Additive manufacturing system

An additive manufacturing system, comprising:

• a support;
• and
• a print head operatively connected to and moveable by the support, the print head including:
• a first module configured to discharge a path of material within a layer;
• a second module configured to compact the path of material with a compaction pressure as the path of material discharges from the first module;
• and
• a controller in communication with the second module and configured to:
• cause the second module to compact the path of material with a first force when the path of material is a sole path of material being compacted;
• and
• cause the second module to apply a second force that is greater than the first force when the path of material is being simultaneously compacted together with another path of material within the same layer by the second module, wherein the first and second forces cause the path of material to be compacted with a same pressure throughout the layer during discharge when the path of material is the sole path and when the path of material is being compacted together with the another path of material.

• a first module configured to discharge a path of material within a layer;
• a second module configured to compact the path of material as it discharges from the first module;
• and
• a controller in communication with the second module and configured to:
• cause the second module to exert a first force when the path of material is a sole path of material being compacted;
• and
• cause the second module to exert an incrementally increasing second force that is greater than the first force as a greater number of paths of material, including the path of material, are being simultaneously compacted, such that the path of material is compacted with a same pressure throughout the layer regardless of an existence of adjacent paths of materials being simultaneously compacted together with the path of material in the layer.
