Enhancing Laser Engraving Depth

Have you ever examined coins or metal plates closely and noticed the distinctive markings or raised logos on them? These features showcase the art of deep surface engraving, a technique that carves into the material, creating noticeable depth and leaving a lasting mark. Unlike standard laser engraving, deep engraving ensures a more prominent and tactile impression on the surface, making it stand out visually and by touch. This method finds applications in various industries, adding a unique touch to products and personalizing items with a deeper level of customization.

In our exploration of deep engraving, it becomes evident that this technique goes beyond mere aesthetics. Its significance lies in the versatility it offers across different materials and the ability to create lasting, tactile impressions. From enhancing product branding to adding sentimental value through personalized items, deep engraving emerges as a powerful tool for elevating the visual and tactile appeal of various objects.

How can one achieve deep laser engraving? 

Deep laser engraving utilizes a high-powered laser beam to vaporize material, removing surface layers and creating a distinctive design with recessed areas. This outcome resembles the raised patterns seen on stamps or coins. The design appears elevated due to the surrounding surface being etched away. This precise and controlled process results in intricate and durable engravings, suitable for a variety of applications, including industrial marking and artistic creations. The powerful laser ensures efficient material removal, contributing to the creation of detailed and visually striking designs that make an impact in both functionality and aesthetics.

In conventional engraving, the laser beam eliminates material, creating a lasting mark beneath the surface. Conversely, deep engraving elevates the design by extensively removing the surrounding surface. This method demands greater power, depth, and time compared to standard engraving. The distinctiveness of deep engraving lies in its ability to generate standout designs with pronounced features. The process involves a more intensive removal of material, resulting in a visual depth that sets it apart from traditional engraving. While standard engraving embeds the mark within the material, deep engraving transforms the surface itself, making the design more prominent and tactile. The additional power and precision required make deep engraving a specialized technique suited for applications where a bold and dimensional visual impact is desired.

Expanding upon deep engraving, there is a technique known as 3D laser engraving. In this method, the degree of material removal varies, resulting in a design with a three-dimensional aspect. While 3D engraving shares similarities with deep engraving in terms of technique, it introduces an additional dimension to the design, thereby amplifying the visual impact.

What is the maximum depth achievable with laser engraving? 

Deep laser engraving is distinguished by its capacity to surpass the depth achieved in standard engraving methods. In conventional cases, standard engraving achieves depths of approximately 500 microns or 0.5mm. However, no universal standard dictates this depth. The exceptional feature of deep engraving lies in its variability, influenced by the capabilities of the engraving machine and the specific demands of the design. Generally limited to a few millimeters, the depth achieved in deep engraving not only enhances aesthetic appeal but also imparts a raised and visually striking quality to the design.

Can You Deep Laser Engrave Metal? 

Deep laser engraving proves highly effective on metals, and it's a prevalent technique in various applications. Achieving optimal results, however, necessitates precise adjustment of engraving parameters. Precious metals like gold, silver, and platinum stand out as excellent candidates for deep engraving, particularly in the jewelry industry where intricate designs are in demand. Stainless steel, another metal amenable to deep engraving, introduces a caveat—deep engraving may compromise its oxide layer, raising the risk of corrosion. This concern extends to iron as well, prompting the need for protective measures such as chrome plating or post-engraving painting to mitigate potential issues.

In deep laser engraving, the choice of laser technology plays a pivotal role. Pulsed fiber lasers, renowned for their potency, are commonly employed in industries for deep engraving metallic parts due to their efficient material removal. While other laser types can be used, their operation tends to be slower, making pulsed fiber lasers the preferred choice for applications where speed and precision are paramount. In essence, deep laser engraving on metals is a nuanced process that demands a careful balance between power, material considerations, and protective measures to yield durable and visually appealing results.

Uses of Deep Laser Engraving 

Deep laser engraving is employed across various applications where enduring markings are essential. Its usage spans:

1. Industrial Marking:
This technique is frequently applied to engrave logos, lettering, and serial numbers onto machine parts. By utilizing deep laser engraving, these crucial identifiers gain longevity and resilience against wear and tear..

4. Coin Engraving:
Coins frequently showcase detailed designs and text, and deep laser engraving is instrumental in achieving this level of intricacy. This technique enables the creation of precise and detailed patterns, essential for enhancing the aesthetic appeal and authenticity of coins. Deep engraving ensures that the fine details on coins are accurately reproduced, contributing to their overall visual appeal and value.

How Do You Make Laser Engraving Deeper? 

To achieve deeper laser engraving, we need to fine-tune multiple machine parameters like speed, optical power, and number of passes.

Optical Power

The predominant factor influencing deep laser engraving is power, with higher optical power facilitating deeper engraving in a shorter duration. To achieve deep laser engraving on metal, a minimum of a 100W fiber laser is typically required, contingent upon the metal's hardness. Different materials may necessitate varying power levels; while some may require less power, an adequate power level is crucial for effective engraving. In cases where the laser is underpowered, the desired depth can still be attained, albeit at a slower pace. Hence, the optimal power setting is pivotal in balancing efficiency and speed in the deep laser engraving process.

Speed

The velocity of the laser head's movement over the material is a critical factor. Opting for a lower speed grants the laser more time on each area, resulting in deeper cuts during the engraving process. However, it's essential to exercise caution and strike a balance, particularly with materials such as wood, as setting the speed too low can risk burning or excessive removal of material. Achieving an optimal speed setting is key to ensuring the efficiency and precision of the laser engraving process while avoiding potential issues associated with prolonged exposure or over-removal of material.

No. of Passes

When using a less powerful laser machine but seeking increased depth, one strategy is to augment the number of passes made by the laser head. This method allows for the attainment of greater depth through multiple repetitions over the same area. However, it's important to note that this approach is inherently more time-consuming due to the necessity of executing numerous passes to achieve the desired engraving depth. While it provides a viable alternative for achieving depth with lower laser power, the trade-off lies in the extended time required for the incremental passes over the material.

Proper Ventilation

Deep engraving necessitates extended processing times and the removal of substantial material, resulting in an extended generation of fumes. Furthermore, both the laser apparatus and the material itself may experience increased heat during this process.

To uphold a safe and cool working environment, it is imperative to deploy an efficient exhaust system equipped with a smoke extractor. This system plays a pivotal role in eliminating fumes, thereby aiding in the regulation of temperature throughout the engraving process. Implementing such measures not only ensures a comfortable and secure workspace but also contributes to the overall efficiency and effectiveness of the deep engraving procedure.

What Deep Laser Engraving Machine Do You Need?

When it comes to industrial deep engraving, fiber laser machines are the recommended choice due to their efficiency and power. However, for small businesses or for personalizing items at home with deep engraving, an excellent option is the powerful diode laser machine, such as the xTool S1.
