Laser source power is the first line item. A 1 kW fiber source with a 600 × 400 mm bed can sit near $12,000 to $25,000. Step up to 6 kW with a 1,500 × 3,000 mm table and you are in the $60,000 to $150,000 range. A 12 kW machine with an automatic load and unload tower, enclosure and dust extraction passes $250,000 and can exceed $500,000.

Bed size comes second. Sheet metal shops standardize on 1,500 × 3,000 mm and 2,000 × 4,000 mm tables. A larger bed needs a heavier gantry, more linear rail, and a bigger frame to hold flatness. That frame is most of the cost. If your largest part fits in 600 × 400 mm, a large bed is wasted money.

The cutting head and motion system set the accuracy. A standard head holds ±0.05 mm to ±0.1 mm on 1 mm mild steel. A precision head with automatic focus, a capacitive height sensor and a granite or cast-iron base can hold ±0.02 mm. That accuracy costs money, but it is what separates a machine that cuts brackets from one that cuts medical housings.

Software and control matter more than buyers expect. A nesting package that handles remnant sheets and common-line cutting can drop material use by 5% to 15%. On a 100-sheet job that pays for itself. Controls with a real cut-parameter library save setup time on every new material. Ask which materials the parameter library already covers.

  Extraction and chillerOften left out of a quote, then added later at 10% to 20% of machine price.

Entry machines at 1 kW to 2 kW are built for sheet under 3 mm. You see these in sign shops, prototype labs and small enclosure work. Expect a bare machine with a basic head and manual sheet loading. Add a chiller, fume extraction and a nesting license, and the delivered cost is usually 15% to 25% above the listed price.

Mid-range machines at 3 kW to 6 kW are the workhorse of job shops. They cut 1 mm to 12 mm mild steel, 6 mm stainless and 4 mm aluminium at production speed. A 6 kW machine with a 1,500 × 3,000 mm bed, automatic focus and a two-pallet changer is the configuration most shops buy. This is the band where quoting gets competitive.

High-power machines at 8 kW to 12 kW are for thick plate and high-volume runs. Nitrogen cutting of 12 mm stainless or 20 mm mild steel becomes practical. These machines need a serious power supply, a large chiller and a crane or lift for sheet handling. Running cost per part drops, but the entry cost and the floor space are real constraints.

Above 12 kW, you are buying a production cell, not a machine. Automatic storage, robot loading and inline part sorting push the price past $500,000. That only makes sense when the machine runs two or three shifts and the part mix stays stable. For anything else, two 6 kW machines often beat one 12 kW cell on uptime.

Laser cutting removes material by melting it, so it cuts flat sheet and tube, not solid blocks. If your part is a 40 mm thick manifold with pockets on five faces, no laser will make it. That part goes to a 5-axis machining center. Laser cutting is a 2D process with a small cut width, usually 0.1 mm to 0.3 mm on thin sheet.

Thick plate is where the economics turn. Cutting 25 mm mild steel on a laser is possible, but the edge is rough, the cut speed is slow, and the part may need a secondary finish. A waterjet or plasma cutter can be cheaper at that thickness, especially for loose-tolerance plate. Laser wins when you need a clean edge and a tight profile on sheet up to about 12 mm.

Heat is the other limit. The laser leaves a heat-affected zone of 0.05 mm to 0.3 mm depending on material and speed. On hardened steel or a stress-relieved part, that zone can distort a thin web. If your part has a 0.5 mm ligament between holes, plan the cut sequence and add a stress-relief step, or move to wire EDM.

For prototypes, the choice is often laser plus machining. Cut the flat blank on a laser, then machine the holes, threads and mating faces. This is faster than milling the whole profile from solid and uses far less material. On a 200-part run, the laser blank pays for itself in material and cycle time.

Power draw is the smallest line. A 6 kW fiber source plus chiller and extraction pulls roughly 25 kW to 35 kW at full cut. At $0.12 per kWh that is $3 to $4 per hour. Idle draw is much lower, so keeping the machine on between jobs is not the big cost.

Assist gas is the biggest variable. Cutting 3 mm mild steel with oxygen is cheap. Cutting 6 mm stainless with nitrogen can consume 20 m³ to 40 m³ per hour. A nitrogen generator costs more upfront than bottled gas but drops running cost sharply if you cut stainless every day. Run the numbers on your actual gas bill before deciding.

Consumables are predictable. Nozzles, protective lenses and focus lenses wear, and a dirty lens ruins cut quality fast. Budget a few dollars per cutting hour and keep spares on the shelf. A machine down for a $30 lens is a bad trade.

Labor and floor space finish the picture. One operator can run two machines if loading is automated. Without automation, one operator per machine is normal. Add rent, insurance and the cost of scrap, and the true hourly rate is usually two to three times the power cost alone.
