An injection molded laser cutting nozzle tip made from an electrically conductive polymer is provided. The laser cutting nozzle tip includes sacrificial engineering elements in order to provide structural failure of the inexpensive nozzle while preserving intact other more costly components of the laser, in the event the nozzle tip inadvertently comes into forcible contact with a work piece. Suitable electrically conductive polymers include, but are not limited to, polyphenylene sulfide (PPS), polyaniline, polythiophene, polypyrrole, and polyacetylene.
