Can You Laser Cut Leather?
The answer is yes. Leather can be cut with a laser cutter because it absorbs the heat and energy from the laser beam, which vaporizes the material along the cutting line. The result is a clean and precise cut when processed properly.
However, not all types of leather can be laser cut. Some of them are not suitable for laser cutting due to the toxic fumes emitted during laser cutting. Let’s take a look at the main types of leather that can be laser cut.
What Types of Leather Can Be Laser Cut?
As we mentioned before, not all types of leather can be laser cut. Some of them may produce toxic fumes when exposed to the laser beam. There are two main categories of leather that can be laser cut: natural leather and synthetic leather.
Natural Leather
Natural leather, as the name implies, is derived from the hide of an animal, primarily cows, but also from sheep, goats, and other animals. All natural leather can be laser cut, and it generally results in high-quality, professional-looking outcomes.
Synthetic / Faux / Artificial Leather
Synthetic, faux, or artificial leathers are man-made materials designed to imitate the appearance and feel of natural leather. These types of leather are usually made from a plastic base, such as PVC (polyvinyl chloride) or PU (polyurethane), and then treated to resemble leather.
Synthetic or faux leathers can also be laser cut. However, it's important to note that some synthetic leathers, particularly those containing PVC or vinyl, can release harmful chlorine gas when laser cut, which is hazardous to both the user and the laser machine itself.
Therefore, always ensure you know the composition of your synthetic leather before you begin laser cutting, and if it contains PVC or vinyl, consider opting for another material or cutting option, such as blade cutting.
Advantages of Laser Cutting Leather
Laser cutting has many advantages over other methods of cutting leather, such as scissors, knives, or punches. Here are some of the main benefits of laser cutting leather:
Enhanced Precision and Quality
Laser cutting leather allows you to create intricate and complex shapes and designs with high accuracy and detail. This is because laser cutters are controlled using computer software, allowing the user to design their cuts digitally.
Besides, the laser beam is very thin and focused, and can follow any path or curve that you set on the computer software. This method enables the creation of precise, complex, and repeatable patterns that would be nearly impossible to execute by hand.
Moreover, laser cutting leather is a non-contact process, meaning that no physical contact takes place between the cutting tool and the material. This ensures that the leather remains undamaged during the process, as it is not in direct contact with any sharp surfaces.
Faster Efficiency and Cost Savings
Using a laser cutter eliminates the need for manual cutting and reduces the risk of human error. With a laser cutter, you can quickly and accurately cut leather in a fraction of the time it would take with traditional methods. This increased efficiency can help you save both time and money.
Versatility
With a laser cutter, you can cut and engrave various materials including leather, such as wood, acrylic, and paper, making it a highly versatile tool.
Whether you're creating detailed cut-outs, embossing patterns, or engraving fine details, a laser cutter can handle it all. This capability opens up a broad range of possibilities in terms of design and customization.
What Kind of Laser Cutter is Needed to Cut Leather?
For cutting leather, CO2 laser cutters are generally the most suitable due to their wavelength and power.
A CO2 laser cutter operates by electrically stimulating a gas mixture predominantly containing carbon dioxide (CO2), which generates a laser beam.
CO2 lasers are highly effective at cutting and engraving organic materials like leather because of the specific wavelength of light they produce (around 10.6 micrometers). This wavelength is readily absorbed by organic materials, allowing for efficient and precise cutting and engraving.
Can a Diode Laser Cutter Cut Leather?
Diode laser cutters are another type of laser cutter that are often used in the hobbyist market due to their lower cost compared to CO2 lasers. Diode lasers can indeed be used to cut leather, but diode lasers are typically less powerful than CO2 lasers. Diode lasers typically range from 5 to 20 watts. This lower power means that cutting through thicker leather can take longer, and the results may not be as clean as with a CO2 laser.

Tips on Preventing Burn Marks When Laser Cutting Leather
When it comes to laser cutting leather, it is important to take the necessary precautions to ensure that you do not leave any unwanted burn marks on the leather. The laser cutting process requires precise settings to achieve a clean cut without any blemishes, and the wrong settings can result in a botched job.
To help you prevent burn marks when laser cutting leather, here are a few tips to consider.
1. Adjust Power Settings
When using a laser cutter to cut leather, it is important to adjust the power settings accordingly. It ensures that the heat is not too high, which can cause it to burn. If you need help with the correct power setting, consult the instruction manual of your laser cutting machine, as it will provide the most accurate settings for the best results.
2. Adjust Speed Settings
The speed setting also takes an important role in laser cutting leather without burning.
Firstly, you need to consider the thickness of the leather. Thicker leather requires a higher speed setting than thinner leather. This is because thicker leather takes longer to cut and requires more energy from the laser. If the speed is set too low, the laser won’t be able to penetrate the material enough to achieve an accurate cut.
Secondly, different machines have different power levels, so it’s important to adjust the speed settings accordingly. If you’re using a lower power machine, you’ll need to use a lower speed setting to ensure a clean, precise cut. On the other hand, if you’re using a higher power machine, you can use a higher speed setting without risking burn marks.
3. Use Appropriate Laser Focal Length
The laser focal length of your laser cutting machine is crucial when cutting leather. It determines the distance between the laser head and the leather and can affect the cutting precision.
If the focal length is longer, the laser head will be too far from the leather, resulting in a low cut. Conversely, if the focal length is too short, the laser will cut too deeply into the leather, potentially leaving burn marks.
4. Use Proper Air Assist Nozzle Size
The air assist nozzle size of the laser is also an important factor when laser cutting leather. The too-small nozzle can cause the laser to overheat, leading to burning marks on the leather. On the other hand, a nozzle that is too large can cause the laser to underperform, resulting in a poor cut. It is important to use the appropriate air assist nozzle size for your laser cutter.
