A powder bed fusion additive manufacturing process that utilizes the 2D Electrophotographic process found in laser printers and copy machines. Each layer of powder is created on a series of drums. Each drum picks up a pattern of powder for each material being used and can be a mixture of build and support materials. The process works just as a color 2D printer builds an image from colored toner powder.
That build layer is transferred from drum to drum, adding powder as it goes. The full layer is then transferred to a belt and which deposits the build layer powder on top of the previous layer. The layer is heated, and compressed, fused, then cooled. This results in a fully dense part with isotropic properties.
Abbreviated as STEP.
