Part 1: What is Copper Laser Engraving and the Machine?
1.1 Copper Laser Engraving Vs Brass Laser Engraving
Copper is a pure metal with a reddish-orange hue and excellent electrical conductivity, while brass is an alloy of copper and zinc, prized for its corrosion resistance and range in color from yellow to reddish-brown. Despite these differences, both brass laser engraving and copper laser engraving share some similarities.
1.2 How Does Laser Engraving Work on Copper?
Copper laser engraving works by directing a focused laser beam onto the surface of copper, which causes localized heating and vaporization of the material. This process removes a thin layer of copper and creates the desired engraving.
Copper laser engraving is always the better choice among all methods of copper engraving as it offers convenient, precise and durable engraving on various types of copper, providing intricate designs with lasting quality.
1.3 Copper Laser Engraving Machine:
To begin copper laser engraving, you'll require a laser engraving machine. These machines are indispensable for copper engraving process, as they can handle the hardness and density of copper materials, streamlining the engraving process and ensuring precise and durable results.
With numerous laser engraving machines available, some people may wonder What laser is best for engraving copper or What is the best laser engraver for copper?
Compared to CO2 and fiber laser, some people may be concerned about the ability of diode lasers to engrave copper. However, rest assured that you can indeed etch copper with a diode laser.
In fact, diode lasers are well suited for home and small-scale copper laser engraving. So if you are looking for portability, convenience and cost efficiency, a diode laser engravers is the preferable option.

Can copper be lasered? Definitely yes! Whether you prefer patterns, quotes, or images, the process is straightforward. So, How do you engrave on copper? Don't worry, just follow these 5 simple steps to add personalized and intricate designs to your personalized laser engraved copper crafts.
Step 1: Choose Your Copper Material
Selecting the right copper material for laser engraving is crucial for achieving desired results. Copper materials with clear and smooth surface are all good choices. However, please remember that it's important to choose laser-safe copper material to avoid any potential safety hazards.
In this guide, we'll conduct a case study on laser engraving with a copper coffee pot!
Step 2: Choose the Right Laser Engraving Machine for Copper
Here, we choose LaserPecker 4 (LP4), which is a dual-laser and multi-functional laser engraver.
Main Features of LaserPecker 4
- Enhanced Material Compatibility: LP4 is compatible with a wide range of materials, including brass, silicone, rubber, crystal, stone, metal, wood, plastic, leather, and more. It's also capable of cutting paper, wood, acrylic, leather, and fabric.
- Improved Resolution: With selectable resolutions ranging from 1k to 8k, the LP4 provides increased flexibility, allowing users to choose the level of detail that best suits their needs.
- High Engraving Accuracy & Speed: The LP4 exhibits high engraving accuracy and speed, achieving precision levels up to 0.003 mm and speeds reaching up to 4000 mm/s.
Step 3: Prepare Your Engraving Design
Use a free graphic design app/software to create or import the image or pattern you want to engrave on the copper surface. Consider size, shape, and details like text or patterns.
Step 4: Set up the Copper Laser Engraving Machine
Firstly, Make sure your engraver is powered on, and then connect your laser engraver to your computer or mobile device using the appropriate interface (USB cable, Bluetooth, etc.)
Secondly, Open the graphic design software and load your design.
Thirdly, Turn on the "Preview Mode" to confirm if the laser lens is correctly focused. To verify it, you have 2 methods.
If you choose LaserPecker 4 (LP4), the first method is to use a ruler to measure the distance between the copper surface and the machine, with a recommended distance of 15cm or 150mm.
Alternatively, you can achieve the correct focal length by judging whether the two red dots emitted by the machine overlap. This ensures precise focusing for optimal engraving results.
Fourthly, You need to place the items within the designated working area and examine the design's appearance on the copper material. If it doesn't fit correctly, you'll need to adjust its position and size to ensure it aligns with the dimensions of your project.
Finally, Access the software's laser settings to adjust parameters like power, speed, and resolution according to the copper's properties and design intricacy. You might be wondering, "How much laser power is needed to engrave copper material?" and "How deep is the laser etch on copper material?" Rest assured, I've got you covered!
To get the best result, the recommended laserpecker 4 material settings for copper is 10 W 450 nm; Resolution: 1k; Power: 100%; Depth: 40%; Pass: 1
To explore other laserpecker material settings, refer to the settings table that applies to any laserpecker engraving and cutting machines, including LP1, LP2, LP3, LP4 and LX1.
Step 5: Start Your Copper Laser Engraving Now
Double-check everything to avoid mistakes. Then, hit the start button and watch the magic happen. The laser brings your design to life. Keep an eye on it, and you're all set!
When operating a laser engraving machine with a 450 nm blue laser, it's advisable to wear goggles or use a laser protection cover to protect your eyes and body from potential harm, as the blue laser can pose risks.
Additionally, please be mindful that smoke or toxic gases may be emitted during the copper laser engraving process. Wearing a mask or employing an air purifier is essential for safety.
