1. A dispenser, comprising:
a material feed portion configured to provide a printing material;
a coolant source, wherein the coolant source comprises a coolant;
a cold end portion, wherein
the cold end portion comprises a helical core having a conduit,
the coolant from the coolant source passes through the conduit of the helical core to cool down a temperature of the printing material,
the helical core of the cold end portion is configured to:
receive the coolant from a bottom of the helical core of the cold end portion, and
maintain a helical flow of the coolant in the helical core of the cold end portion and exits the coolant from a top of the helical core;
a hot end portion; and
a material passage insert, wherein
the hot end portion and the cold end portion is a two-piece structure joined together through the material passage insert, wherein
a first part of the material passage insert is in the hot end portion and made of aluminium, a second part of the material passage insert is lying between the cold end portion and the hot end portion, the second part of the material passage insert is made up of a material with thermal conductivity to restrict the heat transfer from the hot end portion to the cold end portion, and a third part of the material passage insert is in the cold end portion, the third part of the material passage insert is configured to transfer a heat from the material passage insert into the helical core of the cold end portion.
