Product overviewThe Gravotech LW3 is a Class 1 industrial laser workstation designed for direct part marking of large and heavy components. Compatible with Fiber, MOPA, Hybrid/DPSS and Green sources, the LW3 combines a large internal envelope (up to 628 mm height) with automation and operator-safe enclosure for high-precision marking in production environments.
Key benefits- Large marking capacity: standard marking area 300 x 300 mm, ZX bridge option extends X stroke to enable effective marking up to 875 x 300 mm; internal clearance to accept tall parts (approx. 628 mm).
- Multi-technology compatibility: supports Fiber, MOPA, DPSS/Hybrid and Green lasers to mark metals, plastics and varied surfaces; suitable for DPM, serialisation and multi-level engraving.
- Production-ready design: integrated 7" touchscreen for local job selection, automatic three-sided door with safety sensors, optional trolley for mobility and fixture-friendly metal positioning table.
Highlights- ZX bridge option to extend effective marking area and X stroke.
- Motorized Z axis (standard 295 mm stroke; 575 mm with ZX) and programmable positioning.
- Automatic 3-sided door: closes at cycle start and reopens on completion; protected observation window for visual monitoring without protective eyewear when safe.
- Optional 3D marking module for sloped or angled surfaces.
- Designed for integration with exhaust/filtration systems for fume and particle extraction.
Typical applications- Traceability and DPM on large industrial parts (automotive, aerospace, heavy equipment).
- Permanent identification: serial numbers, 1D/2D codes (DataMatrix), batch marking and logos.
- Customization and medium-batch production requiring multi-position or multi-level marking.
