Acrylic is the workhorse material of the Dubai signage and display industry — used for everything from simple flat-cut letters to complex illuminated cabinets and museum-grade display fixtures. Its cost per piece can vary by a factor of five or more depending on four variables: sheet thickness, CNC cutting complexity, finishing and polishing, and whether illumination is integrated into the piece. Understanding these drivers helps you specify (and budget) acrylic fabrication accurately instead of being surprised by the quote.
Sheet Thickness and Grade
Cast acrylic sheet is sold in a range of thicknesses, typically from 3mm up to 25mm and beyond for structural or display applications. Thicker sheet costs more per square metre and is harder to CNC-route cleanly, which adds machine time. Cast acrylic (versus extruded) also costs more but machines and polishes to a noticeably better finish — extruded sheet is more prone to stress-cracking at cut edges, which matters for anything load-bearing or exposed to Dubai’s heat cycling.
CNC Complexity
A rectangular panel cut on a CNC router is inexpensive per piece. The moment you introduce fine detail — dimensional lettering with tight internal radii, pierced or fretwork patterns, multi-layer laminated builds, or 3D-formed (vacuum or line-bent) shapes — machine time per piece rises sharply, and small-radius detail increases the risk of chipping, which affects yield. Complex CNC jobs are usually quoted per hour of machine time plus material, rather than per square metre, once detail passes a certain threshold.
Finishing and Polishing
A CNC-cut edge comes off the router with a visible tool mark. Flame polishing (for cast acrylic) or diamond/mechanical polishing brings the edge to an optically clear, jewellery-grade finish — this is standard for illuminated letters and premium retail display work, and it adds a labour step per piece that scales with total edge length, not just panel size. Sandblasted, frosted, or painted finishes add further steps and drying/curing time.
Illumination Integration
Non-illuminated acrylic fabrication is priced on material and machining alone. The moment LED modules, edge-lighting, or a diffusion layer are built into the piece, you add electrical components, a power supply, wiring routed invisibly through the acrylic body or backing, and testing — this is typically the single biggest cost jump in acrylic signage and display work.
| Cost Driver | Lower Cost | Higher Cost |
|---|---|---|
| Sheet thickness | 3–6mm | 15–25mm+ |
| Sheet type | Extruded | Cast, UV-stabilised |
| CNC complexity | Simple rectilinear cuts | Fine detail, 3D-formed, laminated |
| Finishing | As-cut edge | Flame or diamond polished, painted |
| Illumination | None | Edge-lit or face-lit with driver and diffusion |
Why Two Quotes for the “Same” Piece Can Differ Sharply
- One quote specifies cast acrylic, the other extruded — a real material difference that will show up in edge clarity and long-term UV resistance
- One includes flame polishing on every visible edge, the other leaves the as-cut finish
- One accounts for the actual machine time a detailed cut pattern requires, the other under-estimates it and will likely revise upward mid-job
- One bundles LED driver, wiring and testing into the price, the other quotes the acrylic shell only and treats illumination as a separate line item
Getting an Accurate Quote
The most useful thing you can do when requesting an acrylic fabrication quote is specify sheet type and thickness, provide a clear cut file or reference drawing showing the level of detail, state the finish you expect on visible edges, and confirm whether illumination is required. A contractor working from vague dimensions and no drawing will either overprice for safety or underprice and revise later — neither helps you plan a budget.
Frequently Asked Questions
Is cast acrylic always worth the extra cost over extruded?
For anything illuminated, exposed to direct sun, or requiring a polished edge, yes — cast acrylic holds its clarity and dimensional stability better under Dubai’s heat and UV exposure. For simple painted or backed panels not exposed to weathering, extruded can be a reasonable cost-saving choice.
Does acrylic yellow over time in Dubai’s climate?
Standard cast and extruded acrylic can yellow under prolonged UV exposure. UV-stabilised acrylic grades resist this significantly better and are worth specifying for any outdoor-facing application.
How much does polishing add to the cost?
It depends on total edge length rather than panel area, so a piece with many small cut-outs or fine lettering will see a proportionally larger cost increase from polishing than a single large panel.
Can acrylic fabrication be combined with metal or wood elements?
Yes — composite builds combining acrylic with brushed metal, wood veneer, or painted MDF are common in retail and corporate display work, and are priced as a combination of each material’s fabrication cost plus assembly time.
