13. An additive manufacturing device comprising:
-
a receptacle configured to receive a print head, the receptacle comprising a first sloped surface, the first sloped surface comprising a first longitudinal axis wherein a cross section of the first sloped surface taken substantially perpendicular to the first longitudinal axis comprises a circle; a print head configured to be positioned within the receptacle, the print head comprising a second sloped surface having a second longitudinal axis, wherein a cross-section of the second sloped surface taken substantially perpendicular to the second longitudinal axis comprises a circle, and wherein the second sloped surface is configured to engage the first sloped surface as the print head is positioned within the receptacle such that lateral movement of the print head relative to the receptacle is minimized; and a securing mechanism in communication with the receptacle, the securing mechanism comprising spaced apart upper and lower surfaces configured to engage the print head to inhibit vertical movement of the print head within the receptacle. - View Dependent Claims (14, 15)
