What Kind of Modelling Medium is Very Stiff and Holds Details/Structure Very Well?

When it comes to creating detailed and structurally sound models, selecting the right modelling medium can make all the difference. While some artists might prefer a soft, pliable material for precise details, others might lean towards stiffer options to provide foundational support. In this article, we will explore two popular modelling mediums—wire armatures and plastic clays such as Milliput and DAS—highlighting their unique advantages and applications.

Wire as an Armature

Wire armatures are a fundamental technique used in clay modelling and sculpture. They serve as the internal support structure, ensuring that the clay holds its shape and that details are preserved. Wire armatures are particularly suitable for larger and more complex models where the internal structure is crucial for maintaining the overall form. Common types of wire used include:

Steel wire: This is one of the most commonly used materials due to its strength and ease of manipulation. Copper wire: Known for its flexibility, copper wire is ideal for intricate details and fine adjustments. Aluminum wire: Lighter and less rigid than steel, it is perfect for models that require extensive detailing without excessive weight.

The process of creating an armature involves shaping the wire to match the intended form of the model. This structural support is then covered with clay, allowing artists to add intricate details without worrying about the internal structure collapsing. Wire armatures are particularly useful in figure modelling, where the internal framework is necessary to create a lifelike, anatomically correct sculpture.

Plastic Clay: Milliput and DAS

On the other hand, there are plastic clays that are renowned for their sturdiness and ability to hold fine details. These materials are often used as the primary or secondary medium to build upon the wire armature or as a standalone material for detailed work. Two highly acclaimed examples are Milliput and DAS.

Milliput

Milliput is a type of reinforced clay that is both flexible and durable. Originally designed for military model building, it has gained popularity among artists for its unique properties. Milliput is excellent for creating intricate details and maintaining structural stability throughout the modelling process. Some of its key features include:

Excellent impact resistance and durability. Can be manipulated easily with minimal tools. Directly applies to wire armature for added support. Increases the strength of the overall model.

Artists often start by building the armature with wire and then cover it with Milliput for a smoother, more detailed result. Milliput’s ability to hold fine details and its resistance to cracking or sagging make it an ideal choice for creating complex sculptures.

DAS

DAS (Diesel-Added-Simulacrum) is another popular plastic clay that is highly rated for its ease of use and structural integrity. DAS is known for its:

High level of flexibility for intricate detailing. Potential to be used over existing armatures or as a standalone material. Ability to combine with other materials such as wire and Milliput. Good airbrushing properties, allowing for realistic paint finishes.

Artists often use DAS to achieve highly realistic and lifelike textures. By mixing DAS with different pigments and mediums, artists can create a wide range of textures and finishes, from smooth and glossy to rough and matte. This flexibility makes DAS a versatile choice for a variety of modelling projects.

Choosing Between Wire and Plastic Clay

The choice between wire armature and plastic clay such as Milliput or DAS depends on the specific requirements of the project. For detailed and structurally complex models, a combination of both approaches is often the best option. Wire armatures provide the necessary support to maintain the overall form, while plastic clays like Milliput and DAS offer the flexibility to create intricate details.

When deciding between wire and plastic clays, consider the following factors:

Project complexity: For simpler models, a wire armature alone might be sufficient. For more complex sculptures, a combination of armature and plastic clay is ideal. Details required: If high levels of detail are needed, plastic clays provide better support and texture control. Wire armatures alone may result in less detailed work. End-use of the model: If the model will be painted or displayed in a public setting, plastic clays can offer better long-term durability and stability. Artist preference: Some artists might have a preference for working with wire due to its rigidity, while others might prefer the flexibility and ease of use provided by plastic clays.

Regardless of the choice, both wire armatures and plastic clays serve as essential tools in the sculptor's toolbox, each offering unique advantages that can enhance the final product. Whether you are an experienced artist or a beginner looking to refine your skills, understanding the properties and applications of these materials is key to achieving the best results in your projects.
