OMTech Spray vs GWEIKE Engraver
laser type
These products use fundamentally different technologies for marking. The G·WEIKE G2 Max is a standalone 50W fiber laser machine that emits 1064nm light. This type of laser is designed for deep engraving and cutting on metals, as well as marking on plastics and ceramics. In contrast, the OMTech item is not a laser machine at all. It is a 13 oz aerosol spray can intended for use with existing CO2 laser engravers. It acts as a consumable coating to help create black marks on bare metals like aluminum or stainless steel. You are comparing a complete hardware unit against a chemical accessory.
laser power
Power specifications define the intensity of the marking process. The G·WEIKE G2 Max delivers a substantial 50W (50,000 mW) of laser power. This high output allows for rapid engraving speeds up to 15,000 mm/s and the ability to cut through metal or create deep engravings. The OMTech product has no laser power rating because it is a marking spray. It relies on the power of your existing CO2 laser, which must be 25W or higher to work effectively with the spray. The G·WEIKE unit provides its own high-power source, while the OMTech spray depends entirely on an external machine's capabilities.
compatible material
Material compatibility determines what surfaces you can work on. The G·WEIKE G2 Max is built for a wide range of materials. It effectively engraves metals such as stainless steel and titanium, creating over 90 colors. It also works on plastic, leather, dark glass, colored ceramics, acrylic, and stone. The OMTech spray is strictly limited to bare metals. It is designed specifically for aluminum, stainless steel, and brass to create high-contrast black marks. It does not work on plastics, wood, or glass. If you need to mark non-metal items, the G·WEIKE machine is the only viable option here.
working area
The size of the workspace affects the dimensions of your projects. The G·WEIKE G2 Max features a dedicated working area of 150 by 150 millimeters. This space is supported by an electric lift column for easy focus adjustment. The OMTech spray has no fixed working area because it is a handheld aerosol can. You apply it to whatever object you place under your existing CO2 laser. The spray can itself has dimensions of 2.6 inches by 2.6 inches by 7.9 inches. The G·WEIKE provides a defined, automated workspace, while the OMTech spray offers flexibility for various object sizes.
software compatibility
Software integration streamlines your workflow and design transfer. The G·WEIKE G2 Max supports GLaser and LightBurn software. It connects via Wi-Fi and USB, allowing you to transfer designs from computers or smartphones easily. It also accepts various input file formats. The OMTech spray does not involve any software. It is a physical marking agent that requires no digital connection or file transfer. You simply spray the metal, engrave with your CO2 machine, and wash off the excess. The G·WEIKE offers digital control and connectivity, while the OMTech spray is a purely manual, analog process.
