Beam Deposition Processes
Beam deposition (BD) processes enable the creation of parts by melting and deposition of material from powder or wire feedstock. Although this basic approach can work for polymers, ceramics, and metal matrix composites, it is predominantly used for metal powders. Thus, this technology is often referred to as “metal deposition” technology. To avoid limiting the readers’ understanding to just metal build materials, however, we will refer to this category of processes as beam deposition processes.
BD processes use some form of energy focused into a narrow region (a beam), which is used to heat a material that is being deposited. Unlike the powder bed fusion techniques discussed in Chap. 5, BD processes are NOT used to melt a material that is pre-laid in a powder bed but are used to melt materials as they are being deposited.
