Types of Acrylic Suitable for Laser Cutting & Laser Engraving
A Comprehensive Guide
Acrylic is a versatile thermoplastic material that can be laser cut and engraved with precision and detail. It comes in a variety of forms, including cast and extruded acrylic sheets, tubes, and rods. However, not all types of acrylic are suitable for laser processing. In this article, we will explore the different types of acrylic that can be laser processed and their properties.
Cast Acrylic:
Cast acrylic is the most popular form of acrylic that is widely used in laser cutting and engraving. It is made by pouring liquid acrylic into a mold and then allowing it to cool and solidify. Cast acrylic has excellent optical clarity, and it is available in various thicknesses and colors. It is ideal for producing intricate designs and high-quality engraved marks.
Extruded Acrylic:
Extruded acrylic is made by pushing the acrylic through a die, creating a continuous length of acrylic. It is less expensive than cast acrylic and has a lower melting point, which makes it easier to cut with a laser. However, it has a higher tolerance for color variation and is less clear than cast acrylic. Extruded acrylic is suitable for simple designs that do not require high-quality engraving.

Frosted Acrylic:
Frosted acrylic is a type of cast acrylic that has a matte finish. It is produced by sandblasting or chemically etching the surface of the acrylic. The frosted surface diffuses light and gives a subtle, elegant effect when laser engraved. Frosted acrylic is suitable for creating signage, displays, and decorative objects.
Transparent Acrylic:
Transparent acrylic is a type of cast acrylic that has excellent optical clarity. It is ideal for laser engraving detailed designs and text that require a high degree of precision. Transparent acrylic can be used to create decorative items, jewelry, and signage.
Mirror Acrylic:
Mirror acrylic is a type of cast acrylic that has a reflective surface. It is produced by vacuum depositing a thin layer of metal onto one side of the acrylic. The reflective surface gives a stunning effect when laser engraved, creating a beautiful contrast between the engraved and non-engraved areas. Mirror acrylic is ideal for producing decorative objects and signage.
Recommended Laser Machine for Acrylic
When laser processing acrylic, it is essential to adjust the laser settings according to the type and thickness of the material. The power, speed, and frequency of the laser should be set to ensure a clean cut or engraving without melting or burning the acrylic.
In conclusion, the type of acrylic chosen for laser cutting and engraving will depend on the intended application and design. Cast acrylic is ideal for producing high-quality engraved marks and intricate designs, while extruded acrylic is more suitable for simple designs. Frosted, transparent, and mirror acrylic offer unique and stunning effects when laser engraved. With the right laser settings and techniques, acrylic can be a versatile and beautiful material for laser processing.
