Abstract An improved collet and method for dispensing viscous materials is described in which a quill having a fluted insert comprise end portions having a small radius of curvature. The viscous material is extruded from the collet, brought into contact with the article on which the material is to be deposited, and then removed leaving a hollow figure of material having approximately the same shape as the cross-section of the quill.
