Product Overview
UNMEI: A revolutionary Fiber marker and engraver.
Having the latest state of the art RE4 control electronics/software 100% made in the USA.
New Unique Patent Pending Features (2025)
- Whole Lens Correction (WLC) Technology — Edge-to-edge, pixel-accurate workspace capture using an external overview camera with FSL’s 256-point WLC calibration (vs. standard 4-point homography).
- FSL ZCam 3D Scan Technology — Built-in 0.1 mm accuracy depth scanning for click-to-autofocus anywhere in the field.
- Coaxial Camera with WLC (Optional) — Through-the-lens system using a dichroic mirror, captures 196 stitched images with WLC for ~10× higher effective resolution than standard overview. Shows exactly what the laser sees.
Optics & Imaging
- Dual Camera Option — Combine overview + coaxial views for precision alignment within ±2 µm.
- Focus Anywhere — Camera-based focus measurement anywhere in the marking field.
3D & Advanced Marking
- True 3-Axis Dynamic Galvo (Optional) — Advanced 3D surface marking with patent-pending “Saw” mode for defocus resilience.
- Full 3D Curved Surface Engraving — Upload STL/OBJ and wrap designs on cylinders, cones, spheres (no rotary needed).
- 3D Relief Engraving — AI converts 2D images to 3D OBJ for 3D engraving and or engrave true 3D files.

3D Scan-Mark with FSL ZCam Autofocus
FSL ZCam 3D Scan Technology maps millions of depth points to create a live 3D workspace. It enables simultaneous engraving across multiple objects of varying heights and supports automatic click-to-autofocus anywhere in the field. Using the ZCam depth map, objects outside a typical field of view are split and marked with synchronized Z motion for consistent results.
The Perfect Accessories
SYNCRO Rotary
Engrave curved objects with synchronized rotation — up to 100× faster than gantry systems.
Use ZCam to auto-measure diameter; ideal for tumblers, glassware, and more.
Capable of surface and subsurface glass marking up to 4" deep. Increase wattage for higher speed and depth.
Fume extractors, specialty focus lenses, and more.

Dual Coaxial Camera with Liquid Lens
Varioptic liquid lens with a dichroic mirror and high-speed camera enables precise through-lens viewing, while a second camera provides a large overview. The coaxial camera places the laser spot repeatably within ~2 µm, delivering ultimate real-world-to-laser calibration.
Motorized Linear Extension Rail Options
Available in 500 mm and 1000 mm lengths; mounts to the bed and slides under the galvo. Two modes:
- Repeat Job — Automatically make many copies in production.
- Continuous Engraving — Scan a single galvo line (Y) while the rail synchronously shifts for up to 300 mm × 500 mm (12" × 20") continuous jobs with no line breaks.
Applications
Explore engraving, marking, micromachining, and more across metals, plastics, glass, ceramics, and organics.
