The OMTech K40+ is a compact and affordable 40W laser cutter and engraving solution that’s ideal if you’re entering the world of laser fabrication or want to enhance your creative workshop without investing in large industrial equipment. With a 300 × 200 mm working area, this desktop‑class laser machine strikes a balance between capability and footprint—fitting comfortably into home studios, maker spaces, classrooms, or small business workshops where space is limited. Whether you’re a hobbyist exploring laser cutting for the first time or a small business owner producing custom products, the OMTech K40+ delivers precise cuts and detailed engravings on wood, acrylic, leather and similar materials.
What Features Does This 40W CO₂ Laser Engraving Machine Have?
The OMTech K40+ CO₂ laser machine packs several practical features designed for accessible and reliable laser cutting and engraving:

The K40+ laser cutter is capable of cutting and engraving materials such as wood, acrylic, leather, and certain plastics. It’s particularly effective as a laser wood cutter for hobbyists and small businesses, providing clean cuts and detailed engravings on wood and other non-metal materials.
Absolutely! The wood laser cutter capabilities of the K40 make it perfect for creating detailed engravings and smooth cuts on various wood types. This laser wood cutter is great for crafting custom designs on wood, whether for decorative projects, personalized gifts, or small business items.
Yes, the desktop laser cutter is compact and designed for easy setup, making it ideal as a home laser cutter machine. It fits conveniently on most workbenches and is perfect for personal projects, small businesses, or hobbyists looking for a reliable small laser cutter at home.
The K40+ laser cutter is a more affordable option compared to higher-wattage models, making it an excellent choice for beginners or those looking for a cheap laser cutter. Despite its lower power, it still performs precise cutting and engraving, ideal for projects that don’t require industrial-strength power.
The best wood for laser cutting is typically basswood, birch plywood (laser-grade), or maple, depending on the application. Basswood is ideal for light-duty projects like models and crafts because it cuts cleanly and is available in common laser-ready thicknesses like 1/16", 1/8", and 1/4". Laser-grade birch plywood is one of the most popular choices thanks to its smooth finish, minimal voids, and consistent results—it’s commonly used in thicknesses of 1/8", 3mm, and 1/4". For a more premium finish and stronger durability, maple is great for detailed engraving and cutting, though it requires more laser power, especially in 1/8" to 1/4" sheets. It’s important to choose woods with low resin and glue content to avoid excessive smoke or poor edge quality.
