The CO2 laser is one of the most widespread technologies for engraving natural materials, such as stone, wood and fabric, with results of remarkable elegance and functionality. The performance in terms of precision, customization and sustainability make CO2 laser systems indispensable for a wide range of applications. From interior design to fashion, from architecture to furniture, to name just a few, there are many sectors that have adopted this technology. Let’s find out how the CO2 laser works, which natural materials it can work with and what are the advantages over traditional methods.
What is the CO2 laser for engraving natural materials
The CO2 laser for engraving natural materials is an advanced technology that combines precision, speed and sustainability. Thanks to the power of the laser beam and the galvanometric scanning head for the movement and focusing of the beam, it is possible to obtain engravings on wood, fabrics and natural stones of the highest quality, also ideal for interior design and furniture. The laser’s efficiency and accuracy increase productivity, reducing operating costs and environmental impact while respecting the natural beauty of the material.
What is the difference between laser engraving and laser marking?
Although the two terms are often used as synonyms, engraving and laser marking indicate two distinct processes:
- CO2 laser engraving: removes the material from the surface, creating a visible and permanent groove. It is ideal for drawings, decorations, patterns and writings with three-dimensional effect.
- CO2 laser marking: changes the material only on the surface, often creating a color contrast (blackening or discoloration) due to the thermal effect. It is perfect for identification codes, serial numbers, logos or graphics that do not require a deeper engraving.
Both processes are contactless, that is without contact of a mechanical tool with the object. This feature significantly reduces the risk of deformation of natural materials and saves on system wear.
Which natural materials can be processed with the CO2 laser?
One of the strengths of the CO2 laser is its outstanding compatibility with a wide range of natural materials used that require particular care and accuracy. This advantage makes the laser a perfect technology for interior design companies. The main organic materials processed by laser include:
Micro-drilling and engraving of wood
Wood is a natural material that has always been appreciated in interior design for its versatility and performance. The range of textures, shades and veins, the warm and timeless aesthetic, the insulating properties, both thermal and acoustic, make it a valuable ally. For these reasons wood is widely used to make furniture, floors, vertical cladding and decorative elements.
In recent years, the choice to use laser for engraving wood has revolutionized the sector with a level of customization and functionality previously unattainable. The CO2 laser is suitable for engraving different types of wood, such as solid wood, plywood, chipboard, teak, cherry, maple, oak, bamboo, beech, cork, not to mention veneers and multilayer wood. In addition, the CO2 laser allows to obtain unique textures and engravings on wood refined and complex in full respect of the material.
In addition to the engraving, the micro-drilling of wood with special laser machines makes it possible to obtain sound-absorbing acoustic panels of exceptional efficiency. Systems such as CX Microperforation and PX allow to obtain also aesthetically valuable sound absorbing textures and patterns, thanks to the extraordinary precision of the microholes and their distribution, easily modifiable via software.
Laser for tissue processing
Natural fabrics have also rediscovered a leading role in interior design. Often produced with sustainable methods, fabrics such as cotton, linen and hemp bring freshness and harmony to the environment, improving the quality of the environment. In addition, the natural elegance of these materials makes it possible to make coatings, upholstery, curtains and pillows of particular beauty.
The use of laser for fabric processing has introduced a turning point in terms of productivity, sustainability and customization. The laser can process a wide range of natural fabrics such as silk, jute, cotton and linen, in addition to synthetic fabrics. The laser cutting systems for fabric allow to cut the material with extreme precision leaving the edges perfectly sealed.
Thanks to the CO2 laser you can achieve very special effects, such as graphics, discoloration, worn effect and unique patterns with extraordinary speed and, above all, without polluting. In fact, laser technology does not require the use of inks or sanding or polluting or toxic processes, protecting the environment and the health of operators. Advanced laser technology such as OT-LAS’s CX XL also offers additional advantages such as cutting and engraving directly from the roll and combining processing in a single operation.
Laser marking and engraving for leather and fabric
Among the fabrics of natural origin, leather has always been particularly successful in design upholstery. Precious and resistant, the leather gives a touch of exclusive class to both classic and modern environments, giving uniqueness and value to armchairs, sofas, beds and seats. Thanks to the laser it is possible to work different types of skin reducing the risk of damaging the material, although durable, must be treated gently. Natural leather, nubuck, suede can be worked with refinement and precision to create cozy and sophisticated furnishings and coverings.
Laser engraving for marble and stone
Marble and natural stone are materials capable of enhancing any environment with scenic effects and inimitable textures. The timeless class of marble, with its precious veins and the wide range of possible finishes find space in interior design in different forms and types of furniture and coating. At the same time, natural stone stands out for its durability and performance, with insulating properties and smooth or rough surfaces that create sophisticated play of light and shadow.
CO2 laser systems can cut marble and other natural stones, such as granite, onyx, quartz, pebbles, malachite, lapis lazuli, agate, slate and travertine, with surprising versatility. From the processing to obtain brushed surfaces, smoothed or flame effects or embossing to engravings of fine writing and decoration, the laser opens stylistic horizons of exceptional creativity. In addition, the precision of the laser beam and contactless processing allow to minimize material waste, also reducing the impact on the environment.
Some laser machines offer specific advantages for machining on certain materials, such as OT-LAS machines for machining on wood, fabric or marble.
