Using brims is a good way to check the calibration and first-layer adhesion before starting the actual print. It uses less material and doesn’t touch the model. If you’re considering a brim to check that the print bed is correctly leveled, that the filament is being extruded, or other print settings but don’t need actual first-layer adhesion aid, you’d be better off using a skirt. The bigger it is, the more lines the brim should have so it has enough strength to pull on the part. When you want to use a brim to prevent warping, the line count defining the brim’s width will depend on the surface area of your base layer. Similar to the way the upper parts of the print may try to pull the base up, the brim will pull it down, keeping it in place. Using a brim helps with warping because it acts like a net that forces the bottom of the print to stay attached to the bed. Large flat-bottomed models, for instance, might warp during printing. In addition to materials, the actual design of the model can lead to this issue. Low-quality filaments are also more likely to warp. Warping can happen with many filament materials, although some are more prone to warping than others. When warping becomes apparent, you may have already invested a lot of time and material on the print. This is something that happens as the print advances. Warping is a 3D printing issue that causes the first layers of the print to shrink due to the pull of layers further up.
