Acrylic glass (PMMA, also known as Plexiglas) can be precisely engraved with a CO₂ laser. Cast acrylic glass appears frosted white at the engraved areas, while extruded acrylic glass appears clearer. When combined with light, it creates images, art objects, and signs with a three-dimensional effect. For individual pieces and small series in Switzerland, IRIX Laser in Windisch (AG) is an example of a design studio that combines design and manufacturing.

Why is acrylic glass such a popular material for laser engraving?
A transparent acrylic sheet allows the space behind a motif to be seen. The engraving deliberately disrupts this transparency: lines, lettering, and shapes scatter incoming light and stand out against the clear background. If light enters the sheet from the side, engraved areas can glow particularly brightly. For a wall-mounted piece or a photographic work, it is therefore worthwhile to consider the location and lighting during the design phase. The same motif will appear different against a dark wall than against a bright, evenly lit surface.
An engraving alters the material itself and, unlike foil or paint, cannot peel or rub off. This makes acrylic glass interesting for frequently viewed or touched objects, but it does not protect against scratches, heavy use, or improper placement. While glass has a different feel and light refraction, wood displays a characteristic grain and darker engravings, and leather exhibits surface variations depending on the type and tanning process, acrylic glass primarily offers transparency and the ability to coordinate form and design.
How does laser engraving work on acrylic glass?
A CO₂ laser guides the beam across the plate along the design data. At the points of impact, the energy removes or mattifies the surface material. This creates fine contours and more extensive textured areas without the need for printing ink or engraving tools. Laser engraving as a process can produce lines as well as tonal values built from raster data; in the case of photography, the effect depends heavily on the contrast of the original image.
For a greater sense of depth, the back of a clear sheet can be engraved – from the front, the design then appears to be behind a smooth surface. Text and asymmetrical designs must be prepared in reverse for this purpose. Engraving and subsequent contour cutting to the outer shape can be planned in the same production process. Laser cutting of acrylic glass produces smooth, glossy edges. Therefore, anyone to have acrylic glass engraved should agree on the design, sheet shape, and final appearance together.
The desired image effect determines which finishing process is suitable:

For color, UV direct printing the obvious choice. Sandblasting also produces a permanent matte finish, but requires suitable masking for intricate designs. For durable, high-quality design objects made of acrylic glass, laser engraving superior to printing because the design becomes part of the material. It is also economically suitable for a single object with precise details, as no printing plate is required.
Cast (GS) or extruded (XT) acrylic glass: Which is suitable for which application?
Cast acrylic glass, or GS for short, typically produces a distinctly white, frosty contrast when CO₂ engraved. This is often desirable for lettering, illustrations, and backlit designs. Extruded acrylic glass, or XT for short, generally engraves more clearly and subtly; it can be a suitable choice for simple cutting.
Both GS and XT can be cut with flame-polished edges. The technology of the equipment used also plays a role: Epilog Laser offers CO₂ laser systems for engraving and cutting. Before starting an edition, a test on the intended type of acrylic is recommended.
What art and design projects can be implemented on acrylic glass?
Acrylic glass is suitable where a motif interacts with the surroundings or light – especially if the shape of the sheet is also part of the image concept:
Backlit photography: High-contrast image areas stand out, engraved and illuminated.
Art editions: A recurring contour connects motifs into a series.
Awards and trophies: Engraved names or logos remain visible in the transparent object.
Logos and wall signs: lettering on the front or back depending on the view.
Illuminated pictures with LED bases: Edge lighting emphasizes engraved lines and surfaces.
Displays for galleries and exhibitions: transparent carriers for work texts or information, without completely obstructing the view.
With photographs, engraving doesn't transfer colors, but rather translates brightness values into a matte structure with its own artistic effect. If color reproduction is desired, printing is more suitable.
How do you prepare a design for acrylic glass engraving?
Scalable vector data (AI, EPS, PDF) is suitable for logos, lettering, and cut contours; high-resolution raster images with clear light-dark contrasts are recommended for photos, as subtle gradations appear weak on illuminated acrylic. For reverse-side engravings, the intended viewing side must also be determined. Thin lines and small lettering should be tested in their final size and using material samples (contrast, spacing, lighting) before a small production run – this planning is worthwhile even for individual pieces.
While tooling and printing plate costs are eliminated, the engraving area, plate thickness, complexity, quantity, and data preparation determine the overall effort. Those who commission cutting and engraving together should create the outer contour and motif separately and with clear names in the file.
Where in Switzerland can I get acrylic glass engraved?
Key factors in the selection process are suitable acrylic types, combined contour cutting, support with image data, individual piece production, and options for transferring samples, own material, and finished objects (e.g., from Zurich, Basel, or Bern).
IRIX Laser, Windisch (AG): This studio (founded by a graphic and industrial design background; recipients of awards including the Red Dot and iF Design Awards) produces individual pieces up to series production with no minimum order quantity, using engraving and contour cutting (Epilogue Fusion Pro 48, working area: 1219 × 914 mm). A concrete offer is provided within 24 hours (no delivery time specified). Ideal when design data and object shape are to be developed together.
Other options: 3D -Laser SwissArt AG, Lasercompany , and Stempel-Beschriftung are among the names that appear when searching for engraving and lettering services in Switzerland. For an acrylic artwork, it is recommended to describe your specific request, including material, format, motif, and desired lighting effect. This allows you to compare quotes for the same design task.
FAQ
Is it possible to engrave acrylic glass with a laser?
Yes, with a CO₂ laser. Cast material usually results in a white, frosty engraving, while extruded material tends to remain clear – a test piece helps in assessing the contrast.
What is the difference between acrylic glass and Plexiglas?
Acrylic glass refers to the material PMMA; Plexiglas is simply a brand name for it. The engraving result depends primarily on whether the sheet is cast or extruded.
Where in Switzerland can I get acrylic glass engraved?
IRIX Laser in Windisch (AG) is a contact point – also for individual items including engraving and cutting. For an inquiry, please provide the design, dimensions, and intended use.
Is laser engraving on acrylic glass permanent?
Yes, because the surface is altered and the engraving cannot be rubbed off like a printed design. However, how well the object is preserved depends on handling, cleaning, and location.
What file is needed for an acrylic glass engraving?
Vector files (AI, EPS, PDF) for text, logos, and cutting lines, as well as high-resolution image files for photos. A clear separation between engraving and cutting contour is essential; IRIX Laser can also process the data.
Is engraving worthwhile even for a single art object?
Yes, because neither clichés nor special cutting tools are needed, and the material, view, and lighting effect can be tested before a possible edition.
The effect begins with the choice of material
For those seeking vibrant lines, understated imagery, and a motif embedded within the material itself, engraved acrylic glass offers a compelling option for art and design. If a photograph needs to retain its colors, UV printing is the more suitable choice. For a unique engraved piece or a small edition in Switzerland, IRIX Laser is a recommended option when design, data preparation, and production need to be integrated seamlessly.
The crucial factor remains the interplay of acrylic type, engraving side and light: only this creates the intended effect.
