Laser engraving is the art of using a powerful beam of light through optical magnification to leave stunning marks on hard surfaces, including ceramics, wood, and metal. The technique involves firing a high-energy beam of light at a targeted area to vaporize material and leave a permanently visible mark. Color changes can also be due to chemical reactions between the material and heat from the laser beam, foaming, charring or ablation.

The type of laser treatment depends on the material. On harder surfaces, such as titanium, the laser beam will ablate the surface. This means removing microscopic debris from the surface. By contrast, the beam burns through soft materials like wood and rubber.

Atomstack A10 Pro
The engraver is sold with five main components, packed in a small box. All the electronics are usually in one enclosure; you just need to unpack and reassemble the frame and connect the wires, power and data cables. Unless you've built a machine before, it takes about 45 minutes to read through the how-to manual and actually set it up. And because every wire and part is unique in design, you can't interchange connections or parts.

The frame and rods are made of high-quality steel, which is resistant to warping.

The machine runs on two quiet stepper motors. One is for the x-axis and the other is for moving the laser head along the y-axis. Focusing guides on the head move it along the Z axis, i.e. up and down according to the thickness of the material.

The A10 has two diode emitters instead of the one we often see in many atomstack laser engravers. The main diode points directly at the material. The other emitter is perpendicular to the main emitter, but as the beam bounces, the composite lens is tilted at a 45 degree angle. This bends the beam through a 90 degree angle, connecting the beam from the main diode. The result is a doubly powerful router.

With a 10W beam illuminating the surface, heat buildup is unavoidable. Luckily, a fan on top of the unit cools the area down.

The engraving machine is compatible with LightBurn and customized LaserBox Basics software, which receives data via USB data cable, Wi-Fi or TF card.

The Atomstack A5 Pro is a standard desktop engraver with a working surface area of approximately 252 square inches, a 5W module and a compression point. The compression spot houses several crystal-clear lenses that compress the coarse, weaker laser beam into a narrower but more intense beam. A more focused laser can easily tear through 0.5" thick wood. If you want a generous work area, the extension kit effortlessly extends the length from 21 inches to 33.5 inches.

In addition, the high-performance lightweight aluminum structure consisting of one-piece lead-screws flexibly forms the guide rail of the laser module. On a smooth pole, the laser module can cover 430 inches per minute. This impressive speed is useful when working on complex designs and time is not on your side.

The UV filtering acrylic on the laser module filters out up to 97% of UV rays making it safe for your eyes and skin. This feature also allows you to have a clear 180 degree view of what the machine is doing from above.

Finally, the Atomstack A5 is compatible with both Mac and Windows operating systems and software. You can use the free LaserGRB software or pay for an advanced design software called LightBurn. After coming up with a unique design, you can convert it to NC, BMP, JPG, PNG or DXF files. The machine has no problem with either of them.
