lankasyöttönopeus

Lankasyöttönopeus refers to the speed at which filament is fed into a 3D printer's extruder. This parameter is crucial for controlling the amount of molten plastic deposited onto the print bed, directly impacting print quality, speed, and material usage.

In fused deposition modeling (FDM) 3D printing, the filament is typically a thermoplastic material wound onto a spool. The extruder mechanism, often a geared motor, grips the filament and pushes it through a heated nozzle. The lankasyöttönopeus determines how quickly this motor turns, and consequently, how much filament passes through the nozzle per unit of time.

A higher lankasyöttönopeus generally leads to faster print speeds, as more material is extruded in a given period. However, if set too high, it can result in over-extrusion, where too much plastic is deposited, leading to blobs, stringing, and poor layer adhesion. Conversely, a lower lankasyöttönopeus can prevent over-extrusion and improve detail, but it will significantly slow down the printing process.

This setting is often expressed in millimeters per second (mm/s) or as a percentage of the maximum possible feed rate. It is typically adjusted within the 3D printer's slicer software, which converts the 3D model into machine instructions. Fine-tuning the lankasyöttönopeus is a key aspect of the calibration process for any 3D printer and is dependent on factors such as the nozzle diameter, filament diameter, printing temperature, and desired print resolution. Material properties also play a role, with some filaments requiring different feed rates than others.
