Abstract
A syringe tip assembly comprising a seal component configured to engage a syringe tip, a nozzle configured to slidably engage with the seal component, and a biasing member configured to apply a biasing pressure between the seal component and the nozzle.
Claims20
A syringe tip assembly for use with an extrusion syringe of a layered deposition system, the syringe tip assembly comprising:
- a seal component configured to engage a syringe tip of the extrusion syringe;
- a nozzle configured to slidably engage with the seal component;
- and
- a biasing member configured to apply a biasing pressure between the seal component and the nozzle.
A syringe deposition tool comprising:
- a frame having a base wall;
- a motor;
- a syringe having a syringe body, a syringe tip, and a piston, wherein the piston is operably secured to the motor;
- and
- a syringe tip assembly disposed around at least a portion of the syringe tip and engagable with the base wall of the frame, the syringe tip assembly being configured to compress when the motor applies a pressure on the piston.
A method of building a three-dimensional object with a syringe deposition tool of a layered deposition system, wherein the syringe deposition tool includes an extrusion syringe and a syringe tip assembly, the method comprising:
- applying pressure to a piston of the extrusion syringe;
- compressing a biasing member of the syringe tip assembly due to the pressure applied to the piston,
- moving the piston through a syringe body of the extrusion syringe after at least partially compressing the biasing member, wherein moving the piston through the syringe body extrudes a material through the syringe tip assembly;
- and
- removing at least a portion of the pressure applied to the piston to at least partially decompress the biasing member.
