Abstract: A material mixing cartridge for a dispensing system comprises a dispensing chamber, with a material dispensing outlet and a dispensing actuator for dispensing material through the material dispensing outlet. The mixing cartridge further comprises at least two material compartments for receiving material to be mixed, and at least one material transfer channel which is adapted for material transfer between the at least two material compartments and the dispensing chamber The mixing cartridge further comprises at least one valve arranged to regulate material flow between a material compartment and the dispensing chamber via the at least one material transfer channel.

Abstract: A material cartridge arrangement (100, 101) for a dispensing system, comprising a material cartridge (2) having a first end (2a), an opposing second end (2b) and an ink material channel (5) extending between the first and second ends in the material cartridge (2), the ink material channel (5) being bounded by an ink material channel wall/walls (9) extending between the first (2a) and second ends (2b). An ink material pressurising device (3) is arranged to cause ink material hold in the ink material channel (5) to flow in a direction from said first end (2a) towards said second end (2b) and through an ink material outlet. At least one temperature sensing element (16) is arranged at a position along the direction of extension of the ink material channel (5) and arranged to measure a temperature at the ink material channel wall (9).
