Build plate adhesion is one of the most important things when 3D printing. There are obviously many things that affect build plate adhesion. Most of them are specific to the 3D printer you use as well as the material you are printing. But regardless of those things, you can generally improve build plate adhesion using your slicing software.
There are generally 3 options skirt, brim, and raft. They are used for different purposes. For example brim and raft are very useful when your model has a lot of tiny features on its base. But I go in more detail in the video.
Those options are just perfect for improving the reliability of your prints. There is nothing worse than your model becoming loose halfway through the print.
