Video: Metal AM Affects Plastics Production via Conformal Cooling
Additive manufacturing allows cooling channels within mold tooling inserts to follow the form of the tool rather than being straight drilled holes. Here’s why this matters.

Video: The Impact of Part Orientation on Cost and Build Time in AM
A different build orientation might mean fewer layers and less support structure, though the part might need to be redesigned to take advantage of this different orientation.
