But very soft materials, such as elastomers, need a tremendous amount of undercut. In fact, if the durometer of the material is extremely low, no amount of undercut will hold the sprue puller in place. These types of materials usually require either a Lollipop sprue puller or what is known as a Z-pin (Fig. 9).
