3D Models + Technology
Fabricated foam models (from small to extremely large) can be used for all kinds of props, characters, replicas and almost anything else you can think of. These giant models make a statement, showcasing your brand in new and creative ways, facilitates learning opportunities, and bring brands and consumers together in a way no other form of advertising can. They could even boost social media stats as people share the ever-popular ‘selfie’ with their friends and family. Foam models can get consumers of all ages involved in the experience and interested in what your brand has to offer.
Have you ever wondered how they built that creative show backdrop, or how they created that spine-chilling creature in the trade show booth, or how that jaw-dropping 15′ tall statue in the lobby was built? Since the olden days, those types of models/objects have been built from a special foam. Typically polystyrene foam is used, characterized by its tough, lightweight, and economical nature. 2 lb density works as the best compromise in affordability, ease of use, and durability. A balance between the density of foam is important, as lower density foam is easier to cut and manipulate whilst a higher density allows for a finer carving of details. That comes at a cost however, as the lighter, low-density nature of the foam makes it prone to damages such as cracking or shedding. Be sure to treat your foam models with care!
In addition to the material, creation of form models require sculpting, carving, special finishes, coatings, and various other skill sets to build these unique models. Examples of these include a grid system to mark the areas in need of sculpting, use of a heated wire and other small tools to carve the foam, and the use of epoxy clay to add even finer details. No one utilizes these skills better than our team of sculptors – they bring large-scale models to life, making the imagination reality and creating the ultimate experience. We are dedicated to making your vision come true!
Here are some specific types of foam model fabrication that WhiteClouds is involved with:
Types of Foam Models
When walking down the toy aisle in the local retail store, have you ever wondered what a really big character toy would look like? This is where foam character models come into play. Need a towering transformer character, a giant T-rex skull, or a giant Halo 5 video game character? Foam is a great material for sculptors to use in building life-size or super life-size characters for tradeshow displays, tourneys, or that awesome looking hobby room.
Sculptors typically begin the laborious sculpting process with a large block of foam, an electric chain saw, and a maquette (a french word for scale model). The maquette is used to guide the sculptor in making a large-scale replica of the small model. As you can imagine, this process can get very messy very quickly. These finished foam characters can have many different types of finishes from natural organic looking to matte to automotive looking shines.

Foam Sculpting is one of the most popular mediums for sculpting – an art form that produces fast and awesome looking sculptures. Whether for trade shows, museums, theme parks and attractions, retail stores, office complex’s, lobby displays, faux landscape, or special events; foam sculptures can provide a realistic awe-inspiring physical model of the original design.
These foam sculptures can be themed models, statues, animals, creatures, murals, props, architectural, dioramas, letters/numbers, special foam shapes, or unique displays. They can bring-to-life a creature and it’s surroundings, relive your favorite movie scene, attract visitors at a tradeshow, or create that magical environment you have always wanted to participate in. You are only limited by imagination. These sculptures can also be used for tradeshow displays.

Foam Props and Movie Sets
Foam is a great material for creating props, armor, weapons, creatures, and anything that needs to be fabricated quickly and inexpensively. It is very common to see foam being used to create entire movie sets, theater background sets, haunted displays, amusement park backgrounds and structures, and church theming rooms to name a few.
Foam allows for realistic scenery creation or construction of buildings with elaborate background sets. Foam provides the benefits of being lightweight, economical and efficient in terms of fabrication times. Custom shapes can be created to support any type of imagination. Curious of what movies have used foam in their movie sets? A small list of movies and television shows that have used foam for scenery are: Alien and Aliens, Star Trek – The Next Generation, Battle Star Gallactica, CSI:Miami, The Matrix, Lord of the Rings, Ghostbusters, Batman, Night at the Museum, Eight Below, Jaws, Star Wars, Final Destination 3, Pirates of the Caribbean, James Bond, Saving Private Ryan, Smallville, Harry Potter, X-Men, and many others. Broadway shows that have used foam in the scenery are: Lion King, Mary Poppins, The little Mermaid, Phantom of the Opera, Blue Man Group, Les Miserables, and Beauty and the Beast.

