A 30W fiber marker built around a galvo head that can be lifted off its column and used handheld, which is unusual at this price. Two lenses ship in the box, a small one for fine detail on rings and pendants, a larger field for tumblers and tool panels. It marks stainless, brass, aluminium, titanium and anodised finishes, and with enough passes it will engrave deep enough to feel with a fingernail.

The target buyer sells personalised metal: knives, flasks, jewellery, industrial tags, serial numbers. It is the wrong tool for wood signage or acrylic cutting, since a fiber source does not cut sheet material. Fumes from metal marking are fine particles, so an extractor is not optional, and the safety glasses supplied must actually be worn. LightBurn support keeps the workflow familiar.

Pros

  • Marks steel, brass, aluminium and titanium
  • Two lenses included for detail and large parts
  • Head detaches for handheld marking
  • LightBurn compatible out of the box
  • Arrives assembled and calibrated

Cons

  • Cannot cut wood or acrylic sheet
  • Fume extraction required for metal dust
  • Small marking field per lens
  • Software learning curve for galvo settings
