Custom acrylic, 3D & illuminated letter signs on the Gold Coast

Flat-cut acrylic letters

The everyday workhorse. A single layer of acrylic, CNC-routed or laser-cut to your shape, ready to stud-mount or stick to a wall or panel.

Flat-cut letters are the fastest, most cost-effective way to get crisp, professional letters on a wall, a reception sign, or a shopfront that doesn't need lighting.

• →Thickness drives the look. Thin acrylic (3mm) sits close to the wall and reads clean and modern. Thicker stock (10mm, 12mm and up) throws a shadow and looks more substantial — close to a built-up letter without the cost.
• →Edge finish is where laser and router differ. Laser-cut acrylic comes off the bed with a clear, flame-polished edge straight away. Router-cut acrylic has a matte machined edge that can be flame-polished or left raw depending on the look. We pick the method to suit the material and the finish.
• →Colour and finish. Cast acrylic comes in a big range of colours, opals, frosts and mirror finishes, so the letter can be the finished article with no painting. Clear acrylic with an applied face or paint is the other common route.

Built-up (3D) letters

When you want depth and presence, built-up letters give you a true 3D letter with a face and returns (the sides). They stand proud off the wall and throw a real shadow.

Built-up letters are a step up in fabrication from flat-cut, so they cost more and take longer — but for a hero sign at an entrance, they're worth it.

• →We cut the faces and the return strips from acrylic or ACM, and the letter is fabricated into a box shape.
• →Depth is up to you — a shallow 20–30mm return reads neatly; deeper returns make a bolder architectural statement.
• →These suit feature walls, premium retail, building entries and reception signage where a flat letter would look too thin for the space.

Channel letters & illuminated signage

Channel letters are the illuminated 3D letters you see across shopfronts and building facades — a fabricated letter "can" with LED lighting inside. How they're lit changes the whole look:

Face-lit (front-lit) — the classic illuminated letter. A translucent acrylic face glows when the internal LEDs are on, with the light coming straight out the front. Best all-round day-and-night visibility: the letter reads as a solid colour by day and lights up at night. The acrylic face is the part we cut, secured into the can with a trim cap edge.

Halo-lit (reverse-lit) — an opaque face with the LEDs facing backwards, mounted off the wall so the light spills around the letter and creates a glowing halo behind it. A premium, architectural look that works best on a light, matte wall. The letter itself stays dark; the glow is the effect.

Face-and-halo (combination) — lights both the face and the wall behind for a dual effect. The most striking, and the most involved to build.

A few things worth knowing before you order an illuminated sign:

• →LEDs are the standard. Modern channel letters run low-voltage LED modules off a driver — bright, efficient and long-lived. (We don't do neon.)
• →The cans are usually metal. Traditional channel-letter cans and returns are aluminium. We don't fabricate metal — what we supply is the precision-cut acrylic faces and components, and we work alongside the signwriters who build the cans and install. If you're a signwriter, send us the face artwork and we'll cut it to suit your build.
• →An illuminated sign needs an electrician. Any sign connected to mains power has to be wired in by a licensed electrician. Factor that into the job.

Push-through lightbox signs

A push-through sign is a clean, high-end alternative to channel letters, and one we're set up well for. A solid face panel — usually ACM — has the letters or logo CNC-cut out as voids, and acrylic letters are inserted into those cut-outs so they sit slightly proud of the face. With LEDs behind, the acrylic letters glow while the panel stays solid.

This plays straight to what we do: precise ACM routing for the panel and clean acrylic cutting for the push-through pieces, cut to fit each other tightly. It's a sharp look for reception walls, illuminated shopfront boxes and feature signage.

Choosing the right material

What the letter is made from matters as much as the shape. For the deeper acrylic-versus-ACM breakdown, see our acrylic vs ACM guide. On the cutting side: cast acrylic is the clear pick for routing and engraving, and for laser cutting both cast and extruded come up clean — the better choice there comes down to grade, thickness and how the edge needs to finish, which we'll call on the job.

The short version:

• →Cast acrylic — the premium choice for letters. Big colour range, excellent clarity, machines and engraves cleanly. Our default for quality acrylic letters and illuminated faces.
• →Extruded acrylic — cheaper, fewer finishes, forms more easily if a job needs thermoforming. Fine for plenty of work where cost matters more than finish.
• →ACM (3mm and 4mm) — aluminium composite panel. The go-to for flat panel signage, push-through faces and anything going outdoors permanently. Routed, not lasered.
• →Foam PVC — light, smooth and easy to work; good for interior letters and short-term signage. We only ever route foam PVC, never laser it — lasering PVC releases hazardous fumes, so it's a hard rule.
• →Polycarbonate — when impact resistance matters (high-traffic or vandal-prone spots).

Will it last on the Coast?

The Gold Coast is hard on signage — UV, salt air and humidity all take a toll, and the wrong material can yellow, warp or fade inside a season. We go through this properly in the coastal materials durability guide — worth a read before you commit a sign to full sun.

• →ACM is the workhorse for permanent outdoor signage here — it holds up for years in our climate.
• →Outdoor acrylic should be UV-stabilised so it doesn't yellow.
• →Foam PVC is an interior / short-term material outdoors — it can warp and take on moisture over time.
• →Corflute is short-term only — fine for a few months, but it goes brittle and fades under Queensland sun.

Approvals & compliance

Two things to check before an outdoor or illuminated sign goes up:

• →Council approval. The City of Gold Coast regulates advertising devices. Some signs need a licence (and sometimes planning or building approval) while others are exempt — it depends on the sign type, size and location. Check with the City of Gold Coast before you install; it's easier than fixing it after.
• →Electrical. Any mains-powered illuminated sign must be connected by a licensed electrician.
• →This is general guidance, not legal advice — the council's rules are the final word, so confirm your specific sign with them.

What we do — and don't

To save the back-and-forth — and if you're a signwriter or shopfitter, this is exactly the point: send us the artwork set up right and we'll cut the components to suit your build.

• →We do — CNC routing and laser cutting of acrylic, ACM, foam PVC, polycarbonate, MDF and ply; flat-cut letters; built-up acrylic and ACM letters; illuminated sign faces; push-through panels and components.
• →We don't — metal fabrication, neon, vinyl, or installation. We're the cut-and-fabricate specialist behind the signwriters, not a full sign-and-install shop.

FAQ

Are channel letters and 3D letters the same thing?

Not quite. "3D letters" is the broad term for any dimensional letter that stands off the wall — that includes flat-cut letters in thick stock, built-up letters, and channel letters. "Channel letters" specifically means the illuminated, fabricated cans you light from inside. All channel letters are 3D letters; not all 3D letters are channel letters.

What acrylic is used for sign faces?

Cast acrylic for most quality work — it's clearer, comes in more colours and finishes, and machines cleanly. Translucent cast acrylic is the standard for illuminated faces because it glows evenly.

Can you make the whole illuminated sign?

We make the acrylic and composite components — faces, push-through letters, panels. The metal cans and the install are handled by the signwriter. If you do that side, we're your cutting partner; send us the artwork.

Do I need council approval for a shopfront sign?

Possibly — it depends on the sign and the site. The City of Gold Coast exempts some signs and licenses others. Check with them before installing.

Flat-cut or built-up letters — which should I get?

Flat-cut if you want clean, cost-effective letters and don't need much depth. Built-up if you want a true 3D hero letter with real presence at an entrance. Thick flat-cut acrylic is a good middle ground.
