Which aspect should be avoided to enhance print quality in FDM?

Reducing the flow rate too significantly can negatively impact print quality in Fused Deposition Modeling (FDM). The flow rate dictates the amount of material extruded from the nozzle during printing, and if it is set too low, the printer may not deposit enough filament to build up the desired layer thickness. This can result in issues like under-extrusion, where gaps and weak spots form in the print, leading to a compromised finished product. Additionally, low flow rates can affect layer adhesion, making it difficult for the print to maintain structural integrity and achieve the expected detail.

In contrast, maintaining consistent speed, calibrating the printer regularly, and utilizing quality filament are all practices that contribute positively to print quality. Consistent speed ensures that the filament is deposited in a uniform manner, while regular calibration helps maintain accuracy in dimensions and layer placement. Using quality filament ensures that the material consistently melts and extrudes well, which is critical for achieving the desired print characteristics. Thus, avoiding excessive reductions in flow rate is essential for maintaining high print quality in FDM.
