Metals are less preferred material in terms of laser engraving and etching due to its high melting temperature. With that being said, it is not entirely impossible to engrave on metal surfaces. In fact, various industries like automotive, medical, jewelry, energy and aeronautics have been using laser engraved parts for their operations. But, the success of your metal engraving project depends on several factors like the type of machine, choice of metal, intricacy of design and laser power. From the necessary equipment to the best practices for getting the job done, we’ll walk you through each step to ensure your project’s success in this article.

Six Steps to Laser Engrave Metal: A Complete Guide

As laser engravers, here are our five tried and tested steps to laser engrave metal for perfect outcome everytime.

1. Pick the Right Engraving Machine

Before engraving any metal, you must choose an appropriate engraving machine as it can either make or break your engraving project. Different types of lasers emit varying light of specific wavelength based on their gain medium. The wavelength emited is extremely important as it affects how energy is absorbed by the metal. Generally, metals react well to fiber lasers because most of them absorb wavelength efficiently. So, it’s a good idea to go with fiber laser when engraving metals. CO2 lasers on the other hand are not an ideal choice for metal engraving project as their wavelength is not absorbed well. ALSO READ: Everything You Need To Know About Laser Engraving

2. Choose the Right Metal

Selecting the appropriate type of metal for laser engraving is essential. Some metals, such as stainless steel and aluminum, are easier to engrave than others, such as brass or bronze, which are more challenging. Here is a list of specialities for common metal materials and alloys: Aluminium: Aluminium can be marked at high speed as it absorbs fiber laser light efficiently. Steel: Steel can not be marked as fast as softer metals. Also white marking on steel can be created faster than black markings. Stainless steel: Stainless steels are ideal for annealing laser process as the chromium oxide layer on the metal surface must usually remain intact to prevent rust. Copper: When working with copper, high speed markings are not possible. It doesnot absorb fiber laser light as efficiently as other metals. Lead: Lead is one of the metals that absorb s fiber laser light most efficiently. It is also easy to mark at high speed.

3. Prepare the Design

The next step is to prepare the design that will be laser engraved on the metal surface. This can be done using computer-aided design (CAD) software or by creating a design manually. It is essential to ensure that the design is of high quality and resolution and that it is properly optimized for laser engraving.

4. Clean the Metal Surface

Before starting the engraving process, it is necessary to clean the metal surface thoroughly. This helps to ensure that the laser beam is not obstructed by any dirt, oil, or residue that could affect the quality of the engraving. A clean metal surface also allows for better adhesion of the laser-engraved markings.

5. Set up the Laser Engraving Machine

The next step is to set up the laser engraving machine. This involves positioning the metal on the machine’s platform, aligning the laser beam, and setting the parameters such as power, speed, and focus. Proper machine set-up is crucial for achieving the desired engraving result and ensuring the safety of the operator.

6. Engrave the Metal

Finally, the metal is ready to be laser engraved. The laser beam is directed onto the metal surface, vaporizing the metal and creating the desired markings. This process is repeated until the entire design is complete. The laser engraving machine is then turned off, and the metal is removed from the machine. The result is a precise, durable, and high-quality laser engraving that is ready for use. ALSO READ: 10 Best Materials Used for Laser Engraving

The Benefits of Laser Engraving and Laser Etching on Metal

Laser engraving and etching on metal can greatly enhance the appearance and premium appeal of metal products. Here are some of the benefits of using these techniques on metal surfaces:

1. Precision

Laser engraving and etching on metal provide high levels of precision and accuracy, allowing manufacturers to create intricate and detailed designs and markings.

2. Durability

The markings produced by laser engraving and etching on metal are permanent and highly resistant to wear and tear, ensuring that your designs and logos remain visible and readable for a long time.

3. Versatility

Laser engraving and etching can be used on a wide range of metals ranging from stainless steel, aluminum, steel, copper lead, and more. Considering the varied requirements and reactions of the metal to the laser beam, you can pick the ideal material for your project.

4. Aesthetics

Laser engraving and etching on metal surfaces add a touch of elegance and sophistication to metal products, making them more visually appealing and attractive to customers. This can help to increase brand recognition and customer loyalty, as well as the perceived value and premium of the product.

5. Cost-effectiveness

Laser engraving on metal can be cost-effective and time-saving compared to traditional manual engraving on metal. It is not only a cost-effective solution but also offers precision and durability without the need for extensive labor. It is fast and efficient allowing mass customization of high volumes of products at a relatively low cost per unit. ALSO READ: How to Choose the Best Wood for Laser Engraving
