3D cutting head in a laser cutter – 2D, 3D, and bevel cuts in a single machine

In the production of steel structures, frames, beams, and welded components, the condition of the workpiece as it exits the machine is becoming increasingly important—not just whether it has been cut, but whether it is ready for the next process. A laser with a 3D cutting head allows you to combine 2D cutting and angle cutting in a single cycle, reducing the number of post-cutting operations.

Not Just Cutting — Preparing the Part for Production

In the traditional process, the machine cuts out the shape, and the workpiece is then sent on to the next steps: drilling, chamfering, grinding, manual edge finishing, and preparation for welding. Each of these steps involves time, an operator, transport between workstations, and the risk of error.

A laser with a 3D cutting head changes this process. In a single cycle, the machine can produce the outer contour, mounting holes, process cuts, bevels, and weld bevels. The more of these operations the CNC machine takes over, the less work remains for the operator, welder, or metalworker.

2D Cutting and 3D Cutting — How They Differ and What They Offer Together

2D cutting is the foundation of the process. It allows for the quick and repeatable cutting of contours, machining and mounting holes, cutouts for screws, pins, and fasteners, shapes for folding and welding, and repeatable mass-produced parts. A well-designed part produced by 2D cutting can be immediately ready for quick assembly—provided that the components have the appropriate holes, undercuts, and reference points.

The 3D head expands capabilities to include angled cutting. The machine can perform process bevels, edge chamfering, edge preparation for welding, more complex component finishes, and cutting of profiles requiring precision-fit joints. The 3D head offers the greatest value when the workpiece is to proceed directly to the next stage of production immediately after leaving the machine.

2D Cutting vs. 3D Print Head — What Each One Does

The beam and profile are ready for welding as soon as they come off the machine

A good example is a steel beam or structural member that must later be welded, bolted, or joined to other parts. In the traditional process, such a beam requires several operations: cutting to length, drilling holes, preparing the ends, beveling the edges, and cleaning the weld areas.

With the right machine and the appropriate technology, some of these operations can be performed directly during the cutting process. The beam exits the machine with pre-drilled holes, trimmed ends, mounting cutouts, and bevels for welding—without the need for manual adjustments or additional workstations.

This also affects quality. The welder doesn’t have to spend time manually aligning the parts. The fitter doesn’t have to correct the geometry. The more work the CNC machine does, the more predictable the entire process is and the fewer differences there are between parts.

Bevels for welding without a separate workstation

In many facilities, preparing edges for welding is one of the steps that significantly affects production time. If each edge must be machined, ground, or chamfered manually at a separate workstation, the process becomes more dependent on people, tools, and work organization.

The 3D cutting head helps mitigate this problem. Beveling can occur during the cutting process itself—the workpiece is not removed from the machine, set aside, transported, repositioned, and machined again.

In mass production and for repeatable welded components, every repeatable machine-cut bevel means less manual labor and a lower risk of variations between parts. For the welding shop, this means more predictable edge preparation. For the entire plant, it means a shorter production path for the part.

Laser Cutting of Tubes, Profiles, and Structural Sections

The 3D cutting head and advanced laser cutting are important not only for sheet metal. In structural fabrication, pipes, profiles, and sections are frequently processed—components that require precise alignment of ends, holes, notches, and the geometry of joints.

When cutting pipes and profiles, the following are particularly important: cutting the component precisely to length, preparing the ends for joining, drilling mounting holes, cutting openings for component passage, making process cuts, and ensuring repeatability of parts in a series.

A well-prepared profile can go directly from the machine to the assembly line. This is particularly important in the production of frames, trusses, load-bearing structures, platforms, railings, and components that require repeatable connections.

When does a 3D print head make the most sense?

A 3D scanner is particularly valuable when a company performs the following:

• welded components, beams, and structural parts,
• machine frames and large-scale components,
• profiles and sections that require a precise fit,
• a series of parts with repetitive bevels or chamfers,
• parts that currently require a lot of manual labor after cutting.

This solution is not necessary for every manufacturing operation. If a facility primarily produces simple sheet metal parts without welding or chamfering, a standard sheet metal laser cutter may be sufficient.

An investment in 3D cutting should not be evaluated solely in terms of cutting time. You also need to factor in the time saved on chamfering, grinding, moving parts, rework, and preparing components for welding. In mass production, every minute spent on rework is multiplied by the number of parts.

The Role of STIGAL — Selecting the Right Machine for the Actual Process

STIGAL is a Polish manufacturer of CNC metal-cutting machines. We design solutions for facilities that need not only to cut material but also to achieve real improvements in production: from sheet metal cutting, through tube and profile machining, to preparing components for welding.

The selection of a machine with a 3D cutting head should be based on actual workpieces—not simply on the desire to have more advanced technology. First, we determine what parts are being produced, what operations are performed after cutting, and which of these can be transferred to the machine. The following factors are important: the type and thickness of the material, the dimensions of the sheets, beams, tubes, or profiles, the types of bevels, welding requirements, and the expected result once the part leaves the machine.

Only after conducting such an analysis do we select the appropriate configuration for the laser cutter: work area, cutting head, power source, control system, and accessories for tubes and profiles. An example of a machine with a full range of 2D and 3D cutting capabilities is the FIBER Master HD —a platform designed for the production of components requiring advanced edge preparation.

Summary

A 3D cutting head in a laser cutter provides the greatest value when the machine is used to prepare a workpiece for further production, rather than simply cutting out its shape. The combination of 2D and 3D cutting allows for the creation of contours, holes, undercuts, bevels, and chamfers in a single process.

As a result, a beam, profile, section, or structural component can be ready for welding, assembly, or further processing as soon as it leaves the machine, without the need for many additional operations. In a well-planned process, manual chamfering, grinding, geometry correction, and transport between workstations are minimized.

This solution is designed for companies that want to shorten the production cycle, improve consistency, and gain greater control over the quality of welded and structural components.
