Laser-Cut Metal Files: Vector Detail, Min Bridge & Fiber Notes

Most CO2 hobby lasers can't cut metal — they can only mark anodized aluminum or coated metals. Fiber lasers cut metal cleanly but want different file rules: heavier bridges, larger minimum detail, and respect for heat-affected zones. Lazrit's metal profile sets a 1.5 mm thickness default, 3 mm minimum bridge, and 1.5 mm minimum detail. If you're marking rather than cutting, switch the mode to engrave and the bridge requirements drop away.

Cut vs mark

Cutting metal means physically separating the material — fiber lasers, plasma, water-jet. Marking means changing the surface color or texture without cutting through — CO2 lasers on anodized aluminum, fiber lasers in marking mode. Lazrit's cut-vs-engrave layer split maps naturally onto cut-vs-mark.

Recommended settings

These vary so much by alloy and machine that we won't quote numbers. The Lazrit file is the file; tuning belongs to your fiber laser's slicer.

How Lazrit prepares metal files

Trace, topology validation, auto-bridge — same pipeline, conservative defaults. If you're cutting stainless or aluminum, expect to add manual bridges in the heat-affected zones where a 3 mm width might not be enough.

Materials Lazrit does not support

We don't model fiber-laser kerf, beam compensation, or pierce points. Output an SVG and let your fiber slicer handle those.

Frequently asked questions

Can I use Lazrit for fiber laser cutting?

Yes — the SVG output is the input to most fiber slicers (e.g., LightBurn for fiber, EZCAD).

Does Lazrit handle pierce points?

No. Pierce points are a fiber-slicer concept; Lazrit's job ends at clean topology.

What about marking anodized aluminum on a CO2?

Set the layer to engrave, drop thickness toward 0.1 mm so the bridge logic doesn't apply, and export. The result is a single-layer SVG ready for LightBurn.

Is fiber-laser kerf compensated automatically?

Not yet. Kerf compensation is on the roadmap but not in current builds.
