How does temperature affect the FDM process?

In the context of Fused Deposition Modelling (FDM), temperature plays a critical role in the quality of the printed parts. When the temperature fluctuates or is not properly controlled, it can lead to inconsistent melting of the filament, which in turn affects the adhesion between layers. Poor bonding between layers can result in weakened parts that may be prone to delamination or structural failure during use.

Optimizing temperature settings is essential for ensuring that the thermoplastic material is extruded at the right viscosity and can adequately bond with the previous layer before it solidifies. If the temperature is too low, the material might not flow appropriately, leading to a weak bond. Conversely, if the temperature is too high, it can cause overheating, which may also negatively affect layer adhesion. Therefore, maintaining a stable and appropriate temperature is key to achieving high-quality prints with good layer bonding and overall structural integrity.
