With the use of non-conventional materials, such as nylon, or when printing some FDM / FFF parts having a small base or a complex design, adhesion problems of the filament with the base may occur both at the beginning and during 3D printing. The first thing to check is the leveling of the base and the temperature of the base is correct for that type of filament. If, however, the setback still persists, the error can be remedied by 3 different methods of adherence to the base: brim, raft or skirt. Its activation through the chosen print program (Cura, Simplify3D, etc) will be in the section of "adhesion platform".

Here's what these three parameters are all about:

SKIRT

This process is responsible for the preparation of the copy of the contour of the piece to be printed, before the piece itself is printed. This ensures the purging of the extruder before beginning to manufacture the part and leveling the base, avoiding errors at the beginning. You can set the number of contour turns you make, the separation distance to the piece, and the height to which it must be made. If the contour is created with the height of the piece, a wall is created that protects it from drafts, which helps the 3D printing of materials sensitive to this, such as ABS.

BRIM

The Brim uses the same process as the skirt, but in direct contact with the workpiece. This method is ideal for small or narrow base parts, such as a chair or a tower. It is also recommended to use 3D prints of parts that can peel corners or contain narrow parts, such as pinions and gears. With the use of 1-2 layers of height adhesion is achieved to avoid the problem.The only drawback of this method is the difficulty of removing it after 3D printing if there is no post-processed tool, such as Modifi3D.

RAFT

This is best for materials that are difficult to bond to the base. This system creates a horizontal lattice between the base of the 3D printer and the part. As this lattice has more contact area with the base than the piece itself, it favors adhesion and avoids leveling problems (when the attachment is small). Regarding the latter, in some 3D printers that have a large base and whose exact leveling is very difficult to achieve, it is advisable to always use the raft. Unlike the brim, the raft holder, it is easy to remove and almost no debris none.

With the processes mentioned above, any user can make 3D prints of all types and with almost any material without any problem or complication, such as warping.

      Como traducirían al español Raft y Brim? Gracias

      Hola Sibila. Se puede traducir raft como falta y brim como borde, aunque en el contexto de la impresión 3D se suelen utilizar los términos en inglés.

      ¿cómo puedo solucionar el problema que tengo? Al crerar un muñeco en vertical, al llegar a las manos... le ponfo el RAFT para que no "quede en el aire" pero no es suficiente y el extrusor cada vez que da una capa mueve el soporte del raft y el resultado de los brazos es espantoso. Gracias

        Eso es soporte, no raft. Debes ajustar mejor los parámetros de soporte como densidad o tipo. Además puedes en el propio diseño de la pieza hacer uniones para rigidizar la misma y así evitar esa inestabilidad.

      hola, buenas a todos! Mi problema es el siguiente: quiero empezar a incurrir en el mundo de las litofanías, y como saben hay q imprimirlas en vertical para un mejor acabado. No logro q la misma quede pegada a la base durante todo el proceso, se despega de la balsa y borde sin importar que parámetros altere, o sea, el borde o balsa siguen adheridos a la cama, pero el modelo se despega de la balsa/ borde. Hay alguna manera de solidificar la union del modelo stl con la balsa?

        Tengo, el mismo problema. Hay que modificar el Raft Aip Gap (espacio entre la litofanía y la balsa). Ponélo en 0,1. después hay que tener cuidado, al retirar la balsa. O anda probando, el grosor del espacio.

      Hola ..el raft tiene algún grosor mínimo?,,,, en el Cura el grosor esta dado por Raft top layer thickness, Raft middle thickness y Raft base thickness supongo q modificando cualquiera de estos valores modifico el grosor..
