1. A method of three-dimensional (3D) printing, comprising:
depositing a material onto a receiver device, via a plurality of material deposition units, to form a printed layer on the receiver device, the printed layer including a particulate material and a liquid vehicle;
transferring the printed layer from the receiver device to a material removing unit;
gradually removing at least a portion of the liquid vehicle from the printed layer via the material removing unit comprising a plurality of extraction units;
applying, via at least one extraction unit, back pressure to release the printed layer from the at least one extraction unit to transfer the printed layer from the material removing unit to a delivery system; and
transferring, via the delivery system, the printed layer from the material removal system to a build platform.
