METHOD FOR ADDITIVELY MANUFACTURING COMPONENTS

An example method of making a component includes providing a digital model of a component to software, the software operable to slice the model into layers and raster each layer into segments, the segments delineated by raster lines. The method further includes depositing a layer of powder onto a pl...

Zusammenfassung:	An example method of making a component includes providing a digital model of a component to software, the software operable to slice the model into layers and raster each layer into segments, the segments delineated by raster lines. The method further includes depositing a layer of powder onto a platform, compacting the layer of power into a compacted layer, sintering the compacted layer along lines corresponding to the raster lines using a laser, wherein the laser operates at a first power and a first scan speed, the first power being between about 200 and 230 W, then sintering the compacted layer along a perimeter of the compacted layer using the laser to form a unitary layer, wherein the laser operates at a second power and a second scan speed, the second power being between about 100 and 200 W. An apparatus for making a component is also disclosed.
