1. A machine for additive manufacturing by sintering or melting powder using an energy beam acting on a powder layer in a working zone, comprising:
a device for layering said powder:
storing means for storing the powder,distributing means for distributing the powder that are able to travel over the working zone in order to distribute the powder in a layer having a final thickness suitable for additive manufacturing,feeding means that are able to transfer the powder from the storage means to the distributing means,metering means that are able to control the quantity of powder transferred from the storage means to the distributing means, wherein:
the storage means are positioned higher than the working zone,the feeding means utilize gravity,the feeding means and the metering means are able to move with the distributing means, and two separate working zones, two separate working trays that are able to move independently of one another, wherein:
each of the two separate working trays is associated with only one of the two separate working zones, andthe device for layering said powder is common to both working zones.
