The skirt is a printed outline that surrounds all the models on the print bed. It is created before the actual printing of the models and serves primarily to ensure a stable flow of filament through the nozzle.
The purpose of the skirt is to help prime and prepare the extruder for the actual printing process. By printing this initial outline, it helps to purge any air bubbles or inconsistencies in the filament, ensuring a smooth and consistent flow of material when printing the models.
Brim is a feature in 3D printing that creates a thin, flat extension around the base of the printed object. It is typically printed as a series of connected lines or loops, extending horizontally from the bottom layer of the model.
The primary purpose of using a brim is to enhance bed adhesion during the printing process. By increasing the contact area between the model and the build plate, the brim provides better stability and reduces the likelihood of warping, lifting, or detachment.
