14W+ CNC Laser Upgrade

An ideal starter laser for engraving and light cutting

The 14W+ Laser is a versatile, budget-friendly upgrade that opens the door to a wide range of CNC laser applications. Designed for makers who want excellent engraving detail with the ability to cut light, non-dense materials, the 14W+ delivers impressive performance without the complexity or cost of higher-power systems. It’s a perfect first step into laser work for hobbyists, small shops, and educators alike.

What You Can Make

The 14W+ excels at both detailed engraving and light cutting, making it ideal for everyday laser projects such as:

• Engraving on wood – signs, plaques, cutting boards, and artwork
• Light cutting – cardboard, balsa wood, 1/8″ birch plywood
• Dark acrylic – clean cuts and crisp engravings on 1/8″ material
• Decorative projects – ornaments, inlays, and craft components

Its fine laser spot produces sharp text, detailed graphics, and smooth gradients, making it especially well-suited for photo engraving and precision work.

Built-In Air Assist – Use It When You Need It

The 14W+ comes standard with air assist, giving you flexibility depending on the task:

• Install air assist for cutting to reduce charring, improve edge quality, and keep the lens clean
• Remove air assist for engraving when maximum detail and contrast are desired

This simple setup lets you optimize results without changing tools or hardware.

Excellent Resolution, Easy to Use

Despite its approachable price point, the 14W+ delivers excellent engraving resolution thanks to a well-focused beam and stable optical design. It’s powerful enough to be productive, yet forgiving enough for users who are new to laser work. Pair it with popular software like LightBurn and you’re engraving confidently in minutes.
