Rafts, Skirts, and Brims Tutorial


Rafts, Skirts, and Brims Tutorial | Simplify3D

A Raft is a horizontal latticework of filament that is located underneath your part.  Your 3D printed part will be printed on top of this raft, instead of directly on the build platform surface.

A skirt is an outline that surrounds your part but does not touch the part.  The skirt is extruded on the print bed before starting to print your model. Skirts serve a useful purpose because they help prime your extruder and establish a smooth flow of filament.

A Brim is a special type of skirt that is actually attached to the edges of your model. Typically, the brim is printed with a increased number of outlines to create a large ring around your part, similar to the brim of a hat. Brims are often used to hold down the edges of your part, which can prevent warping and help with bed adhesion
