Laser cutting and engraving have various industrial uses, as well as being a popular hobby at the same time. Diode lasers stand out as the go-to tools of choice for at-home hobbyists and enthusiasts due to their compact size, versatility and affordable pricing. They are suitable for popular surfaces like wood, but the question is, does that include softer materials like leather?

The short answer is yes; however, there are certain things to keep in mind, including securing optimal conditions for the procedure, choosing the right device, and avoiding certain health risks. But let’s not get ahead of ourselves - you can read all about these in today’s post where I’ll share everything you need to know, even as a complete beginner.

Understanding laser cutting and engraving

Laser cutting and engraving are delicate processes that require a fair amount of precision, even on flat and hardened surfaces. Therefore, introducing additional challenges in the form of unstable surfaces (such as in the case of leather) can potentially complicate the equation.

The reason being is that the procedure heavily relies on laser beams to vaporize or etch materials. To cut or engrave leather, we need to make sure that the material gets heated enough for this to be made possible, allowing for clean cuts and detailed engravings to be made.

Types of lasers that are suitable for leather surfaces

As far as leather engraving goes, there are two recommended options at your disposal:

CO2 lasers

Among their advantages are versatility, a high power output, and the fact that, besides leather, they can handle a wide range of materials. On top of that, they are suitable for large-scale operations, effectively allowing you to potentially turn your passion into an industrial level business. High precision and speed tend to be their defining attributes. Their power can often exceed 50W.

Diode lasers

Compared to CO2 lasers, diode lasers are much smaller in comparison and they tend to pack a lighter punch (anything from 5W to 40W). However, they are on the affordable end of the spectrum; that, combined with their compact dimensions, makes them more than fitting for at-home use. Under the right conditions, they are suitable for working with leather.

Keep in mind that engraving leather generally requires less power than cutting it, which makes diode lasers the perfect tools for the job. Set them correctly, and they can even tackle curved leather surfaces with utmost precision. Based on my experience, CO2 lasers are the preferred choice for factory owners and similar, while diode lasers lead the way as far as setting up a small business or enjoying a hobby goes.

Are diode lasers suitable for cutting or engraving leather?

Yes, but there are certain limitations to keep in mind. In other words, we need to ensure the following suitable conditions:

- Power requirements. Lower-power models typically range from 5W-10W and this may not be sufficient to effectively cut through thicker leather. Aim for higher-power diode lasers in the range of 20W-40W, as these are generally suitable even for cutting through thicker leather surfaces. From my personal experience, 20W tends to be the sweet spot for working with leather materials of all shapes, sizes, and makings.

- Speed and precision. To ensure a higher level of precision and ensure clean cuts, we need to slow down the process accordingly. However, the extra consistency is well worth the tradeoff of the process taking longer to complete. 

- Material compatibility. Not all types of leather are suitable for the purpose. Generally speaking, full-grain and top-grain leathers tend to work best. Avoid synthetic types of leather such as PVC as it can emit toxic fumes. Instead, consider going with vegetable-tanned leather due to its organic composition.

Best practices for cutting and engraving leather

For optimal results when working with leather, it’s recommended to follow the best industry practices.

1. Select the correct materials. We recommend full-grain or top-grain leather as these tend to be the easiest to work with.

2. Choose the correct power and speed settings on your engraving laser. Adjust them based on the thickness of the leather that you’re working with. Generally speaking, opting for lower speed ensures a higher degree of precision.

3. Equip your device with air assist (to pick up debris). This will ensure that excess debris gets out of the way and that you will experience zero burn marks in the process. Speaking of which, adjusting the laser focus settings also goes a long way towards preventing these and so does cleaning the surface before you begin.

4. Ensure proper safety measures. If you’re working with potentially toxic materials, ventilation is key.

Pro tip: Thanks to its 3-stage filtration system, TOOCAA smoke purifier will make sure that no toxic emissions remain in the room after using your laser engraving machine. It’s quiet and extremely easy to install.

Advantages of using diode lasers for cutting leather

The great thing about picking diode lasers as your tool of choice is that you get to utilize their several key advantages:

- Affordability. Putting them side-by-side with their CO2 alternatives, diode lasers come out on top as the budget-friendlier option. This makes them the preferred choice among hobbyists and DIY enthusiasts.

- Compact design. Irrespective of the space you have available in your workshop or at home, chances are you’ll be able to fit one of these in without making excessive adjustments. This makes diode lasers a suitable choice for condos and small living spaces.

- Versatility. Apart from being able to cut or engrave leather, investing in a diode laser also gives you the right tool you need to work with several other materials, including wood, fabric, acrylic and more.

Does engraving or cutting leather with a desktop diode laser have any limitations?

Depending on all the variables that go into the equation (the type of leather, your device and the rest we’ve discussed), there are certain risks and limitations involved:

- Carbonization. Choose the wrong settings for the job, and burn marks can occur on the edges of the cut leather. Typically, this tends to be an issue with higher power settings.

- Certain diode laser brands may not provide the cut quality you’re looking for when compared to CO2 alternatives.

- Efficiency. Generally speaking, diode lasers typically take longer to complete the job simply due to having a lower power density. However, this is only a limitation in the context of mass-scale operations.

I wanna also introduce a video to you, which maybe very useful for beginners I think! The video introduces how to use a diode laser cutter to cut leather, including methods for fixing the leather with a honeycomb bed, preventing edge burning, and cleaning the laser lens to ensure cutting effectiveness. Moistening the leather can reduce smoke damage and improve cutting quality, while using magnets and popsicle sticks helps secure thinner leather.
