# Acrylic vs ACM (Composite) for 3D Letters

Acrylic and aluminium-composite material (ACM) can serve different roles in a dimensional-sign construction. Choose by the result and component specification rather than a fixed size or cost threshold.

## When to consider acrylic

- A clear, coloured or translucent face is needed.
- The design includes an illuminated face with a suitable acrylic grade.
- The proposed thickness and mounting suit the letter or panel.

## When to consider ACM

- An opaque composite panel or sign component suits the design.
- The panel finish and thickness meet the fabrication requirements.
- The selected grade is specified for the installation environment.

## Side-by-side

| Criterion | Acrylic | ACM |
| --- | --- | --- |
| Light transmission | Clear or translucent grades available | Opaque panel construction |
| Weight | Depends on grade and thickness | Depends on panel construction and thickness |
| Outdoor suitability | Confirm sheet grade, finish and mounting | Confirm panel grade, finish and mounting |
| Cost | Quote the finished component and installation | Quote the finished component and installation |

Use a translucent face where light needs to pass through it. For an opaque component, compare the appearance and fabrication options at the same dimensions. Halo lighting and mounting are design decisions for the complete assembly.
