− | The print speed is another one of those obvious parameters that will affect print times. However, the ways in which the print speed will affect the final print are not always obvious. If the print speed is too high, the printer might not be able to dispense enough material through its nozzle per unit of time to fill the desired volume with the required amount of material. This can lead to bad adhesion between layers or even a complete lack of adhesion to layers. The ratio of layer height to layer speed (i.e.: material outflow through the nozzle) should therefore always be considered when FDM printing (the exact subject though being more of an intermediate subject). When making parts that will bear loads, print speeds are increasingly important as layer adhesion becomes an important factor in the strength of the final part, so much so that parts may be annealed (uniformly re-heated through a controlled process) to obtain better properties across layers.<ref>Agnieszka Szust, Grzegorz Adamski, ''Using thermal annealing and salt remelting to increase tensile properties of 3D FDM prints'', Engineering Failure Analysis, Volume 132, 2022, 105932, ISSN 1350-6307, <nowiki>https://doi.org/10.1016/j.engfailanal.2021.105932</nowiki>.</ref> | + | The print speed is another one of those obvious parameters that will affect print times. Since the beginner slicing methods do not include modifications to print speed, going over this parameter was considered out of the scope of beginner knowledge and such print speed will be discussed in the intermediate page. |
