EVA foam, also known as Ethylene-Vinyl Acetate foam, is a type of synthetic material that is popularly used for a wide range of applications. It is made by combining ethylene and vinyl acetate under heat and pressure, resulting in a durable, lightweight, and flexible foam material. EVA foam is known for its cushioning and shock-absorbing properties, making it a popular choice for sports equipment, footwear, and crafts.
It is important to have proper ventilation in place when laser cutting EVA foam to remove the fumes from the working area. Adequate ventilation helps maintain a safe working environment by preventing the accumulation of potentially harmful gases and minimizing the odor associated with the process.
A laser cutter, such as a desktop CO2 laser or a fiber laser, is a precise and efficient option for cutting EVA foam, especially for complex or intricate designs. Laser cutters provide clean, sealed edges and are often used for larger-scale projects.
If you have access to a CNC (Computer Numerical Control) router with a suitable cutting tool (such as a rotary tool or knife), it can be used for cutting EVA foam. CNC routers offer precision and can handle thicker foam sheets.

When using water jet cutting, water will be sucked into the absorbent foam during the separation process. Before further processing, the material must be dried, which is a time-consuming process. Laser cutting omits this process and you can continue processing the material immediately. In contrast, the laser is very convincing and is clearly the number one tool for foam processing.
MimoWork’s laser cutting machines for EVA foam are equipped with built-in fume extraction systems that help capture and remove the fumes directly from the cutting area. Alternatively, additional ventilation systems, such as fans or air purifiers, can be used to ensure the removal of fumes during the cutting process.
