Patent Images
1. An extrusion head comprising:
- at least one mounting structure;
a first liquefier pump secured to the at least one mounting structure;
a second liquefier pump disposed adjacent to the first liquefier pump;
a toggle mechanism supported by the at least one mounting structure, and configured to move the second liquefier pump relative to the first liquefier pump along a first axis; and
a slot engagement mechanism connected in part to the second liquefier pump for defining a range of motion for the second liquefier pump along the first axis, wherein the slot engagement mechanism comprises a slot having a first perimeter and a second perimeter offset along the first axis and an engagement member disposed in the slot.

15. An extrusion head comprising:
-
at least one mounting structure; a motor secured to the at least one mounting structure; a threaded actuator operably secured to the motor, wherein the motor is configured to rotate the threaded actuator; a first liquefier pump secured to the at least one mounting structure, and comprising a first of a slot and an engagement member, the slot having a first perimeter and a second perimeter offset along a first axis; and a second liquefier pump threadedly engaged with the threaded actuator, wherein the second liquefier pump comprises a second of the slot and the engagement member, the engagement member being disposed in the slot between the first perimeter and the second perimeter, and wherein the rotation of the threaded actuator moves the second liquefier pump along the first axis. - View Dependent Claims (16, 17, 18, 19, 20)
