Brim In 3D printing, a brim is a type of print adhesion helper that consists of a flat layer of material printed around the base of a model. Unlike a raft, which is printed under the model, a brim only touches the outer edges of the first layer and does not extend beneath the model itself. It is commonly used to improve bed adhesion, reduce warping, and stabilize the print during the early stages of printing. Brims are particularly useful for models with small contact points on the build plate, as they increase the surface area holding the print to the bed. Once the print is complete, the brim can be easily removed during post-processing. |
