There are three types of adhesion, skirt, brim and raft. Brim adds a single layer flat area around the base of the print model which prevents warping. This is the default adhesion type. The brim is connected to the model making the bottom surface area bigger. It not only increases the adhesion of the model to the build plate, but it also prevents the corners of the model from curling. Materials with high potential for shrinking such as ABS will benefit from a brim. Models with a large base or a thin bottom should also use a brim adhesion. As raft adhesion adds a thick grid with a roof between the model and the build plate. This is typically used when the bottom surface of a model is not completely flat or has little area to adhere to the build plate. A skirt is a line printed around the model on the first layer. It is typically not used to help the print adhere but used to prime the nozzle and check for bed leveling.

Dual colour prints refer to a technique that can print multiple colour<ins>s</ins> on one model using one nozzle head. This is achieved by switching the filament during the printing process. Dual extrusion refers to printing a model with 2 nozzle<ins>s</ins> to extrude two different filament<ins>s</ins>. This will allow for mixing colours, gradients, or patterns. It can also print models using two different material<ins>s</ins> for different parts of the object for complex geometries that would otherwise be difficult to achieve.
