How can the use of rafts assist in 3D printing?

The use of rafts in 3D printing significantly enhances the adhesion of models to the build plate. A raft is an additional layer that is printed beneath the model, creating a larger surface area for the initial layers. This increased surface area helps to secure the model more effectively to the build plate, reducing the likelihood of warping or shifting during the printing process. Strong adhesion is particularly crucial for materials that have a tendency to warp as they cool, as it ensures the model remains in place throughout the entire print job.

Additionally, because the raft acts as a buffer between the build plate and the model, it can also help to compensate for imperfections in the build surface, further improving the quality of the printed part. This makes rafts a valuable tool in achieving successful prints, particularly when working with various materials and complex geometries.
