🔥 All CO2 Laser Engraver Sent FREE Laser Marking Spray!

Faster and More Accurate
The newly customized galvanometer system is equipped with more expensive silicon material reflectors, allowing for a maximum speed of 10000mm/s. Monport has also customized an F-theta field mirror, which, together with the entire marking system, can achieve a carving accuracy of 0.01mm.
Just Right Working Area
For a 20W fiber laser, an area of 110*110mm is optimal, as excessive engraving area may result in poor engraving effect or even distortion.After special tuning by Monport, even when carving at the edges, there will be no weak light.
Deep Engraving and Cutting Capabilities
With this 20W fiber laser marking machine, you can perform 2.5D metal engraving, deep metal engraving, and even some metal sheet cutting (usually the higher the power, the stronger the deep engraving and cutting ability, and the higher the efficiency. If you want stronger and faster results, Monport recommends purchasing a 50W or above machine)
Rich Compatibility with Accessories
You can pair it with a rotary (marking circular objects), a smoke purifier (absorbing smoke and dust), a protective cover (noise reduction, safety), and all of which are sold in Monport stores.
