Choosing the right type of laser is one of the most important decisions when entering the world of laser cutting and engraving. Hobbyists, creative individuals, and small businesses often face the question: “Diode vs. CO2 laser?” Fiber lasers are also worth considering. In this article, we compare these three laser types in terms of materials, applications, pros and cons, and costs.
Types of Lasers
Diode Lasers
Diode lasers are especially popular among beginners and DIY enthusiasts. They are excellent for small craft projects, such as engraving wood and cutting paper or cardboard. Due to their low power, they are ideal for delicate work and detailed engraving, such as personalized gifts or models. Another advantage is their ease of use and low maintenance requirements, making them an excellent choice for hobbyists.
Materials:
- Engraving: Wood, plastic, leather, paper, coated metal, glass (with coating)
- Cutting: Thin wood, paper, cardboard, foam
Advantages:
- Affordable (starting at around €150)
- Compact and portable
- Energy-efficient with low power consumption
- Easy to maintain
Disadvantages:
- Limited power, suitable only for thin materials
- Cannot cut transparent acrylic
- Slower cutting compared to CO2 lasers
- Cannot cut or engrave metals (only with special coating)
CO2 Lasers
CO2 lasers are mainly used for working with a wide range of materials, especially wood, acrylic, and leather. They are often utilized by small businesses that produce signs, jewelry, or custom decor items. Their versatility also makes them popular in creative workshops as they can both engrave and cut. Another highlight is their ability to process organic materials like glass or stone, making them a preferred choice for artisans.
Materials:
- Engraving: Wood, acrylic, leather, plastic, glass, stone, ceramics
- Cutting: Wood, acrylic, leather, fabrics, paper, cardboard
Advantages:
- Higher power for fast engraving and cutting
- Wide range of materials
- Very precise results
Disadvantages:
- Higher initial cost (starting at around €500 for entry-level models)
- Larger and heavier than diode lasers
- Requires regular maintenance (e.g., cleaning optics)
Fiber Lasers
Fiber lasers are primarily used for metal processing and are designed for industrial applications. They are perfect for engraving metal parts, such as nameplates, tools, or personalized gifts made of stainless steel. Thanks to their speed and precision, they are highly efficient for mass production. Their long lifespan and low maintenance make them attractive for businesses willing to invest in a robust and powerful machine.
Materials:
- Engraving: Metals (stainless steel, aluminum, brass, copper), plastics, coated metals
- Cutting: Very thin metals (depending on power)
Advantages:
- Ideal for metal engraving
- Long-lasting laser source (up to 100,000 hours)
- Very precise and fast
- No maintenance required for the laser source
Disadvantages:
- Very expensive (starting at around €2,000)
- Limited material variety (not suitable for wood or acrylic)
- More complex software for beginners
