Abstract
A three-dimensional (3D) printing system may comprise a frame; and an additive component(s) configured to couple to the frame. The additive component(s) may comprise a first extrusion unit, a second extrusion unit, and/or a third extrusion unit. The 3D printing system may be a portion of a hybrid computer numerical control (CNC) machining/3D printing system and configured to manufacture a 3D component autonomously from start to finish. The additive component(s) may comprise a heating system including a hot-air blower.
Claims20
A fiber embedding extrusion unit for use in a 3D printing system, comprising:
- a drive motor;
- an auger coupled to the drive motor;
- a housing assembly, the auger disposed within the housing assembly, the auger configured to translate a material to be deposited through the housing assembly;
- a hopper in fluid communication with the housing assembly;
- a heating system coupled to the housing assembly, wherein the heating system is configured to heat a deposited layer prior to depositing a second layer;
- at least one of a mount or an actuator, wherein at least one of the mount or the actuator can be removably coupled to a computer numerical control (CNC) machining device;
- and
- a spool feeder system configured to feed a fiber into the housing assembly and intersect with the material to be deposited upstream from an outlet of the auger.
