1. A method for producing a part using a deposition technique in layers by building a layered composite containing the part from particulate matter comprised of particles of a prescribed particle size, the method comprising steps of:

  • depositing the particulate matter layer-by-layer to form successive layers of a porous bulk in a build location, andselectively apportioning a treatment agent in a predefined subarea of the layer prior to deposition of a subsequent layer, wherein the treatment agent is apportioned in a free-flowing state for setting up a bonding process, in which the particles in the predefined subarea bond firmly to one another, through a binder contained either in the particulate matter or deposited thereon, in the presence of an initiator,moving the layered composite to a different location; and

    bonding the particulate matter in the different location;

    whereby the building of the layered composite is done in the absence of an initiator, and the bonding process is executed only after completion of the layered composite, through addition of such initiator.
