The atomstack air assist option directs a stream of compressed air or gas onto your material, primarily to remove fumes generated during laser cutting or engraving, prevent the fumes from causing laser energy attenuation, ensure laser energy stability, and enable your engraving/engraving Cut pieces for best results.
There are many different styles of air assist, the two most common being "conical", which directs compressed air perpendicular to the material and directly down the cut, or "tubular" that directs air down the cut. An angle towards the rear of the machine.
There is also an air curtain design where compressed air is drawn from the bottom of the X-axis frame through small holes, creating an air curtain effect across the width of the work area. Each type has its own advantages - the cone style minimizes residue on the surface and provides a cleaner finish, especially on wood, and since the cone covers the bottom of the lens, it also provides a little extra protection of.
The downside of the cone is that you have to use compressed air 100% - even during engraving - or you can damage the lens. Also, during cutting/engraving, there is limited clearance between the bottom of the cone and the material, so if your material is not flat or the part slopes up during cutting, there is a higher risk of collision or difficult to engrave into recessed areas.
With a barrel style, it provides extra clearance for engraving and cutting uneven materials or recessed areas, and allows easy inspection and cleaning of the lens without removing any parts. There is also no need to use air assist during the engraving process, which provides cleaner results in most engraving applications.

Laser engraving is a popular option that provides a permanent and legible marking on an object through etching, ablation, or deep laser engraving. It is similar to laser marking, but the resulting appearance differs due to the depth of laser penetration.
Laser engraving is commonly used to create permanent serial markings on substrates made of: Metal, Wood, Plastic, Leather.
Benefits Of Laser Engraving Over Traditional Processes
Compared to manual engraving:
Minimally Invasive: Laser engraving can be performed at a range of depths without any direct contact at all. Surface marks can even be done on stainless steel with no depth. Overall, lasers are less damaging than manual engraving and keep the substrate material’s physical integrity intact.
Precise: Lasers provide a level of control that’s impossible to achieve manually. Compared to hand-engraving, the process is swift, clean, and highly repeatable, with little room for human error.
Versatile: A single laser engraving machine can be used to create a host of different designs with only minimal calibration. They can also produce exceptionally complex patterns.
Affordable: On average, laser devices last longer than other engraving machines and require less maintenance, resulting in savings that can be passed along to the consumer.
Fast: Lasers can be programmed to render virtually any design in a matter of moments. Because the process is automated, it’s easy to scale production runs as needed according to demand.
Long-Lasting: Laser-engraved designs are permanent but can wear over time, depending on the substrate material that’s used. Soft metals, for example, may experience more signs of wear than hardwood. In general, however, laser-engraved designs tend to have a longer lifespan compared to other engraving methods.
