Mostly because of the moving of these articles to subdirectories. However while doing this I found a dozen or so links that were broken anyway. That must've been broken in a release too, even.

For some shapes, modifying the outside shape of the mould is not enough to make it print properly. It'll still need support. You can achieve a similar effect by enabling [Conical Support](support_conical_enabled.md).

The prime tower brim is an additional brim, similar to the brim option in the [Build Plate Adhesion Type](adhesion_type.md). This brim can be enabled and disabled separately from the ordinary adhesion. When activated, an additional brim will be printed around the prime tower.

![The adhesion is set to skirt, but there is still a brim around the prime tower](../images/prime_tower_brim_enable.png)

Enabling the prime tower brim will give the prime tower more surface area to connect to the build plate. Because the prime tower can get pretty tall and slim, it may topple over for very tall prints. This prime tower brim is meant to prevent that at a small cost of printing time, material and space on the build plate.

The prime tower brim will get the width defined in the [Brim Width](brim_width.md) setting. If the Build Plate Adhesion Type is set to Brim, this setting effectively doubles the width of the brim around the prime tower.

If the model has both shallow surfaces and steep surfaces at the same height, the layer thickness is taken to be the smaller of the layer thicknesses. This sometimes makes the layer height unnecessarily small because there is a horizontal surface next to it. This can be seen in the screenshot above as well halfway the height of the silo on the left.

Adaptive Layers is heavily constrained in order to improve printing quality. The layer height is not allowed to deviate more than a specified [Maximum Variation](adaptive_layer_height_variation.md) from the original [Layer Height](layer_height.md) setting. Between two adjacent layers the difference in layer height may not be more than a certain [Step Size](adaptive_layer_height_variation_step.md). This causes the layer thickness to gradually transition instead of suddenly cutting it in half from one layer to the next.

This causes the layer thickness to gradually transition instead of suddenly cutting it in half from one layer to the next.

Adaptive Layers can considerably reduce the printing time without suffering a loss in print quality, or even while improving quality in some cases. The effect of adjusting the layer thickness is immense. In most cases, the printing time will be greatly reduced, due to using thicker layers where the model is vertical. The topography effect is also reduced because the layers are spaced closer together horizontally.

However this feature can introduce a number of problems as well.
* With changing the layer height, some other settings typically need to be adjusted as well, such as the nozzle temperature. Adaptive Layers will not automatically adjust those as well. This can make the print sub-optimal for e.g. overhangs that would fare better at a lower printing temperature.
* If the layer height is changed over the entire layer for a small feature somewhere in a small part of the layer, banding will be visible in the rest of the layer.
* Vertical distances are unintentionally adjusted with this as well. This may have a negative effect on the print quality. For instance, the [Top/Bottom Thickness](top_bottom_thickness.md) will typically become lower because Cura will hold the [Top Layers](top_layers.md) setting as truth, and the layers become thinner. This can cause pillowing. Affected settings that may no longer be correct include:
* [Top Thickness](top_thickness.md)
* [Bottom Thickness](bottom_thickness.md)
* [Maximum Skin Angle for Expansion](max_skin_angle_for_expansion.md)
* [Gradual Infill Step Height](gradual_infill_step_height.md)

For example, with a normal layer height of 0.15mm and the variation set to 0.1mm, Adaptive Layers may produce layers with a thickness between 0.05mm and 0.25mm.

This setting controls the fan speed during bridging of both the walls and skin. This fan speed overrides the normal [fan speed](../cooling/cool_fan_speed.md) that would otherwise be used.

Normally you'll want the fan speed to be turned up as high as possible during bridging. The fan speed will need to be higher than for the rest of the print. This prevents sagging, as the material can solidify more quickly.

This setting controls the fan speed during the printing of the skin of the second layer above a bridge. This fan speed overrides the normal [fan speed](../cooling/cool_fan_speed.md) that would otherwise be used.

If the [fan speed](bridge_fan_speed.md) was increased for the first bridge layer, you'll most likely also want to increase the fan speed for the second layer. This cools the material more quickly which causes it to lean less on the previous layer. There are really no significant downsides. In theory, increasing the fan speed too much would cause the layers to bond too weakly, compromising strength. However the layers already bond very weakly during a bridge so there is very little strength that can be gained from reducing the fan speed.

Normally Cura will use a fairly rudimentary bridging technique. Cura will detect overhanging areas of skin that are supported on multiple sides. The [direction of those skin lines](skin_angles.md) is adjusted to bridge those areas automatically. This ensures that the greatest possible part of the overhanging area is supported on multiple sides and improves print quality.

For materials that require the fan to be turned on and turned up high (such as PLA), it is generally better to print bridges very slow. This allows the fans to blow a lot of air over the material, which causes them to solidify very quickly. The material doesn't get as much chance to sag then. This is less effective for materials that don't need the fan to be spinning so fast or printers that don't have a very powerful fan.

However printing slow will also create a large change in the rate at which material needs to be extruded from the nozzle opening. While the print head can generally slow down very quickly, the material in the nozzle chamber will remain flowing for a while longer due to latent pressure inside the nozzle chamber. So as the print head slows down, there will be some overextrusion in the beginning of the bridging line. As the print head speeds up again afterwards, there will be some underextrusion. Keeping the speed closer to the normal [printing speed of the top/bottom](speed_topbottom.md) prevents that from happening.

In general it is better to print the bridging skin lines very slowly with materials that print at cold temperatures, such as PLA. It is better to print the bridging skin lines around the same speed as the ordinary top/bottom speed when printing with high-temperature materials such as polycarbonate.
