Abstract
A cutting system for removing an excess material along a length of a channel constructed using an additive manufacturing process is disclosed. In various embodiments, the cutting system includes a cutting component having an abrasive surface configured to remove the excess material along a down-facing surface of the channel and a smooth surface configured for sliding contact with an up-facing surface of the channel; and a motive component configured to urge the cutting component through the channel.

A cutting system for removing an excess material along a length of a channel constructed using an additive manufacturing process, comprising:
- a cutting component having a rough surface configured to remove the excess material along a down-facing surface of the channel resulting from the additive manufacturing process and a smooth surface configured for sliding contact with an up-facing surface of the channel resulting from the additive manufacturing process;
- and
- a motive component configured to urge the cutting component through the channel,
- wherein the cutting component comprises at least one of PTFE or UHMW,
- wherein the rough surface comprises at least one of silica or diamond embedded into the cutting component.
A cutting system for removing an excess material along a length of a channel constructed using an additive manufacturing process, comprising:
- a cutting component having a first means configured to remove the excess material along a down-facing surface of the channel resulting from the additive manufacturing process and a second means configured for sliding contact of the cutting component with an up-facing surface of the channel resulting from the additive manufacturing process;
- and a motive component configured to urge the cutting component through the channel,
- wherein the second means comprises a smooth surface comprising at least one of PFTE or UHMW,
- wherein the first means comprises a rough surface comprising at least one of silica or diamond embedded into the cutting component.
