• For mating parts (such as a cope and drag of the same mold), try to always print them in
the same orientation in the build.

6.14 Degassing and Filtering Metal
To help achieve improved part quality, steps should be taken to properly
prepare the metal for pouring. Two typical foundry practices are degassing
and filtering. When properly taken, these steps help to yield quality parts in
any foundry.
Filters can be added directly to the mold. This can be accomplished by
strategically locating filters within the drag assembly as shown in Figure 13.
Design slots or shelves in the drag for filter placement. Other options
include using foundry consumables with ceramic inserts as shown in Figure 12.
Accumulated slag on the top of the crucible should be removed prior to pouring.
