    摘要: A liquefier assembly for use in an additive manufacturing system, which includes a rigid member having a gap, a liquefier tube operably disposed in the gap, one or more heater assemblies disposed in the gap in contact with the liquefier tube, and configured to heat the liquefier tube in a zone-by-zone manner, preferably one or more thermal resistors disposed in the gap between the rigid member and the heater assemblies, and preferably one or more sensors configured to operably measure pressure within the liquefier tube. The one or more heater assemblies may be operated to provide dynamic heat flow control.

    摘要: Method for making multiple durometer bulb seals includes cooling separately at least one structural member and at least one bulb portion of the bulb seal, which have different durometers and shapes. At least a first extrusion is drawn through a die of an extruder for forming a structural member profile and the extruded material is pulled by a first pulling device along a longitudinal axis to a first calibrator device and then through a first cooling tank to cool the structural member profile to a predetermined temperature. Cooling medium directly contacts the outer and inner surfaces of the first profile. The bulb portion is extruded and attached onto the cooled structural member and pulled downstream to a second calibrator device and through a second cooling tank to cool the profile a predetermined amount. Disparity in cooling expansion and cooling differential between the multiple durometers and shapes is avoided or overcome.
