Title: (EN) METHOD AND DEVICE FOR ASCERTAINING REQUIRED CONSTRUCTION MATERIAL
(ZH) 用于确定构造材料需求的方法和装置
Abstract: front page image
(EN) The invention relates to a method for providing required construction material information in the context of producing at least one three-dimensional object using a generative layer construction device, having the following steps: accessing data of a layer to be applied in a first data set in which for each layer to be applied during the production process, it is indicated whether construction material is to be solidified selectively in the layer and if so, at which locations in said layer the construction material is to be solidified; dividing the area (B) of the layer to be applied into sub-regions (110); assigning weighting factors to the sub-regions (110), and ascertaining a construction material quantity to be supplied to the coating device in order to apply the layer, wherein the construction material quantity is ascertained using the weighting factors assigned to individual sub-regions (110) and is provided as required construction material information.
(ZH) 本发明涉及一种用于在通过生成式逐层构造设备制造至少一个三维物体的情况下提供构造材料消耗信息的方法,所述方法至少具有以下步骤:访问第一数据集中的要施加的层的数据的步骤,在所述数据集中对于在制造期间要施加的每个层都标明了,在该层中是否应进行构造材料的选择性固化,并且如果应进行选择性固化,应在该层中的哪些位置使构造材料固化;将要施加的层的面(B)分成多个部分区域(110)的步骤;给所述部分区域(110)分配权重因数的步骤;确定供应给涂布机的构造材料的量以用于施加所述层的步骤,其中,根据分配给各个部分区域(110)的权重因数来确定构造材料的量,并且将其作为构造材料消耗信息提供。
