Brim/Skirt/Raft

Brim

A brim is a single layer flat area around the base of your model. Its purpose is to keep the edges of your print down and make the contact area between your print and the build plate bigger.

• The bigger surface area allows your print to stick better to the build plate. This is useful for pretty much any print larger than a few centimetres.

• This brim will also keep the edges of your print down. Materials that shrink a lot when cooling down (like ABS) tend to warp a lot while printing. Having a brim with sufficient width can keep the corners in place, preventing this warping.

Brim Line Count

Controls how many perimeters are being drawn around the base of your print.

More brim lines will improve adhesion to the build plate, by increasing the surface area of your print. However, it will reduce the effective print area.
