METHOD FOR CALCULATING SUPPORT STRUCTURES AND SUPPORT ELEMENTS FOR ATTACHING A SUPPORT STRUT OF SAME

摘要

Method for calculating support structures, consisting of support struts, for a three-dimensional layered object on a platform, comprising: for each layer, determining a surface of the layer that is open in relation to a lower layer, and determining support points, on which the layer is to be supported; assigning a respective cone to each support point, with each cone located with the cone tip in the respective support point and opening toward the platform; forming groups of support points of all layers to be supported, with each group being assigned all of the support points, the cones of which forming overlaps with other cones of other support points; and for each group, calculating at least one support structure, with one support strut ending in each support point of each group, and the support structure standing on the platform or on a portion of the object lying below the group.

1. A method for calculating one or more support structures, consisting of support struts, for a three-dimensional object on a platform, which object is built up from layers by a manufacturing process, comprising:
for each layer of the object, determining a surface of the layer that is open in relation to a layer located therebelow, and determining support points, on which the layer is intended to be supported, within the determined surface; assigning a respective cone to each support point, with each cone being located with the cone tip in the respective support point and opening in the direction of the platform; forming groups of support points of all of the layers to be supported, with each group being assigned all of the support points, the cones of which forming overlaps with other cones of other support points; and for each group, calculating at least one support structure, with one support strut ending in each support point of each group, and the support structure standing on the platform or on a portion of the object lying below the group.
