Ethylene and vinyl acetate are components of the copolymer known as ethylene-vinyl acetic (EVA) foam, also called polyethylene-vinyl acetate (PEVA). 

Machining EVA foam with a laser may be done using either a 9.3 nano or 10.6-micron CO2 laser with little to no discernible change in the overall quality of the procedure. EVA foam does not readily absorb the energy from a 1.06-micron fiber laser. Hence the usage of this laser with this material is not suggested. 

When cutting EVA foam with a CO2 laser, the resulting cut is broad and has a faint brown discoloration in certain places. Using a CO2 laser to perform laser engraving on EVA foam creates depth and a darkened surface, slightly sticky surface, and melted edges. It is not feasible to laser mark EVA foam with 9.3, 10.6, or 1.06-micron wavelengths.

What Exactly is the EVA Foam?

EVA Foam

The substance you are looking at is called EVA, and it is a black foam. Ethylene-vinyl acetate is a kind of copolymer that goes by the acronym EVA. 

This versatile foam that is both soft and hard can be readily laser cut with ZMorph VX, and it also has a wide range of uses, some of which will be discussed in the next portion of this article. 

EVA foam is characterized by very little water absorption and is soft, and has excellent shock absorption properties. We’ll show you how to use EVA when you attach the Laser PRO toolhead to your system and demonstrate how it works.

Does the Laser Have the Capability of Cutting Foam?

Laser Foam Cutting

It is crucial to determine whether or not foam can be cut using a laser machine before investing in a machine specifically designed for cutting foam. Some materials cannot be cut using a laser cutter, even though this method makes it simpler to cut products that are lighter and not as durable. In addition to cutting an item, it is essential to check that the product is not damaged or cracked in any other locations before beginning the cutting process. 

Therefore, although laser cutting may appear to be a simpler and more convenient alternative for cutting, it may require additional concentration to prevent the object from being destroyed.

When you want to cut foam material with a laser, you should be aware that not all types of foam are ideal for laser cutting. Instead, the foam created with polyethylene, polyester, or polyurethane is a better option for laser cutting because of its rigidity. 

After having these different kinds of foams cut using a laser cutter, the result gives you the ability to use the foam in various contexts.

Is It Possible to Use A Laser Cutter On Polyurethane Foam?

Polyurethane Foam

The physical process of eliminating material happens when the material is sliced with a laser. One has the material removed from the top to the bottom, while the other has only a portion of the top removed until it reaches a particular depth.

A very high percentage of the CO2 laser’s energy may be absorbed by polyurethane foam. When high-intensity laser light is absorbed by polyurethane foam, the material immediately begins to transform that light energy into heat at the molecular level. 

The thermoset nature of this particular form of polyurethane foam makes it susceptible to the quick chemical disintegration that can result from sufficient heat. The laser will cause the portion of the substance that it affects to vaporize.

Can You Use a Laser to Cut Different Types of Foam?

Laser engraving and laser cutting are excellent applications for foams comprised of polyurethane, polythene, or polyester. Foam, EVA foam polyurethane, foam board, and other foam varieties are examples of common types of foam materials.

Is EVA Foam Suitable for Being Cut with A Laser?

EVA Foam Suitable

EVA is an acronym that stands for ethylene-vinyl acetate, and it is a copolymer. EVA foam has very low water absorption, high shock absorption, and a soft texture.

EVA foam is frequently utilized for a wide variety of container and casing applications, and it is also adaptable for use in a variety of accessory applications. This foam, which is both soft and hard, maybe readily sliced with a laser.

How Can EVA Foam Be Cut with a Laser Cutter?

Before we begin laser cutting EVA foam, we need to ensure that our health and safety are protected. Even though EVA foam is not a hazardous material, anyone who uses a laser cutter needs to have some protective equipment on hands, such as safety glasses and a laser fume extractor, among other things.

Cutting EVA foam with a laser is a straightforward process, but there are a few things you should know before you begin. If you set the operating speed too fast, it will not cut the material, and if you set it too slow, it will burn the material. The thickness of your EVA foam sheet will determine the number of pathways available to you.

Using a Laser to Cut Through the Foam:

When successfully cutting the foam using a laser cutter and obtaining the necessary foam material, what should you do?
