In FDM 3D printing, one of the most common problems that users face is the bending and cracking on the models while printing. Printed parts with such deformations can still be used. During the printing process, filament material has to be cooled after it leaves the nozzle. If the cooling time for the filament is too short or too long there can be deformations in the printed part such as bending or cracking.
