50W 3D Relief Laser Marking Machine for Precision Metal Engraving
Manufacturers that need more than flat logos and serial numbers require a laser system capable of controlling focus across depth. The DF3D-50W combines a 50W, 1064 nm fiber laser with a three-dimensional dynamic focusing and galvanometer scanning system. It is designed for precision marking, layered relief patterns, deep engraving, and processing across different surface heights.
3D Dynamic Focusing for Complex Designs
Conventional 2D marking systems work best on a fixed focal plane. The DF3D-50W can switch between 2D and 3D processing modes. Its software can fit artwork to an STL model, divide a relief design into layers, and generate tool paths for high and low surfaces.
This makes the machine suitable for decorative metal panels, hardware, precision instruments, automotive parts, molds, nameplates, electronic components, and customized craft products. It supports common files including STL, DXF, PLT, PCX, BMP, SHX, and TTF.
Technical Performance for Industrial Work
The system offers a maximum linear scanning speed of 7,000 mm/s, minimum line width of 0.015 mm, minimum character height of 0.3 mm, and repeat positioning accuracy of ±0.01 mm. The specified laser beam quality is below M² 1.3.
Two example lens configurations are available: a 100 × 100 mm marking area with a 40 mm Z range, and a 160 × 160 mm marking area with a 60 mm Z range. Lens selection should reflect part size, detail, and relief depth. A single engraving pass is specified at up to 0.05 mm; deeper relief is built through controlled multi-layer processing.
Layered laser processing creates detailed relief patterns on compatible metal parts.
Designed for Practical Production
The air-cooled system uses approximately 1.2 kW of whole-machine power and does not require routine laser consumables. Its manual precision lifting structure accommodates products of different heights, while dynamic focusing corrects focus across the selected processing range.
Buyers should test actual materials and artwork before ordering. Relief quality and cycle time depend on the alloy, target depth, marking area, hatch strategy, and surface finish. Fume extraction is recommended for processing dust.
ForwayLaser can evaluate customer samples to confirm lens selection, engraving depth, finish, and expected processing time. View our laser marking machines or contact us for a sample test.
FAQ
Can the DF3D-50W engrave curved or uneven surfaces?
Yes. Dynamic focusing is designed to follow different heights within the available Z range. Actual geometry should be confirmed through sample testing.
What materials can it process?
The 1064 nm fiber laser is mainly intended for metals and can also process certain compatible plastics. Results vary by material and surface treatment.
Is 50W enough for deep relief engraving?
The system supports layered relief processing, but total depth and cycle time depend on the material, artwork, and finish requirement.
