Gravotech - Fiber laser serie

FIBER Laser: Integrated laser marking system for metal and plastic parts

Our powerful and high-quality industrial Fiber Laser engraver performs precise markings quickly. Compact, with great communication links and simple to integrate in a manufacturing process, it is the perfect fiber laser marker for metal and plastics.


    The heavy-duty design, based on a cast aluminum structure, and high-quality optical components guarantee strength and low maintenance. Whether integrated in a production lines or robotic cell. The integrated laser implementation is easy in all mounting positions, the laser can be oriented to the part surface to significantly reduce installation times and tooling costs.
    Equipped to meet the needs of Industry 4.0, the fiber laser engraver for metal, can use many network and fieldbus protocols allowing full compatibility with all PLCs brands to ensure quick and cost-effective integration.
    This deep laser marking machine is available in several powers; 20W, 30W and 50W. 20W is adapted for most applications for surface marking, 30W is the solution for fast and high-contrast markings, and 50W is the most suitable solution for deep laser engraving.

    Looking for a simple & affordable laser marker? The Fiber ENERGY contains all core features necessary for basic applications.

Fiber laser serie

This metal marking laser machine is the laser marking system dedicated to harsh environments and deep laser engraving.

The robust cast aluminum housing is rigid, reduces vibration and resists shocks. The IP 54 protection rating of the head reduces long-term maintenance costs.

A metal mesh Dust filter on the source helps to protect the electronics and source.


To facilitate and reduce the programming times of your PLCs, the laser marker is compatible with a wide range of communication protocols:

  • Ethernet TCP/ IP, RS232
  • Standard 8 I / 80
  • Dedicated I/O via DB-37

and optional industrial communication protocols such as Profinet & Ethernet IP

Lasertrace : our marking and identification software

Developed by Gravotech and enriched by numerous application experiences, this software includes all the functions necessary for identification and traceability.

Easily mark your parts, with text, serial numbers,
logos.  Generate unique codes like Datamatrix, barcodes, QR codes, UID, GS1, and configure your variables, counters and shift codes.

Delivered with each marking laser, Lasertrace allows you to create your marking files in a few clicks.

Once the files have been transmitted to the control unit, your metal marking laser machine can operate on its own, or controlled by a PLC.
