Ambas máquinas pueden grabar o marcar una amplia gama de materiales., sin embargo, grabador láser de fibra are designed to work with metal, leather and plastic whereas CO2 lasers are compatible with a wider range of materials (Not ideal for plastics).
En esta guía completa, we’ll delve deep into the distinctions between these two technologies, focusing on their uses, benefits, and the specific capabilities of the CommMarker fiber laser engraver.
Understanding Laser Engraving Technology
Laser engraving is a versatile process used to etch designs, texto, or images onto various materials. The technology employs a focused laser beam to remove material, creating precise and intricate patterns. The two main types of laser engravers are CO2 and fiber lasers, each utilizing different methods to generate and manipulate the laser beam.
CO2 Laser Engravers
How They Work
CO2 laser engravers use a gas mixture primarily composed of carbon dioxide, which is excited by electrical energy to produce a high-intensity laser beam. This beam is then directed through a series of mirrors and a focusing lens to the material surface. The wavelength of CO2 lasers is around 10,600 nanómetros, which is effective for cutting and engraving a wide range of non-metal materials.
Applications and Materials
CO2 lasers are highly versatile and can work with various materials, incluido:
Madera: CO2 lasers can engrave and cut wood with great precision, making them ideal for woodworking projects, regalos personalizados, y señalización.
Acrílico: Clear and colored acrylics can be engraved and cut with smooth edges, perfect for display cases, awards, and artistic designs.
Cuero: Both natural and synthetic leathers can be engraved for fashion accessories, custom patches, and detailed artwork.
Vaso: While direct engraving on glass can be challenging, CO2 lasers can etch patterns with a frosting effect, often used for decorative items and glassware.
Paper and Cardstock: Ideal for creating intricate patterns for invitations, greeting cards, and paper art.
Goma: Used for making custom stamps and gaskets.
Tela: CO2 lasers can cut and engrave various textiles for fashion, upholstery, and craft projects.
Ventajas
Versatilidad: CO2 lasers can engrave and cut a wide range of non-metal materials, making them suitable for diverse applications.
Affordability: Generally more cost-effective than fiber lasers, CO2 engravers are accessible to small businesses, aficionados, and educational institutions.
Larger Workbed Options: CO2 lasers often come with larger workbed sizes, allowing for the processing of bigger pieces of material.
Desventajas
Mantenimiento: Requires regular maintenance, including mirror alignment, bed leveling, and cooling system upkeep.
Setup Complexity: Involves a more complex setup process, including venting exhaust and aligning optical components.
Limited Metal Engraving: While CO2 lasers can mark coated metals, they are ineffective for engraving bare metals without special marking agents.
Grabadores láser de fibra
How They Work
Grabadores láser de fibra, like the CommMarker, generate laser beams through a fiber optic cable doped with rare elements such as ytterbium. This method produces a laser beam with a wavelength of approximately 1,064 nanómetros, which is highly absorbed by metals and other hard materials. The beam is directed through a galvanometric system (galvo) with fast-moving mirrors that accurately position the laser on the material surface.
Applications and Materials
Fiber lasers are particularly effective for metal engraving but can also work with other hard materials. Common applications include:
Rieles: Fiber lasers can engrave a wide range of metals, incluyendo aluminio, latón, acero inoxidable, oro, plata, titanio, y más.
Hard Plastics: Certain hard plastics can be engraved with fiber lasers, often used for industrial components and identification tags.
Piedra: Materials like granite, mármol, and brick can be engraved for memorials, architectural details, and decorative items.
Joyas: Precision engraving on rings, esposas, and other jewelry pieces.
Ventajas
Alta precisión: Láseres de fibra, such as the CommMarker, offer unparalleled precision and detail, making them ideal for intricate designs and small text.
Low Maintenance: Fiber lasers require minimal maintenance compared to CO2 lasers, with no need for mirror alignment or cooling systems.
Velocidad: The galvo system in fiber lasers allows for rapid engraving speeds, increasing productivity.
Durabilidad: Fiber lasers have a longer operational lifespan and higher energy efficiency.
Metal Compatibility: Capable of engraving various metals without the need for additional marking agents.
Desventajas
Costo: Generally more expensive than CO2 lasers, making the initial investment higher.
Material Limitations: Less versatile in terms of the variety of materials they can process, primarily focusing on metals and hard plastics.
Smaller Workbeds: Typically come with smaller workbed sizes, which can limit the size of the pieces you can work on.
