SELECTIVE CURING ADDITIVE MANUFACTURING METHOD

A method for producing a component layer-by-layer include the steps of: depositing a layer of particulate material having a first area over a build platform; applying a radiant-energy-curable binder to the layer so that a selected portion of the first area is uniformly coated with binder; selectivel...

Zusammenfassung:	A method for producing a component layer-by-layer include the steps of: depositing a layer of particulate material having a first area over a build platform; applying a radiant-energy-curable binder to the layer so that a selected portion of the first area is uniformly coated with binder; selectively curing a second area of the layer smaller than the selected portion of first area, using an application of radiant energy in a specific pattern that defines the geometry of a cross-sectional layer of the component; and repeating the steps of depositing, applying, and curing for a plurality of layers until the component is complete. 种用于逐层生产部件的方法包括以下步骤：在构建平台上沉积层具有第区域的颗粒材料；将辐射能可固化的粘合剂施加到层上，以使得第区域的选择部分均匀地涂布有粘合剂；以限定所述部件的横截面层的几何形状的特定图案，施加辐射能选择性地固化小于第区域的选择部分的层的第二区域；以及对多个层重复沉积，施加和固化的步骤直到部件完成。
