Monport GA 100W MOPA: deep metal engraving and color effects
All Monport models →Add to compare →

Released September 2024
TL;DR
Monport GA 100W MOPA targets serious metal engraving shops needing deep marks and color on stainless. Industrial pricing and footprint: not a desktop B4-class galvo.
Best for
What makes this machine stand out
Hardware and workflow features worth understanding before you buy : not just wattage on a label.
Fiber metal marking
A fiber source marks bare and stainless steel without spray : the right tool for tools, jewelry, and industrial tags. It will not cut wood or acrylic; pair it with a diode or CO₂ if your shop needs organics too.
LightBurn compatible
LightBurn support means advanced layers, camera tools, and workflows many makers outgrow the stock app with. Confirm your exact controller board before assuming full features : some machines need a paid license separately.
Galvo speed class
Galvo mirrors move the beam instead of a heavy gantry : engraving speeds that feel instant on small fields. Trade-off: tiny work area versus a flatbed diode; ideal for jewelry, tags, and batch marking, not large signs.
Our verdict
Ideal if you
Monport GA MOPA Fiber 100W fits shops that mark stainless, aluminum, and tools daily without a CO₂ bay. A solid bench option for jewelry, tags, and small batches.
Skip if you
Skip if wood, leather, or cast acrylic pay your bills. Deep metal cutting and large industrial panels often need more fiber headroom or a different machine class.
Pros
- Fiber marks metal: does not cut wood or acrylic
- Software listed on the profile: test your workflow (LightBurn or maker app) on scrap first
- Work area Large marking field (verify SKU): confirm your typical job sizes fit the bed
Cons
- Does not cut wood, leather, or acrylic: metal marking workflows only
- Fume extraction still matters for coated metals and marking sprays
