OMTech Laser Marking Spray, 13 Oz
OMTech’s laser marking spray provides a practical option for achieving high-contrast, permanent black designs on bare metals when using 25W CO2 lasers or higher, with improved visibility when paired with fiber lasers. The formula starts white and turns black after engraving, making it easy to monitor the marking process. It supports a broad metal range, including aluminum, stainless steel, and brass, enabling personalization for jewelry, tumblers, and serialized tools. The 13-fluid-ounce can includes a clog-proof nozzle for an even, thin coating that yields consistent results across large or repetitive runs.
When integrating into a workflow, users can expect sharp, durable marks suitable for product branding, serial numbering, and custom artwork on metal surfaces. The combination of broad compatibility and a user-friendly spray mechanism makes this option appealing for shops handling small to medium batch runs, or for hobbyists scaling to more frequent production.
Key Specifications
- Compatibility: Bare metals including aluminum, stainless steel, brass
- Color Change: Appears white before engraving, turns black after laser exposure
- Volume: 13 fl oz
- Best use: CO2 engravers at 25W+ or fiber lasers for stronger results
GWEIKE G2 Max 50W Fiber Laser Engraver
The GWEIKE G2 Max blends speed and depth with a 50W fiber laser, delivering engraving up to 15000 mm/s and accuracy near 0.001 mm. Its deep engraving and metal-cutting capabilities enable high-value works across jewelry, tags, and industrial components. A larger 150×150 mm work area supports more substantial items, while an electric lift column simplifies focus adjustment, reducing manual setup and increasing workflow efficiency. This model is ideal for businesses seeking fast, precise metal marking with scalable production potential.
Performance notes include HD engraving resolution and deep engraving depth suitable for intricate logos or embossed effects. The combination of speed, depth, and a portable-like form factor helps studios and workshops optimize throughput without sacrificing detail. Operators should consider ventilation and maintenance needs typical of fiber laser systems and proper material compatibility checks for optimal results.
Core Benefits
- High-speed galvanometer with 0.001 mm accuracy
- Deep engraving and metal cutting with a 50W laser
- 150×150 mm working area with electric lift column
xTool F1 2-in-1 Dual Laser Engraver
The xTool F1 2-in-1 model combines a 2W infrared laser for metals with a 10W diode laser for non-metals, enabling rapid vector engraving on metal items and broader material versatility. With speeds up to 4000 mm/s, it supports batch processing for items like business cards, dog tags, jewelry, and tumblers. The fully enclosed design reduces smoke and odor, and an integrated air purifier (sold separately) further enhances user comfort during operation. It weighs about 4.6 kg, making it portable for craft shows or on-site engraving.
Key considerations include the trade-off between dual-wavelength capabilities and overall system power versus dedicated high-power fiber systems. This model suits hobbyists expanding into small business or educators seeking a compact, versatile tool with reputable software compatibility and a lower barrier to entry.
Notable Points
- Dual laser system for metals and non-metals
- Portable, enclosed design with dust and smoke mitigation
- Compact 4.6 kg with easy setup for events
OMTech Laser Marking Spray, 8 Oz
This 8-ounce OMTech laser marking spray offers a compact option with a clog-proof nozzle that distributes a fine, even layer across bare metal surfaces. Like the larger 13 oz version, it enables high-contrast, permanent black marks when used with 25W+ CO2 lasers or more vivid effects when paired with fiber lasers. It supports a broad metal range and is suitable for serializing tools, personalizing tumblers, and jewelry engraving. The smaller can is ideal for small studios, fieldwork, or trials before committing to larger volumes.
Operational guidance suggests testing on scrap metal before full production runs to calibrate spray thickness and laser settings for consistent results across batches. The spray’s color transformation and surface adhesion characteristics make it straightforward to assess engraving progress and final appearance in real-time.
Essentials
- 8 oz can size for compact use
- Wide metal compatibility and black-marking on laser exposure
- Coating delivers smooth, even coverage

Buying Guide: Key Considerations For Metal Laser Marking
- Materials and compatibility: Identify metals you’ll engrave most (aluminum, stainless steel, brass) and ensure the machine supports those substrates reliably. Consider whether you also need to mark plastics or wood with a dual-wavelength system.
- Laser type and power: Fiber lasers offer deep engraving and fast throughput on metal; CO2 and CO2-plus marking sprays provide versatile options for contrast on bare metals. Higher wattage typically yields faster results and deeper marks, but may require more robust ventilation and maintenance.
- Engraving speed and precision: Look for machines with high engraving speeds and repeatable accuracy (often in the 0.001 mm range for professional devices). A larger work area supports bigger parts, while an electric focus or lift column can reduce manual adjustments and improve workflow.
- Software and workflow: Confirm compatibility with common design formats (PLT, DXF, SVG, AI). Lightburn compatibility is a plus for some devices, and built-in controls should match your team’s skill level.
- Ventilation and safety: Ensure proper fume extraction and eye protection, especially for enclosed CO2 and fiber laser systems. Consider devices with smoke suppression features to maintain a clean workshop.
- Maintenance and consumables: Marking sprays require periodic replacement and proper storage. Fiber lasers demand regular alignment checks, while CO2 systems require tube and mirror maintenance. Budget for ongoing consumables and service plans.
- Portability vs. production scale: Portable or compact models suit events and small studios; larger, fixed systems excel in high-volume production. Choose based on space, throughput needs, and upgrade prospects.
- Price vs. performance: Weigh initial investment against potential productivity gains, material mix, and expected job mix. Reliability, support, and warranty terms should factor into the total cost of ownership.
Across these options, selecting a laser marking solution for metal hinges on aligning material types, desired mark quality, and production pace with your budget and workspace constraints. Whether you prioritize ultra-fast fiber engraving, portable versatility, or easy-to-use marking fluids for metals, the right combination can streamline branding, serialization, and customization across metal products.
