Over the past decade, fibre laser cutting systems have moved from being premium-tier equipment reserved for high-volume manufacturers to an accessible tool found in workshops of all sizes. At Committas, fibre laser technology has fundamentally altered the speed, precision and scope of what we can offer our clients.
What Makes Fibre Lasers Different?
Traditional CO2 lasers generate their beam using a gas mixture and a series of mirrors. Fibre lasers, by contrast, generate light within a doped optical fibre and deliver it to the cutting head through a flexible cable. This design eliminates the mirrors, reduces maintenance, improves beam quality and dramatically increases electrical efficiency.
In practical terms, a fibre laser consumes roughly half the electricity of an equivalent CO2 system, requires far less downtime for mirror alignment and delivers a more focused beam that cuts thin materials at higher speeds.
Speed Gains
On materials under 6 mm thick — which account for the majority of sheet metal work — fibre lasers cut two to three times faster than CO2 systems. For a fabrication workshop, this translates directly to shorter lead times. A batch of 200 bracket blanks that might have taken a full shift on a CO2 machine can be completed in a few hours on a fibre laser.
Even on thicker plates (12 mm and above), modern high-power fibre lasers (6 kW and up) match or exceed CO2 cutting speeds while producing a narrower kerf and less heat-affected zone.
Edge Quality
Fibre lasers produce exceptionally clean cut edges on steel and stainless steel. In many cases, laser-cut parts can proceed directly to welding or powder coating without any secondary deburring or grinding. This eliminates a time-consuming manual step and reduces the risk of dimensional distortion from aggressive edge preparation.
On aluminium, edge quality depends on alloy and thickness, but the results are generally superior to plasma cutting and competitive with waterjet for most thicknesses below 10 mm.
Material Versatility
Fibre lasers handle a broad range of metals: mild steel, stainless steel, aluminium, brass, copper and galvanised sheet. This versatility allows a single machine to serve multiple trades — from structural steel fabricators to signage makers to furniture builders — without changing consumables or gas mixes.
Design Freedom
Because the laser follows a CNC-controlled tool path with no physical contact, there are virtually no geometric constraints. Tight internal radii, intricate patterns, narrow slots and densely packed nesting layouts are all achievable. Designers and architects can specify perforated screens, decorative panels and complex brackets without worrying about tooling limitations.
At Committas, we regularly cut parts from DXF and DWG files supplied by architects, engineers and product designers. The transition from digital file to finished part is seamless and repeatable across any batch size.
Environmental and Cost Benefits
Lower energy consumption, reduced waste through optimised nesting software, and longer consumable life all contribute to a smaller environmental footprint. For clients, these savings translate to competitive per-part pricing — particularly on repeat orders where setup costs are amortised across larger quantities.
Is Laser Cutting Right for Your Project?
If your project involves flat parts cut from sheet or plate up to 20 mm thick, laser cutting is almost certainly the most efficient method. For three-dimensional cuts, tube profiles or very thick sections, alternative processes like plasma, waterjet or oxy-cutting may be more suitable. Our team can recommend the best approach based on your material, geometry and quantity.
