Abstract

Additive manufacturing continues to offer new possibilities in both production and economics. The industry has quickly adopted it to rapidly produce parts that would be difficult or cost preventative otherwise. Recent innovation has expanded its capabilities, however there are still significant limitations. Most AM processes are restricted by materials available, in producing large parts, or by not achieving material deposition speeds to make certain products feasible. In addition, tight tolerances for features and surfaces cannot be produced without substantial post processing. High-speed Fused Pellet Fabrication (FPF) in combination with Hybrid Manufacturing (HM) offers expanded capabilities as additive and subtractive process are used within the same space. It also allows for a different kind of additive process where an open mold can be cut from a substrate and then filled using the FPF process to fabricate parts without layers. This, in combination with Large Area Additive Manufacturing (LAAM), enables parts that leverage the strengths of new and traditional methods at scales and speeds previously unavailable.
