TL;DR

Best for
What makes this machine stand out
Hardware and workflow features worth understanding before you buy : not just wattage on a label.
Autofocus / height sensing (Z-style)
The machine measures material height (autofocus, LiDAR, or probe-style sensing) so the lens sits at the right distance before the job starts : you are not dialing focus by hand on every new thickness. Huge time saver on mixed scrap, warped boards, and CO₂ beds with varying acrylic sheets.
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.
Our verdict
Ideal if you
Monport GT 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
Cons
- Does not cut wood, leather, or acrylic: metal marking workflows only
- Fume extraction still matters for coated metals and marking sprays
