Modern manufacturing requires the use of powerful machinery capable of cutting through materials like metal and wood with impeccable accuracy. Two leading methods, laser cutting and plasma cutting, offer distinct advantages tailored to various applications. While laser cutting is renowned for its precision and fine detail, plasma cutting delivers speed and versatility for thicker materials.
At Hornet, we proudly offer 100% American-made cutting machines manufactured in Valley Center, Kansas, and distributed to businesses and organizations around the world. Let’s take a look at these two popular cutting systems to help you determine which is best suited for you.
How Does Laser Cutting Work?
Laser cutting is a commonly used manufacturing process that uses a focused beam of light (laser) to cut or engrave materials. Depending on the machine, the highly concentrated beam of light may rely on gases, fiber optics, or solid-state materials to heat the desired material to the point of melting or vaporization. This innovative process allows the material to be cut or etched with precision. Laser cutters can accurately cut a range of materials, such as metal, wood, and plastic.
How Does Plasma Cutting Work?
Plasma cutting is a powerful cutting process that uses a heated jet of ionized gas (plasma) to cut through electronically conductive materials. These machines create an electric arc that ionizes the gas (usually argon, nitrogen, or air) that flows through the torch, turning it into plasma. The plasma is then forced through a narrow nozzle in the torch where it can reach temperatures of up to 30,000 degrees Fahrenheit. Unlike laser cutters which can cut a variety of materials, plasma cutting machines can only cut electronically conductive materials, such as stainless steel, copper, and aluminum.
Comparing Laser and Plasma Cutting
While both laser and plasma cutting machines use “thermal cutting” methods to cut and engrave materials, this is where their similarities end. Each type of machine carries its own unique advantages and drawbacks, and the right technique for your project will depend on factors such as the material being cut and the level of precision needed. It’s also important to compare processes, materials compatibility, and operational costs.
To meet the needs of our clients, Hornet offers a variety of cutting machines, ranging from Bodor laser cutters to industry-leading CNC plasma cutters powered by Hypertherm. Our team of industry experts can answer any questions you have about our systems and help you choose the most efficient cutting system for your needs.

Versatility
Laser cutters generally reign supreme in terms of versatility, primarily due to their wider material range. Plasma cutters can only cut materials that conduct electricity, which is limited to certain metals. This is because lasers use a beam of light to cut, which is effective on a wide range of materials, while plasma cutters use electrically conductive gas to create cuts.
When comparing thermal cutting machines, consider the types of materials you’ll be cutting. For example, lasers cannot cut highly reflective materials like copper, making a plasma cutter the better option. However, laser cutting has a tighter tolerance of .002 inches, making it better suited for precise cuts or pieces that require intricate notching.
Accuracy
Accuracy is of the utmost importance when manufacturing goods. Lasers have the benefit of being very precise due to their level of concentration, making them overall more accurate than plasma cutters which are very high energy and less focused. As lasers concentrate on just a small area, the cut is smoother and on-point
Plasma cutters tend to not be as accurate as laser cutters as they tend to have a larger kerf for the cut, often leading to larger holes in the material. As they remove more material overall, plasma cutters tend to create more residue and slag than their laser counterparts. If precision is not important, a plasma cutter can be a powerful solution.
Quality
The quality of the cut is highly dependent on the power of the cutting machine. Plasma cutters are excellent for cutting thicker materials that may be difficult to cut using other cutting processes. The plasma arc typically causes a 0.5 to 1.5-degree angle at the vertical cross-section, which can sometimes leave unwanted burrs or a rough edge. A laser cutter can generally offer better quality and more favorable outcomes.
The focused beam of light used by laser cutters creates clean, precise cuts with a repositioning accuracy of 0.02 mm and a positioning accuracy of 0.05 mm. This results in little to no burrs and a smooth edge. There is also less warping in metals when cut by lasers as laser cutters produce less heat compared to plasma cutters. At Hornet, our Bodor laser cutting systems meet international standards such as CE, FDA, SGS, and ISO9001.
Speed
Comparing the speed of a laser cutter and a plasma machine can show how powerful each option is and what you can expect in terms of performance. Laser cutting is generally faster than plasma cutting, especially when cutting thinner materials. However, plasma cutting can cut thicker materials faster than a laser, which is limited in the thickness of materials it can effectively cut.
The type of material being cut also determines the speed at which it is cut and the overall power of the machine. If speed is important for your project and the material is thin or non-electrically conductive, laser cutting may be the best option for your project. If you’re focusing on cost-effectiveness and need thicker materials to be cut, plasma cutting is the most suitable choice.
Power Consumption
When comparing laser and plasma cutters in terms of what’s more powerful, power consumption is an important component to consider. Plasma cutters generally use more power than laser cutters. Laser cutters also cost less to operate as they use less energy without compromising on cut quality. Over time, these energy savings can be quite substantial.
Unlike traditional cutting methods, laser cutters can cut materials without physical contact. This helps expand the lifespan of the machine and results in reduced maintenance costs. In addition, laser cutters are primarily automated and require minimal operator intervention, which can lead to lower labor costs and greater productivity.
