Product description

Power your biggest ideas

The AtomStack Kraft 40 W brings high-performance laser engraving and cutting to your workshop with a powerful 40 W diode laser for impressive capability and versatility.

Whether you’re creating detailed signage, custom gifts, or professional prototypes, the Kraft 40 W delivers precision, strength, and ease of use to every project.

Key features

High-power laser, broad material reach

Equipped with an advanced 40 W diode laser, the Kraft cuts and engraves a wide range of materials: from thick wood (up to ~18 mm) to dark acrylic (up to ~15 mm) in a single pass, delivering clean cuts and crisp edges.

This power level lets you handle wood, acrylic, leather, plastics, and more without switching modules or tools, giving you more flexibility for creative and professional workflows.

Large workspace & workflow efficiency

The spacious 50 × 32 cm work area lets you cut or engrave big pieces or batch-process multiple smaller parts at once. With the optional conveyor feeder, you can expand your workspace even further (80 × 50 cm).

Efficient workflow features and autofocus tools keep setup time low and productivity high.

16 MP camera preview

The 16 MP HD camera, with 0.5 mm accuracy, ensures that you are not wasting materials or time on uncalibrated items.

This integrated HD camera simplifies aligning and previewing your work area, ensuring precise placement of your designs every time.

With the AI-powered software, batch engraving is even more efficient as it positions the images on the objects automatically.

Batch engraving

With the batch engraving function, the AtomStack Kraft 40 W lets you process multiple items in a single, streamlined setup.

Simply place your materials on the workbed, position your designs on the screen, and the machine handles the rest. This feature dramatically boosts your efficiency, saving you time, reducing errors, and ensuring every item is engraved with perfect consistency. It’s the ideal solution for scaling up production or running large-batch custom orders.

Automatic resume

Automatically resume your project from the last position after a power outage. The Kraft laser engraver remembers the exact coordinates of the laser head and the progress of your job.

Flame extinguishing air pump & air assist

The air extinguishing air pump on the AtomStack Kraft is a two-in-one system. As a standard air assist, it provides a powerful stream of air that gives you cleaner cuts and fewer burn marks. It also acts as a crucial safety feature: if the machine's sensors detect a flame, the pump automatically extinguishes the flame giving you peace of mind.
