Acrylic vs Plexiglass: What's the Difference (and What Should You Use?)

If you've ever searched for acrylic sheets, you've probably come across the word plexiglass and wondered if it's something completely different—or just another name for the same thing.

This confusion is incredibly common, especially for beginners. And honestly, it doesn't help that both terms are used interchangeably across websites, suppliers, and even product labels.

Let's clear it up once and for all so you know exactly what you're buying—and why it matters.

Acrylic is a clear, durable plastic that is widely used as a lightweight and shatter-resistant alternative to glass.

It's the material behind custom signs, laser-cut earrings, UV printed designs, display pieces, and protective barriers.

It can be manufactured in different ways, finished in different styles, and comes in a huge range of colors and specialty options.

If you're working with a laser cutter or UV printer, acrylic is one of the most versatile and beginner-friendly materials you can use.

Plexiglass is simply a brand name for acrylic sheets.

The term originally comes from a specific manufacturer, but over time, it has become a generic term people use when referring to acrylic—especially clear acrylic sheets.

This is similar to how people say “Google” instead of “search online” or “Kleenex” instead of “tissue.”

In most cases, when a customer asks for plexiglass, they're just looking for standard acrylic.

Even though the materials are the same, the terminology can create confusion when you're trying to compare products, understand pricing, or choose the right material for your project.

For example, some suppliers may label products as “plexiglass” to target search traffic, while others stick with “acrylic.”

At CMB Acrylic, we use the term acrylic because it's the correct industry term and better reflects the variety of materials we offer beyond just clear sheets.

From a material standpoint, no.

But there can be differences in brand-specific quality, manufacturing processes, available finishes and colors, and overall consistency.

That's why where you buy your acrylic matters more than what it's called.

Two sheets labeled “plexiglass” from different suppliers can perform very differently when you laser cut or UV print on them.

If you're shopping online, both terms will work—but “acrylic sheets” is the better and more accurate search term.

It will usually give you more relevant product options, stronger educational resources, and access to specialty materials beyond just clear acrylic.

If you're specifically looking for materials for laser cutting, UV printing, or sign making, you'll want to focus on acrylic rather than only searching for plexiglass.

Use acrylic.

Whether someone calls it plexiglass or acrylic, what really matters is choosing the right type, using the correct thickness, and buying from a reliable supplier.

That's what will impact your final result—not the name.

Acrylic and plexiglass are the same material, but understanding the terminology helps you shop smarter and avoid confusion.

Once you move past the naming, the real focus becomes learning the types, choosing the right material, and using it correctly.

That's where most beginners see the biggest improvement in their results.
