LVD Electra BL 3015

Fiber lasers use a solid-state fiber optic gain medium to produce a laser beam with a wavelength of approximately 1,070 nm, while CO2 lasers use a gas discharge tube to produce a 10,600 nm wavelength beam. Key differences: (1) Fiber lasers are 2-3x more energy efficient than CO2 for the same output power; (2) Fiber lasers cut reflective metals (copper, brass, aluminum) much more effectively than CO2 because the shorter wavelength is absorbed better by these metals; (3) Fiber laser beam delivery uses flexible optical fiber cable rather than CO2's rigid mirror/lens delivery system — faster response, less maintenance; (4) Fiber lasers have higher cutting speeds on thin material (<6 mm) but CO2 can produce superior edge quality on thick material (>20 mm).

The LVD Electra BL 3015 cuts: mild steel up to 20 mm (6 kW version), stainless steel up to 12 mm, aluminum alloys up to 10 mm, brass up to 6 mm, copper up to 4 mm, and galvanized steel. The fiber laser's short wavelength provides excellent absorption on copper and brass — materials that CO2 lasers cut poorly due to high reflectivity at 10,600 nm. Each material and thickness combination requires specific gas type (oxygen for mild steel, nitrogen for stainless and aluminum), gas pressure, cutting speed, and focus position — these are managed by the CADMAN-L software's material cutting tables.

Assist gas selection determines cut quality and oxidation on the cut edge: Oxygen (O2) is used for mild steel — it reacts with the steel to accelerate cutting (oxidative burning), producing faster speeds at the cost of an oxidized edge that may need preparation before painting or welding. Nitrogen (N2) is used for stainless steel and aluminum — it provides an inert atmosphere that prevents oxidation, producing a bright, scale-free cut edge ready for immediate use or welding. High-pressure nitrogen is increasingly used for all materials where edge quality is paramount. Gas purity and delivery pressure are critical — the Electra BL uses precision gas regulation with pressures up to 25 bar for high-pressure nitrogen cutting.

CADMAN-L is LVD's dedicated laser cutting CAM software. Unlike general-purpose CAM software, CADMAN-L is purpose-built for 2D flat sheet nesting, cutting path optimization, and LVD laser machine integration. Key features: automatic nesting from imported DXF/DWG parts to maximize sheet utilization; cutting parameter database for all LVD-supported materials and thicknesses; micro-joint and skeleton cutting strategies for part retention; automatic bridge cutting for nested parts; and direct machine program output with cut sequencing optimization. CADMAN-L integrates with CADMAN-B for press brake bending — flat parts programmed in CADMAN-L can be directly imported into CADMAN-B for bend programming.

The Trumpf TruLaser 3030 fiber is the dominant mid-size fiber laser benchmark. Both machines cover the 3x1.5m sheet format and similar power ranges. Trumpf's advantages are the largest installed base, the TruTops software ecosystem, and the most extensive global service network. LVD's advantages are the CADMAN suite for shops also using LVD press brakes, potentially faster delivery in some markets, and in European markets where LVD has comparable service coverage. For North American buyers, Trumpf and Amada generally have stronger local service support. For European buyers or those already in the LVD press brake ecosystem, the Electra BL 3015 is a strong competitor.
