METHOD AND SYSTEM FOR MONITORING AMOUNT OF SUPPLY MATERIAL IN ADDITIVE MANUFACTURING

Abstract:

A method of monitoring an amount of building material in a cartridge that supplies the material to an additive manufacturing system, comprises introducing gas into the cartridge and measuring the pressure within the cartridge. When the pressure reaches a predetermined level, the amount of building material in the cartridge is determined based on a volume of gas introduced into the cartridge or based on a proxy of the volume.
