Overview
The TRUMPF TruLaser 3040 fiber extends the TruLaser 3000 series to a 4000 x 2000 mm working area, providing capacity for oversize sheet formats that exceed standard 3015 dimensions. This makes it well-suited for structural fabricators, architectural metalwork shops, and heavy equipment manufacturers who routinely work with large-panel components. The TruLaser 3040 fiber uses the same proven TruDisk solid-state laser source as the 3030, available from 3 kW to 10 kW, paired with TRUMPF's flying optics cutting head architecture.
The 4000 x 2000 mm cutting envelope accommodates large sheets that would otherwise need to be repositioned or cut in multiple setups on a standard 3015 machine. This reduces setup time, improves alignment on large parts, and allows uninterrupted cutting of structural components like machine bases, enclosure panels, and agricultural equipment frames. Nesting efficiency also improves significantly on large-area sheets, reducing scrap rates for shops with high material costs.
TRUMPF's TruControl system manages the larger cutting area with the same interface and programming environment as the 3030, so operators familiar with the 3000 series can transition without retraining. TruTops Boost handles nesting and production planning with direct support for the 4000 x 2000 format. The machine supports the full range of cutting gases including nitrogen for stainless fusion cutting and oxygen for mild steel flame cutting, with automated gas control through the cutting head.
The TruLaser 3040 fiber competes with Bystronic's large-format ByStar Fiber and Mazak's Optiplex 4020 in the large-format 2D fiber laser segment. Its larger footprint requires more floor space than a 3015 machine, and pricing reflects the larger cutting area, typically ranging from $550,000 to $900,000 depending on power level and options.

Strengths & Limitations
Strengths
- 4000 x 2000 mm cutting area eliminates repositioning for large panels and structural components, saving setup time and improving part accuracy
- Improved nesting efficiency on large sheets reduces material waste for shops cutting expensive plate stock
- Same TruControl interface as the 3030 allows operators to cross-train easily across machine sizes in a multi-machine shop
- TruDisk fiber source provides low operating cost with no gas or mirror maintenance compared to CO2 platforms
Limitations
- Larger machine footprint requires significantly more floor space than a standard 3015 format machine
- Higher price than 3015 format machines; shops that rarely cut sheets larger than 3000 x 1500 mm cannot justify the premium
- Automation integration (SheetMaster) for 4000 x 2000 mm sheets is more complex and expensive than standard format

Frequently Asked Questions
01
The TruLaser 3040 fiber has a 4000 x 2000 mm working area and can handle sheets up to approximately 1,200 kg. This accommodates standard European 4x2 meter sheet formats and allows cutting of parts that would require repositioning on a 3015 machine.
02
The primary difference is the cutting area: 4000 x 2000 mm versus 3000 x 1500 mm. Both use the same TruDisk fiber source, TruControl system, and TruTops Boost software. The 3040 costs more and takes more floor space but eliminates repositioning for large parts.
03
The TruLaser 3040 fiber is available from 3 kW to 10 kW. The 6 kW and 8 kW configurations are most common for mixed mild steel and stainless steel production. Higher power is necessary for cutting thick plate in the 15-20 mm range at productive speeds.
04
Yes. With nitrogen as assist gas, the TruLaser 3040 fiber produces bright fusion cuts on stainless steel up to 30 mm at 10 kW. For shops requiring CO2-comparable stainless edge quality on thicker material, TRUMPF's optional BrightLine fiber beam shaping is recommended.
05
Pricing typically ranges from $550,000 for base 3 kW configurations to approximately $900,000 for 10 kW machines with full options. The large-format cutting area commands a premium over equivalent 3015 machines.
