AtomStack Kraft Review: Pros, Cons & Who It’s For

AtomStack Kraft review: the short verdict

The AtomStack Kraft is an enclosed dual-laser gantry engraver. Unlike modular laser systems that require purchasing and manually swapping separate toolheads, the Kraft houses both a 20W diode laser and a 1.2W infrared (IR) laser in one carriage. The 20W diode cuts dark opaque acrylic, leather, paper, and plastic up to 10 mm in one pass while engraving wood and stone. The 1.2W IR beam marks jewelry and bare metals. The listing notes that operators can switch laser sources at the press of a button, while also claiming both beams can fire at once.

The trade-offs are a substantial 72.8-pound bench weight, unstated cutting and engraving speeds on the listing, the physical inability of diode light to cut clear acrylic, and no warranty term stated on the listing.

Key specs

Specifications are manufacturer rated, as published on the AtomStack listing and collected 10 October 2026. AtomStack lists the diode output as 20 W (20,000mW) and the infrared output as 1.2 W (1,200mW), confirming both figures represent optical laser power rather than electrical input draw.

The machine

What the AtomStack Kraft does well

Two lasers without swapping modules

Many dual-source setups require detaching cables, swapping laser heads, and re-homing the machine between jobs. The Kraft houses both a 20W diode and a 1.2W infrared laser on the same gantry. The listing presents an internal contradiction on how the sources fire: it claims operators can use both beams at once for deeper results, but also states you press a button to activate another laser. Whether software allows combined firing or simply switches active sources, housing both beams eliminates manual module changes.

Class 1 enclosure and built-in safety

Open-frame diodes require workshop eye protection and aftermarket enclosures. The Kraft is listed as a Class 1 safety laser with an integrated protective enclosure. It includes door detection interlocks that pause the beam when opened, dual stops, operational status lights, and an automatic fire extinguisher. For home studios or educational settings, an enclosed chassis provides practical protection. Compare other options in our best enclosed laser engraver guide.

Camera alignment and autofocus

A built-in 16 MP HD camera provides workspace positioning rated to 0.5 mm (0.019 in) accuracy, reducing material waste on irregular blanks. An autofocus button sets the laser at the correct height without manual spacer blocks. The system supports AtomStack Studio and LightBurn across Windows, macOS, iOS, and Android, and can run offline without an active internet connection. Read our assessment of whether LightBurn is worth it.

Work area and air assist

The 50×32 cm (19.69 x 12.60 in) working area accommodates larger signs and batches. AtomStack rates the 20W diode to cut up to 10 mm (0.39 in) in one pass through dark opaque acrylic, plastic, paper, and leather. The included air assist clears combustion debris to keep cuts clean. Learn how airflow affects cut quality in our guide on does air assist make a difference.

Limitations

• Unstated speed ratings. The Amazon listing does not publish rated engraving or cutting speeds in mm/s or mm/min, making it difficult to project job run times before buying.
• Heavy benchtop footprint. Weighing 72.8 pounds with an enclosed gantry frame, the Kraft requires a dedicated, sturdy workbench and assistance to move safely.
• Acrylic wavelength restrictions. While rated to cut dark opaque acrylic up to 10 mm, blue diode beams pass directly through clear and light blue acrylic sheets. Cutting transparent acrylic requires a CO2 laser; see our diode vs CO2 laser guide.
• 1.2W infrared power limit. The 1.2W IR beam handles fine surface marks on metals and jewelry, but lacks the wattage for deep relief engraving or metal cutting.
• No warranty stated. The listing does not state a warranty term. Confirm coverage terms with the manufacturer before ordering.

The AtomStack Kraft starter bundle

The Kraft is sold as a complete starter package designed to run out of the box. The kit includes the enclosed dual-laser unit, the 16 MP camera, included air assist, a toolkit, and the user manual. Software access is covered via free AtomStack Studio downloads alongside LightBurn compatibility. Offline file execution allows importing standard formats including DXF, SVG, PNG, JPG, BMP, and GIF via direct connection. For makers starting fresh, having air assist and positioning hardware included avoids initial accessory add-ons.

AtomStack Kraft dual laser specs in depth

The Kraft dual-laser architecture pairs two distinct wavelengths in one footprint. The 20W (20,000mW) diode laser operates at a blue wavelength, which the listing rates to cut up to 10 mm (0.39 in) in one pass through dark opaque acrylic, plastic, paper, and leather, alongside engraving wood and stone. The secondary 1.2W (1,200mW) infrared laser operates at an infrared wavelength, coupling directly into bare metals and jewelry blanks without chemical marking sprays. While high-volume shops may prefer a dedicated fiber machine for rapid industrial cycles, the Kraft 1.2W IR laser provides hobbyists and personalized gift shops with accessible metal marking capability.

Who should buy it, and who should skip it

Buy it if you want an enclosed Class 1 desktop laser that handles wood engraving, dark acrylic cutting, and bare metal marking without changing toolheads, and you value built-in camera positioning, autofocus, and included air assist for home or classroom crafting.

Skip it if you need to cut clear acrylic, need rapid industrial metal production, or lack space for a permanent 72.8-pound machine. Explore alternatives in our best laser engraver for beginners and best laser engraver for small business roundups.

Alternatives

For dedicated bare metal marking at higher speeds, compare the standalone systems in our best laser engraver for metal and best fiber laser engraver guides. If cutting clear acrylic and thick wood is your primary goal, consider a home-friendly CO2 machine from our CO2 laser cutter for home use guide.

FAQ: lasers and CNC

What are the AtomStack Kraft specs?

A 20W diode laser and a 1.2W infrared laser, a 50×32 cm (19.69 x 12.60 in) work area, a 16 MP camera with 0.5 mm accuracy, autofocus, and air assist. It weighs 72.8 pounds and is rated as a Class 1 laser. Cutting and engraving speeds are not stated on the listing.

Can the AtomStack Kraft cut metal?

No. The 1.2W infrared laser is designed to engrave and mark bare metal and jewelry. Cutting metal requires significantly higher laser wattage and assist gas pressure.

Can the AtomStack Kraft cut clear acrylic?

No. The 20W blue diode beam passes straight through clear and light blue acrylic without heating it. Cutting clear acrylic requires a CO2 laser.

Is the AtomStack Kraft enclosed?

Yes. The Kraft features a built-in Class 1 enclosure equipped with door detection interlocks, status indicator lights, dual stops, and an automatic fire extinguisher.

Does the AtomStack Kraft require an internet connection?

No. The listing states it can run offline without an internet connection. It imports standard DXF, SVG, PNG, JPG, BMP, and GIF files via AtomStack Studio or LightBurn.
