Which parameter can directly affect print quality in FDM printing?

Print speed is a crucial parameter that can directly affect the print quality in Fused Deposition Modeling (FDM) printing. It determines how quickly the printer lays down the filament, impacting the detail and finish of the printed object. If the print speed is too high, there may be insufficient time for layers to extrude properly, leading to poor adhesion between the layers, inaccuracies in detail, and potential defects such as stringing or under-extrusion. Conversely, a slower print speed allows for better layer cohesion and more precise detail, though it can increase the total print time.

The color of the filament, while it may influence the aesthetic qualities of the print, does not inherently affect the mechanical properties or the overall quality in terms of layer adhesion or structural integrity. The volume of the printer is related to its capacity to handle the dimensions of a model rather than the quality of the print itself. The brand of the printer can indicate quality and reliability, but it does not directly influence the print quality parameters like speed, flow rate, or temperature settings that are crucial during the printing process. Therefore, managing print speed is key to achieving optimal print quality in FDM printing.
