When we aim to expand our customization business, we often wonder which laser machine to choose. Sometimes, we're looking for a “small but powerful” model and aren’t sure where to start. Today, we’ll explore how laser machines work and some essential requirements to consider to ensure we make the most of our investment.
The first thing to know is the type of technology in your machine. Laser technology mainly includes Fiber Lasers and CO2 Lasers. The key difference lies in their capabilities and operating methods.
Fiber Laser: This technology generates its own laser using internal energy. It's commonly used for basic engravings on wood, cardboard, plastic, and more. Depending on the power, fiber lasers can handle larger volumes, but the more affordable models you see on eBay are typically for simple markings.
CO2 Laser: In this case, the laser beam is generated through a combination of gases, making it ideal for large-format engraving.
The next essential factor is power. For example, a CO2 laser usually ranges from 40 to 400 watts, while a Fiber Laser typically goes from 10 to 20 watts. This power level determines what you can cut or engrave.
Here are some common material settings for customization:
-
MDF
- Cutting: 50-60 watts
- Engraving: 20-50 watts
-
Acrylic
- Cutting: 30-40 watts
- Engraving: 35-40 watts
-
Paper
- Cutting: 10-20 watts
- Engraving: 15-20 watts
-
Cardstock
- Cutting: 20-30 watts
- Engraving: 30-40 watts
In summary, if you’re looking for an affordable engraving laser, opt for a Fiber Laser with a power range between 10-30 watts. For larger projects, choose a CO2 Laser with 40-100 watts. Besides the technology, remember to check your machine’s cooling requirements and prepare your workspace to prevent potential health risks.
