How does reducing print speed affect FDM printing?

Reducing print speed in Fused Deposition Modeling (FDM) can lead to improved detail and layer adhesion for several reasons. When the print speed is reduced, the extruder has more time to carefully lay down each layer of filament. This can enhance the resolution of the details in the print since the nozzle can more accurately place the material, resulting in sharper features and finer details.

Additionally, slower printing speeds allow for better layer adhesion. When the filament is extruded at a slower rate, it has more time to fuse into the layer below; this enhances the bond between layers, leading to a stronger and more durable printed object. The reduction in speed helps the material maintain its proper temperature for a longer period as well, promoting better adhesion without risking issues like warping or separation between layers.

In contrast, higher print speeds can sometimes lead to compromised quality, where the filament does not adhere properly, resulting in weaker points in the structure or loss of detail in intricate designs.
