¶ 1. Introduction to Laser
Laser (Light Amplification by Stimulated Emission of Radiation) is a type of light emitted through stimulated radiation, characterized by its monochromaticity, strong directionality, high brightness, and good coherence. The principle involves using a specific optical medium (such as gas, liquid, or solid) to amplify light signals, ultimately releasing a strong, concentrated beam of light. Laser technology is widely applied across various fields. Among these applications, laser engraving/cutting equipment utilizes high-energy concentrated lasers to vaporize the material's surface, allowing for the engraving of patterns or cutting materials into desired shapes. The Bambu Lab laser module uses blue laser light at 455 nm ± 5 nm to precisely engrave patterns on surfaces or cut materials to meet diverse needs.
Although lasers have a wide range of applications, their high-energy characteristics also pose certain safety risks. Intense laser beams can cause irreversible damage to the eyes, potentially leading to blindness, especially when they are directly or indirectly exposed to the eyes. Additionally, laser radiation at high power can cause skin burns and, in specific situations, may lead to fires or explosions. Therefore, the correct use of laser equipment is crucial, and safety measures should not be overlooked. In response to the potential hazards of lasers, organizations such as the International Electrotechnical Commission (IEC), the American National Standards Institute (ANSI), and the European Committee for Electrotechnical Standardization (CENELEC) have established strict laser safety standards, mandating that laser equipment of different power levels must be equipped with corresponding safety protection measures.
¶ 2. Laser Classification
Laser Beam Hazards
Laser beams can be hazardous because the energy of the laser can damage the eyes and skin. This can cause damage to both eyes and skin. Red and infrared lasers mainly cause thermal damage to the cornea. Blue light and UV light are more dangerous because they can penetrate the cornea and lens to reach the retina, potentially causing long-term damage like macular degeneration and retinal burns.The risk is higher if the laser is more powerful if it is more focused, and if it stays in one place for a longer time, so all of these factors are considered when assessing safety. Direct laser exposure, specular reflection, and diffuse reflection can result in varying degrees of injury. It is imperative to adhere to the standard operating procedures outlined in the instructions.
Laser GeneratedAir Contaminants
When using a laser to process materials, various potentially harmful air contaminants may be generated. Please follow the user manual to ensure that all exhaust is either filtered through an air purifier or discharged outdoors where it can safely dissipate.
| Classfication | Laser power | Discription | Application | Protective Measurement |

-
**Processing of materials made of mirrors is prohibited, reflected laser light is very dangerous and can damage people and machines.
Tips
When you use a 455 nm laser to process materials with blue surfaces, most of the laser light is reflected by the material and not absorbed. More power is needed to achieve results.
¶ Materials and Hazards
| Material | Hazard |
|---|---|
| PVC (including PVC artificial leather, transparent PVC sheets, etc.) Vinyl (specifically heat transfer, stickers, etc.) |
Cutting releases irritating gases (such as chlorine), which may damage optical components and metals, affecting machine performance. It is recommended to avoid cutting. If necessary, wear a gas mask and use an air purifier. |
| Leather, PU artificial leather | Cutting may release harmful gases and irritating odors. Ensure good ventilation and use an exhaust system. Leather and PU materials are flammable; keep away from flammable items and maintain a clean work area. |
| ABS | Gas Release: Cutting ABS releases cyanide gas, which is toxic. Always operate in a well-ventilated area and use an exhaust system to remove fumes and gases. Melting Properties: ABS tends to melt rather than vaporize when laser cut, leading to uneven edges. Adjust laser power and cutting speed to minimize melting and burning. Protective Equipment: Wear appropriate protective masks and goggles to prevent inhalation of harmful gases. |
| PLA | Gas Release: Cutting may release a small amount of harmful gases. Generally safe but requires good ventilation. Melting Properties: Easily melts; adjust laser power and speed to prevent burning and sticking. |
| PETG | Smoke and Odor: Cutting may release irritating odors; use an exhaust system to maintain ventilation. Melting and Adhesion: PETG melts easily, requiring controlled cutting parameters to prevent sticking to the laser head. |
| TPU | Harmful Gases: Cutting may release harmful gases; always operate in a well-ventilated environment. Cutting Difficulty: Due to its flexibility, TPU may melt and deform during cutting. Adjust speed and power carefully. |
| ASA | Harmful Gases: Cutting may release irritating and harmful gases; wear a protective mask and ensure good ventilation. Material Properties: More heat-resistant than ABS; laser parameters must be controlled to avoid deformation. |
| HDPE | Melts easily and catches fire. |
| Polystyrene Foam | Melts easily and catches fire. |
| Polypropylene Foam | Melts easily and catches fire. |
| PC (Polycarbonate), Latex Paint | Discoloration and combustion. |
| Coated Carbon Fiber | Produces harmful gases. |
| Acrylic | Produces harmful gases. When processing such materials, it is recommended to wear a gas mask or use an air purifier. Acrylic has good light transmission at the 450nm wavelength. Blue laser sources (450nm) may penetrate rather than cut opaque acrylic. Select suitable materials accordingly. |
| Rubber | Cutting may release toxic smoke and gases with irritating odors. Use an exhaust system with air filtration to prevent inhalation. |
| Synthetic Fibers (Polyester, Spandex, Nylon, etc.) | Releases smoke and fine particles, potentially containing harmful substances hazardous to humans and the environment. Ensure effective exhaust or air purification systems and good ventilation. These materials tend to melt rather than vaporize under high temperatures, leading to hardened or uneven edges. Adjust laser power and speed to minimize this issue, using low power and high-speed cutting when possible. |
¶ Safe materials
Materials that can be cut by a laser include wood, paper, cork and some types of plastic, and can be engraved on most objects such as: wood, paper, coated metals, stainless steel, plastics, marble, stone, tiles, glass and more.
- Laser cutting
| Material | Precautions | Warnings |
|---|---|---|
| Most Woods | Avoid oily and resinous woods. | Be extremely cautious when cutting oily or high-resin content woods, as they are highly flammable. Be wary of cutting wood at 100% power with a speed lower than 2%. |
| Bamboo | Cutting may leave burn marks; post-processing such as sanding or coating is recommended to improve the quality of the final product. | Bamboo is a flammable material; keep the work area clean, away from flammable objects, and have a fire extinguisher ready. |
| Plywood, Composite Wood | Contains glue and may not cut as well as solid wood. | |
| MDF, Engineered Wood | Can be cut, but may produce a lot of burn marks. | |
| Paper, Cardstock, Kraft Paper | Cuts very well and very quickly. | Cutting paper produces smoke; ensure proper ventilation and use an exhaust system to remove the fumes. |
