What Makes Acrylic 3D Letters So Popular?
Businesses prefer acrylic illuminated letters because they offer:
- A premium modern finish
- Long-lasting illumination
- High clarity and sharp edges
- Suitability for both indoor and outdoor use
- Energy-efficient LED performance
Unlike traditional boards, Acrylic LED Letters offer a 3D sculpted look that stands out day and night.
Materials Used in Acrylic LED Signs Boards
The quality of materials directly impacts:
- Brightness
- Weather resistance
- Sharpness of edges
- Durability
- Price
Common materials include:
- Cast Acrylic Sheets (2mm–20mm)
- LED Modules (waterproof/indoor variants)
- Aluminum/SS Back Plate (optional)
- Diffusion Film (for uniform glow)
- Premium Adhesives & Laser Finishing Consumables
- Mounting Hardware (studs, screws, brackets)
Premium projects also use silicon sealing, high-density LED modules, CNC-polished edges, and IP67-grade waterproofing for outdoor installations.
Step-by-Step Manufacturing Process
Here’s how Acrylic LED 3D Letters are manufactured professionally:
Step 1: Client Branding Inputs & Measurement
- Brand guidelines
- Font precision
- Exact sizing
- Installation location (indoor/outdoor/front-lit/backlit)
This step ensures the signage aligns with brand standards and space layout.
Step 2: CAD Design & CNC Laser Programming
The logo or text is converted into a precise digital file.
This ensures:
- Smooth curves
- Accurate measurements
- Exact depth layer mapping
Step 3: CNC / Laser Cutting the Acrylic Base
A high-precision CNC/laser machine cuts the acrylic sheet into the exact letter shape.
This ensures:
- Smooth finish
- Sharp corner accuracy
- Perfect brand alignment
Step 4: Edge Polishing & Surface Refinement
Premium manufacturing includes:
- Diamond-edge polishing
- Flame finishing techniques
This step gives letters a glass-like finish, making them look expensive and premium.
Step 5: LED Lighting Integration
LED modules or strips are installed inside the letter cavity.
Illumination variants include:
- Front-lit
- Backlit (halo glow)
- Side glow
- Dual illumination (front + back)
Quality LED modules determine:
- Brightness
- Consistency
- Energy consumption
- Lifespan
Step 6: Sealing & Weather Protection
For outdoor signs:
- Waterproof coatings
- Heat-resistant layers
- Dust protection
- Power supply stabilization
This ensures performance under sun, rain, and humidity.
Step 7: Mounting System & Installation
Final installation varies based on the site:
- Direct wall installation
- Raised/stand-off installation
- Raceway-mounted installation
Precision installation ensures alignment and stability.
Cost Breakdown: Why Pricing Varies
The cost of LED Acrylic 3D Letters depends on several factors:
- Letter Height & Thickness: Larger and thicker letters require more acrylic and structural support, increasing the price.
- Illumination Style: Single front-lit letters are more affordable, while backlit or dual-lit signage costs more due to additional LEDs, wiring, and finishing.
- LED Module Type: Premium waterproof IP67 modules designed for outdoor use are generally costlier than standard indoor LEDs.
- Installation Height & Complexity: High facades or uneven surfaces require extra labor, scaffolding, and safety support, which adds to the cost.
- Finishing Type: Matte, glossy, metallic-coated, dual-layer acrylic, or polished edges can significantly affect pricing depending on the desired look and durability.
Here’s an approximate cost range based on standard market pricing:
- Basic Indoor Acrylic LED Letters: ₹1,800 – ₹3,200 per sq.ft
- Premium Front-Lit Letters: ₹3,500 – ₹5,500 per sq.ft
- Backlit Halo Glow Signage: ₹4,500 – ₹7,500 per sq.ft
- Dual-Lit (Front + Back Glow): ₹6,000 – ₹10,000+ per sq.ft
Outdoor installation, large-size letters, or complex branding may increase costs.
Lifespan & Maintenance
- LED lifespan: 35,000 to 50,000 hours
- Acrylic lifespan: 5–10+ years, depending on exposure
- Maintenance requirement: Minimal cleaning + occasional wiring checks
