Interchangeable container
First Claim
1. An interchangeable container for a system for building a mold body by forming superimposed layers of granular material, the granular material locally and selectively hardened layer by layer, the container comprising:
- at least one pair of side walls;
a bottom structure that is displaceable in the interior of the container in a direction in parallel with said side walls; and
at least one spindle drive comprisinga vertical screw spindle which is rotatably mounted in a container side of the container, anda spindle screw nut on which the bottom structure is supported, such that the bottom structure can be lowered step by step in the interior of the container by means of the spindle drive.
