Three dimensional printing head, useful for melting and depositing layers of wire-shaped materials, comprises feed channel consisting of array of highly heat-conductive materials e.g. aluminum and low heat-conductive materials e.g. PTFE

摘要

The three dimensional printing head comprises a feed channel, which consists of an array of highly heat-conductive materials such as aluminum, copper, steel or graphite and low heat-conductive materials such as PTFE or polyetheretherketone, where the fed printing material has contact surfaces with the inside of these materials. An independent claim is included for a feed channel.
