OMTech 13oz Laser Marking Spray for CO2 Engravers
The OMTech 13 oz laser marking spray produces high-contrast, permanent black designs on bare metals when used with 25W+ CO2 engravers or more vivid results with a fiber laser. The formula starts white and darkens to black after laser exposure, allowing clear workflow previews. It works across metals such as aluminum, stainless steel, and brass, enabling applications from jewelry personalization to tool serialization. The 13 oz can includes a clog-proof nozzle for even coating on surfaces, resulting in a thin, smooth layer that supports precise engraving.
xTool Black Laser Marking Spray 2.0
The xTool Black Laser Marking Spray 2.0 delivers permanent, high-contrast black markings on various surfaces, including metals, ceramics, and glass. The formula is upgraded for non-corrosive, fade-resistant marks suitable for lasting engravings. Usage requires shaking the bottle to loosen the powder, then applying with a side-to-side motion to avoid vertical shocks. It is compatible with a wide range of laser engravers, including CO2, fiber, and diode systems from multiple brands, enabling versatile setups for professionals and hobbyists alike.
OMTech 8oz Laser Marking Spray
This 8 oz OMTech spray provides high-contrast black designs on bare metals for 25W+ CO2 engravers and fiber lasers, with the white-to-black transformation after laser exposure. Its 8 oz size is ideal for smaller batches or fieldwork. The product emphasizes broad metal compatibility—aluminum, stainless steel, and brass—supporting tasks ranging from jewelry accents to serializing tools. The can is designed to deliver a consistent, smooth coating that complements meticulous engraving processes.
OMTech 2 x 13oz Laser Marking Spray Bundle
This bundle features two 13 oz cans of OMTech laser marking spray, designed for ongoing marking workflows. The formula creates high-contrast, permanent black markings on bare metals when used with CO2 engravers of 25W or higher. It also remains effective for more vivid results with fiber lasers. The dual-can setup supports larger projects, serializing runs, or batch processing while maintaining even spray deposition and a smooth coating on metal surfaces.
CO2 Galvo Laser Engraver Laser Marking Machine – 30W
This CO2 galvo laser engraver offers a 30W laser with a 140×140 mm marking area and D80 rotary axis, designed for rapid, precise marking and engraving of non-metallic materials such as wood, glass, acrylic, and rubber. While primarily a general-purpose laser, it complements metal marking workflows when paired with compatible marking fluids for certain substrates. The system emphasizes a class 1 safety enclosure and a robust galvo setup from SINOGALVO/ZBTK components, suitable for workshops needing quick turnaround times and repeatable results.
OMTech K40+ 45W CO2 Laser Engraver
The OMTech K40+ 45W CO2 laser delivers powerful performance for home and small business use, with an upgraded 45W laser that handles acrylic and wood with increased depth and cutting speed. It includes 2 years of global support with local demos by appointment, a feature set aimed at ensuring reliable operation and practical on-site assistance. The machine is compatible with popular software ecosystems like LaserGRBL and LightBurn, enabling straightforward workflow integration for seasoned users and newcomers alike.
TEN-HIGH 50W CO2 Laser Marking Machine
The TEN-HIGH 50W CO2 laser is positioned as a higher-capacity option for faster engraving and marking, featuring energy efficiency and a galvanometer-assisted pathway. It is designed for reliability and faster throughput, with a focus on performance improvements over earlier CO2 models. This option appeals to small industrial setups and makers seeking stronger output for multi-part marking workflows while maintaining manageable operating costs.
OMTech Laser Marking Powder – 4.1 Fl. Oz.
OMTech Laser Marking Powder provides a cadmium-free alternative for metal marking. By applying a marking powder and adding alcohol, users create precise, durable marks on aluminum, stainless steel, brass, and other metals. It dries quickly—under five minutes in standard conditions, or about two minutes with a hot air blower—facilitating efficient batch production. This option supports projects that prefer powder-based marking processes alongside spray fluids for versatility in metal finishing.
Buying Guide: Key Considerations And Comparisons
- Material compatibility: For metal marking, verify whether your metals (aluminum, stainless steel, brass) are supported by the marking agent and ensure the laser power aligns with the substrate.
- Laser compatibility: CO2, fiber, and diode lasers vary in marking results. Marking fluids and powders may require specific laser types or settings to achieve high-contrast, durable outcomes.
- Coating application: Consider can size, nozzle design, and coating uniformity. Clog-proof nozzles help maintain consistent results across batches.
- Safety and handling: Some marking agents include powders or solvents; ensure proper ventilation and personal protective equipment for operator safety.
- Workflow compatibility: If you use multiple machines, prioritize marking sprays that perform across CO2 and fiber lasers to maximize flexibility.
- Maintenance and support: Brands offering global support and service plans help minimize downtime, especially for small businesses or shop-floor environments.
- Cost per mark: Compare bottle/pouch costs against yield and drying times. Powder-based options may require additional preparation steps but offer certain advantages in dry times and shelf life.
- Safety certifications: For classroom or workshop settings, ensure equipment meets local safety guidelines and class 1 enclosure requirements where applicable.
