- Small surface area between faces with 0.531 mm clearance: ● Hollow closed geometries. Multi Jet Fusion is a process in which the parts are built by selectively fusing the desired areas of a material-based layer. If the parts printed are hollow, the unfused material can either be trapped inside the fused walls of the part or drain holes need to be added to the design to remove the material. The minimum recommended diameter of the holes is 5 mm; preferably larger, for ease of cleaning. HP recommends including at least two holes. Minimum specification for parts 37
