Large-format marble processing: the laser revolution

Laser processing on marble is increasingly widespread in the interior design sector, as it gives this precious material unique and durable effects over time, allowing decorations never seen before. Refined decorations, exclusive textures, customizations with fine lettering and company logos are some of the applications that laser machines equipped with high power and high resolution and precision have made possible. In two words: efficiency and objective results.

Today, OT-LAS laser technology for marble and natural stone also exceeds the limits of the size of the workable slabs. Thanks to new high-power large format marble laser machines, companies can process large surfaces with extraordinary precision and versatility.

How laser works on marble

Laser processing of marble is a cutting-edge process that uses a highly concentrated infrared beam to cut the surface of the material. Unlike traditional techniques such as sanding or bush hammering, laser allows for very high precision machining without the need for contact with physical tools. This greatly reduces the risk of damaging the material, making the laser particularly suitable for even the most delicate or valuable marbles.

The machining process from design to final result

The laser process begins with the creation of a graphic file, which can include writing, logos, textures, decorative patterns or even photographs. The file is then loaded into the machine’s graphic and operating software that interfaces with the machine’s hardware and provides laser operating instructions. Once the various parameters, including power and speed, have been set, the machine is able to reproduce the file on the marble surface. The high-power CO2 laser beam interacts with the material, subliming it with extreme precision, producing extraordinary effects.

In addition to precision, this technology offers a considerable saving of resources both in terms of time and costs of construction and energy resources. By not requiring physical tools, the laser reduces wear problems and avoids the use of chemical solvents or inks, proving to be an environmentally friendly and sustainable option.

Exclusive decorative effects for interior design and architecture

The laser processing of marble has opened up new creative possibilities to give shape and concreteness to exclusive and original projects. The engravings obtained with this technology enhance the natural beauty of marble, transforming each slab into a design element capable of capturing attention and defining the identity of a space. Three-dimensional textures, ornamental motifs and artistic engravings come to life with extraordinary sharpness and destined to last over time. The results obtained are therefore increasingly appreciated for embellishing interior design projects and architectural works. Possible applications include, for example:

• Custom wall and floor coverings with three-dimensional textures and geometric patterns that give depth and character to the rooms.
• Exclusive furnishing accessories such as tables or worktops with refined engravings.
• Unique and sophisticated artistic decorations, perfect for elegant environments such as luxury residences, hotels or public spaces.
• Engravings on marble for tombstones and commemorative plaques, made with incredibly defined details and able to resist the elements.
• Custom-made designs in different styles, from the most classic to the most contemporary with unique results on both light and dark surfaces, exploiting the natural contrasts of the material.

The advantages of laser processing on marble

Laser machines for marble processing offer many practical and economical advantages over traditional methods such as polishing, beading, acid-etching and sandblasting. The reasons why laser has replaced these machining techniques include:

More precision and detail

Laser processing ensures unprecedented definition. With the right settings, you can reproduce extremely complex graphics and textures down to the smallest detail. You can also vary the power of the laser beam to achieve different effects and shades, replacing the need for inks.

Energy saving and ecological

The laser is a sustainable and environmentally friendly technology: it does not generate significant waste, does not use chemical solvents and consumes much less energy than other techniques. This makes it an ecological and cost-effective choice that accompanies the evolution of companies towards a lower environmental impact.

Versatility of use and infinite customization

With a single laser machine, you can work marble of different types, as well as other natural stones, such as onyx, slate, quartz and many other materials. This eliminates the need for dedicated tools and associated maintenance costs, while also minimising machine setup times. The laser also allows to reproduce countless patterns and patterns on marble simply by loading any graphic file. A much simpler and faster process than, for example, sandblasting, where it is necessary to apply adhesive films to the marble to protect the plate from treatment, realize the desired shape with the cutter and then proceed to the stripping with the risk of ruining the material.

Duration of the result

One of the major advantages of laser engraving is that it does not deteriorate over time and resists weathering. With this technique the workmanship remains unchanged for years, even in external conditions, proving ideal not only for interior design but also for outdoor and architecture.

Safety and ease of operation

The absence of direct contact and the use of a controlled laser beam make the process safer for operators, eliminating the risk of mechanical tool accidents. The guards installed on the machine protect the operator from the laser beam and all the procedure takes place in total safety. Those who work marble with laser are also protected from the risks arising from inhalation of substances harmful to breathing. During the process no waste materials or dust are generated that remain in the air, but only the smoke resulting from the vaporization of the material is promptly aspirated.

Which stones are suitable for laser processing and engraving?

Laser machining lends itself to the customization of a wide range of natural stones, offering excellent results on materials with different characteristics. Among the most suitable stones are:

• Marble: ideal for detailed engravings, thanks to its fine grain and even surface.
• Granite: perfect for engraving, especially on dark surfaces.
• Onyx and basalt: particularly appreciated for sophisticated decorations and elegant textures.
• Slate: a natural stone ideal for creating surfaces with a satin and matured effect
• Precious stones: for example, malachite, lapis lazuli and agate, which can be worked with specific settings to obtain refined engravings.

Even less conventional materials, such as terracotta, can be laser engraved, further extending creative possibilities.
