NXG 600Price$1,500,000 - $3,000,000
Browse 21 mid-power metal 3d printers (dmls/slm) from 10 manufacturers. Compare specifications, capabilities, and pricing. Pricing from $280,000 to $1,500,000.
The mid-power (4–8kw) segment contains 21 machines from 10 manufacturers, with power levels spanning 0.4kW to 6kW (average 1.5kW). This is the highest-volume segment for job shops and mid-size fabricators, offering the best balance of capability and operating cost. These machines handle the majority of commercial sheet metal work from 1mm to 20mm mild steel.
Chinese-origin machines account for 29% of this tier (6 of 21 systems). In the mid-power segment, differentiation comes from motion system quality (linear motors vs. rack-and-pinion), cutting head technology (auto-focus with collision protection), and integrated nesting software. Evaluate total cost of ownership over 5 years including consumables, maintenance, and downtime costs.

Selecting the right metal 3d printers (dmls/slm) involves evaluating five critical factors: (1) Material type and maximum thickness — determine the minimum laser power required. (2) Work area dimensions — match to your largest sheet or part size, with common formats being 3015 (3000×1500mm) and 4020 (4000×2000mm). (3) Production volume — high-volume shops benefit from automation features like sheet loading/unloading and nesting software. (4) Budget — consider total cost of ownership including installation, training, consumables, and maintenance, not just purchase price. (5) Service and support — verify the manufacturer has local service partners in your region. Use our comparison table above to evaluate 21 options side by side, filtering by the specifications most important to your application.
Five primary factors determine laser cutting edge quality: (1) Laser power and beam quality (BPP/M²) — lower BPP values produce focused spots with higher energy density for cleaner cuts. (2) Cutting head optics — auto-focus heads with collimation adjustment optimize beam characteristics for different materials and thicknesses. (3) Motion system accuracy — positioning accuracy (±0.03mm typical for premium machines) and repeatability directly affect dimensional precision. (4) Assist gas selection and pressure — nitrogen for oxide-free edges on stainless and aluminum, oxygen for faster thick-steel cutting. (5) Mechanical rigidity — machine bed flatness, gantry stiffness, and vibration damping affect edge straightness and surface roughness. Compare these specifications across our 21 listed machines using the table above.