Foam Letters and Foam Numbers
Large letters, sometimes combined with large numbers, are ideal for making a very bold emphasis on a brand, product, or message. When these letters and numbers are combined to make a words or messages, they can be used in many types of oversized displays. At trade shows, these huge words serve as a magnet to attract large crowds and to stand-out amongst myriads of other trade show booths. Retail stores can use them for visual marketing and product branding. Special events can use large letters, numbers, and words clearly identify the main message points.
The craze today is the ever-popular selfie – various uses of large foam letters can immerse you right into the letters and increase your social media effectiveness. Imagine standing in the middle of a 10′ tall word, replacing the “I” letter with your body – great for a selfie. Inserting a specially constructed chair hidden inside a large letter “O” or “G” can make for a great photo-shooting scene.
Foam Letters Galleries
Foam can be used for all types of architectural shapes and settings. Foam architectural structures can be built to emulate entire buildings and even older style cities. Sometimes foam can be used in building architectural scale massing models.
Foam is also commonly used to build all types of architectural elements in new construction from columns, trim, crown molding, arches, caps, brackets, special molding, ceiling accents, railings, shutters, louvres, corbels, medallions, panels, and much more. This special architectural fabrication can be used for outdoor pools, fireplaces, all exterior features of new construction, and even special theming in rooms or the backyard.
A little bit of imagination can bring elegance and beauty to any architectural construction project. EPS foam along with Polyurethane and sometimes cement, can create awesome looking architectural structures.

Steps to Create a Foam Model
- Choosing the correct foam: Most foam sculptors use polystyrene foam, specifically EPS or expanded polystyrene foam. Some sculptors will use XPS or extruded polystyrene foam (sometimes called “blue foam” or “pink foam”) commonly known by its most popular brand name, Styrofoam – it can be purchased in home improvement stores. We would recommend using EPS. These can be purchased in sheets and glued together to make thicker pieces, or can be purchased in very large blocks, or everything in-between. You can easily insert dowels, PVC, or metal rods into pieces to give them extra support in holding them together. Polystyrene foam comes in common densities ranging from 1 lb to 3 lb. 2 lb density works really well for the best compromise in affordability (lower density is cheapest), ease of use (lower density is easier to cut and manipulate), and durability (higher density allows you to carve finer details).
- Sculpting the foam: Most sculptors draw a grid system on the foam before starting the sculpting process. This grid system can be done a number of different ways – free-hand drawing, using a maquette (scale model) as a guide, printing scaled up gridlines from a 3d design and applying them to the foam, or projecting a lighted image from a 3d design of a model onto the foam and then tracing the model. Once you are ready to begin sculpting, the Polystyrene foam can be cut with a heated wire (except for cutting through glued pieces), cut with a band saw, carved on a CNC cutter, or can be sculpted with larger electric chain saws for the heavy cutting. Then you can do finer sculpting and sanding with the use of many different types of small hand tools such as “Dremel” tools, die grinders, electric knifes, handsaws, snap-blade knives, saws, rasps, surforms, and many others.
- Applying textures to the foam: You can glue smaller pieces of foam (that were easier to duplicate or carve as a stand-alone) onto the existing model. You can also add acrylic monomer, for example, to emulate wrinkled skin. Using epoxy clay allows you to add/carve extreme detail into your foam model that would have been very difficult directly carving into foam.
- Finish work: There are a lot of methods to finish off the project depending on a number of factors related to project requirements, such as final durability, weather-proofing, temperature, mobility, strength, and flexibility. Typically, you need to seal the surface and apply protective coatings. These finishes may be combinations of painting, air-brushing, flat-to-glossy finishes, natural environment finishes, soft-shell and hard-shell coatings, sealers, and glassing. These can be from latex, acrylic, urethane, polyurea, epsilon, styrospray, polyurethane, and many others.
How is Foam Created?
Polystyrene plastic starts with very small pellets (raw beads) about a millimeter in diameter.
The first step involves expanding these pellets to about 40 times their original size – this is done inside of a steam chamber where heat (about 400 degrees Fahrenheit) allows pentane gas to escape, then air enters the pellets and inflates them. These expanded Polystyrene pellets look like small puffed styrofoam BB’s. These polystyrene BB’s are then put into bags for storage and the next step.
The second step is another manufacturing process where these BB’s are then poured into a block mold machine. The more BB’s that are put into the hopper, the denser the final foam will be. These BB’s are then steam-fused together into a large block, sometimes as long as 24 feet and as wide/deep as 4 feet x 3 feet. The molding process occurs fairly quickly in about 5 to 20 minutes, depending on density.
Common densities of the now Expanded Polystyrene (EPS) are 1lb, 2lb, and 3lb per cubic foot. There are other special densities that can also be molded, some as small as .5 lb up to 6 lb. These large blocks of foam can weigh anywhere from 300 to 900 pounds.
These large blocks are stored or shipped for later cutting into more common sheet sizes or special shapes. This cutting process is usually done with heated wires that easily melt through the EPS foam – similar in concept to a warm knife slicing through butter. At this point, there are hundreds of uses for these finished sheets of EPS foam.
