Material settings

Build volume temperature

The temperature of the environment during printing. This setting is only available to printers that are closed off during printing and have active temperature control, like the Ultimaker S5 & Air manager.

Default printing temperature

This is the printing temperature of the materials as found in the materials panel, without any extrusion rate corrections applied to it.

Printing temperature

This refers to the temperature of the nozzle while printing, including the adapted extrusion rate. Each printing profile has a slightly different printing temperature to create the best print result.

Printing temperature initial layer

This is the printing temperature of the layer that adheres to the build plate. Printing at a slightly warmer temperature increases the adhesion between the build plate and the model.

Initial printing temperature

This setting is only used in dual extrusion machines. When switching nozzles, the inactive nozzle cools down to the standby temperature. During the warm up, the nozzle is allowed to start printing when this temperature is reached. The temperature is slightly lower than the printing temperature since the filament already obtained heat from the nozzle for a longer period of time.

Final printing temperature

This setting is only used in dual extrusion machines. When switching nozzles, the inactive nozzle has to cool down. Just before the nozzle switch, the nozzle is allowed to cool down to this temperature while continuing to extrude. This prevents excessive oozing when in standby mode.


Extrusion cool down speed modifier

The temperature change here indicates how much faster the nozzle cools down when extruding. The extra heat lost by extruding hot filament is compensated by this value.

Build plate temperature

This setting defines the heated bed temperature during the printing process. Each material has an ideal build plate temperature, which is set here. When printing with two different materials, the temperature will be an average of the two. Changing this value is uncommon.

Build plate temperature initial layer

This is the temperature of the build plate when printing the first layer. A slightly warmer build plate during the layer reduces the chance of warping.

Scaling factor shrinkage compensation

This setting take into account the dimensions your 3D model will have after printing and cooling of the 3D printed material. This allows dimensions to come even closer to the expected final result. As materials have different shrinkage factors, the values here depend on the material loaded in your 3D printer.



The flow is the amount of material that needs to be extruded over a specific amount of time and is based on the filament diameter and print speed. The flow is always set to 100%, which means that the extruded amount of filament will match the calculated amount. This setting is not usually changed, as the calculation is done automatically, but it can be useful when printing with experimental materials.

It is not advised to increase the flow to compensate for under extrusion. This will only work temporarily and won’t solve the underlying cause.

Standby temperature

This refers to the temperature of the nozzle when it is in standby mode, while the active nozzle is printing. The standby temperature is low enough to protect the filament from degrading or clogging, but is high enough to quickly continue printing.
