6 Essential Safety Gears and Tools for Laser Cutting

5. Masks

A wide choice of filter masks are available to protect against the effects of hazardous substances present as powders. A simple paper element filter will be effective at removing almost all dust particles, as long as the mask is close-fitting and face sealed. The mask must preferably have an outflow valve to prevent the act of exhaling from lifting the mask and potentially allowing contamination past the face seal. If volatile, smoke, or sub-micron particulate particles are present, then a filter mask that integrates both particulate and adsorptive elements (such as an activated carbon filter element) is a better choice. This will reduce the potential exposure of very vulnerable tissues to unknown and unmeasurable toxicity. Life-threatening consequences of such exposures can be long delayed, so an assumption of high risk is a logical position.

6. Hearing Protection

Some large laser cutting machines can produce irritant noise levels, although these are rarely harmful. Experience with a machine will allow a personal choice to be made about this safety-gear option—but an assumption of risk is advised. 

Non-use of safety gear when using laser cutters can cause significant problems such as health issues and fire risks. Dust, volatiles, and combustion products present the most pernicious and potentially long-term harm to machinery users. Many materials can produce respiratory inflammation and irritation. Combustion products in particular can be carcinogenic and toxic. Additionally, laser cutters are among the class of machine that creates a greater fire hazard by cutting and combustion. It is recommended to follow all safety precautions stated by the OEM.

What Is Laser Cutting?

Laser cutting uses the ablation by melting or charring of material by laser light. It makes narrow cuts using a focused and coherent beam of typically UV radiation following a controlled path to “extract” parts from a sheet/block of material. The removed/destroyed material exits the cut either as char, vapor, or melted droplets, usually assisted by an air current. Additional cutting performance can be achieved by an aggressive nitrogen assist to clear debris, or an oxygen assist to oxidize melted materials (usually metals) to speed up the destruction of the cut pathway. Laser cutting is widely used in various industries including: automotive, medical, jewelry, metalworking, and woodworking. Laser cutters help produce car components, pacemakers, intricate jewelry, pipes, and types of furniture.

What Are the Dangers of Laser Cutting?

The dangers associated with laser cutting are essentially twofold: universal dangers in the use of machine tools and thermal-based cutting processes and laser-specific safety hazards. Some examples of dangers with machine tools and thermal-based processes are: smoke, vapor, and particles in the air, fire risks from hot cutting, moving-equipment hazards (impacting, pinching, or trapping a person), and electrical hazards from faulty wiring. Laser-specific safety hazards include extreme danger to the eyes due to the coherent light and highly concentrated radiation that can cut fast and deep into skin and tissue.  

What Are Some Laser Cutting Safety Tips?

Some laser cutting safety tips are listed below:

1. Never operate the laser cutting equipment unattended.
2. Keep the table and the work area clean.
3. Use all provided and recommended safety equipment.
4. Use interlocked, laser-proof covers when available. Use a non-interlocked screen at least.
5. Keep a fire extinguisher on hand and ensure it is within its use date.
6. Precautionary “warning, laser light” signs are not required for home equipment, but are advisable in shared areas.
7. Ensure good ventilation in the workspace and vent air extraction outside.

For more information, see our guide on Laser Cutting Safety Precautions.

What Are the Things To Avoid When Laser Cutting?

The things to avoid when laser cutting are listed below:

1. Don’t assume the process is safe just because the hazards are not clear.
2. Don’t bypass safety features like cover interlocks.
3. Don’t vent cutting gases/smoke into the workspace.
4. Don’t fail to act when a hazard is identified.
5. Don’t operate messy equipment; clean up first.
6. Don’t operate potentially faulty equipment; check and repair first.
7. Don’t closely watch the cut point without good-quality eye protection.

Are There User-Friendly Laser Cutting Machines?

Yes, there are user-friendly laser cutting machines. Laser cutting machines range from very low-power desktop devices with no cover and no “user protection” features, through mid-range machines with good safety features, up to immense industrial machines that pose life-threatening risks and require very careful and experienced supervision.

Selecting a laser cutter is first a functional decision. The choice between prioritizing function or safety often comes down to budget. The lowest power and simplest machines are designed for home use, so they’re specifically designed for the less experienced user and they’re made to be easy to operate. The Laser Pecker 2 laser engraver is a low-cost, open-frame machine. But it’s easy to use and quick to set up. In the mid-range, machines have more power and usually an enclosure that makes them safer. The Glowforge® and xTools M1 are good options that are widely appreciated as being easy to use.

Is Laser Cutting Harmful to the Human Body?

Yes, laser cutting is harmful to the human body. The use of safety gear when using laser cutters is essential. The risks to the operator and others in the machine environment are significant but very manageable. Productive activities are virtually never without risk, so the key with laser cutters, as with any tools, is to stick to good practices and avoid hazardous behaviors.

You may have to use a test piece to experiment with settings and fine-tune them for optimal results. The fabric needs to be positioned on the laser bed, ensuring it is flat and secure. Lastly, while setting up, you must avoid overlapping or wrinkles.

Step 3: Fabric Cutting

You need to run a test cut on a small scrap of your fabric to confirm settings and edge quality. For that, you need to first secure the fabric onto the cutting bed using a vacuum table or other holding mechanism. Then, activate the laser cutter and monitor the process to ensure smooth cutting and no unexpected burning. Make sure there is proper ventilation.

Step 4: Post-processing

After cutting, any residue or charring should be removed from the edges. Depending on the fabric and application, additional finishing, such as washing or ironing, may be needed. By doing so, you can ensure that the fabric laser-cutting machine will last for a long time.
