Ceramic

Laser Engraving CeramicsThere are many types of ceramic so the results can vary. Typically there is some material removal from laser processing ceramic and thus an "engraved' mark is achieved. In some cases not only the top surface is affected, but also the underlying material. This is more common in commercial grade ceramic items such as earthenware.

Industrial ceramics are typically much more heat resistant and have a better quality front surface. Because of the surface condition, engraving is usually of the very highest quality.

In most cases ceramic materials are best processed with powers of 45 watts or more. This also allows for higher production rates due to the extra speed that corresponds to higher power.

There are special tiles that are readily available, that actually create a rich dark contrast, when processed with a CO2 laser. Trotec will be happy to provide vendor information related to these products.

When inscribing ceramics with laser systems, the results will depend greatly on the type of ceramic. Often, slight material wear-off is achieved. Household ceramics such as earthenware can be engraved. Here, the glazing is stripped off and - depending on laser output - also the underlying material. Corresponding effects are achieved when the surface is covered beforehand with masking tape and the engraved surface is covered with color.

Laser Marking Ceramics

Industrial ceramics are generally more heat-resistant and have a much finer surface. Therefore, the engraving appears especially clean. Since the laser engraving of ceramics requires higher laser outputs, laser systems with a higher output (starting from 45 watts) work more productively than devices with a lower output. A special laser application on ceramic is the processing of special tiles (laser tiles). These can be directly inscribed with a CO2 laser engraver, and produce a rich, dark contrast.

The results obtained in marking ceramics with laser systems depend highly on the type of ceramic. Usually slight material removal is achieved. Household ceramics such as stoneware can be engraved. This involves removing the glazing, and – depending on the laser power – some of the underlying material too.

Nice effects can be achieved if the surface is covered beforehand with masking tape and the engraved surface is designed in color. Industrial ceramics are generally heat-resistant and have a smoother surface. The resulting engraving appears especially clean.

Since laser marking of ceramics requires high laser powers, laser systems at higher power levels (starting at 45 Watt) are more productive than devices with lower power outputs. One special laser application on ceramics is processing of special tiles (laser tiles).

They can be marked directly with a CO2 laser, which produces a full, dark contrast.
