Abstract
The invention relates to a device and method for preparing a structure or object using an additive manufacturing process referred to as sequential cold spray laser sintering. The method includes depositing by cold spraying a plurality of sequential layers of material onto a substrate/build plate or particles of materials onto a compacted powder bed of material and employing an energy source to sinter or melt each of the plurality of sequential layers or powders to produce sequential sintered layers, wherein the number of additional layers is determined based on those needed to produce the final structure.
