First Claim
Patent Images
1. A build container for a device for producing three-dimensional objects by layering, comprising:
- a build space on a building platform having a rectangular shape defining short sides and long sides of the build container, wherein the build space is adjustable in a height and is within the build container;
wherein during a displacement of the building platform to adjust the height of the build space, a kinetic friction between constructed layers and at least two side walls is reduced or essentially avoided, the building platform and the at least two side walls being moved at the same speed, wherein the build container includes a drive engagement on each of the short sides for attaching to a Z-axis drive unit, and wherein the only movement of the build platform during building of the three-dimensional objects is a vertical movement.

22. A method for producing three-dimensional objects by layering comprising the steps of:
- constructing layers of a three-dimensional object with a coater for applying particulate material;
wherein between a process of constructing two layers, a build platform is displaced to adjust a height of a build space within a build container, the build container is adjustable in height and have a plurality of side walls;
wherein during a step of displacing the building platform, kinetic friction between the constructed layers and at least two side walls of the plurality of side walls is reduced or essentially avoided, wherein the building platform and the at least two side walls are moved at the same speed;
wherein a Z-axis drive unit positioned on a side of the build container drives the build container in a vertical direction, wherein the Z-axis drive unit is attached to a drive engagement of the build container, and wherein the only movement of the build platform during building of the three-dimensional objects is the vertical movement. - View Dependent Claims (23, 24)
