When you’ve got a whole studio of talented sculptors working to elevate foam carving to a fine art, precision matters! Whether the Smash Design crew is creating a 10-foot product replica or intricate foam letters for a brand activation, the difference between good and spectacular often comes down to the details.
We like to think we’re at the forefront of a foam carving revolution driven by the power of large-format CNC routers. These amazing, automated robots are transforming what was once a slow, manual craft into a high-tech art form that delivers museum-quality results at speed of marketing!
Let’s dive into how we do it:
The Technology Behind Modern Foam Carving
Large-format computer numerical control (CNC) routers have proven to be a total game-changer in foam sculpture creation. These industrial-scale machines can carve blocks of EPS foam up to 20 feet long with tolerances measured in fractions of millimeters. Imagine a robot sculptor that never gets tired, never second-guesses a measurement, and can recreate your exact, 3D design specifications every single time.
At Smash Design, our CNC routers work kind of like giant, hyper-precise 3D printers in reverse. Instead of building up material layer by layer, they carve away foam with surgical precision, following digital pathways that translate the wildest creative concepts into physical reality. The result? Foam carving that captures every curve, angle, and subtle brand detail you’ve dreamed up.

From Digital Design to Massive Physical Object
The magic of CNC-powered foam carving begins long before our routers start humming. Our process starts with each client’s vision, whether that’s oversized foam letters spelling out a festival name or a titanic foam sculpture showcasing your latest product launch. Our designers convert these concepts into 3D digital models, optimizing every element for both visual impact and structural integrity.
This digital-first approach means we can show you exactly what your foam sculpture will look like before we cut a single block. Need to adjust the curve of a letter? Want to add texture to a surface? These changes happen in minutes on screen, not hours in the workshop. This precision planning ensures that when our CNC routers begin their foam carving dance, they’re creating exactly what you approved. No surprises, no approximations!
Intricate Details at Massive Scale
We still do plenty of sculpting by hand! But traditional foam carving methods hit their limits when brands demand both size and detail. Try hand-carving perfectly uniform eight-foot foam letters on a short timeframe, and you’ll understand why CNC technology is revolutionary. Our large-format routers don’t just handle big; they excel at the seemingly impossible combination of massive scale and minute detail.

Take this project, creating a giant sneaker foam sculpture. The CNC router captured every stitch line, every texture variation, every Nike logo placement with a level of perfection that would take master craftspeople weeks to achieve by hand. At Smash Design, we regularly produce foam carving projects featuring:
- Typography with perfect letterform consistency across any size
- Product replicas accurate down to the smallest design elements
- Architectural details that maintain proportions at 10x scale
- Complex organic shapes that would be impossible to hand-sculpt uniformly
Basically, Smash Design brings digital design into the world of foam carving, and there’s no one better at it than our seasoned team.
Speed and Consistency: The Business Case for CNC Foam Carving
In experiential marketing, timing is everything. Launch windows are tight, event dates are fixed, and opportunities don’t wait. Our large-format CNC routers help us compress production timelines dramatically. What once took weeks of manual foam sculpture work now happens in days. Need 50 identical foam letters for a multi-city tour? Our CNC systems ensure the “A” in Atlanta matches the “A” in Austin perfectly.
This consistency extends beyond just appearance. CNC-carved foam sculpture pieces fit together precisely, ship predictably, and install smoothly—crucial factors when your activation team is working against the clock in Times Square or setting up at Coachella.
