.01mm
- Powerful: material thicknesses from 0.3mm to 10mm, depending on the alloy
- Contactless: No abrasion or wear, penetration of the material by heat exposure
- Efficient: Automated welding on NC-controlled machines in the 2D and 3D range

Laser cutting Procedures
Three processes have become established in laser cutting: Flame cutting, fusion cutting and sublimation cutting. The difference between these cutting processes exists in particular with regard to the use of the cutting gas. BLS supports you in selecting the right process according to your requirements for the cutting process and the required cutting edges on the component.
Flame cutting
Use of oxygen as cutting gas, for cutting with high cutting speeds and thick materials
Fusion cutting
Use of nitrogen or argon as cutting gas, for virtually oxide-free cutting edges and minimal burr formation
Sublimation cutting
Beam evaporates alone, especially for fine, oxide-free cut edges with tight tolerances & complex contours
