Laser Cutting: When the

Dealing with air quality is not the fun or sexy part of lasering but it is definitely a critical factor in being safe and successful in our business! The process of laser cutting can release harmful particles and gases into the air, making proper ventilation essential for the safety of all!

Why is Ventilation Important?

During laser cutting, the heat generated by the laser can vaporize the material being cut, releasing fumes and particles into the air. These fumes and particles can include various chemicals and compounds, such as formaldehyde, benzene, and acrylic acid. Inhaling these particles can pose a health risk to those operating the laser cutter and anyone else in the vicinity.

In addition to the health risks, the buildup of fumes and particles can affect the quality of the laser cutting. The buildup can cause residue to accumulate on the lens, affecting the accuracy of the cuts, and can clog the ventilation system, leading to reduced efficiency and potential equipment damage.

What is Being Released in the Air After Cutting Each of the Following Materials?

The materials being cut with a laser can vary, and each material can release different particles and fumes into the air. Here are some examples of the types of particles and fumes that can be released during the laser cutting process for some common materials: Solid Wood: When cutting solid wood, the laser can vaporize the wood fibers, releasing particles such as formaldehyde, benzene, and other volatile organic compounds (VOCs*).

Plywood: Plywood is made by bonding layers of wood together, and the adhesives used in the process can release formaldehyde, a known carcinogen, into the air when cut with a laser.

MDF: MDF, or medium-density fiberboard, is a popular material for laser cutting. However, the resin used in the manufacturing process can release formaldehyde and other VOCs during the cutting process.

Cast & Extruded Acrylic: When cutting cast acrylic with a laser, the heat of the laser can vaporize the material, releasing fumes that can include acrylic acid, hydrogen cyanide, and other compounds. The fumes from extruded acrylic tends to be less toxic then the cast acrylic due to the manufacturing process and vapors can be highly flammable.

Leather: The laser cutting of leather can release fine particles that can cause respiratory irritation, and the fumes released can contain harmful chemicals.
