Laser Cutter Acrylic: Everything You Need to Know

What is Acrylic and Its Properties?

Acrylic, also known as Poly(methyl methacrylate) or PMMA, is a transparent thermoplastic often used as a lightweight or shatter-resistant alternative to glass. Its optical clarity, high tensile strength, and weather-resistant properties make it ideal for a variety of applications. Acrylic is also characterized by its ability to be sanded and buffed to a glossy finish, lending itself to aesthetic uses. The material exhibits low water absorption, good electrical resistivity, and fair tensile strength. However, due to its brittle nature, acrylic can be susceptible to cracking or shattering under extreme stress or at lower temperatures.

Understanding the Composition of Acrylic

Acrylic, chemically represented as (C5O2H8)n, is a polymer of methyl methacrylate (MMA). Its molecular structure comprises a long chain of polymers, with each polymer consisting of repeating units of methyl methacrylate. MMA in its monomer state is a colorless and transparent fluid that polymerizes easily to form acrylic. The polymerization process involves the use of catalysts, typically organic peroxide compounds, and heat to trigger a reaction where multiple MMA molecules link together to form long polymer chains. This process creates a solid, translucent material known for its robustness and clarity.

Different Types of Acrylic for Laser Cutting

In terms of laser cutting, it’s crucial to understand that acrylic comes in two primary types – cast and extruded – each with its unique characteristics and benefits.
