Understanding the key differences

The following sections explain why the differences between waterjet and laser cutting can be decisive in practice – from material processing and material versatility to precision, cut quality and the typical applications of each process.

Cold vs. thermal cutting

The key difference lies in the way the material is cut. While laser cutting uses heat to separate the material, waterjet cutting is a cold cutting process with no thermal impact. As a result, there are no heat-affected zones or thermally induced distortion. Material properties remain unchanged and components can be machined particularly gently, making the process especially suitable for heat-sensitive materials.

Material versatility and material thickness

Few cutting processes offer the same level of versatility as waterjet cutting. While laser cutting is primarily used for thin to medium material thicknesses and may be limited with certain materials (such as transparent, highly reflective or multilayer materials), waterjet cutting can process virtually any material – from metals and plastics to composites, glass, ceramics and stone. The range extends from thin foils and intricate precision parts to materials several hundred millimetres thick.

Precision and fine detail

Both waterjet and laser cutting enable highly precise cutting and the production of intricate geometries. Which process delivers the best results depends on factors such as the material, part geometry and quality requirements. Modern waterjet systems achieve dimensional tolerances of up to ±0.02 mm, positioning accuracy of up to ±0.005 mm and minimum radii from 0.1 mm. This allows even demanding materials to be processed with exceptional accuracy and fine detail.

Cut quality and post-processing

The quality of the cut edge can be crucial, particularly for sensitive materials, demanding surface finish requirements or subsequent machining operations. While laser cutting may cause heat-related changes or discoloration depending on the material and application, waterjet cutting is performed without thermal impact. This eliminates heat-affected zones and edge hardening. Material properties remain fully intact, cut edges are virtually burr-free, and surface finishes up to N7 can be achieved.

Cost-effectiveness and typical applications

There is no universal answer as to which process is more economical. Costs depend on factors such as the material, part geometry, quality requirements and production volume. In principle, both waterjet and laser cutting are suitable for everything from single parts to high-volume production. While laser cutting is often preferred for standardized components and series production, waterjet cutting is particularly well suited to prototypes, one-off parts, small production runs and projects requiring short lead times or a high degree of flexibility.

When waterjet cutting is the better choice

Waterjet cutting offers particular advantages wherever material properties must be preserved, demanding materials or large material thicknesses need to be processed, or where precision and flexibility are key requirements.

Material properties remain unchanged

No heat-affected zones, no thermally induced distortion and no changes to the material properties.

Suitable for virtually any material

Precisely cuts virtually any material, from metals and plastics to glass, ceramics, stone and composite materials.

From precision parts to large components

From thin foils and intricate precision parts to materials several hundred millimetres thick.

Maximum precision and complex geometries

Dimensional tolerances up to ±0.02 mm, minimum radii from 0.1 mm and demanding 2D, 2.5D and 3D geometries.

Excellent cut quality and minimal post-processing

Low-burr cut edges, surface finishes up to N7 and a narrow kerf reduce material consumption and minimise post-processing.

From prototypes to small production runs

High flexibility, short setup times and minimal preparation enable fast and cost-effective production.
