Hot chamber

The hot chamber is a system integrated into the printer that allows the temperature inside the build volume to be increased by a flow of heated air. This temperature control system is analogous to those used to regulate the temperature of the nozzle or print bed.

The use of the hot chamber is mainly intended for printing large objects or with materials that tend to delaminate and shrink during the printing process. We recommend the use of the hot chamber for the following materials:

  • ABS:  Recommended hot chamber temperature: 50-60°C.
  • PA + CARBON FIBER:  Recommended hot chamber temperature: 50-60°C.
  • PMMA:  Recommended hot chamber temperature: 60°C.

In general, using the hot chamber makes sense for materials with an extrusion temperature above 250°C and that are prone to delamination.

IMPORTANT: Using the hot chamber in unsuitable situations, such as with materials such as PLA, can cause problems rather than solve them. Therefore, it is crucial to select the use of hot chamber only when it is appropriate for the material and object you are printing.

You can set the target temperature value of the hot chamber in several ways:

  • MANUALLY: You can adjust the temperature from the printer’s monitoring screen via the user interface.
  • SLICING SOFTWARE: Some slicing software allows you to set the temperature of the hot runner using a specific temperature identifier, such as T5.

IMPORTANT: You must avoid activating the “wait for the temperature to stabilize before starting” option for the hot chamber control.

In addition, it should be considered that in any closed printer with a heated print bed, the build volume can reach significantly higher temperatures than in the external environment. Therefore, it is necessary to take this aspect into account when using the hot chamber to avoid problems related to excessive temperatures.
