Die Lasergravur ist ein Fortschritt, effiziente Methode zum Markieren und Ätzen auf verschiedenen Materialien, einschließlich Metalle. Ob Sie ein Bastler sind, a small business owner, or a professional engraver, finding the right equipment for metal marking without breaking the bank can be a challenge. Jedoch, as the technology has evolved, there are now several cost-effective laser engravers on the market capable of delivering high-quality results for metal engraving.
In diesem Artikel, we will explore what constitutes a “cheap” laser engraver, the various types of lasers used for metal marking, and which laser engravers provide the best value for money for engraving metal. We will also discuss essential factors to consider when buying an engraver for metal marking, the pros and cons of different models, and how to choose the one that suits your needs.
1. Was ist Lasergravur??
Laser engraving is a non-contact process that uses focused laser beams to remove or alter the surface of a material. It works by directing a concentrated light (Laser) onto a material’s surface, where it burns, melts, or vaporizes the material, creating a permanent mark or engraving.
So funktioniert die Lasergravur:
- Laser Beam Focus: The laser beam is highly focused, ensuring precision when it comes to cutting or marking. It can burn through thin layers of the material, leaving permanent marks that are often very detailed.
- Marking Process: Abhängig vom Material, the laser can create different types of effects, including blackening (für Metalle wie Edelstahl), Gravur, oder schneiden.
For metal marking, laser engraving is commonly used to add logos, Text, Barcodes, QR-Codes, Seriennummer, and decorative designs to products.
2. Types of Laser Engravers for Metal
Before we dive into the specifics of “cheap” laser engravers for metal marking, it’s essential to understand the types of lasers typically used for engraving metal.
CO2-Laser
- Wellenlänge: 10.6 Mikrometer
- Am besten für: Primarily used for non-metal materials like wood, Acryl, Glas, und Leder. CO2 lasers can mark some metals, but their performance is not as good on metals as fiber lasers.
- Einschränkungen: CO2 lasers require additional processing (such as applying a coating or chemical solution) Zu engrave metals effectively. Their engraving speed on metals is slower than fiber lasers, and they are not suitable for deep metal engraving.
Faserlaser
- Wellenlänge: 1.06 Mikrometer
- Am besten für: Fiber lasers are specifically designed for marking metals and perform excellently on both ferrous and non-ferrous metals, wie zum Beispiel Edelstahl, Aluminium, Messing, Titan, and even gold.
- Vorteile: Fiber lasers are the preferred choice for metal marking because they provide high precision, tiefe Gravur, and minimal heat affected zone (HAZ). They are also faster and more efficient for metal compared to CO2 lasers.
- Kosten: Fiber lasers tend to be more expensive than CO2 lasers, but many affordable models are available for small businesses or hobbyists.
Diodenlaser
- Wellenlänge: 450-980 Nanometer
- Am besten für: While not as powerful or versatile as CO2 and fiber lasers, diode lasers are often used for low-power engraving applications on metals and other materials.
- Einschränkungen: Diode lasers generally cannot engrave metals with the depth or clarity that fiber lasers can, and they are typically more suited for marking or light engraving rather than heavy-duty applications.
MOPA Lasers
- Wellenlänge: 1.06 Mikrometer (with adjustable pulse width)
- Am besten für: MOPA (Master-Oszillator-Leistungsverstärker) lasers are a variation of fiber lasers that offer even more flexibility. MOPA lasers can provide a wider range of pulse widths, enabling better control over the engraving depth and speed.
- Vorteile: MOPA lasers can engrave metals with superior contrast and more precise results compared to standard fiber lasers. They are ideal for delicate designs and applications that require a high degree of customization.
3. Key Features to Consider for Cheap Laser Engravers for Metal Marking
1. Power and Wattage
- Leistungsbereich: For metal marking, power is a crucial consideration. Low-wattage lasers (10W-20W) can mark metals but won’t produce deep engravings. Medium-wattage lasers (20W-30W) are better for general metal marking, while higher-power lasers (50W+) are suited for cutting or deeper engraving.
- Best Wattage for Metal Marking: Allgemein, 20W to 30W fiber lasers are sufficient for most metal engraving tasks, providing a balance between speed, Tiefe, and affordability.
2. Lasertyp
- Fiber Lasers for Metal: Fiber lasers are optimal for engraving metal surfaces. They are more efficient than CO2 lasers for metal marking, providing higher power, Präzision, and faster engraving speeds.
- MOPA Lasers: MOPA-Laser, a more advanced type of fiber laser, allow for fine control over pulse width and frequency, producing better results on certain metals, particularly when varying depth or contrast is required.
3. Speed and Precision
- Gravurgeschwindigkeit: A good laser engraver should be fast and precise. Speed is important if you’re working on high-volume orders or production lines. A laser engraver with a higher engraving speed (measured in mm/s) will save time, but ensure it doesn’t sacrifice precision.
- Präzision: Precision is measured by the minimum engraving detail (usually in millimeters). For high-quality metal engraving, the engraver should have at least 0.01mm precision.
4. Materialkompatibilität
- A good laser engraver should be able to handle various metals such as stainless steel, Aluminium, Messing, und Kupfer. It should also support a range of materials like plastic, Holz, and glass if you plan on diversifying your product offerings.
5. Kühlsystem
- Air or Water Cooling: High-power laser engravers require cooling systems to prevent overheating. Basic models often use air cooling, which is cheaper and easier to maintain, while higher-end models use water cooling systems for greater performance and longevity.
6. Softwarekompatibilität
- EasyCAD or LightBurn: Many fiber lasers are compatible with design software like EasyCAD (commonly used for fiber lasers) and LightBurn, which is popular for more advanced control over engraving settings and design work.
7. Build Quality and Durability
- The build quality of the laser engraver plays a major role in its performance and longevity. Choose an engraver that is built to last, especially if you plan on using it regularly.
8. Price and Warranty
- Affordable Models: It’s important to balance quality and affordability. While you can find inexpensive models, don’t compromise too much on quality. Consider warranties and after-sales service when choosing a machine.
