Embodiment Construction

[0060] According to the invention, a device or method is described for producing a three-dimensional model on a plane by means of a 3D printing method, wherein a material application device (such as a granular material coater unit or a print head unit) is provided in order to apply the respective material Apply to flat surfaces. The material application device is then moved vertically according to the invention on one or more portals.

[0061] Figure 1 to Figure 4 The scheme of the method of the invention according to a preferred embodiment is shown. At this point, on the plane 9 , the granular material is coated onto the plane 9 with the coater 4 . At this time, the coater 4 is included in the portal frame 1 . The gantry 1 moves on the plane of the linear unit 2 . The portal frame 1 then moves back into its initial position (see figure 2 ). The gantry 1' containing the print head 5 is now also independently movable on the linear unit 2 fixedly connected to the bottom s...

Abstract

The invention relates to a device for constructing models in layers. A region for constructing models, preferably a construction platform, and a material applying device (4, 5) for applying material onto the region are provided. The material applying device (4, 5) is arranged in a movable manner over the region. The material applying device (4, 5) is designed as a portal (1, 1') such that the material applying device can be moved over the region at least via two linear guides (2) arranged at opposite sides of the region, and the material applying device is arranged around the region such that a portal (1, 1') is formed by at least two portions that extend laterally with respect to the region. At least one additional material applying device (4, 5) for applying an additional material onto the region is provided.

Description

technical field [0001] The invention relates to a device and a device for layer-by-layer construction of a model according to the preamble of claim 1 or claim 8 . Background technique [0002] In European patent document EP0431924B1 a method for producing three-dimensional objects derived from computer data is described. In this case, a first material (here granular material) is applied in a thin layer onto a build platform, optionally covered with a container, and a second material, which can form a solid object with the first material, is subsequently applied thereon. Two materials. For example, according to EP0431924B1, a granular material is provided as a first material and then selectively printed by means of a printing head with a bonding material. The particle regions printed with the binder are bonded and cured under the influence of the binder and optionally additional curing agents. The platform is then lowered one layer thick into the build cylinder and a new l...
