fill density
The filling density determines the amount of plastic the model will have inside.A higher infill density means more plastic is melted inside the model, which will result in a stronger object.
This is going to be one of the settings you'll change the most, depending on the model you print, as some models will need more (or less) infills than others.
Recommended fill density: 20% for models with a visual purpose, a higher percentage can be used for more resistant parts.
Fill line distance
Instead of a fill percentage, it is also possible to set the line spacing. This measurement expressed in millimeters will determine the distance between fill lines, which would be the same as changing the fill density.
Recommendation: keep this option disabled as it might confuse you (you don't need it)
Fill pattern
Cura allows you to choose the type of printed fill pattern, which is useful in some specific use cases. For example:
- 2D fills for daily prints.
- Quick 2D Fillers: They are used in fast but fragile models.
- 3D fillings: It is used to make the model stronger.
- 3D concentric fillings: Used for flexible materials.
The following pattern options are available:
- Rack: strong 2D padding
- Lines: fast 2d fill
- Triangles: strong 2D padding
- Tri-hexagon: strong 2D padding
- Cubic: strong 3D padding
- Cubic Subdivision: Strong 3D infill (this saves material compared to Cubic)
- Octet: strong 3D padding
- Bitruncated Cubic: strong 3D padding
- Concentric: flexible 3D padding
- Zig Zag: continuous diagonal grid shape
- Cross: flexible 3D padding
- 3D cross : flexible 3D padding
- gyroid : padding with greater strength for the least weight.
- Lightning: New fill pattern in the latest versions of Cura. It seeks to minimize the padding, resting only on the upper part of the model.
Fill Line Directions
Fill lines are printed at a 45° angle to gain speed without losing quality. Still lines can be printed in a different direction by setting the degrees to 0° (for vertical) and 90° (for horizontal). For example: [0,90].
Fill XY Offset
fill patterns They start from a center. But the pattern can be shifted to any other side (off-center) can be done with an X or Y offset. A positive value moves it UP and RIGHT, and a negative value moves it DOWN or LEFT. This does not work for concentric fills.
Fill Overlap Percentage
It refers to the percentage of bond between the filling and the walls.. A higher value may result in a better bond between the infill and the walls. However, too high a value could cause over-extrusion and make the infill visible from the outside.
Recommended fill overlap percentage: 30.0 %
Fill Pass Distance
This setting tells the printer to stop extruding before it starts printing the walls of the infill. The printer will still extrude some filament due to the pressure in the nozzle, but stopping extrusion early will reduce over-extrusion.
Infill layer thickness
This function is used to change the thickness of the fill lines.Thicker layers of infill can be printed to reduce printing times.
When you change this setting, make sure it is a multiple of layer height; otherwise Cura will round it to a multiple of the layer height.
You can then, for example, print with an infill thickness of 0.2 mm while the layer height is 0.1 mm. The printer will then first print the walls in two layers and then print a thicker infill layer.
Necessary padding steps
This function reduces the infill percentage at the bottom of the model, leaving the full percentage in the upper layers..
Si con un porcetaje de relleno de 20% se seleccionan «2 pasos» entonces dejará un 10% en la capas inferiores y luego aumentará al 20% en las ultimas capas.
Cada «paso de relleno necesario» divide el porcentaje de relleno por dos.
In the image above on the right you can see how the filling in the lower layers was reduced by 10% and in the last layers it continues with the 20% selected.
Gradual fill step height
This setting is used to choose the height to which the padding should be reduced from the top layers.
Para que esta función aparezca en los ajustes de Cura debes seleccionarla y usar la función «padding steps requireds» explicados más arriba.
The top layers will close easily, without having to add additional filling.
Fill before the walls
With this setting enabled, the infill will be printed before the walls. This results in better overhangs because the walls will adhere to the already printed infill.
Printing in this order can also have a disadvantage.
If the infill prints before the walls, There is a possibility that the filling will be visible through the walls, which will result in a rougher surface finish.
Recommendation: Disable this option, as your fill may become visible from the outside walls. If this is a problem you were having and didn't know how to fix it, here is the answer.
Minimum fill area
This setting allows smaller parts of a model to be printed as perimeters. (and not as filler).
El siguiente modelo es de una solera de auto (o parasol). La orientación no es la adecuada, pero para fines educativos «hagamos de cuenta que así lo queremos imprimir»
La partes de abajo serían las más finas y más faciles de quebrarse. Con esta configuración se puede elegir el «minimum fill area» con la que Cura pondría el relleno por fuera de ese «mínimo» elegido.
The minimal fill area strengthens the clips of this coupling making it completely rimmed.
Normalmente (para lograr este efecto), lo que más se usa son los «ajustes por modelo» en la barra de menú vertical de la izquierda, colocando un 100% de relleno para las zonas selecionadas.
