Thanks to its ergonomic design and reduced dimensions (810 x 500 x 250 mm), this desktop CO2 laser cutter easily adapts to home, educational, or entrepreneurial environments, without sacrificing professional results. OMTech has included a powerful air assist that optimizes cutting quality, removing debris during the process and facilitating cleaner and more defined engraving lines.

One of the great differentiating factors of the K40 Plus is its adjustable mirror system, which allows for precise alignment of the laser beam path, ensuring a uniform distribution of energy, which noticeably improves the engraving precision in any area of the surface. This feature is fundamental for maintaining the consistency and accuracy of the work, especially in tasks that require high definition.

The inclusion of an industrial honeycomb cutting bed not only improves airflow and smoke evacuation but also reduces the contact of the material with the base, preventing burns, scratches, or unwanted marks. This promotes a cleaner and safer engraving environment, increasing the final quality of each project.

The adjustable height laser head offers a 30 mm range, allowing for quick adaptation of the beam focus to different material thicknesses. This versatility ensures a constant and uniform engraving depth regardless of the type of surface.

The enlarged viewing window, made of fireproof polycarbonate, allows for clear and continuous observation of the engraving process, while also protecting against laser radiation and heat. This provides safety without sacrificing visibility, making the monitoring and adjustment of ongoing work more efficient.

The K40 Plus laser engraver is equipped with a digital power and temperature control panel, which allows for precise regulation of both parameters, reducing the risk of overheating and increasing the lifespan of the equipment. In addition, it complies with CE standards and is classified as a class 1 laser, incorporating safety mechanisms such as an interlock system, emergency stop button, water flow control, and key switch.
