Abstract

An apparatus for producing a three-dimensional part by successive layer-by-layer solidification of a solidifiable material, which is solidified at locations corresponding to the cross section of the part is described. The apparatus has a machine housing and a building space provided in the machine housing. An interchangeable container forms a delimiting frame for the material within the building space. The container has a work piece platform. The work piece platform is supported on a supporting device during operation of the apparatus. Preferably, the interchangeable container has a rear side wall with a recess extending vertically, and the supporting device engages the work piece platform through the recess.
