What 30 W does better
The current ComMarker B6 MOPA page lists a 30 W tier for color marking, engraving and deep-engraving research. It is the lower-cost and lower-power choice when the exact finished-part acceptance and cycle target pass.
Normalize lens, enclosure, extraction, fixture, software and support before attributing a quote difference to power.
What 60 W does better
The same official page positions its 60 W tier for color marking, engraving, deep engraving and selected metal-cutting research. Higher average power can offer depth or cycle headroom, but only an exact timed sample establishes the useful gain.
Treat cutting as exact-material and exact-thickness evidence, not a general sheet-metal capability.
Limitations of 30 W
A 30 W configuration may require too many passes or too much cycle time for a qualified depth target. That cannot be determined from source watts alone.
A smaller field can increase energy density while reducing part coverage. Qualify the quoted optical package.
Limitations of 60 W
The 60 W premium is wasted when 30 W already passes. More power cannot identify an alloy, fix a weak fixture, create process control or make a marketing color repeatable.
Open-format systems still require a controlled-area assessment, guarding decisions and contaminant controls. Do not trade away safety for source power.
Who should choose each—or neither
Choose 30 W when matched finished-part evidence passes at credible capacity. Choose 60 W when the same test proves valuable depth, cycle or process headroom after its complete cost is included.
Choose neither when the alloy, mark specification, lens, sample method or controls are unresolved. A conventional fiber or specialist UV process may be the better fit.
The official B6 MOPA configurations were rechecked 9 Sep 2026. Vendor category claims are not EtchCompass throughput tests.
