Advanced Capabilities • Color Marking: Achieved by tuning pulse width and frequency on stainless steel and titanium • Deep Engraving & 2.5D: Short pulses facilitate deeper, embossed marking on metals Material Expansion: Works on hard plastics and painted materials Dimensions and Weight Summary • Base footprint: ≈336 × 555 × 635 mm (100 W model) • Weight range: 11 kg (20 W) to ~27.7 kg (30 W), ~22 kg (60–100 W) Summary & Choosing Tips If you plan on color marking or deeper engraving, lean toward the 60 W MOPA—it offers a strong mix of speed and versatility. The 100 W boosts cutting capacity (~3 mm metal), but adds weight and size. For lighter usage (jewelry, occasional marking), the 20 W or 30 W models remain capable yet more compact.
