A dispense tip constructed and arranged to communicate with a material dispensing pump comprises an elongated neck and a molded base having a first portion and a second portion opposite the first portion. The neck extends from the first portion of the base. The second portion is constructed and arranged to abut an outlet surface of the pump. An outermost region of the second portion of the base includes a compressible fluid-tight surface that compliantly conforms to the outlet surface when the dispense tip is mounted to the pump.

1. A dispense tip constructed and arranged to communicate with a material dispensing pump, the dispense tip comprising: an elongated neck; anda molded base having a first portion and a second portion opposite the first portion, the second portion having a same width as the first portion, the neck extending from the first portion of the base, the second portion constructed and arranged to abut an outlet surface of the pump, an outermost region of the second portion of the base including a compressible fluid-tight surface that compliantly conforms to the outlet surface when the dispense tip is mounted to the pump. 2. The dispense tip of claim 1, wherein the neck comprises molded materials. 3. The dispense tip of claim 1, wherein the neck comprises ceramics. 4. The dispense tip of claim 1, wherein the neck comprises stainless steel. 5. The dispense tip of claim 1, wherein the second portion of the base comprises polyarylene sulfide. 6. The dispense tip of claim 5, wherein the polyarylene sulfide is polyphenylene sulfide. 7. The dispense tip of claim 6, wherein the polyphenylene sulfide is linear and partially crystalline. 8. The dispense tip of claim 1, wherein the first and second portions of the base comprise polyarylene sulfide. 9. The dispense tip of claim 1, wherein the base is coupled to the neck by bonding the base to the neck with a bonding material. 10. The dispense tip of claim 9, wherein the bonding material includes a two-part epoxy. 11. The dispense tip of claim 1, wherein the dispense tip is constructed and arranged to communicate with a fixed-z material dispensing pump. 12. The dispense tip of claim 1, wherein the dispense tip is constructed and arranged to communicate with a floating-z material dispensing pump. 13. The dispense tip of claim 1, wherein the neck comprises: an elongated hole that extends from an input end of the neck to an output end of the neck; andan inner taper between the input end of the neck and the output end of the neck that transitions the input end to the output end. 14. The dispense tip of claim 13, wherein a portion of the elongated hole has an inner surface of a first inner diameter and the output end includes an outlet having an inner surface of a second inner diameter, the first inner diameter being greater than the second inner diameter. 15. The dispense tip of claim 1, wherein the base includes a funnel that delivers fluid to the neck, the funnel having a funnel inlet at an input end of the funnel and a funnel outlet at an output end of the funnel, wherein the neck communicates with the funnel outlet such that the dispense tip includes a single material path between the funnel outlet and an output end of the neck. 16. The dispense tip of claim 1 further comprising an alignment foot coupled to the base, the foot having a primary axis substantially parallel to a longitudinal axis of the neck, and being of a length longer than the neck. 17. The dispense tip of claim 1 further comprising a plurality of elongated necks, each neck coupled to the first portion of the base, the base including a single funnel, each neck including a hole having a single input end and a single output end, the input end communicating with the funnel such that each neck includes a single fluid path between the funnel and the output end of the neck. 18. The dispense tip of claim 1, further comprising a chamfer at the second portion of the base. 19. The dispense tip of claim 18, wherein the chamfer is at the outermost region of the second portion of the base. 20. A dispense tip constructed and arranged to communicate with a material dispensing pump, the dispense tip comprising: an elongated neck; anda base coupled to the neck, the base including a compressible surface such that a fluid-tight interface can be formed between the compressible surface of the base and the pump by compliantly conforming the base to the pump when the dispense tip is mounted to the pump, wherein the compressible surface of the base comprises polyarylene sulfide, wherein the base has a first portion and a second portion opposite the first portion, the neck extending from the first portion of the base, the second portion comprising the compressible surface. 21. The dispense tip of claim 20, wherein the polyarylene sulfide is polyphenylene sulfide. 22. The dispense tip of claim 21, wherein the polyphenylene sulfide is linear and partially crystalline. 23. The dispense tip of claim 20, wherein the first and second portions have a same width. 24. The dispense tip of claim 20, wherein the first and second portions of the base comprise polyarylene sulfide. 25. The dispense tip of claim 20, wherein the dispense tip is constructed and arranged to communicate with a fixed-z material dispensing pump. 26. The dispense tip of claim 20, wherein the dispense tip is constructed and arranged to communicate with a floating-z material dispensing pump. 27. The dispense tip of claim 20, wherein the neck comprises: an elongated hole that extends from an input end of the neck to an output end of the neck; andan inner taper between the input end of the neck and the output end of the neck that transitions the input end to the output end. 28. The dispense tip of claim 27, wherein a portion of the elongated hole has an inner surface of a first inner diameter and the output end includes an outlet having an inner surface of a second inner diameter, the first inner diameter being greater than the second inner diameter. 29. The dispense tip of claim 20, wherein the base includes a funnel that delivers fluid to the neck, the funnel having a funnel inlet at an input end of the funnel and a funnel outlet at an output end of the funnel, wherein the neck communicates with the funnel outlet such that the dispense tip includes a single material path between the funnel outlet and an output end of the neck. 30. The dispense tip of claim 20 further comprising an alignment foot coupled to the base, the foot having a primary axis substantially parallel to a longitudinal axis of the neck, and being of a length longer than the neck. 31. The dispense tip of claim 20 further comprising a plurality of elongated necks, each neck coupled to the first portion of the base, the base including a single funnel, each neck including a hole having a single input end and a single output end, the input end communicating with the funnel such that each neck includes a single fluid path between the funnel and the output end of the neck. 32. The dispense tip of claim 20, further comprising a chamfer at the base. 33. The dispense tip of claim 32, wherein the chamfer is about at least a portion of the compressible surface.
