<p>When should I use a raft, and when should I use a brim? What advantages does each have over the other?</p>

Instead of printing directly on the build surface, parts are built on top of it. You remove and dispose of a raft post-print. The raft is larger than the part and so has more adhesion. Rafts are primarily used with ABS to help with bed adhesion. Rafts are also used to help stabilize models with small footprints (e.g. a pole), or to create a strong foundation on which to build the upper layers of a model. If your only concern is bed adhesion it is better to use a brim.</p>\n<p>A brim is attached to a model and extends outward. Brims typically have several outlines and may be a few layers tall. Brims are often used to stabilize small parts of a model, such as legs of a table, because brims help these areas stay connected to the print bed.</p>\n<h3>TL;DR</h3>\n<p>The brim is only around a model and attached to its first layer, a raft is also under it.</p>\n'}, {'answer_id': 16205, 'author': 'flounder', 'author_id': 10900, 'author_profile': 'https://3dprinting.stackexchange.com/users/10900', 'pm_score': 0, 'selected': False, 'text': '<p>I have been favoring brims recently; I am tired of the rafts becoming an integral part of my print, impossible to remove.</p>\n'}]
