Abstract
An additive manufacturing system for producing a component includes a deposition assembly having a deposition head through which melted feedstock material is deposited, and a compression rig comprising a compression head supporting an inside roller, an outside roller opposing the inside roller, and a top roller, the inside roller applying a compressive load onto an interior side surface of the component, the outside roller applying a compressive load onto an exterior side surface of the component, and the top roller applying a compressive load onto a top surface of the component.

An additive manufacturing system for producing a component, the additive manufacturing system comprising:
- a deposition assembly having a deposition head through which melted feedstock material is deposited;
- and
- a compression rig comprising a compression head supporting an inside roller, an outside roller opposing the inside roller, and a top roller, the inside roller applying a first compressive load onto an interior side surface of the component, the outside roller applying a second compressive load onto an exterior side surface of the component, and the top roller applying a third compressive load onto a top surface of the component;
- and
- a lever system comprising:
- a first pivot segment provided at a proximal end of a compression actuator;
- a second pivot segment provided at an opposite distal end of the compression actuator;
- a first linkage member pivotally coupling the first pivot segment to the outside roller;
- and
- a second linkage member pivotally coupling the second pivot segment to the inside roller,
- wherein, when a length of the compression actuator increases, a distance between the outside roller and the inside roller decreases,
- wherein, when the length of the compression actuator decreases, the distance between the outside roller and the inside roller increases,
- wherein the deposition head and the compression head are configured to move independently of one another in a circumferential direction about the component.
An additive manufacturing system for producing a component, the additive manufacturing system comprising:
- a rotary build table rotatable about a vertical axis of the rotary build table, the rotary build table defining a horizontal build surface on which the component is built;
- a deposition assembly having a deposition head through which melted feedstock material is deposited;
- a compression rig comprising a compression head positionable proximate to the deposition head, the compression head supporting an inside roller, an outside roller opposing the inside roller, and a top roller, the inside roller applying a first compressive load onto an interior side surface of the component, the outside roller applying a second compressive load onto an exterior side surface of the component, and the top roller applying a third compressive load onto a top surface of the component;
- and
- a controller communicably coupled to the deposition assembly and the compression rig, wherein the controller is configured to independently control application of the first compressive load, the second compressive load, the third compressive load, and any combination thereof, as the deposition head deposits melted feedstock material;
- and
- a lever system comprising:
- a first pivot segment provided at a proximal end of a compression actuator;
- a second pivot segment provided at an opposite distal end of the compression actuator;
- a first linkage member pivotally coupling the first pivot segment to the outside roller;
- and
- a second linkage member pivotally coupling the second pivot segment to the inside roller,
- wherein, when a length of the compression actuator increases, a distance between the outside roller and the inside roller decreases,
- wherein, when the length of the compression actuator decreases, the distance between the outside roller and the inside roller increases,
- wherein the deposition head and the compression head are configured to move independently of one another in a circumferential direction about the component.
