1. A system for three-dimensional printing of at least one three-dimensional object comprising:
- a platform configured to accommodate the at least one three-dimensional object during the printing;
an energy source configured to generate an energy beam that transforms a pre-transformed material to a transformed material to print the at least one three-dimensional object;
a material remover that is laterally movable in a first direction, which material remover comprises;
an internal compartment configured to, at least during printing, (i) accommodate a pre-transformed material and (ii) facilitate equilibration of an attractive force, which equilibration is along a second direction that is different from the first direction, which attractive force is generated by an attractive force source operatively coupled to the internal compartment; and
an opening configured to facilitate entry of the pre-transformed material into the it compartment by being attracted by the attractive force, which opening is operatively coupled to the internal compartment,wherein at least during printing;
(a) the internal compartment is configured to move laterally in the first direction, (b) the internal compartment is disposed above the at least one three-dimensional object, (c) the opening is configured to facilitate the entry of the pre-transformed material into the internal compartment by being attracted by the attractive force in a direction comprising an upwards component, or (d) any combination of (a), (b), and (c), wherein upwards and above are along a direction oriented vertically towards the energy beam.
