In the advertising industry, foam 3D models often appear. So, what are the classifications of foam 3D models? What are the processing techniques? Let me share with you today!

Classification of foam：

1. According to thickness, it can be generally divided into: 3 cm foam, 5 cm foam, 10 cm foam, 20 cm foam, 40 cm foam, 50 cm foam. For making three-dimensional foam characters, 5, 10, and 20 cm thick foams are the most commonly used.

   
   

2. According to density, it can be divided into: low foaming, medium foaming, and high foaming foam. Foams with a density less than 0.1g/cm³ are called high foaming foams, foams with a density between 0.1 and 0.4g/cm³ are called medium foaming foams, and foams with a density greater than 0.4g/cm³ are called low foaming foams.

3. According to hardness, it can be divided into: soft foam, semi-hard foam, and hard foam. Generally speaking, soft foams are relatively soft at room temperature.

Classification of foam three-dimensional shapes：

Foam three-dimensional 3d characters/3d foam letters:

Sizes and thicknesses can be easily made, including bevels, special-shaped characters, 3D shapes, etc. Foam three-dimensional 3d characters have evolved from a single festival decoration shape to diversified development. With its strong operability and convenience, it has gradually shown its unique charm in exhibitions, image exhibition halls, commercial activities, advertising, festival decorations, art displays, film and television props, models and other fields.

Foam three-dimensional 3d sculptures:

Foam sculpture customization is now widely used in various exhibition venues. Some outdoor advertisements, commercial space layouts, wedding sites, and promotional activities all use this kind of sculpture product. Now many landscapes are gradually using this kind of sculpture to replace some of the original decorations. At present, the craftsmanship of this kind of sculpture has also made rapid progress and gradually met people's needs.

Features of foam three-dimensional 3d modeling:

1. The material is soft and light, and can be processed into super-large shapes without worrying about safety issues;

2. It is easy to process, with a thickness of 5-50 cm or even thicker, and can be customized according to specific usage conditions;

3. It is easy to install and can stand directly on the ground;

4. The surface color is diverse and optional, and the advantage of low price is mostly used in event exhibitions.

Processing technology of 3d foam signs:

The original color of the foam is pure white, and there are many post-processing processes, which are mainly customized according to the needs of consumers.

The foam characters can be sprayed with paint, added with PVC surface, added with acrylic panel, sprayed with real stone paint, hardened, etc.

At the same time, in order to meet the needs of fire safety, B1 and B2 flame-retardant high-strength foam materials are also introduced.

Application scenarios of 3d foam models:

The foam modeling is precise, beautiful, and has a strong three-dimensional sense, which is unique and effective. It is mainly suitable for various festival models, round sculptures, party building cultural models, and art props.

Advertising: 

foam 3D landscape characters, bevel characters, spherical characters, various 3D characters;

Urban landscape: 

square sculptures, art sculptures, garden sculptures, cartoon shapes, etc.;

Exterior wall decoration: 

EPS lines, exterior wall 3D shapes, wall relief shapes, Roman columns, etc.
