How does Fused Deposition Modeling create objects?

Fused Deposition Modeling (FDM) creates objects by extruding molten material through a nozzle layer by layer. This process begins with a thermoplastic filament which is heated until it becomes malleable, allowing it to be pushed through a nozzle. The printer moves the nozzle in a precise pattern based on the digital model, depositing the molten material onto a build platform. As each layer is applied, it cools and solidifies, bonding with the previously laid layers. This layering approach continues until the entire object is formed.

The reason this method is effective for creating detailed and complex geometries is due to its precise control over material deposition and the ability to construct shapes that are often difficult or impossible to achieve with traditional manufacturing methods. This technique is widely used in various applications from prototyping to production of functional parts.
