Which technique directly contributes to the creation of three-dimensional objects through layering?

Fused deposition modelling (FDM) is a popular technique for creating three-dimensional objects through a layering process. It works by extruding thermoplastic materials layer by layer to build up the desired shape of the object. This additive manufacturing process allows for a high degree of customization and complexity in design, as it can produce intricate geometries that are often difficult to achieve using traditional subtractive manufacturing methods.

FDM is particularly favored for its efficiency and cost-effectiveness, making it accessible for both prototyping and final product manufacturing. It is widely used in various industries, from automotive to healthcare, for creating prototypes, functional parts, and even end-use products. The ability to manipulate digital models into tangible objects through this layering technique is what sets it apart as a direct contributor to 3D object creation.

Techniques like solid modelling and stereolithography also play significant roles in 3D design and production. However, while solid modelling refers to the creation of a digital representation of an object in 3D space, stereolithography is a specific 3D printing method that uses a UV laser to cure resin layer by layer. Mockup creation involves building a physical or digital representation but does not involve the additive layering process that FDM utilizes to construct objects
