Claims18
A head for an additive manufacturing system, comprising:
- an outlet configured to discharge a continuous reinforcement at least partially coated in a liquid matrix;
- and
- a low-pressure port located upstream of the outlet and configured to draw out only liquid matrix.
An additive manufacturing system, comprising:
- a print head configured to discharge a continuous reinforcement at least partially coated with a liquid matrix, the print head having at least one low-pressure port located upstream of an outlet;
- a pump fluidly connected to the low-pressure port and configured to drawn liquid matrix through the low-pressure port;
- a support configured to move the print head during discharging;
- and
- a controller in communication with the print head, the support, and the pump, the controller configured to adjust a pressure applied to the low-pressure port by the pump during multiple modes of operation.
