On metals under 1 inch, fiber laser dominates. A 12kW Vantix system cuts 10mm mild steel at roughly 4,500 mm/min. A typical abrasive waterjet manages 600-800 mm/min on the same thickness. At 3mm stainless, fiber laser runs 10,000+ mm/min versus waterjet at 1,200 mm/min. With rapid traverse speeds of 140 m/min and 1.5G acceleration, Vantix systems spend less time repositioning between cuts.
For metal-focused shops, the throughput difference is transformational.
Waterjet's biggest hidden cost is garnet. A busy waterjet consumes 0.5-1.5 lbs per minute. At $0.25-$0.40/lb, that adds up to $15,000-$40,000 per year in abrasive alone. Add water treatment, pump rebuilds every 1,000-2,000 hours, and orifice replacements. Fiber laser's primary consumables are assist gas and periodic nozzle replacement. Energy consumption is lower per cut-inch.
Waterjet has a material range that laser cannot match. Stone, glass, ceramics, carbon fiber, rubber, foam. For shops processing mixed materials including non-metals, waterjet remains essential. Waterjet also wins when zero HAZ is a hard requirement. For very thick metal above 3-4 inches, waterjet maintains quality while laser edge quality degrades.
