Two-layer engraving plastics generally involve a layer of the base materials of another color on the surface layer. When the surface layer is engraved using a laser or another engraving technique, the top layer is removed, exposing the underlying layer of a different color. This is how contrast in the engraved designs is achieved because the surface layer can be of a different color than the base layer.
It is also worth noting that two-layer engraving plastics come in various forms that are suitable for diverse purposes. They include the following types:
Acrylonitrile Butadiene Styrene (ABS) Engraving Plastic
ABS is a thermoplastic engraving machine that is a two-layer plastic material with good toughness and impact resistance. It is very easy to engrave, which gives a smooth finish and rarely leaves bad plastic burns. Common ABS applications include signage and a wide range of consumer products.
Acrylic/PMMA Engraving Plastic
Acrylic, also known as PMMA (Polymethyl methacrylate), is a thermoplastic engraving material that is popular with users due to its clarity and weather resistance. It can be opaque or clear, and when engraved, it gives a polished engraved area that is usually smooth and highly aesthetic. Acrylic plastic finds a lot of applications in trophies, signs, displays, and artistic pieces.

The selection of two-layer engraving plastic depends on several factors that relate to the intended usage, the compatibility of engraving machines, and the desired visual effect. Some of the factors to consider include:
Material Composition
Engraving plastics are manufactured using different materials such as ABS, acrylic, and polycarbonate, which have different physical and mechanical properties. While ABS is impact-resistant and tough, acrylic engraving gives clarity. Polycarbonate, on the other hand, comes with great impact resistance and is heat resistant.
Layer Colors and Contrast
The visibility and clarity of engraving basically depend on how contrasting the two layers are. For sharp engravings with great insight, choose plastics with highly contrasting stock colors. Engraving of two layers acrylic comes with aesthetic appeal in addition to functional purposes; thus, it can be used in awards, signage, or control panels.
Thickness and Size
Two-layer engraving plastics come in different thicknesses and sizes, depending mostly on the nature of the project. Projects that involve intricate designs may require thinner materials, as detailed etching might be difficult on thick plastics. Common sizes for engraving plastic are compatible with standard cutting machine requirements.
Engraving Compatibility
It's always advisable to ensure that the specific type of two-layer acrylic engraving plastic is compatible with the engraving machine being used. Different machines work with different settings, such as speed and power. Therefore, ideally, pre-engraving tests should be done to get the best results.
Finish and Texture
Depending on the purpose of the engraving plastic, the texture and finish can be different. A cleaner, more polished look is preferred for trophies and signage, while a non-reflective finish is ideal for control panels and other functional devices.
Environmental Resistance
Consider the conditions where the engraving will be exposed, such as temperature, humidity, and even UV radiation. In most cases, acrylic engraving plastics are resistant to UV and weather conditions, hence making them ideal for outdoor applications.
Cost and Availability
Two-layer engraving plastics are available at different prices, depending on their material properties that include thickness, size, and environmental resistance. Although two-layer engraving plastics are relatively inexpensive compared to other materials, their cost might vary depending on the thickness, size, and other material properties like environmental resistance.
