Abstract:
1. A dispense tip comprising: an elongated neck having a longitudinal axis; an elongated hole in the neck, the hole extending from an input end region of the neck to an output end region of the neck, a portion of the elongated hole having an inner surface of a first inner diameter, and the output end region including an outlet having an inner surface of a second inner diameter, the first inner diameter being greater than the second inner diameter, wherein the outlet having the inner surface of the second inner diameter has a first length in a direction along the longitudinal axis; an inner taper that transitions the inner surface of the hole from the first inner diameter at a first position relative to the longitudinal axis to the second inner diameter at a second position relative to the longitudinal axis; a body at the input end region of the neck, the body including a funnel that delivers fluid to the input end region of the neck, the dispense tip constructed and arranged to receive a flow of the fluid from a material pump during a dispensing operation, the funnel having a funnel inlet at an input end of the funnel that is constructed and arranged to receive the flow of the fluid from the material pump and a funnel outlet at an output end of the funnel, the funnel having a smooth tapered inner surface that continuously narrows in diameter in a direction from the funnel inlet to the funnel outlet, wherein the input end region of the neck communicates with the funnel outlet such that the dispense tip includes a single fluid path between the funnel inlet and the output end region of the neck, wherein at least one of the neck and the body of the dispense tip comprises ceramics, and wherein the fluid path only narrows in diameter or remains constant in diameter from the funnel inlet to the first position of the inner taper along the longitudinal axis; a bevel about an outermost end of the output end region of the neck, wherein the outlet extends from the inner taper to the outermost end, and wherein the bevel lies at an acute angle relative to the longitudinal axis at the outermost end of the output end region of the neck; and the neck having an outer surface that is linear in extension between the first position of the inner taper and the bevel.
